Abstract
The utility model discloses a kind of sun gear gasket, belong to a kind of parts on hub reduction gear drive axle.It includes mainly shim body, and the shim body is equipped with oil-way, and oil-way is set to the side at shim body center；The shim body is equipped with more than two anti-rotation convex bodys；The shim body is annular gasket；The shim body surface carries out Nitrizing Treatment.The utility model is simple in structure, easy to use, avoids abrasion of the gasket to end cap, improves the service life of hub reduction gear, while improving the service life of gear oil.The utility model is mainly used for the drive axle of hub reduction gear.
Description
Technical field
The utility model belongs to a kind of parts on hub reduction gear drive axle, specifically, more particularly to it is a kind of too
Sun wheel gasket.
Background technology
Hub reduction gear is afterbody deceleration torsion increasing device in car transmissions, can be met using hub reduction gear
Resultant gear ratio under the same conditions, makes the load of the components such as speed changer, transmission shaft, main reducing gear, differential mechanism, semiaxis reduce, ruler
Very little the advantages that becoming smaller and drive axle is made to obtain the larger road clearance, is widely used in load truck, motorbus, cross-country
Automobile and some other large-scale work mine car.
Currently, in hub reduction gear drive axle, the position that sun gear is contacted with end cap is generally using the round sun
Take turns gasket, in practical work process, round sun gear gasket can together be rotated with sun gear, cause end cap abrasion and
The pollution of gear oil.
Invention content
The purpose of the utility model is to overcome drawbacks described above, provide a kind of sun gear gasket, simple in structure, user
Just, abrasion of the gasket to end cap is avoided, the service life of hub reduction gear is improved, while it is all to improve using for gear oil
Phase.
The sun gear gasket, including shim body, the shim body are equipped with oil-way, oil-way setting
Side in shim body center.
Further, the shim body is equipped with more than two anti-rotation convex bodys.
Further, the shim body is annular gasket.
Further, the shim body surface carries out Nitrizing Treatment.
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model adds oil-way in shim body, the gear oil for making driving member splash during the motion
It is stockpiled in into oil-way, increases the lubrication between sun gear and shim body, reduce the gold that driving member galling generates
Belong to bits, improves the cleannes of transmission cavity；
2, shim body and end cap are fixed by two symmetrically arranged anti-rotation convex bodys, avoid gasket by the utility model
Ontology is rotated with sun gear, has prevented abrasion of the shim body to end cap, improves the service life of hub reduction gear；
32, shim body surface carry out Nitrizing Treatment, to improve the wear-resisting property on shim body surface, make sun gear with
When the relative rotation of shim body, big abrasion not will produce, reduce the pollution of gear oil, improve gear oil uses week
Phase.
Description of the drawings
Fig. 1 is the front view of the utility model；
Fig. 2 is the left view of the utility model；
Fig. 3 is the use state reference chart of the utility model.
In figure, 1, shim body；2, oil-way；3, anti-rotation convex body；4, end cap；5, sun gear；6, hub reduction gear is total
At.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, sun gear gasket includes shim body 1, and the shim body 1 is equipped with oil-way 2,
Oil-way 2 is set to the side at 1 center of shim body；Shim body 1 is equipped with more than two anti-rotation convex bodys 3；Gasket sheet
Body 1 is annular gasket.
For the utility model when making, 1 surface of shim body carries out Nitrizing Treatment, improves its wear-resisting property, Nitrizing Treatment
For the prior art.
As shown in Fig. 2, when the utility model is used, shim body 1 be mounted on hub reduction gear assembly 6 end cap 4 on,
Shim body 1 is fixed together by anti-rotation convex body 3 and end cap 4, to prevent shim body 1 from being rotated with sun gear 5, is avoided
Abrasion of the shim body 1 to end cap 4；During the work time, gear oil is splashed to enter in oil-way 2 by driving member and be stockpiled,
Increase the lubrication between sun gear 5 and shim body 1, reduces the metal fillings that driving member galling generates, improve transmission cavity
Cleannes and hub reduction gear assembly 6 life and reliability.
