Description

Disc-shaped deburring tool

The invention relates to a disk-shaped deburring tool for shearing off burrs projecting over the front side of gear wheels with at least one cutting edge assigned to the disk broad side.

DE 36 08 458 Cl shows an embodiment in which bevel wheels are provided with coaxially arranged deburring disks. Radial pressure of the folding wheels on the work wheel or on the tooth flanks of the same causes flanks to be flipped to the face of the gear wheel. By means of the deburring disks which overlap at the edge of the work wheel, the secondary burr which is produced there is removed, which is very small and adheres to the deburring wheel in particular as chips. The deburring tool is magnetized during machining due to the friction of the cutting edge on the face of the work wheel. As a result, steel shavings adhere to the deburring tool and must be removed.

The object of the invention is based on the further development of a generic deburring tool in an advantageous manner.

This object can be achieved in various ways in a generic configuration. An embodiment according to the invention is characterized by an inhomogeneous edge region of the disk having at least one cutting edge.

As a result, the formation or build-up of magnetism is inhibited or prevented when the work wheel is machined by the deburring tool. As a result of the inhibition of the magnetic flux, the adhesion of steel chips to the deburring tool is largely eliminated. To- Parts resulting from adhering chips on the deburring tool are thereby eliminated. It is Z. B. not necessary to remove swarf from the deburring disc using rinsing liquid. The deburring process can therefore be made cleaner. One way to achieve this inhomogeneity is that the edge of the disk is slotted, in particular with a plurality of slits running in the radial direction and open towards the edge. Such an embodiment can be created inexpensively. Furthermore, inhomogeneity can be achieved through holes assigned to the edge of the pane or material thickening / reduction. In this regard, an advantageous alternative is characterized by ribs / grooves extending in the form of spokes up to the edge. Accordingly, there are elements of different strengths for inhibiting the magnetic flux, which elements have a radial orientation.

To solve the problem of the invention in a generic embodiment, it can also be provided that the disc consists of different materials, the cutting edge made of magnetic steel and a cutting support body made of non-magnetic material. This composition also leads to an inhibition of the magnetic flux due to the non-magnetic blade support body. The cutting edge, which is made of magnetic steel, is assigned to this, so that overall a deburring tool that is inexpensive to produce results. It is thus possible for the at least one cutting edge to be formed by a ring. Tool steel known per se is used for the ring. In order to obtain an interchangeability of the ring, it can have a T or L cross-section and can be pressed onto the edge of the disk-shaped cutter support body. The ring forms a circumferential cutting edge. Alternatively, the ring can also have a milling cut. An adjustability or readjustment can be realized in that the cutting edge is a clamped, conically shaped or deformed ring. WEI It is also possible to design the cutting edge in the form of a ring plate, which is similar in structure to a plate spring. The rim of the plate therefore forms the circumferential cutting edge. Instead of a circumferential ring which forms the cutting edge, a plurality of individual cutting edges can also be provided, which are assigned to the broad side of the cutting edge in a radial or secant shape. These individual cutting edges are assigned to the cutting support body in a corresponding orientation. There is therefore an interrupted cut during processing, the individual cutting edges counteracting magnetization and leading to an inhibition of the magnetic flux. Since the individual cutting edges have an inclined inlet in the corner area, bumping when a new individual cutting edge is engaged is avoided, which is characterized by a smooth rotation of the work wheel during machining. It is particularly useful to design the individual cutting edges as indexable inserts. After the relevant cutting edge in use has been worn, turning can then be carried out so that the service life of the individual cutting edges can be increased. The individual cutting edges can be assigned to the disk-shaped cutting support body in such a way that a large number of the individual cutting edges tangent to a common inner circle.

To achieve the object of the invention, a plurality of circumferential cutting edges running concentrically to the axis of rotation can also be provided in a generic configuration. This configuration also achieves an inhibition of the magnetic flux, which counteracts the adherence of steel chips to the deburring tool. This configuration is particularly suitable for work wheels with a large residual burr from the preprocessing, that is, the gear cutting of the work wheels. Alternatively, the circumferential edges can be at different levels. Such a configuration is particularly advantageous in which the cutting edge height increases from the edge to the center of the disk. Basically it is possible with this version, the to arrange relevant circumferential edges in sectors on the circumference. The deburring tool can also be used with or without a drive.

To solve the problem of the invention in a generic configuration, a plurality of concentrically or radially extending cutting edges can then be provided, with depth limits arranged between two cutting edges. Due to the recessed depth limits compared to the cutting edges, magnetization is also prevented. The depth limits prevent the cutting edges from penetrating too deeply or getting caught on the front of the work wheel. The depth limits represent in particular a stop tooth and are designed so that they have no cutting effect. This looks like the cutting of teeth and the depth limits are formed by blunt protrusions.

A further possibility of solving the object of the invention in a generic design is to provide a plurality of cutting edges which run in a secant shape to the axis of rotation and which are crossed by channels running in a secant shape. In this embodiment, magnetization is also prevented due to an inhomogeneity of the disk on the edge. This is optimized by the channels crossing the cutting edges. These then fulfill a double function in that, in addition to promoting inhomogeneity, they represent chip transport grooves through which the steel chips can leave the deburring tool. These chip transport grooves have a similar effect to the grooves provided on grinding disks. In addition, the chip transport grooves can take different angles to each other and to the deburring tool.

Finally, in order to solve the task of the invention in a generic design, it can also be provided that the circumferential direction Cutting edge has a multiplicity of radial niches, adjacent radial niches meeting in an edge line, each of which forms a corner with the cutting edge. The radial niches lead to a shaped circumferential surface of the cutting tool. The circumferential surface is preferably aligned with a truncated cone surface, the radial niches forming sharp-edged edge lines as in the case of a wave wheel with “bread knife” grinding. In connection with the cutting edge, the deburring tool works with an interrupted cut while simultaneously inhibiting the build-up of magnetism What is particularly advantageous about this configuration is the fact that the deburring tool is less sensitive to residual burr from hobbing, since a cutting movement is produced in the circumferential direction. The radial niches are advantageously designed in the form of grooves, the latter being symmetrical or asymmetrical be designed.

Fig. 25 shows a modification of the fifteenth embodiment, namely with differently designed throats. The device illustrated in FIGS. 1 to 3 is suitable for receiving deburring tools according to the invention. The device contains suction nozzles 6, 7, 9, compressed air nozzles 10, 11 and a demagnetizing device 15.

The work wheel, which is a circumferentially toothed gear, is driven in rotation about an axis of rotation 18. The tooth flanks have been reworked, for example, by folding. This creates burrs that should be removed with the device. For this purpose, a folding wheel designated with the reference number 2 is fed to the work wheel 1 in the radial direction. The folding wheel 2 is seated on a feed arm 12 which can be pivoted in the direction of the double arrow about an axis of rotation (not shown). In the exemplary embodiment, two folding wheels 2 lie in parallel to one another in order to deburr each of the two tooth flank end regions. There, the bevel gears 2 engage with their toothings 20 in the toothings 19 of the work wheel 1. As a result of a radial pressure, burrs there are pressed outwards over the end face of the work wheel. The secondary burrs thus created are removed with a deburring tool designed as a deburring wheel 3.

The deburring wheel 3 is also seated on a feed arm 14 which can be pivoted about an axis (not shown) in the direction of the double arrow. By means of a tooth engagement or frictional engagement, the deburring wheel 3 is dragged along by the gear wheel 1. In the exemplary embodiment, two deburring wheels 3 lying parallel to one another are provided, which shear off the secondary burrs formed with their cutting edges 22 resting on the gear wheel end faces.

The reference number 8 denotes the end of a suction line. A replaceable head piece 9 is flanged onto the end of the same. This forms fork F-shaped suction nozzles 6, 7, which protrude into the respective gusset between the gear 1 and the two tool wheels 2, 3. The mouth of the suction nozzles 6, 7 is located directly on the processing area 4 between the folding wheel 2 and the gear 1 or the working area 5 of the deburring wheel 3 on the gear 1. Instead of, as shown, the suction nozzle 6 could be extended in relation to the suction nozzle 7 be formed so that the suction nozzle 6 points in the opposite gusset and thus against the direction of rotation. The shavings sheared by the deburring wheel 3 from the end face of the gear 1 are sucked off by the suction nozzle 7. The suction nozzle 7 or the suction nozzle 6 can be designed such that it sucks off the two working areas lying one above the other in FIG. 2.

The head piece 9 is interchangeably assigned to the suction line 8. Other head pieces 9 can be used, in which the distance between the two suction nozzles 6, 7 varies in order to be able to relax work wheels of a different diameter with the device.

The deburring tool or deburring wheel 3 rotates in the area of the working area 5 in the suction direction of the suction nozzle 7. The deburring wheel 3 also rotates in the direction of the blowing direction of a compressed air nozzle 10, which permanently blows in between the gear 1 and the deburring wheel 3. The compressed air nozzle 10 is accordingly in the area of the gusset, which is arranged opposite the gusset of the suction nozzle 7.

While the compressed air nozzle 10 is operated permanently and is adjustable to the device with regard to different work wheel diameters, a compressed air nozzle 11 is only actuated at intervals. The compressed air jet that escapes from the compressed air nozzle 11 is tangential in the direction of rotation to the teeth 20 of the folding wheel 2 directed. This compressed air nozzle 11 is assigned to the feed arm 12 of the folding wheel 2, specifically by means of a tab 13.

The reference number 15 denotes a demagnetizing device. The same sits on the infeed arm 14 of the deburring tool 3. As can be seen in particular in FIG. 3, the demagnetizing device 15 forms two slots 17 through which the edge regions of the two deburring tools 3 arranged parallel to each other pass. The edge areas of the deburring wheels 3 are immersed by an alternating electromagnetic field, so that the deburring wheel 3 is demagnetized. Any chips adhering to the deburring wheel 3 then lose their adhesion to the deburring wheel 3 and can be blown off using compressed air. The deburring wheel 3 preferably dips contactlessly through the slot 17. However, mechanical removal of the chips could also be provided here.

A demagnetizing device 15 could be dispensed with if a deburring tool 3 according to FIG. 4 is used, which FIG. 4 relates to the first embodiment of the deburring tool. According to this configuration, the disk-shaped deburring tool is composed of different materials. The cutting edge is formed by a ring and is made of magnetic steel. This ring is received by a non-illustrated disk support body made of non-magnetic material. The edge of the disk 3, here the ring, is slotted with a multiplicity of slots 23 which run in the radial direction and open towards the edge. Holes 24 extend between two slots 23 in each case. The outward-pointing open radial slots 23 lead to an interruption in the cutting edge , Due to the radial slots 23 and holes 24, an inhomogeneous edge region of the disk or deburring tool is created, which leads to inhibition of the magnetic flux. Sheared steel chips can therefore not adhere to the deburring tool 3 at all or only insufficiently.

An inhomogeneity could also be caused by corresponding material thickening or reduction in the edge area of the pane 3.

The device operates as follows: To load the device with a work wheel 1, the two tools, the folding wheel 2 and the deburring wheel 3 are moved apart in the radial direction of the workpiece axis 8. This is done by pivoting the feed arms 12, 14. If the work wheel 1 is brought into position, the tools 2, 3 are fed radially until the toothing 20 of the folding wheel 2 engages in the toothing 19 of the work wheel 1. The deburring wheel 3 is entrained by frictional engagement with the work wheel 1 or by engagement of a drive toothing 25 of the deburring wheel in the toothing 19 of the work wheel 1. Burrs in the toothing 19 are expressed by exerting a radial pressure of the folding wheel 2 on the work wheel 1. Secondary burrs arise over the respective end face of the work wheel 1. These are sheared off by the deburring wheel 3. This is done by the cutting edge 22 which is acted upon in the axial direction on the broad surface of the gear 1.

In order to remove the swarf created during the burr removal, a local vacuum is generated in the area of the suction nozzles 6, 7. The air flowing into the suction nozzles 6, 7 contains chips which can subsequently be extracted from the suction air. The compressed air nozzle 10, which is directed into the gusset between the work wheel 1 and the deburring wheel 3, serves to support the chip transport in the direction of the suction nozzle 7. If the demagnetizing device 15 is used in the device, this additionally prevents the formation of a magnetic flux on the deburring tool 3. 5 shows the second embodiment of a disk-shaped deburring tool 3. There is no two-part system there. The edge area of the disc, which is made of tool steel, is slotted with a plurality of slots 27 which run in the radial direction and open towards the edge. These lead to an inhomogeneity in the edge area of the disc and accordingly inhibit the build-up of magnetism when machining work wheels. If necessary, a thickening or reduction in material could also be provided in this version between two adjacent radial slots 27.

The third embodiment illustrated in sections in FIGS. 6 and 7 shows a disk-shaped deburring tool 3 with material thickenings / reductions on the edge. In a circumferential collar 28 there are a large number of holes 29 which, in conjunction with the edge structure of the disk 3, also lead to an inhomogeneous edge area of the disk 3. There is a slightly frustoconical design of the disc 3, as can be seen in FIG. 7. In the area of the base of this truncated cone shape, the edge area forms a circumferential cutting edge 30 with which any chips are removed or sheared off from the end face of the respective work wheel during the deburring process.

According to the fourth embodiment illustrated in FIGS. 8 and 9, a disc-shaped deburring tool 3 is provided with ribs 31 which extend in the form of spokes towards the edge and between which grooves 32 extend.

The rib or groove structure corresponds to a trapezoidal shape. Here too, this rib / groove structure creates an inhomogeneous edge region of the disk 3, which counteracts the build-up of magnetism during the working process. The rib / groove structure is on the upper and bottom of the disc 3 is formed. The top edge of the disk 3 is provided with the circumferential cutting edge 30.

The deburring tool 3 illustrated in FIG. 10 according to the fifth embodiment is composed of two different materials. The cutting edge 33 is formed by a ring 34 made of magnetic steel. The ring 34 itself is fixed to a disk-shaped cutter support body 35 made of non-magnetic material. Both the cutting support body 35 and the ring 34 complement one another to form a truncated cone, the cutting edge 33 being at the level of the base of the truncated cone. The cutter support body 35 is assigned to the axis 36. Because of this configuration, the magnetic flux is also inhibited by the non-magnetic cutter support body.

According to the sixth embodiment according to FIG. 11, the disk 3 consists of different materials. For the cutting edge 33, a conically shaped ring 37 is used, which is pressed onto a correspondingly designed edge of the disk-shaped cutting body 35. In this version there is approximately a T-shaped cross section of the ring 37. The T-bar 38, which runs parallel to the cutting edge 33, contains through holes 39 for clamping screws 40 which engage in the cutting support body 35 or threaded bores 41 there, in order to be able to assign the ring 37 to the cutting support body 35.

In this embodiment, there is a circumferential cutting edge 33 which projects beyond the underside of the cutter support body 35. A milling cut could also be provided there. This configuration makes it possible to replace the ring 37 designed as a cutting element. The deburring tool 3 sits on the axis 36 and can be taken along by friction or by a drive. The seventh embodiment shown in FIG. 12 also has a blade support body 35 made of non-magnetic material. The cutter support body 35 is provided on the underside with a recess 42. A ring plate 43 forming the circumferential cutting edge 33 is supported on the bottom and on the outer edge thereof. It is held in its position by a clamping ring 44. The ring plate 43 is fixed in place by means of these penetrating clamping screws 40, which engage in threaded bores 41 of the cutter support body 35. The ring plate 43 corresponds approximately to the structure of a plate spring. This version also has interchangeability of the ring plate 43. This configuration also counteracts the build-up of magnetism when machining work wheels.

The deburring tool 3 illustrated in FIGS. 13 and 14, which relates to the eighth embodiment, is likewise designed in the form of a disk and has a multiplicity of individual cutting edges 46 which, according to this configuration, lie in radial recesses 47 of the cutting support body 48. Non-magnetic material is therefore also used for the latter. In the exemplary embodiment, the radial cutouts 47 accommodate the individual cutting edges 46 designed as indexable inserts. After wear of the respective

Cutting edge 33 can turn the triangle-shaped cutter support body the not yet used cutting edge into the functional position.

The ninth embodiment shown in FIG. 15 is similar to the eighth embodiment. Alternatively, the individual cutting edges 46 now lie in recesses 49 of the cutting support body 48 which are aligned in secant fashion. According to the tenth embodiment according to FIGS. 16 to 18, a cutting support body 48 made of non-magnetic material is also provided. In this version, a multiplicity of individual cutting edges 50 affect a common inner circle K. On the circumference, the cutting support body 48 forms pockets 51 in a corresponding angular distribution, into which the individual cutting edges 50 are inserted to achieve an alignment which diverges towards the cutting edge 53 and are fixed by means of clamping screws 52. The individual cutting edges 50 form tangentially directed cutting edges 53, which are assigned bevels 54 in the corner region. The latter are used to avoid bumping when a single cutting edge is used. In this version too, the structure of the deburring disc 3 counteracts the creation of a magnetic flux during processing.

According to the eleventh embodiment according to FIG. 19, a disk-shaped deburring tool 3 is also used. This consists of tool steel. It is frusto-conical in shape with the cutting edges facing the base. 19 there are three U-shaped cutting edges 55, 56, 57 which are concentric with the axis of rotation and which are at the same height. It is possible to arrange the peripheral cutting edges 55, 56, 57 in sectors on the circumference. The deburring tool 3 can be used with and without a drive. A combination of the deburring tool as a filing disc and a disc with a circumferential cutting edge may be possible.

The twelfth embodiment of the deburring disc 3 is shown in FIG. 20. The deburring tool 3 shown there is similar to that according to FIG. 19. In deviation, the peripheral cutting edges 55 ', 56', 57 'are now at different levels. In detail, such a design is made that the cutting edge height increases from the edge to the center of the disk. The deburring tool 3 illustrated in detail in FIG. 21 consists of tool steel and is designed in the form of a milling disk. A plurality of radially extending cutting edges 58 are provided there. A depth limiter 59 is preferably arranged between each two cutting edges 58 that are adjacent to one another. The same can be created, for example, in that the tooth lying between two adjacent cutting edges 58 is made to spring back against the cutting edges 58 by grinding. This results in blunt depth limits 59 without cutting action. This should originate exclusively from the cutting edges 58 themselves.

This configuration also counteracts the build-up of magnetism. In addition, the fact that the deburring process does not penetrate or get caught too deeply with the work wheel takes place due to the depth limits 59.

22 shows the fourteenth embodiment of the deburring tool 3. The latter is designed in the manner of a filing wheel with cutting edges 60 arranged on the underside of an annular surface. The cutting edges 60, each running tangentially to the inner ring circle 61, are crossed by secant channels 62. These extend at least to the bottom of the cutting teeth forming the cutting edges. Chip transport grooves are formed through the channels 62. The latter therefore fulfill a double function: on the one hand, they have the task of counteracting the build-up of a magnetic field and, on the other hand, they serve as grooves for transporting the sheared steel chips, so that they act in a similar way to grinding disks.

The transport grooves or channels 62 can take different angles to one another and to the disk. The fifteenth embodiment of the deburring tool 3 illustrated in FIGS. 23 and 24 has a frustoconical shape. The cutting edge 63 located on the base and running in the circumferential direction has a plurality of adjoining radial niches 64. Adjacent radial niches 64 meet in an edge line 65 corresponding to the shape of the truncated cone, which each form a corner 66 with the cutting edge 63. So this is the area that has the greatest radial distance from axis 36. 23 and 24, the radial niches 64 are uniformly shaped grooves. The deburring tool 3 designed in this way thus works with an interrupted cut and accordingly counteracts the build-up of magnetism. This deburring tool is then less sensitive to residual burr from hobbing, since a cutting movement in the circumferential direction is generated due to the serrated edge.

A modification of this fifteenth embodiment of the deburring tool 3 is shown in FIG. 25. This differs in that asymmetrically shaped radial niches 64 'are used. The edge lines 65 accordingly form teeth in a certain respect with the adjacent throat areas.

The deburring tool 3 preferably consists of a non-magnetic material. In particular, it can consist of ceramic. A deburring disc is then made from a ceramic material.

The invention further relates to a method and a device for deburring the tooth flanks of gearwheels, in particular for removing the burrs produced by machining the tooth flanks, the burrs being formed into the toothing by means of a first tool engaging, toothed folding wheel by radial pressure in the tooth gaps on the gear end face and sheared there by means of a second tool in the form of a deburring wheel.

In a deburring device of the type in question, there is provided a toothed folding wheel that is rotatably mounted parallel to the rotationally driven gear and radially deliverable on this. By engaging the teeth of the folding wheel in the tooth gaps and by radial pressure on the gear or on the tooth flanks of the gear, burrs there are flipped over to the face of the gear. In addition, the deburring device has a radially adjustable deburring wheel, which is also rotatably arranged parallel to the gear wheel. The deburring wheel can be driven in rotation. The rotary drive can also be carried out by frictionally following the gearwheel. The cutting edge located on the deburring wheel is used to shear off the secondary burr that projects beyond the face of the gear wheel. The very small secondary burrs, however, have a tendency to adhere as chips, particularly to the gear wheel or the folding wheel. To remove these chips there, the device must be rinsed with liquid during processing. This requires the workpieces to be cleaned after removal from the device. The deburring wheel must also be rinsed with liquid. Due to the rubbing of the cutting edge on the face of the gear wheel, the deburring wheel is magnetized during machining. As a result, steel shavings adhere to the deburring wheel and must be removed there, also with a rinsing liquid. However, the use of such rinsing liquids leads to the disadvantage that they have to be disposed of or reprocessed at great expense.

The invention is therefore based on the object of improving the generic method or the generic device in terms of production technology. The object is achieved by the invention reproduced in the claims, claim 23 initially and essentially based on the fact that the sheared ridges are removed without a liquid detergent by the chips being removed by an air flow generated in particular by compressed air or negative pressure. Accordingly, the generic device is further developed, which contains an air flow generating means for liquid-free chip removal.

As a result of such an embodiment, a method and a device are specified which permit the economical deburring of the tooth flanks of gear wheels. A liquid flushing medium can no longer be used. The chips adhering to the tools are now only removed by mechanical means. These means which generate an air flow can remove the chips at the point of origin, namely in the working area of the folding tool and / or the deburring tool. The air flow is adapted to the direction of rotation of the tools, i.e. the folding wheel and deburring wheel. The chips can be removed from the workpiece or the deburring wheel by a compressed air jet. For this purpose, a compressed air nozzle can be directed into the gusset between the work wheel and the deburring wheel, the air flow of the nozzle taking place in the direction of rotation of the two wheels. If a compressed air nozzle is used in combination with a suction nozzle, the compressed air flow emerging from the compressed air nozzle is guided in such a way that a part of the compressed air flow is sucked off together with the chips from the suction nozzle. In a further development of the invention, a second compressed air nozzle is provided, which is directed tangentially to the folding wheel. This compressed air nozzle tangentially sweeping the folding wheel with its compressed air jet is permanently assigned to an adjustable feed arm. In order to increase the effectiveness of the method or the device, the deburring disc can be gnetisierungeinrichtung be demagnetized. This can be arranged diametrically opposite the working area of the deburring wheel. In particular, the demagnetization takes place by means of an alternating electromagnetic field. Because of this, the tendency of the chips to adhere to the deburring wheel is eliminated, so that the effectiveness of the air flow is increased. Then, according to the invention, a compressed air nozzle, which is directed obliquely to the axis of the disc-shaped deburring tool and / or folding tool, can be provided, the compressed air jet of which partially sweeps over the outer edge region of the tool. The outer edge area is primarily the zone to which the chips adhere more strongly. The compressed air jet also takes effect there. There is also the possibility of providing a compressed air nozzle arrangement with a plurality of outlet nozzles arranged in the space between two disk-shaped tools which are parallel to one another and assigned to the same axis. This also ensures that sheared off chips are removed from the tools by the compressed air jet. A space-saving, effective design is achieved in that the compressed air nozzle arrangement is fed through the hub of the tool. In a further variant of the invention, a stationary air baffle arrangement is provided which forms an air flow guide chamber through which the edge regions of the tool or tools rotate. In detail, a Y-shaped air flow guide in the air flow guide chamber proves advantageous. It is possible to design the airflow routing in such a way that the air entry takes place in the Y-web. However, the air currents can also enter the diverging Y-legs. Furthermore, there is the possibility of providing a stationary shield surrounding a section of the tool equipped with deflection exit openings or its holder. In this regard, it is possible to assign the shield to the hub. This also fulfills another function by representing the storage of the tool. A further possibility of air guidance is realized by an air guiding section rotating with the tool, which directs the air jet supplied by a stationary compressed air nozzle onto the edge region of the tool. This also ensures that the air flow is directed through the edge of the tool itself. In order to largely remove chips from the tooth gaps in the case of folding wheels, the course of the compressed air nozzles points in the direction of a tooth gap of the bending tool. In the case of deburring wheels, on the other hand, the air flow emerges in the cutting area of the deburring wheel. Finally, in the case of a pair of tools, formed by two deburring wheels arranged on one axis, it is advantageous that the air flow exits on both sides of the cutting edges.

Referring to Figures 1-4, several embodiments of this invention are explained below with reference to the drawings. Show it

According to the embodiment shown in FIGS. 1 to 3, a liquid-free chip removal takes place. The means shown there are a suction device 6, 7, 9, compressed air nozzles 10, 11 and a demagnetizing device 15. However, each of these individual means for liquid-free chip removal can also be used individually or in any combination with another be realized. In addition, the measure can be provided to brush off the chips.

In detail, the device has a work wheel designed as a gear 1, the tooth flanks of which have been reworked. The gear wheel itself is driven in rotation about an axis of rotation 18. For example. the tooth flanks have been reworked by folding. When bending, burrs have arisen which are to be removed with the device.

For this purpose, the folding wheel designated with the reference number 2 is fed to the work wheel 1 in the radial direction. The folding wheel 2 sits on a feed arm 12 which can be pivoted about an axis of rotation (not shown) in the direction of the double arrow. In the exemplary embodiment, two folding wheels 2 lie in parallel to one another in order to deburr each of the two tooth flank end regions. There, the bevel gears 2 engage with their toothings 20 in the toothings 19 of the work wheel 1. As a result of the radial pressure, burrs present there are pressed axially outward over the wide surface of the work wheel 1. The secondary burrs thus created are removed with a deburring wheel 3.

The deburring wheel 3 is also seated on a feed arm 14 which can be pivoted about an axis (not shown) in the direction of the double arrow. The deburring wheel 3 is dragged by the gear 1 by friction. In combination with the deburring wheel 3 and a smoothing wheel (not shown), a tooth engagement between the deburring wheel 3 and the gear wheel 1 can be provided. In the exemplary embodiment, two deburring wheels 3 lying parallel to one another are provided, which shear off the secondary burrs formed with their cutting edges 22 resting on the gear wheel end faces. The reference number 8 denotes the end of a suction line. A replaceable head piece 9 is flanged to the end of the suction line 8. This head piece 9 forms fork-shaped suction nozzles 6, 7 which protrude into the respective gusset between the gear 1 and the two tool wheels 2, 3. The mouth of the suction nozzles 6, 7 is located directly on the processing area 4 between the folding wheel 2 and the gear wheel 1 or the working area 5 of the deburring wheel 3 on the gear wheel 1. Instead of as shown, the suction nozzle 6 could be made longer than the suction nozzle 7, so that the suction nozzle 6 points into the opposite gusset and thus against the direction of rotation. If necessary, the suction nozzle 6 could also be omitted. The shavings sheared by the deburring wheel 3 from the end face of the gear 1 are sucked off by the suction nozzle 7. The suction nozzle 7 or the suction nozzle 6 can be designed such that it sucks off the two working areas lying one above the other in FIG.

The deburring wheel 3 rotates in the area of the working area 5 in the suction direction of the suction nozzle 7. The deburring wheel 3 also rotates in the direction of the blowing direction of a compressed air nozzle 10, which permanently blows into the gusset between the work wheel 1 and the deburring wheel 3. The compressed air nozzle 10 is accordingly in the region of the gusset which is arranged opposite the gusset of the suction nozzle 7.

While the compressed air nozzle 10 is operated continuously and is adjustable to the device with regard to differently sized work wheel diameters, a compressed air nozzle 11 is only actuated at intervals. The pressure- Air jet that escapes from the compressed air nozzle 11 is directed tangentially in the direction of rotation to the toothing 20 of the folding wheel 2. This compressed air nozzle 11 is assigned to the feed arm 12 of the folding wheel 2. This can be done by means of a tab 13.

The reference number 15 denotes a demagnetizing device. This demagnetizing device 15 is seated on the feed arm 14 of the deburring wheel 3. As can be seen in particular from FIG. 3, the demagnetizing device 15 forms two slots 17 through which the edge regions of the two deburring wheels 3 arranged parallel to one another dip. The edge areas of the deburring wheels 3 are immersed by an alternating electromagnetic field, so that the deburring wheel 3 is demagnetized. Any chips adhering to the deburring wheel 3 then lose their adhesion to the deburring wheel 3 and can be blown off using compressed air.

The deburring wheel 3 preferably dips contactlessly through the slot 17. However, mechanical removal of the chips could also be provided here.

In the embodiment shown in FIG. 4, the deburring wheel 3 is formed in two parts. It has a core made of a non-magnetic material, for example aluminum. A steel ring, which forms the cutting edge 22, is applied to the core. To reduce the magnetization of the ring, it has radial slots 23 and openings in the form of holes 24.

The operation of the device is as follows:

To load the device with a work wheel 1, the two tool wheels, the folding wheel 2 and the deburring wheel 3, are turned in the radial direction to the work piece axis 18 moved apart. This is done by pivoting the feed arms 12, 14. If the work wheel 1 is brought into position, the tool wheels 2, 3 are fed radially until the toothing 20 of the folding wheel 2 engages in the toothing 19 of the work wheel 1. Burrs in the toothing 19 are expressed by a radial pressure of the folding wheel 2 on the work wheel 1. Secondary burrs arise over the respective end face of the work wheel 1. These are sheared off by the deburring wheel 3, which is dragged along with it. This is done by the cutting edge 22 which is acted upon by force in the axial direction on the wide surface of the gear 1. The entrainment can also be carried out by means of a driving toothing 25 of the deburring wheel 3 which engages in the toothing 19 of the work wheel 1. Such meshing would be necessary when using a smoothing wheel.

In order to remove the swarf resulting from the burr removal, a local vacuum is generated in the area of the suction nozzles 6, 7. The air flowing into the suction nozzles 6, 7 contains chips which can subsequently be extracted from the suction air. The compressed air nozzle 10, which is directed into the gusset between the work wheel 1 and the deburring wheel 3, serves to support the chip transport in the direction of the suction nozzle 7.

The deburring wheel 3 is demagnetized by means of the demagnetizing device 15. This prevents chips from sticking to the deburring wheel 3.

In the third embodiment according to FIG. 5, two deburring wheels 27 are arranged in a parallel position to one another on a common axis 26. The cutting edges 22 are directed towards each other. Seen in detail, each deburring wheel 27 has a frustoconical shape. Compressed air nozzles 28 are arranged obliquely to the axis 26 of the disc-shaped deburring wheels 27, one compressed air nozzle 28 each on the truncated cone surface of the deburring burr wheel points in the direction of the cutting edge 22. In this regard, there are external compressed air nozzles 28, by means of which the compressed air is guided from the outside in the direction of the cutting edge 22 of the tool and there removes the chips located after the burrs have been sheared off. The air flow is sufficient to remove the chips from the magnetized tool. The laxative effect is supported by a previous demagnetization of the tool.

The fourth embodiment illustrated in FIG. 6 largely corresponds to the third embodiment. Instead of the deburring wheels 27, bevel wheels 29 arranged as tools on an axis 26 'are now used. The compressed air nozzles 28 which brush the outer edge region of the tools, here the folding wheels 29, are adapted to the course of the tooth gaps 30 and are freed of chips by the compressed air jet when the tools 29 circulate.

7, relating to the fifth embodiment, two deburring wheels 27 are provided in parallel to one another to form a pair of tools. In the intermediate space 31 there is a compressed air nozzle arrangement 32. This has an inlet pipe 33, to which an outward directed radial pipe 34 is connected. This forked in two compressed air nozzles 35. The emerging compressed air stream swept the cutting edges 22 of the deburring wheels 27.

The sixth embodiment according to FIG. 8 is similar to the fifth embodiment in FIG. 7. Folding wheels 29 are now used with respect to the tool. In the intermediate space 31, the compressed air nozzle arrangement 32 is provided, the compressed air nozzles 35 pointing in the direction of the tooth gaps 30 of the folding wheels 29, so that the tooth gaps 30 are freed of any adhering chips from the inside. According to the seventh embodiment in FIG. 9, two deburring wheels 27 are also arranged on a common axis 26 and rotate with it. A stationary air baffle plate arrangement 36 is assigned to the edge region of the deburring wheels 27. Specifically, this has two baffles 37, which are arranged parallel to the conical lateral surfaces of the deburring disks 27 and which open out into a discharge nozzle 38 by means of bends. Parallel to the baffle plates 37, counter baffle plates 39 are assigned to the deburring wheels 27, which in conjunction with the corresponding regions of the baffle plates 37 form inlet connections 40. A shielding plate 41 runs concentrically to the axis 26 on the edge side of the deburring wheels 27, so that the compressed air introduced into the inlet connection 40 sweeps over the cutting edge area of the deburring wheels 27. The compressed air, possibly containing chips, then leaves the air baffle arrangement 36 through the outlet connection 38. It can be seen that in this version a Y-shaped air flow guide is formed in the air flow guide chamber.

The eighth embodiment according to FIG. 10 shows two folding wheels 29 which are arranged at a parallel distance from one another and are arranged on a common axis of rotation 26 '. These are also disc-shaped and form toothing 30 with tooth gaps at the edge. A stationary air baffle arrangement 42 is also present in this version. The latter has an angular gusset 43, the tip of which lies at the level of the center of the intermediate space between the folding wheels 29. The individual gusset walls are adapted to the shape of the truncated cone-shaped outer surface of the folding wheels 29 and are arranged at a short distance from them. In addition, the air baffle arrangement 42 forms air baffles 44 which lie beyond the outer end face of the folding wheels and which form outflow nozzles 45. The guide walls 44 are aligned with short guide walls 46 of the intermediate space 31 '. There the guide walls 46 continue into an inlet connection 47. In contrast to the seventh embodiment, in this eighth embodiment there is a single air inlet connection 47 which opens into two air outlet connections 45. There is therefore a Y-shaped air flow guide in the air flow guide chamber, the air flow running through the tooth gaps 30 of the folding wheels in order in this way to remove any chips located in the edge region of the folding wheels 29 in the direction of the arrow in FIG. 10.

The ninth embodiment is illustrated in FIG. On a rotating hub 48, two bevel gears 29 are connected with the hub 48, which are non-rotatably connected, which are each frustoconical and form tooth gaps 30 on the edge, which mesh with the tooth gaps of the associated work wheel and produce the secondary burrs there. A shield 49 arranged between the folding wheels 29 is used to support the hub 48. In the exemplary embodiment shown, this is stationary. The hub 48 is equipped with a central air inflow channel 50 in the form of a blind hole. A plurality of radial channels 51, which are arranged in the same circumferential distribution and which lie at the level of the center of the intermediate space between the folding disks 29, open into the lower end thereof. The shield 49 forming the bearing is equipped with a relatively short radial channel 52 which merges into two deflection outlet openings 53 which diverge in the outward direction. These deflection outlet openings 53 each face the tooth gaps 30 in such a way that they can each blow into the tooth gaps 30 that are aligned with them, in order to blow out any adhering chips by compressed air. When the hub 48 and thus the folding wheels 29 rotate, the radial channels 51 arranged in the same circumferential distribution successively come into alignment with the radial channel 52 of the shield 49 or the bearing for the hub, so that the compressed air escapes in a pulsed manner. An age native could look so that the shield 49 rotates. The compressed air could reach the tooth gaps of the bending wheels 29 through a plurality of radial ducts arranged circumferentially distributed with associated deflection outlet openings.

While the air flow path through the hub to the outside takes place in the embodiment according to FIG. 11, there is a stationary compressed air inlet nozzle 54 according to the tenth embodiment according to FIG. 12, from which the air jet is directed over the edge region of the tool in question — deburring wheel 27 , In the exemplary embodiment, two deburring wheels 27 are also arranged coaxially one behind the other on a common hub 48. The compressed air inlet nozzles 54 are located parallel to the axis of rotation. At a small distance in front of the inner end of the compressed air inlet nozzles 54, air guide sections 55 end, which extend in flange form from the hub 48 and which consequently rotate with the tool, that is to say the deburring wheels 27. The two deburring wheels 27 are urged towards one another by compression springs 56. They step against a middle ring 57. This determines the size of the space between the facing end faces of the deburring wheels 27. The air guide sections 55 cause a meandering course with respect to the air flow in the direction of the edge of the tool or deburring wheel 27. This sweeps over the edge-side cutting area of the deburring wheels 27, so that chips adhering there are reliably removed.

Instead of the deburring wheels 27, folding wheels 29 could also be placed on the hub 48. Then the course of the compressed air nozzle, ie the continuation of the compressed air inlet nozzles 54, points in the direction of the tooth gaps 30 of the folding wheels 29, so that any chips that may be present there are also blown out. Alternatively, in the embodiment according to FIG. 12, the air guide sections 55 could be the wall of a Z-shaped throughflow opening. The flange region lying radially outward from the air guide sections 55 is then formed in one piece with the hub 48 and accordingly rotates with it. A plurality of Z-shaped throughflow openings are provided which, when the hub 48 or the deburring wheels 27 are rotated, come into alignment with the compressed air inlet nozzles 54 one after the other, as a result of which the cutting area is swept by pulsating compressed air blasts.

13, depicting the eleventh embodiment, sits on the axis 26

Deburring wheel 27. Inside the same is an air guide section 58 on the edge. The latter is essentially angular. The short angle leg of the same opens into the end face of the deburring wheel 27 opposite the cutting edge 22. There is a stationary compressed air nozzle 59 which is fed with compressed air in the direction of the arrow. The air jet is directed onto the edge region of the tool 27 by the air guide section 58. This looks like the air jet is directed through the edge 60 of the tool itself and exits there. A branch 61 located in front of the edge 60 directs an air jet obliquely downward, so that the air flow emerges on both sides of the cutting edge 22. This effect is further optimized by the fact that the air guide section 58 continues into a triple fork, the outlet openings 58 'of which open at the edge of the tool, that is to say on the truncated cone lateral surface there.

According to the twelfth embodiment according to FIG. 15, an edging wheel 29 is used instead of the deburring wheel 27. Within the same are located according to the number of tooth gaps 30 in the same circumferential distribution arranged air guide sections 58, each opening into a tooth gap 30. Then a stationary compressed air nozzle 59 is also arranged, which when the folding wheel 29 communicates in succession with the air guide sections 58. Intermittently, the tooth gaps 30 are successively freed of chips by compressed air.

The invention further relates to a method and a device for deburring the tooth flanks of gearwheels, in particular for removing the burrs produced by machining the tooth flanks, the burrs using a first tool in the form of a toothed folding wheel engaging in the toothing by radial pressure in the tooth gaps are turned over to the face of the gear wheel and are sheared off there by means of a second tool in the form of a deburring wheel.

A deburring device, as it is the starting point of the invention, has a toothed folding wheel which is rotatably mounted parallel to the rotationally driven gear wheel and which can be fed radially to this. By engaging the teeth of the degree of bending in the tooth gaps and by radial pressure on the gear or on the tooth flanks of the gear, burrs there are flipped over to the face of the gear. In addition, the deburring device has a radially adjustable deburring wheel, which is also rotatably arranged parallel to the gear wheel. The deburring wheel can be driven in rotation. The rotary drive can be carried out by frictionally running with the gear. The cutting edge located on the deburring wheel is used to shear off the secondary burr that projects beyond the face of the gear wheel. The very small secondary burrs have a tendency to adhere as chips, particularly to the gearwheel or the folding wheel. In order to remove these chips there, the device must be rinsed with liquid during processing. This requires the workpieces to be cleaned after removal from the device. The deburring wheel must also be rinsed with liquid. Due to the rubbing of the cutting edge on the face of the gear wheel, the deburring wheel becomes machining magnetized. As a result, steel shavings adhere to the deburring wheel and must be removed there, also with a rinsing liquid. The use of such rinsing liquids has the disadvantage that they have to be disposed of or reprocessed in a complex manner.

The invention is therefore based on the object of improving the generic method or the generic device in terms of production technology.

The object is achieved by the invention as set out in the claims, claim 46 initially and essentially based on the fact that the sheared burrs are removed without a liquid detergent and the chips adhering to the tools are removed mechanically. Accordingly, the device of the generic type is further developed, which contains movable means for removing chips that have bristles.

As a result of such an embodiment, a method and a device are specified which permit the economical deburring of the tooth flanks of gear wheels. A liquid flushing medium no longer has to be used. The chips adhering to the tools are now only removed by mechanical means. In particular, the chips can be removed by brushing. The latter move relative to the tools, the chips adhering to these being brought with certainty from the attachment to the tools. The relative movement of the bristles to the tools can be achieved in various ways. In particular, an advantageous embodiment consists in that the bristles are assigned to at least one rotating brush roller. The corresponding brushing effect can be varied by delivering the same to the tool. In this way, all will surely adhere to the tool. de Chips are removed in the area covered by the brush roller. It is then provided according to the invention that the axis of rotation of the brush roller is oriented perpendicular, inclined or parallel to the tool axis of rotation. Another advantageous feature of the invention is characterized by tools arranged in pairs, a pair of tools being radially brushed by the bristles of a single brush roller. This configuration is particularly suitable for removing the chips from the folding wheels. The bristles can dip through the gaps in the teeth of the folding wheels. In detail, this means that the brush roller axis runs approximately in the middle between the two tools of a tool pair and the

Tools are designed as folding wheels, the bristles passing through the tooth gaps of the rotating tools. This opens up the possibility of using the brush roller synchronously during the deburring process. When brushing the deburring wheels arranged on a common axis, such an embodiment is characterized in that the bristles of the brush roller fan out in the axial direction towards the brush edge, the edge length of the fanned brush roller being greater than the distance between the two tools of a pair of tools. In order nevertheless to allow the bristles to gently run into the space between the two tools of a pair of tools, guide plates which are assigned to one another in a funnel shape are provided in order to bring the bristle fan with a reduced edge length between the tools. In detail, there is such a structure that the guide plates have an approximately quarter-circular plan and the outlet side lies approximately on the line connecting the axes of the tool pair and the brush roller. For the purpose of varying the brushing effect, it is possible according to the invention that the brush rollers can additionally be moved linearly by motor. This means that there is an axial displacement of the brush roller overlapping the rotary movement. In this way, all shaved shavings can be safely removed from the tools. Referring to Figures 1-4, six embodiments of this invention are explained below with reference to the drawings. Show it:

According to the embodiment shown in FIGS. 1 to 3, a liquid-free chip removal takes place. The means shown there are a suction device 6, 7, 9, compressed air nozzles 10, 11 and a demagnetizing device 15. However, each of these individual means for liquid-free chip removal can also be implemented individually or in any combination with another. In addition, the measure can be provided to brush off the chips.

For this purpose, the folding wheel designated with the reference number 2 is fed to the work wheel 1 in the radial direction. The folding wheel 2 sits on a feed arm 12 which can be pivoted about an axis of rotation (not shown) in the direction of the double arrow. In the exemplary embodiment, two folding wheels 2 lie in parallel to one another in order to deburr each of the two tooth flank end regions. There, the bevel gears 2 engage with their toothings 20 in the toothings 19 of the work wheel 1. As a result of the radial pressure, burrs present there are pressed axially outward over the wide surface of the work wheel 1. The secondary burrs thus created are removed with a deburring wheel 3. The deburring wheel 3 is also seated on a feed arm 14 which can be pivoted about an axis (not shown) in the direction of the double arrow. By means of a tooth engagement or by friction, the deburring wheel 3 is dragged along by the gear wheel 1. In the exemplary embodiment, two deburring wheels 3 lying parallel to one another are provided, which shear off the secondary burrs formed with their cutting edges 22 resting on the gear wheel end faces.

The reference number 8 denotes the end of a suction line. A replaceable head piece 9 is flanged to the end of the suction line 8. This head piece 9 forms fork-shaped suction nozzles 6, 7 which protrude into the respective gusset between the gear 1 and the two tool wheels 2, 3. The mouth of the suction nozzles 6, 7 is located directly on the processing area 4 between the folding wheel 2 and the gear wheel 1 or the working area 5 of the deburring wheel 3 on the gear wheel 1. Instead of being shown, the suction nozzle 6 could be made longer than the suction nozzle 7, so that the suction nozzle 6 points in the opposite gusset and thus against the direction of rotation. The shavings sheared by the deburring wheel 3 from the end face of the gear 1 are sucked off by the suction nozzle 7. The suction nozzle 7 or the suction nozzle 6 can be designed such that it sucks off the two working areas lying one above the other in FIG.

The deburring wheel 3 rotates in the area of the working area 5 in the suction direction of the suction nozzle 7. The deburring wheel 3 also rotates in the direction of the blowing direction of a compressed air nozzle 10 which is permanently in the gusset between the work wheel 1 and Deburring wheel 3 blows. The blowing nozzle 10 is accordingly in the region of the gusset which is arranged opposite the gusset of the suction nozzle 7.

While the blowing nozzle 10 is operated permanently and is assigned to the device in an adjustable manner with regard to different work wheel diameters, a blowing nozzle 11 is only actuated at intervals. The compressed air jet, which escapes from the blowing nozzle 11, is directed tangentially in the direction of rotation onto the toothing 20 of the folding wheel 2. This blowing nozzle 11 is assigned to the feed arm 12 of the folding wheel 2. This can be done by means of a tab 13.

In the embodiment shown in FIG. 4, the deburring wheel 3 is formed in two parts. It has a core made of a non-magnetic material, for example aluminum. A steel ring, which forms the cutting edge 22, is applied to the core. To reduce the magnetic Sation of the ring has this radial slots 23 and openings in the form of holes 24th

The operation of the device is as follows: To load the device with a work wheel 1, the two tool wheels, the folding wheel 2 and the deburring wheel 3, are moved apart in the radial direction to the workpiece axis 18. This is done by pivoting the feed arms 12, 14. If the work wheel 1 is brought into position, the tool wheels 2, 3 are fed radially until the toothing 20 of the folding wheel 2 engages in the toothing 19 of the work wheel 1. Burrs in the toothing 19 are expressed by a radial pressure of the folding wheel 2 on the work wheel 1. Secondary burrs arise over the respective end face of the work wheel 1. These are sheared off by the deburring wheel 3 carried along by the rotation between the deburring wheel 3 and the work wheel 1. This is done by the cutting edge 22 which is acted upon by force in the axial direction on the wide surface of the gear 1. The entrainment can also be carried out by driving teeth 25 of the deburring wheel 3 which engage in the teeth 19 of the work wheel 1. Such meshing would be necessary when using a smoothing wheel.

In order to remove the swarf resulting from the burr removal, a local vacuum is generated in the area of the suction nozzles 6, 7. The air flowing into the suction nozzles 6, 7 contains chips which can subsequently be extracted from the suction air. The blowing nozzle 10, which is directed into the gusset between the work wheel 1 and the deburring wheel 3, serves to support the chip transport in the direction of the suction nozzle 7. Instead of the means for liquid-free chip removal used in the previous exemplary embodiments, brushes can be used as in the following exemplary embodiments or can be provided in combination with the aforementioned means. The deburring wheel 3 is demagnetized by means of the demagnetizing device 15. This prevents chips from sticking to the deburring wheel 3.

5, relating to the third embodiment, two tools arranged in pairs are provided on the tool axis of rotation 26. These are designed as deburring wheels 3 and form the opposite cutting edges 22 on the edge. Essentially, the deburring wheels 3 are frustoconical in cross-section such that the base edges face each other. A brush roller 27 is assigned to each deburring wheel 3. Its axes 28 are aligned at right angles to the tool axis of rotation 26. Also possible is an inclined position of the axes 28 or, in plan view, an angular adjustment to the circumferential circle of the deburring discs 3. The axes 28 extend approximately at the center of the deburring wheels 3. The direction of rotation of the brush rollers 27 is indicated by the direction of the arrow. In the active position of the brush rollers 27, their bristles 29 paint over the truncated cone outer surface of the deburring wheels 3 and remove any chips that may be adhering there. The sweeping area of the brush rollers 27 extends to the cutting edges 22. The directions of rotation of the brush rollers are directed in opposite directions so that the bristles 29 of each brush roller 27 move linearly along the truncated cone surface. Furthermore, an alternative could look such that a plurality of brush rollers which are offset in the circumferential direction from one another become effective on the deburring wheels.

It is not shown that the axes 28 of the brush rollers 27 can carry out a linear movement in the radial direction to the deburring wheels 3 in order, for example, to be able to also assign deburring wheels of different diameters. The distance must also be increased if the deburring wheels are changed. It is also not illustrated that the brush rollers are motorized in addition to their rotation in the direction of their axes 28 are linearly movable, so that a superimposed movement component takes place when the chips are brushed off the deburring wheels 3.

According to the fourth embodiment according to FIG. 6, two tools in the form of folding wheels 2 are arranged on a common tool axis of rotation 30. Both folding wheels 2 accordingly form a pair of tools, the tool wheels 2 being arranged at a distance from one another. In this fourth version, a single brush roller 31 is provided, the bristles 29 of which radially coat both tools, that is to say the folding wheels 2. In the exemplary embodiment, the brush roller axis 32 is oriented perpendicular to the axis of rotation 30 of the tool pair and runs centrally between the two tools 2. However, it can be adapted to the helix angle in the case of helical teeth on the work wheel, for which purpose a corresponding inclination adjustment of the brush roller axis 32 is provided is. When the brush roller 31 is in brush insert, the bristles 29 pass through the tooth gaps of the toothing 20 of the folding wheels 2. The direction of rotation of the brush roller 31 is also indicated with the direction of the arrow. Then the brush roller 31 is aligned so that its bristles 29 brush the bottom of the tooth gaps of the toothing 20. Here, too, there is the possibility of radial displacement of the brush roller 31 in order to always bring it into engagement optimally or to allow the brush roller 31 to be switched off. The bristles 29 pass through the tooth gaps when the brush roller 31 is driven in rotation and the folding wheels 2 are rotating.

According to the fifth embodiment according to FIGS. 7 to 11, the axis of rotation 33 of the brush roller 34 runs parallel to the tool axis of rotation 26. The tools in the form of deburring wheels 3 are arranged on top of one another in this manner. Their structure corresponds to the deburring wheels according to the third embodiment according to FIG. 5. Specifically, the brush roller 34 has a brush core 35, from which the bristles 29 extend outward, in such a way that the bristles 29 fan out in the axial direction to the brush edge. In cross section, this means that the brush roller 34 has a frustoconical cross section in the bristle area, starting from the brush core 35 to the edge of the brush. The present edge length a is greater than the distance b between the two tools 3 of a pair of tools, in this case between the deburring wheels 3.

As illustrated in FIG. 7, the brush roller 34 and the deburring wheels 3 overlap. In order to be able to reach the space between the deburring wheels 3 with the bristles without hindrance, an inlet funnel 36 is provided. This has two guide plates 37 which are arranged at a distance from one another. Their task is to reduce the size of the bristle fan

Bring edge length a 'between the two deburring wheels 3. The guide plates 37, which are arranged to cover one another, have an approximately quarter-circular plan. In particular, their outer edge widens slightly towards the inlet side E in a spiral. A transverse wall 38, which connects the two guide plates 37 to one another, is adapted to the outer course of the guide plates 37.

As illustrated in FIG. 7, the outlet side A lies approximately on the connecting line of the axes 26, 33 of the tool pair and the brush roller 34. The inlet side E of the inlet funnel 36 is correspondingly larger. There, the baffles 37 are at a distance from one another which is greater than the edge length a, see FIG. 8. As soon as the bristles leave the outlet side A of the inlet funnel 36 when the brush roller 34 rotates, they fan out and coat the areas facing them Deburring wheels 3 and remove the chips from there. In this version, too, it is provided that the inlet funnel 36 converges with the brush roller axis 33. can be put. A highly wear-resistant material is used for the bristles 29.

According to the sixth embodiment according to FIGS. 12 and 13, the deburring wheel 3 is designed as a filing wheel. The cutting surface in question is in the form of an annular surface on the broad side of the deburring wheel 3. In detail, the cutting edges are formed by approximately radially aligned teeth. A different alignment of the filing teeth is also possible. The deburring wheel 3 works together with a brush disk 40. The bristles 41 are located on the flat surface facing the filing wheel, which brush over the teeth and remove any chips that may be adhering there. The axis 42 of the deburring wheel 3 and the axis 43 of the brush disk 40 run parallel to one another in the illustrated embodiment. If necessary, an inclination adjustment of the brush disk axis 43 would be possible. Furthermore, the brush disk 40 is delivered and turned off.

The invention further relates to a method and a device for deburring the tooth flanks of gear wheels, in particular for removing the burrs produced by machining the tooth flanks, the burrs using a first tool in the form of a toothed folding wheel engaging in the toothing by radial pressure in the tooth gaps are transferred to the face of the gear and are sheared off there using a second tool in the form of a deburring wheel.

In deburring devices of this type, a toothed folding wheel is provided which is rotatably mounted parallel to the rotationally driven gearwheel and can be advanced radially onto the gearwheel. Due to the radial pressure on the gear wheel or on the tooth flanks of the same, so-called secondary burrs are flipped onto the face of the gear wheel. Using the second tool in the form of a Deburring wheel, which, like the folding wheel, can be rotated parallel to the gear wheel, the secondary burrs in question are sheared off by means of a cutting edge of the deburring wheel. These relatively small secondary burrs have a tendency to stick to the gearwheel or to the tools that process it. In order to remove these chips there, the device must be rinsed with liquid during processing. The workpieces or gearwheels must be cleaned after removal from the device. Furthermore, due to the frictional contact of the cutting edge of the deburring wheel on the front face of the gearwheel, the deburring wheel is magnetized during processing. As a result, steel shavings adhere to the deburring wheel and must be removed there. In the prior art, this is also done using rinsing liquid. The latter leads to the disadvantage that it has to be disposed of or reprocessed at great expense.

This object is achieved first and foremost in a method with the features of claim 58, the focus being on the fact that the sheared-off burrs are supported by magnetic force without a liquid detergent being removed.

Accordingly, no liquid detergent needs to be used to remove the sheared burrs, which makes deburring the tooth flanks more economical. There is also no need to dispose of the rinsing liquid or to prepare it. The sheared burrs are now removed with magnetic force. The removal of the sheared burrs can be influenced by appropriate dimensioning of the magnetic field. In detail, the procedure according to the invention is such that the chips are ne airflow brought into the working area of the tools can be transported into a magnetic field. The air flow can be generated by suction and / or compressed air nozzles. The suction or pressure direction of the air flow is preferably adapted to the direction of rotation of the gear and tools. The sheared burrs, entrained by the air flow, enter the magnetic field, so that both the gears and tools are freed from sheared chips during the process. It is further provided according to the invention that the deburring wheel, which is magnetized due to its edge rubbing on the workpiece, is demagnetized at a point remote from the work area by means of a magnet. Accordingly, the deburring wheel is additionally demagnetized, so that the tendency for the chips to adhere to the deburring wheel is eliminated. This ensures that all of the chips are transported into the responsible magnetic field by the air flow.

The device for deburring the tooth flanks of gear wheels is characterized by means for liquid-free chip removal, which means have at least one magnet. As a result, the construction of the device can be made simple in connection with a reduction in the manufacturing costs of the device. The means for liquid-free chip removal generate an air flow acting in the working area of the tools for transporting the chips into the force field of the magnet. In addition, the removal effect of the sheared-off chips is supported by a demagnetizing device having a magnet for the tools, in particular for the deburring wheel. It is possible to arrange this demagnetizing device in a diametrically opposed position to the working area of the deburring wheel. The demagnetization device can preferably be permanently assigned to a feed arm in order to be able to bring it into the optimal position relative to the deburring wheel. When changing the workpiece, the demagnetization direction are moved together with the assigned tool wheel. In a further development of the invention, it is provided that the demagnetization device forms slots through which the edge regions of two deburring wheels arranged parallel to one another pass without contact. In this way, an optimal demagnetization of the deburring wheels sitting parallel to each other on an axis takes place. The demagnetization device is designed in such a way that it generates an alternating electromagnetic field. The influence of the magnetic field on the tool can be varied in that the magnet is driven linearly in the radial direction to the tool and / or is rotated about an axis. It is also conceivable to overlay these movements by vibrations. For example. the magnet can sit between two tools that are arranged on the same axis. There is also the possibility of providing a magnetic field running parallel to the axis of the tool through the edge of the tool. To remove chips adhering to the magnet, a scraper assigned to the magnet can be provided. It is also possible to assign wiping means to the tool in order to remove the swarf from the tool that builds up in the magnetic field. As an alternative, agents that generate vibrations can act on the deburring wheel to demagnetize the deburring wheel by mechanical means. These can preferably be clappers or pneumatic cylinders.

The exemplary embodiment shown in FIGS. 1-3 contains several means for liquid-free chip removal included in the invention, i.e. the suction device 6, 7, 9, the compressed air nozzles 10, 11 and the demagnetizing device 15. However, each of these individual means for liquid-free chip removal can can also be implemented individually or in any combination with another.

The work wheel 1, which is a gear wheel whose tooth flanks have been reworked, is driven in rotation about an axis of rotation 18. The tooth flanks have been reworked, for example, by folding. When bending, burrs have arisen which are to be removed with the device. For this purpose, the folding wheel designated with the reference number 2 is fed to the work wheel 1 in the radial direction. The folding wheel 2 sits on a feed arm 12 which can be pivoted about an axis of rotation (not shown) in the direction of the double arrow. In the exemplary embodiment, two folding wheels 2 lie in parallel to one another in order to deburr each of the two tooth flank end regions. There, the bevel gears 2 engage with their toothings 20 in the toothings 19 of the work wheel 1. As a result of the radial pressure, burrs present there are pressed axially outward over the end face of the work wheel 1. The secondary burrs thus created are removed with a deburring wheel 3. The deburring wheel 3 is also seated on a feed arm 14 which can be pivoted about an axis (not shown) in the direction of the double arrow. The deburring wheel 3 is dragged by the gear wheel 1 by means of a tooth engagement or frictional engagement. In the exemplary embodiment, two deburring wheels 3 lying parallel to one another are provided, which shear off the secondary burrs formed with their cutting edges 22 resting on the gear wheel end faces.

The reference number 8 denotes the end of a suction line. An interchangeable head piece 9 is flanged to the end of the suction line 8. This head piece 9 forms fork-shaped suction nozzles 6, 7 which protrude into the respective gusset between the gear 1 and the two tool wheels 2, 3. The mouth of the suction nozzles 6, 7 is located directly on the processing area 4 between the folding wheel 2 and the gear wheel 1 or the working area 5 of the deburring wheel 3 on the gear wheel 1. Instead of as shown, the suction nozzle 6 could be elongated compared to the suction nozzle 7 be so that the suction nozzle 6 points in the opposite gusset and thus against the direction of rotation. The shavings sheared by the deburring wheel 3 from the end face of the gear 1 are sucked off by the suction nozzle 7. The suction nozzle 7 or the suction nozzle 6 can be designed such that it sucks off the two working areas lying one above the other in FIG.

The deburring wheel 3 rotates in the area of the working area 5 in the suction direction of the suction nozzle 7. The deburring wheel 3 also rotates in the direction of the blowing direction a compressed air nozzle 10, which permanently blows into the gusset between work wheel 1 and deburring wheel 3. The blowing nozzle 10 is accordingly in the region of the gusset which is arranged opposite the gusset of the suction nozzle 7.

The reference number 15 denotes a demagnetizing device. This demagnetizing device 15 is seated on the feed arm 14 of the deburring wheel 3. As can be seen in particular in FIG. 3, the demagnetizing device 15 forms two slots 17 through which the edge regions of the two deburring wheels 3 arranged parallel to one another dip. The edge areas of the deburring wheels 3 are immersed by an alternating electromagnetic field, so that the deburring wheel 3 is demagnetized. Any chips adhering to the deburring wheel 3 then lose their adhesion to the deburring wheel 3 and can be blown off using compressed air.

In the embodiment shown in FIG. 4, the deburring wheel 3 is formed in two parts. It has a core made of a non-magnetic material, for example aluminum. A ring made of magnetizable steel is applied to the core and forms the cutting edge 22. For the tion of the magnetization of the ring or interruption of the magnetic flux, this has radial slots 23 and openings in the form of holes 24. The outward-pointing open radial slots 23 lead to an interruption in the cutting edge.

The operation of the device is as follows:

To load the device with a work wheel 1, the two tool wheels, the folding wheel 2 and the deburring wheel 3, are moved apart in the radial direction to the workpiece axis 18. This is done by pivoting the feed arms 12, 14. If the work wheel 1 is brought into position, the tool wheels 2, 3 are fed radially until the toothing 20 of the folding wheel 2 engages in the toothing 19 of the work wheel 1. The deburring wheel 3 is rotatably driven by frictional engagement with the work wheel 1 or by engagement of the driving toothing 25 of the deburring wheel in the toothing 19 of the work wheel 1. Burrs in the toothing 19 are expressed by exerting a radial pressure of the folding wheel 2 on the work wheel 1. Secondary burrs arise over the respective end face of the work wheel 1. These are sheared off by the deburring wheel 3. This is done by the cutting edge 22 which is acted upon in the axial direction on the wide surface of the gear 1.

In order to remove the swarf resulting from the burr removal, a local vacuum is generated in the area of the suction nozzles 6, 7. The air flowing into the suction nozzles 6, 7 contains chips which can subsequently be extracted from the suction air. The blowing nozzle 10, which is directed into the gusset between the work wheel 1 and the deburring wheel 3, serves to support the chip transport in the direction of the suction nozzle 7.

The deburring wheel 3 is demagnetized by means of the demagnetizing device 15. This prevents chips from sticking to the deburring wheel 3. As can be seen from the above, an air flow is generated by the suction nozzles 6, 7 and blowing nozzles 10, 11, which removes any adhering chips. It is now possible to remove sheared burrs supported by magnetic force. The chips can be transported into a magnetic field by means of the air flow, for which purpose magnets (not shown) which generate magnetic fields are positioned at a corresponding point.

According to the third embodiment, shown in FIGS. 5 and 6, two deburring wheels 3 are arranged on a common axis in parallel with one another, the cutting edges 22 in question facing each other. In the edge region between the deburring wheels 3, a magnet 26 designed as an electric or permanent magnet can be driven in the radial direction. A magnetic field is generated by this magnet 26, so that with the magnet 26 inserted between the deburring wheels 3, see FIG. 6, chips adhering to the deburring wheels 3 are removed. The corresponding linear movement in the direction of the double arrow indicated in FIG. 5 can also be superimposed by vibrations. It is possible to demagnetize the tools by means of such a magnet during processing or during the rest periods of the tools. The chips can be removed from the tool or from the deburring wheels 3 by means of a stronger magnetic field. The distance between the magnet 26 and the deburring wheels 3 can be varied by means of the machine control. With this magnet too, an alternating electromagnetic field can be generated to demagnetize the tool.

7 and 8, which illustrate the fourth embodiment, show a magnet 26 which, in addition to its back and forth movement, can be rotated about an axis 27 arranged parallel to the tool axis of rotation. According to this fourth embodiment, the magnet 26 acts with two on one common axis of rotation arranged folding wheels 2 together. According to FIG. 7, the magnet 26 is located outside the intermediate space between the two folding wheels 2. In FIG. 8, the magnet 26 is inserted between the folding wheels 2 in the edge region thereof and, by means of magnetic force, removes shaved chips from chips adhering to the folding wheels 2.

The fifth embodiment illustrated in FIGS. 9 and 10 includes a demagnetizing device 28 in the form of a magnet. This is designed as a mirror-image E. In the radial direction, see double arrow in FIG. 9, the magnet 28 can be switched on and off. The magnet 28 is oriented such that the outer legs protruding from it run outside the deburring wheels 3, while the middle leg dips into the space between the deburring wheels 3. It would be possible to also assign such a magnet 28 to the folding wheels 2.

11 and 12, relating to the sixth embodiment, two parallel folding wheels 2, which sit on a common axis and are aligned parallel to one another, are assigned a magnet 29. This is composed of three plates arranged one above the other in parallel, the two outside plates overlapping the two folding wheels 2 on the outside, while the middle plate enters the space between the folding wheels. The three plates are connected by an axis 30. The magnet 29 can be displaced radially to the folding wheels 2 in the double arrow direction. In addition, rotation of the magnet 29 in the direction of the arrow about its axis 30 is possible. The plates of the magnet 29 are polarized accordingly. This configuration also makes it possible to demagnetize or to attract chips adhering to the folding wheels 2. According to the seventh embodiment in FIG. 13, a magnet 31 extends in front of the space between two deburring wheels 3. This magnet is U-shaped in such a way that the poles point in the direction of the deburring wheels 3. The chips adhering to these can be attracted by means of the magnet 31, which can optionally be displaced radially to the deburring wheels 3. The chips collecting at the poles stand up and can be removed by means of a scraper 32 running parallel to the axis of rotation of the deburring wheels 3. Other directions of travel of the scraper are possible. It is essential that the chips adhering to the magnet 31 are stripped off. Alternatively, wiping means can also be assigned to the tool itself, in order to remove the chips from the tool that build up in the magnetic field.

According to the eighth embodiment in FIG. 14, a rotatable magnet 33 is provided between two folding wheels 2 arranged parallel to one another. FIG. 14 largely corresponds to FIG. 8. In addition, the eighth embodiment includes a U-shaped scraper 34, which overlaps the area of the magnet 33 diametrically opposite the folding wheels 2. The axis of rotation of this magnet 33 runs parallel to the axis of rotation of the folding wheels 2.

The ninth embodiment illustrated in FIG. 15 shows a deburring wheel 3 in cooperation with a demagnetizing device 35. This has a fork piece 36 made of magnetizable iron with an approximately U-shaped cross section. The fork slot 37 is positively adapted while maintaining a gap in the cross-sectional contour of the edge of the deburring wheel 3. To generate an electromagnetic alternating field, by means of which the deburring wheel 3 is demagnetized, an electromagnet 38 arranged on the fork web of the fork piece 36 is used. This configuration makes it possible for the as a magnet serving fork piece 36 can be designed as an interchangeable part with regard to differently shaped deburring wheels.

It is possible to combine the previous embodiments with one another to achieve further variants. In principle, the wipers can be designed to be fixed or movable.
