Abstract

The utility model discloses a bearing seal ring, including skeleton, offset plate, first seal lip, second seal lip and little triangle rubber, the inboard looks adhesion of skeleton has the offset plate, the radial extension of inner wall of offset plate is provided with first seal lip and second seal lip, still be equipped with the wainscot on the offset plate and bend the area, the wainscot is located the outer top in the area of bending, be equipped with three little triangle rubber on the outside of skeleton bottom, little triangle rubber cooperatees with the offset plate, be equipped with a plurality of bump on the internal surface of skeleton head, the utility model discloses can make difficult leakage of grease of bearing, outside debris and dust are difficult to invade insidely, improve the life of bearing greatly, little triangle rubber and retaining ring cooperation on the skeleton, greatly increased seals the effect, be equipped with the bump on the skeleton head internal surface, can contact with the bearing better, further increased the effect sealed and fastening.

Description

A kind of bearing sealed ring

[technical field]

The utility model relates to the technical field of Bearing fittings, particularly a kind of technical field of bearing sealed ring.

[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 sealed ring, 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 sealed ring, comprise skeleton, offset plate, the first sealing lip, the second sealing lip and little triangle rubber, the inner side phase adhesion of described skeleton has offset plate, the inwall of described offset plate is radial extended the first sealing lip and the second sealing lip, described offset plate is also provided with veneer and bending strip, described veneer is positioned at the outer top of bending strip, outside bottom described skeleton is provided with three little triangle rubber, described little triangle rubber matches with offset plate, and the internal surface of described skeleton head is provided with several salient points.

As preferably, the length of described first sealing lip is slightly less than the length of the second sealing lip, and the width of described first sealing lip is equal with the width of the second sealing lip.

As preferably, the flanging of described skeleton external diameter matches with bearing, and the little triangle rubber on described skeleton coordinates with back-up ring.

As preferably, the outer wall of described skeleton head 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 can make the grease of bearing not easily leak, outside foreign material and dust are difficult to invade inside, greatly improve the working life of bearing; Little triangle rubber on skeleton coordinates with back-up ring, greatly increases sealing effect; Skeleton head inner surface is provided with salient point, 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.

[accompanying drawing explanation]

Fig. 1 is the structural representation of a kind of bearing sealed ring of the utility model.

In figure: 1-skeleton, 2-offset plate, 3-first sealing lip, 4-second sealing lip, the little triangle rubber of 5-, 6-bending strip, 7-outer wall, 8-veneer, 9-salient point.

[embodiment]

Consult Fig. 1, a kind of bearing sealed ring of the utility model, comprise skeleton 1, offset plate 2, first sealing lip 3, second sealing lip 4 and little triangle rubber 5, the inner side phase adhesion of described skeleton 1 has offset plate 2, the inwall of described offset plate 2 is radial extended the first sealing lip 3 and the second sealing lip 4, described offset plate 2 is also provided with veneer 8 and bending strip 6, described veneer 8 is positioned at the outer top of bending strip 6, outside bottom described skeleton 1 is provided with three little triangle rubber 5, described little triangle rubber 5 matches with offset plate 2, the internal surface of described skeleton 1 head is provided with several salient points 9, the length of described first sealing lip 3 is slightly less than the length of the second sealing lip 4, the width of described first sealing lip 3 is equal with the width of the second sealing lip 4, the flanging of described skeleton 1 external diameter matches with bearing, little triangle rubber 5 on described skeleton 1 coordinates with back-up ring, the outer wall 7 of described skeleton 1 head is in outer little interior large toroidal surface structure, the material of described offset plate 2 is rubber.

Utility model works process:

A kind of bearing sealed ring of the utility model in the course of the work, the flanging of skeleton 1 external diameter and bearing drive fit, thin rubber under flanging and lasso fit tightly, offset plate 2 inwall is radial extended the first sealing lip 3 and the second sealing lip 4, first sealing lip 3 enters bearing for stoping environmental contaminants, second sealing lip 4 is for preventing grease in bearing excessive, guarantee that bearing is intact, little triangle rubber 5 on skeleton 1 closely cooperates with back-up ring, considerably increase the effect of sealing, salient point 9 and bearing contact with each other, guarantee to seal and fastening effect, the utility model can make the grease of bearing not easily leak, outside foreign material and dust are difficult to invade inside, greatly improve the working life of bearing, processing is simple, easily shaping, intensity is good, sealing effect is splendid.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
