Description
[technical field]
The utility model relates to the technical field of bearing seal, particularly a kind of technical field of bearing dustproof cover.
[background technique]
Along with the development of World Auto Industry grows, the status of automotive industry in development of world economy is more and more outstanding, and automotive industry produces huge effect and far-reaching influence to the development of World Economics and the progressive of society.Bearing is indispensable for automobile, and normally work is very important for it, and bearing seal can play the normal work of available protecting bearing.Bearing seal is the critical component that bearing runs well in rugged environment, and it plays protection bearing from erosion and pollution, and bearing can be worked in good clean lubrication environment.And the inside of bearing is due to a large amount of grease lubrication of needs, if sealing effect is bad, can grease be produced excessive, affect the running of bearing.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of bearing dustproof cover, and the grease of bearing can be made not easily to leak, outside foreign material and dust are difficult to invade inside, greatly improve the working life of bearing, and processing is simple, easily shaping, intensity is good, and sealing effect is splendid.
For achieving the above object, the utility model proposes a kind of bearing dustproof cover, comprise skeleton, offset plate, reentrant part and protrude into portion, the interior edge face outer rim of described skeleton has inside lug boss, described skeleton interior edge face inner edge has outside reentrant part, the interior drive fit socket of described skeleton arranges circular offset plate, the inwall of described offset plate is radial extended the first sealing lip, second sealing lip and the 3rd sealing lip, described first sealing lip, second sealing lip and the 3rd sealing lip are in the outside being axially in lug boss, the outer surface of described skeleton is provided with several anti-skidding salient points equally distributed.
As preferably, the width of described first sealing lip, the second sealing lip and the 3rd sealing lip is equal, and the length of described 3rd sealing lip is slightly larger than the length of the first sealing lip and the second sealing lip.
As preferably, the female portion is equipped with terraced steps, and described offset plate tightly fits in above-mentioned terraced steps.
As preferably, the outer wall of described lug boss is outer little interior large toroidal surface structure.
As preferably, the material of described offset plate is rubber.
The beneficial effects of the utility model: the utility model passes through flanging and the bearing drive fit of skeleton external diameter, and the thin rubber under flanging and lasso fit tightly, and prevent bearing grease from overflowing from overcoat; Outside the 3rd sealing lip near skeleton enters bearing for stoping environmental contaminants, and guarantee that bearing is intact, the first sealing lip of inner side and the second sealing lip are used for preventing grease in bearing excessive; Skeleton outer surface is provided with several anti-skidding salient points equally distributed, can better with bearing touch, further increase sealing and fastening effect; The utility model processing is simple, and easily shaping, intensity is good, and sealing effect is splendid.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
