Definitions
- the invention relates to a wave gear according to the preamble of the main claim.
- a wave gear - also known as a harmony drive or a ring belt gear - as a very strongly reducing, self-locking system with an output shaft that is coaxial with the drive shaft
- a rotatingly driven non-circular core a so-called well generator
- an inner wheel also known as a flexible band
- Tires are radially deformed all the way round, thereby pressing the outer circumferential surface locally and outward slightly against the hollow cylindrical inner circumferential surface of a slightly larger circumference of a ring gear that is stationary and serves as a dimensionally stable support ring.
- the inner wheel itself or a wheel tire rotatably mounted on it rotates non-positively via friction surfaces or positively via toothings in the support ring, the wheel or its tire rotating more slowly than the motor-driven drive core of the wave generator, depending on the circumferential difference between the support ring and the inner wheel.
- This rotational movement which is greatly slowed down in relation to the drive, is preferably transmitted via the external toothing of the inner wheel tire to the internal toothing of a further outer ring, which is concentric with the support ring but, in contrast to that, is arranged in a non-stationary but coaxially rotatable output ring, which is designed, for example, in the form of a pot or hood and with an output shaft mounted in the gearbox.
- the speed of rotation can be further reduced as a result of the different circumference (ie different number of teeth).
- the well generator is usually driven by a coaxial flanged high-speed small chip voltage DC motor, the rapid rotation of which is thus reduced to a much slower rotary motion corresponding to greater torque, which is used in many ways, for example as an actuating element for engine and climate management and for other functions in the motor vehicle that replace manual interventions.
- a non-circular wave generator (approximately triangular in axial cross section or preferably oval) drive core rotated concentrically in the hub of a radially deformable inner wheel, which can be a one-piece injection molded part with spoke-like, radially oriented tappets between the radially deformable inner wheel hub and the likewise radially deformable, externally toothed inner wheel tire of the hub radially deformed by the drive core and the tire have the effect that the external teeth, in accordance with their circumferential radial deformation, each have only a limited, circumferentially displacing arc piece with the coaxial, axially offset internal teeth of the support ring and the output ring engages.
- the present invention is based on the technical problem of specifying a compact, yet easily assembled and versatile structure for such a shaft gear which has already proven itself in practical use.
- the task is essentially solved in that the internal toothing of the support ring is no longer an integral part of the gearbox housing for an unproblematic, precisely producible wave gear, but instead is assembled on a housing base plate after separate production and then to be fastened separately by one Housing pot is overlapped.
- the pot accommodates the central output shaft of the hood-shaped output ring, while the base plate has no direct bearing function for rotating gear parts.
- reaction forces of the transmission are only absorbed by this base plate; therefore, they cannot impair the bearing function of the other housing part, which due to its fixation on the base plate also acts radially centering and axially guiding.
- the outside of the base plate can be ge on differently available drive motors can be designed geometrically different.
- the centering of the inner wheel does not take place directly over the base plate, but rather by means of the drive shaft which projects through it.
- Their direct engagement in the sleeve-shaped drive core also has the advantage of eliminating the drive-side mounting in the gearbox, because this bearing function is taken over on the drive side outside the gearbox. This enables direct installation in front of the drive without the interposition of a coupling element and thus results in an axially short design of a very strongly reducing gear motor.
- Fig.l the structure of the wave gear in an unassembled housing in an exploded view
- Fig.2 the fully assembled wave gear in view against the base plate of its housing
- Fig.3 two such wave gear in a cascadable arrangement.
- FIG. 1 of the drawing The exploded view sketched in FIG. 1 of the drawing, completely made of plastic injection molded parts and designed according to the invention, has a housing 11 with a circular disk-shaped base plate 12.
- a central through hole 13 serves for the engagement of the drive shaft 14 of a drive motor 15 in the transmission 10.
- the diameter of the hole 13 is larger than that of the shaft 14, so that no radial bearing function occurs here.
- the base plate 12 is provided with profiles such as incisions and / or holes for the positive engagement of complementary profiles in the end region 17 of a support ring 18 to be arranged fixed to the housing, with dimensionally stable internal teeth 19.
- the support ring 18 can be fixed in a rotationally rigid manner to the through hole 13 on the base plate 12, independently of a housing pot 20 that is later to be slipped over with radial play, on the end face positively or non-positively - for example by crimping or soldering or gluing.
- the support ring 18 is then axially and dial overlapped by the hood-shaped pot 20, which is also held on the end face on the base plate 12, with an inserted driven ring 27.
- the wall 21 of the pot 20 is distributed over the circumference with a few axially parallel spring hooks 22 for locking with the edge region 16 of the base plate 12 (see FIG. 2), approximately as sketched in the form of a tab-shaped opening towards the front of the pot and thus towards the base plate 12 cut-out spiral springs with angled free end faces for reaching behind the profiled edge area 16.
- the support ring 18, which is mounted separately on the base plate 12, has the special advantage, as already stated above, of a support ring integrated into the hollow cylindrical inner wall of the pot 20, the internal toothing 19 of which is more precisely circular manufacture and thereby achieve a low-loss, that is to say particularly low-noise transmission run.
- the opposite bottom 23 of the pot 20 represents the free end face of the housing 11 and thus also of the gear 10 and contains the only bearing point of this gear 10.
- the pot bottom 23 is a bearing plate with a sock-shaped reinforcement for forming a radial bearing 24 for a transmission output shaft 25 projecting coaxially to the motor drive shaft 14.
- This is torsionally rigid with a likewise cup-shaped or hood-shaped output ring 27 provided with dimensionally stable internal toothing 26. Its average diameter is roughly the same as that of the support ring 18 fixed to the housing axially in front of the base plate 12, so that the driven ring 27 is axially guided between that and the inner surface of the bottom 23 in the pot 20.
- the radial holding ring of the driven ring 27 takes place by means of its driven shaft 25 anchored in the hood base or integrally formed therewith in the housing bearing 24 and, if necessary, also in relation to the hollow cylindrical inner surface of the pot or housing wall 21.
- a radially deformable inner wheel 28 with external teeth 29 is arranged within the two coaxially held, axially adjacent rings 18-27 with their different numbers of teeth in accordance with the slightly different inner circumferences. This is axially longer than each of the two adjacent, dimensionally stable rings 18, 27 and therefore meshes simultaneously via the radially bulged arc piece with its two internal teeth 19, 26.
- the inner wheel 28 is preferably as long as the two rings 18-27 together and is thus guided axially between the base plate 12 and the hood base of the driven ring 27.
- a cross-sectionally non-circular, preferably oval sleeve-shaped drive core 30, which is rotated by a motor from outside the transmission 10.
- the inner wheel 28 and its central drive core 30 are not supported in the housing 11 of the transmission 10 and are therefore not centered in the rings 18, 27 of larger inner diameter.
- the radial alignment takes place, however, in that the base plate 12 is mounted centered with respect to the drive shaft 14 projecting through it and into the drive core 30, that is to say that the shaft 14 engages in the drive core 30 with the base plate 12 coaxially mounted on its end plate 32.
- This end shield 32 in turn represents the end closure of the housing of the drive motor 15.
- the engagement of the drive shaft 14 in the drive core 30 can be non-positive;
- a form fit is to be preferred, for example due to the cross-sectionally flattened cross-section of the shaft 14, as can be seen for the shafts 25/14 in FIG. 3.
- the base plate 12 can have a coaxial recess 31 (see FIG. 2) on the outside, that is to say in its free end face, into which a base 35 in the form of a truncated cone on the end plate 32 for the driving shaft 14 (in particular the drive motor) 15) engages axially.
- the assembly itself is expediently carried out by means of integrally formed or separate fastening elements such as short clamping screws 33 which are axially parallel through the base plate 12 and screwed into threaded bores 34 in the end shield 32. If not yet done, the support ring 18 can now be mounted on the base plate 12.
- the projecting through the base plate 12 free end of the drive shaft 14 is equipped with the drive core 30 and this with the inner wheel 28, whereupon the hood-shaped output ring 27 over the axially protruding from the support ring 18 part of the inner wheel 28 and finally the pot 20 until it locks the base plate 12 are placed over the output ring 27.
- the output shaft 25 of the gear 10 then protrudes through the housing bearing 24, whereby the wave gear 10 is already assembled ready for operation.
- the base 23 of the housing pot 20 serving as the gear-side bearing plate, like the bearing plate of the drive motor 15, is also equipped with fastening means such as threaded holes 34 for tensioning screws 33.
- Wave gear 10 with its base plate recess 31 instead of in front of a drive motor 15 in the same way also in front of another such wave gear 10 with its centering protruding bearing base 35 and the gear reduction thereby cascaded, as indicated in FIG. 3.
- the freely protruding shaft from the foremost pot base 23 of the foremost transmission 10 serves as an output shaft 25, while the others each serve as drive shafts 14.
- a wave gear 10 of such a cascade is then mounted with its base plate 12 in front of the pot base 23 of the preceding wave gear 10, the base 23 of which thereby acts as a bearing plate 32 for a drive shaft 14 which centers the inner wheel 28 in the housing 11 of the following gear stage.
- end shields 32 of drive motors 15 or of gearboxes 10 to be cascaded form themselves directly as the base plates for housings of the shaft gearboxes 10 connected here, whereby a separate assembly via the tensioning screws 33 or similar fastening elements can be omitted.
- an unproblematically producible and easily - also cascaded - mountable wave gear 10 results in that the support ring 18, which is manufactured separately from the housing 11, is mounted on the end on a housing base plate 12 in a rotationally rigid manner and by a housing which is also to be fastened to the base plate 12 thereafter.
- Pot 20 is overlapped, in the base 23 of which the output shaft 25 of the hood-shaped output ring 27, which is rotatable relative to the support ring 18, is mounted in a floating manner.
- the radially deformable inner wheel 28, which extends axially through the two radially dimensionally stable rings 18-27 with radial play, is not, however, mounted in the housing 11 itself, but rather via its wave generator drive core 30 on the under radial play through the base plate 12 coaxially into Housing 11 protruding drive shaft 14, in front of its bearing plate 32, the base plate 12 is rotatably mounted.
