Abstract
The utility model discloses a spline type locking composite roll, comprising a roller core and a roll sleeve which are in spline fit, wherein at one end or two ends of the roll sleeve, the roll sleeve is axially locked and located by a mounting pad ring. The utility model aims to provide the composite roll which is simple in structure, excellent in stability, long in service life and high in working stability.
Description
Technical field
The utility model relates to the assembly roller technical field, relates in particular to a kind of employing spline assembly roller.
Background technology
At present, various alloy rollers have been widely used in the bar continuous rolling production line, and various syndetons also begin to appear in the alloy roller of different manufacturers production.Compare with original monoblock type roll, use combined type alloy roller structure can greatly reduce the roll cost, and can improve its service life.But the difference of various structures must be brought various practical effect, also knows from the situation of steel rolling mill's feedback, due to the bad accident of often bringing roll breakage of structural design.
The assembly roller structure, modal is that former monoblock type roll is decomposed into roller shell and two separate parts of roller core, then adopts various frame mode to link.Wherein roller shell adopts the abrasion-resistant stee that can satisfy the steel rolling needs, and roller core adopts the strong structural alloy steel of flexing resistance, thereby realizes the Optimum Matching of performance.
China Patent No. 02251138.5 discloses a kind of combining structure of assembly roller, its technical characterictic is to use between roller shell and roller core interference to be connected, frictional force transmitting torque by the over pressure generation, but due to the demand of alloy roller for wearability, its elastic-plastic strain district is lower, do not overcome the required pressure of moment of torsion so its pressure that produces by maximum interference often reaches it, cause in use roller shell and roller core generation skidding.
Summary of the invention
For above deficiency of the prior art, the purpose of this utility model is to provide a kind of simple in structure, good stability, long service life, assembly roller that job stability is high.
For achieving the above object, the technical solution of the utility model is:
A kind of spline roll that is locked comprises roller core and roller shell, it is characterized in that: roller core and roller shell spline fitted, the roller shell axial locking is located by gasket ring is installed in the one or both ends of roller shell.
Further, an end of described roller core has the roller core step, and interlude is spline segment, after roller core and roller shell spline fitted with roller core step uniform thickness.
Further, spline segment and the roller shell of described roller core are isometric, or the end face of the one or both ends of spline segment and roller shell, and described gasket ring is bolted to the spline segment of roller core and the end face of roller shell by pressure.
For further reinforcing, the outside of described pressure bolt and gasket ring has locking nut, and described locking nut is installed on roller core by screw thread.
Advantage of the present utility model and beneficial effect are as follows:
1, due to assembly roller only by roller core, roller shell, locking nut, simple in structure, easy to assembly, job stability is high, has reduced production cost;
2, be connected to spline joint due to roller shell and roller core, can transmit more high pulling torque, satisfy the user demand of different frame operating modes.
Description of drawings
Fig. 1 is the utility model spline assembly roller view;
Fig. 2 is that roll is along the cutaway view of A-A;
In figure: the 1-roller core; The 2-locking nut; 3-pressure bolt; The 4-gasket ring; The 5-roller shell; The 6-spline segment.
The specific embodiment
Providing a non-limiting embodiment below in conjunction with accompanying drawing is further elaborated the utility model.
Referring to the roll that is locked of the spline in Fig. 1, Fig. 2, comprise roller core 1 and roller shell 5, wherein: roller core 1 and roller shell 5 spline fitted, in the one or both ends of roller shell 5 by gasket ring 4 being installed with roller shell 5 axial lockings location.
In embodiment, an end of described roller core 1 has the roller core step, and interlude is spline segment 6, after roller core and roller shell spline fitted with roller core step uniform thickness.
Spline segment and the roller shell of described roller core are isometric, or the end face of the one or both ends of spline segment and roller shell.In the present embodiment, spline segment 6 is bolted to the spline segment of roller core and the end face of roller shell with the described gasket ring of end face of the one or both ends of roller shell by pressure.
Preferably, the spline segment of described roller core 1 and roller shell 5 are isometric, and described gasket ring 4 is fixed on the spline segment of roller core 1 and the end face of roller shell 5 by pressure bolt 3.
The outside of described pressure bolt 3 and gasket ring 4 has locking nut 2, and described locking nut 2 is installed on roller core 1 by screw thread, further to prevent the axial float of roller shell 5.
Operation principle:
As everyone knows, spline is best transmitting torque frame mode, yet it but can't guarantee on axial float.The stress of complexity when working in view of roll, certain versatility on the structure in conjunction with present domestic milling train, the utility model has been used spline transmitting torque principle, and the reverse screw bolt locking mechanism in auxiliary two ends has satisfied the work requirements of roll.During work, the moment of torsion of roller core transmission is passed to roller shell by spline, satisfies the steel rolling requirement, by regulating reverse bolt, prevents the axial float of roller shell simultaneously.This kind is simple for structure, has symmetry from structure simultaneously, more satisfies structure design principle, also more meets the steel rolling operating mode.
Referring to Fig. 1, roller core cylindrical and roller shell inner circle all are processed with the spline that is complementary, and during assembling, at first roller shell 5 are arranged on roller core, and an end aligns with the roller core step; Afterwards gasket ring 4 roller rest cover one sides are in place, as transition piece; Be threaded connection again and locking nut 2 be installed to roller core, after being in place, by the pressure on rotational lock nut 2, bolt 3 is held out against gasket ring 4, thereby reach the effect of axial restraint roller shell.
Embodiment given here is interpreted as only being used for explanation the utility model and is not used in restriction protection domain of the present utility model.After the content of having read record of the present utility model, the technical staff can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim limited range equally.
