Abstract
The utility model relates to a plane gasket, its characterized in that includes the gasket body, the gasket body is ring shape and two terminal surfaces are the plane, be equipped with on at least one terminal surface of two terminal surfaces of gasket body and be convex oil groove, the oil groove intercommunication the interior circumference wall and the external circumferential wall of gasket body. The utility model has the advantages of simple and reasonable structure, set up convex oil groove on two terminal surfaces, improve the lubricated situation of plane gasket, improve the plane gasket reliability, increase of service life, processing is convenient, and the processing cost is low to reducing the operation friction between plane gasket and the peripheral part, improving part life, reduce the fault is rateed, reduces the maintenance cost.
Description
Technical field
The utility model relates to a kind of pad, especially relates to a kind of flat pad.
Background technique
Flat pad is the pad that a kind of both ends of the surface are plane, be widely used in all kinds of machinery, be mainly used in bearing pressure, adjustment distance etc., but at some in particular cases, flat pad also needs to bear the wearing and tearing that relative movement brings, such as, for the flat pad in automobile differential, its planetary pinion, planet pin are arranged in the housing of automobile differential together, owing to having relative movement between flat pad and planetary pinion and housing, have anti abrasive requirement to flat pad.Automobile is in long-term actual use, because operating mode is severe, lubrication state constantly changes, by the impact of the factor such as lubricating condition is not good, and the both ends of the surface of flat pad are all smooth planes, cause the wearing and tearing of flat pad and part due to insufficient lubrication between the both ends of the surface of flat pad and planetary pinion and differential casing, the reliability of flat pad and working life also can be affected, make differential mechanism rate of fault raise simultaneously, keep in repair continually, increase maintenance expenses, also affect the reliability of differential mechanism.
Model utility content
The applicant, for above-mentioned problem, is studied improvement, provides a kind of flat pad, simple and reasonable, improves flat pad lubrication state, improves flat pad reliability, increases the service life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of flat pad, comprise shim body, described shim body is ring and two end faces are plane, and at least one end face of two end faces of described shim body is provided with the oil groove in circular arc, and described oil groove is communicated with inner peripheral wall and the outer circle wall of described shim body.
Further:
Described oil groove is made up of two sections of symmetrically arranged circular arc oil grooves.
Described two sections of symmetrically arranged circular arc oil grooves are arranged on circumferentially same.
Two end faces of described shim body are respectively equipped with two sections of symmetrically arranged circular arc oil grooves, and the oil groove on two end faces to be arranged on two eccentric directions circumferentially contrary.
The cross section of described oil groove is circular arc.
Technique effect of the present utility model is:
Disclosed in the utility model, a kind of flat pad, simple and reasonable, two end faces arranges circular arc oil groove, improves flat pad lubrication state, improves flat pad reliability, increase the service life; Easy to process, processing cost is low, and reduces the operation friction between flat pad and peripheral component, improves part working life, reduces rate of fault, reduces maintenance expenses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A place sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises shim body 1, shim body 1 is in ring and two end faces are plane, the upper-end surface of shim body 1 is provided with the oil groove 2 in circular arc, the lower end surface of shim body 1 is provided with the oil groove 3 in circular arc, the cross section of oil groove 2, oil groove 3 is in being circular arc, and the cross section of oil groove 2, oil groove 3 also can be other shape, can conveniently determining according to processing.Oil groove 2, oil groove 3 are all communicated with inner peripheral wall 4 and the outer circle wall 5 of shim body 1, such oil groove 2, oil groove 3 all can have flowing to or flowing out of lubricant oil on inner peripheral wall 4 and outer circle wall 5 direction, like this, strengthen the mobility of lubricant oil, the lubrication effect for pad two end faces is better.In the present embodiment, oil groove 2, oil groove 3 are made up of two sections of symmetrically arranged circular arc oil grooves respectively, two sections of symmetrically arranged circular arc oil grooves of oil groove 2 are arranged on circumferentially same, two sections of symmetrically arranged circular arc oil grooves of oil groove 3 are arranged on circumferentially same, and oil groove 2 on two end faces and oil groove 3 are arranged on two eccentric directions contrary circumferentially (as Fig. 1).Oil groove 2, oil groove 3 are made up of same circular arc oil groove circumferentially respectively, and processing is more convenient like this, can complete by turnery processing is disposable, save processing cost, and improve work efficiency, and need not use Cutter Body Processing with Machining Center, cost is high, and efficiency is low.
When reality uses, because two end faces of flat pad are all well lubricated, improve flat pad lubrication state, reduce the operation friction between flat pad and peripheral component, improve flat pad reliability, extend the working life of flat pad, improve peripheral component working life, reduce rate of fault, reduce maintenance expenses.
Claims (5)
