The intermediate transmission shaft sealing mechanism disclosed by the utility model has the beneficial effects of simple structure, convenient installation and high reliability; a comparatively stretching amount of the transmission in the axial direction is permitted when the vehicle bumps, and a circumferential swinging of the bearing shaft by 5 degrees in the bearing base is permitted; and the sealing performance and transmission durability of the intermediate shaft are improved.
Description
Technical field
The utility model relates to a kind of intermediate transmission axial sealing mechanism.
Background technique
Along with the development of automotive industry, automobile more and more spread to the common people other, the Consumer has obvious subjective feeling requirement to the sealing of automobile, dustproof, noise reduction.Existing automobile middle transmission shaft sealing mechanism probably can be divided into two kinds: a kind of being mounted in the commutator, dust-proof cover by interference fit to the housing of commutator, and then fit together closely by the collar on the dust-proof cover and vehicle body, realize sealing; Another kind is mounted on the intermediate propeller shaft, fits by the rubber layer on the seal ring and intermediate propeller shaft, realizes sealing and dustproof.
The first sealing configuration is prone to the installation incomplete phenomena, causes dust-proof cover and vehicle body the slit to occur, the phenomenon that seeps water can occur when paddling; And require stricter to the fit dimension of collar and dust-proof cover, the hardness of dust-proof cover etc.
The second sealing configuration technique is complicated, and often meeting and rubber layer friction of intermediate propeller shaft rotation, easily causes rubber layer poorly sealed.
The model utility content
The purpose of this utility model provides a kind of intermediate transmission axial sealing mechanism, by the profile cooperation of multiple component and the application of ball bearing, has overcome above shortcomings in the prior art.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of intermediate transmission axial sealing mechanism, comprise bearing support, the bearing briquetting, ball bearing and supporting plastic ring, bearing support inside is provided with circular arc portion one, circular arc portion one top and bearing support joint are provided with concave station, the inner interference fit bearing of bearing support briquetting, bearing briquetting inside is provided with circular arc portion two, circular arc portion two is provided with platform with bearing briquetting end face joint, platform is close to concave station, the sphere interference fit ball bearing that circular arc portion one and circular arc portion two form, ball bearing inside is provided with needle bearing, on the ball bearing, lower limb is provided with the lip limit, and lip limit interference fit has the supporting plastic ring that runs through needle bearing.
The beneficial effects of the utility model are: this product structure is simple, easy for installation, and reliability is high; Allow transmission shaft at axial direction larger extending amount to be arranged when vehicle jolts, and transmission shaft can be done 5 ° circle swing in bearing support; Greatly improve the sealing of jack shaft and rotated wear resistance.
