Abstract
The utility model relates to a combined oil seal of a rear end cover, comprising an oil seal body and the rear end cover, wherein the oil seal body comprises a framework, a rubber body and a spring; the rubber body is provided with a main sealing lip and an auxiliary sealing lip; the rubber body is provided with a second auxiliary sealing lip; and the second auxiliary sealing lip is in buffering contact and connection with the limit part of the rear end cover. The combined oil seal has the advantages of being accurate in concentricity, convenient in installation and low in production cost.
Description
Technical field
The utility model relates to a kind of Sealing, especially relates to a kind of rear end cover combined type oil sealing.
Background technique
Present combined type oil seal structure, be to adopt two component separately to produce separately, after assembling by third party main engine factory again, reinstall in the cylinder body of motor, such two shortcomings of structural design existence: two component separate machined of the first are produced the difficult control of critical size precision, cannot say for sure to demonstrate,prove with the concentricity of bent axle; It two is that the rear end cover oil sealing chamber of the former factory supply of material does not have any limit stoper, and press-fiting of oil sealing be cannot say for sure to cause oil sealing and rear end cover oil sealing chamber to occur departing from by card easily, influences the safe application performance of motor.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems, and the rear end cover combined type that a kind of concentricity is accurate, easy for installation, cost of production is low oil sealing is provided.
The purpose of this utility model is achieved in that and comprises oil sealing body and rear end cover, and the oil sealing body comprises skeleton, rubber body and spring, and rubber body is provided with main lip of sealing and sealing pair lip; Rubber body is provided with the second sealing pair lip, and the second sealing pair lip is connected with the limited part buffering contact of rear end cover.
The utility model, rear end cover are provided with the rear end cover support that is connected with the skeleton interference fit of oil sealing body.
The beneficial effects of the utility model are:
1), original two component are controlled as a total member, so both guarantees the concentricity of oil sealing body and rear end cover, can control relevant dimensional accuracy again well;
2), increase a limiting and protecting device, can control, and when total member is packed bent axle into, also can play the certain protection effect the sealing pair lip of oil sealing to the effect that press-fits of oil sealing in the oil sealing chamber of rear end cover;
3), two parts are press-fited as a total member supply of material, both improve the efficiency of installing software of motor, saved cost of production again.
The utility model has the advantage that concentricity is accurate, easy for installation, cost of production is low.
Following embodiment is further described the utility model in conjunction with the accompanying drawings.

Fig. 4 is Fig. 1 embodiment's an oil sealing main body structure schematic representation.
Among the figure, 1, skeleton; 2, rubber body; 3, spring; 4, seal main lip; 5, sealing pair lip; 6, the second sealing pair lip; 7, rear end cover; 8, the limited part of rear end cover; 9, rear end cover support.
Embodiment
Referring to figs. 1 through Fig. 4, present embodiment is a kind of rear end cover combined type oil sealing, comprises oil sealing body and rear end cover 7, and the oil sealing body comprises skeleton 1, rubber body 2 and spring 3, and rubber body is provided with main lip 4 of sealing and sealing pair lip 5; Rubber body is provided with the second sealing pair lip, 6, the second sealing pair lips and is connected with the limited part 8 buffering contacts of rear end cover; Rear end cover is provided with the rear end cover support 9 that is connected with skeleton 1 interference fit of oil sealing body.
Use of the present utility model, referring to figs. 1 through Fig. 4, it is the sealing pair lip 5 and the second sealing pair lip 6 that the design of the oil sealing body of present embodiment has the sealing pair lip of two kinds of different structures; Sealing pair lip 5 mainly is to play dustproof and protection to running shaft, plays the effect that a guiding is proofreaied and correct when running shaft is installed; The second sealing pair lip 6 act on oil sealing body and rear end cover when press-fiting, can play the buffering decompression, be damaged to combining of oil sealing and support when preventing to press-fit simultaneously, also guaranteed the sealability that oil sealing body and rear end cover integrally combine.
Assembling of the present utility model, with reference to Fig. 2, Fig. 3, the oil sealing body that will expose skeleton forms rear end cover combined type oil sealing with rear end cover riveting dress, the termination of running shaft is inserted in the center hole of oil sealing body again.
The utility model further promotes the concentricity of oil sealing and rear end cover, and rear end cover installs limiting and protecting device additional, improves the Safety performance that motor uses, and improves installation efficiency simultaneously, reduces enterprise's cost of production.
