A kind of Special bearing for carrier rollers of high leakproofness disclosed by the invention, including bearing inner race, bearing outer ring, one is arranged on the retainer between the bearing inner race and bearing outer ring and some balls being arranged between the bearing inner race and bearing outer ring and in the ball pocket of the retainer, also include a first seal being removably mounted in the end face outside of the bearing inner race, the first seal radially extends and the end face outside of the bearing outer ring is enveloped and is hardly formed between the first seal and the end face outside of the bearing outer ring and contacts.The Special bearing for carrier rollers of the present invention cancels traditional complicated high cost sealing, thorough seal is carried out to bearing end face outside using above-mentioned first seal, prevent that moisture and dust are also prevented from while grease from leaking enters the working face of bearing, it is ensured that bearing is normally run under various operating modes.

Description

A kind of Special bearing for carrier rollers of high sealing performance
Technical field
The present invention relates to technical field of bearings, more particularly to a kind of Special bearing for carrier rollers of high sealing performance.
Background technology
Traditional Special bearing for carrier rollers includes bearing inner race, bearing outer ring, is arranged between bearing inner race and bearing outer ring Retainer, in some ball pockets for being arranged on the retainer and positioned at the ball between bearing inner race and bearing outer ring and point The seal of both sides between bearing inner race and bearing outer ring is not arranged on.Special bearing for carrier rollers is mainly used in universal industrial city High speed, inner ring rotation and the application environment of field are difficult under contaminated etc. operating mode.However, traditional Special bearing for carrier rollers is deposited In following shortcoming：1st, the application of outer ring rotation is not suitable for, grease is easily revealed；2nd, need extra increase seal or skeleton close Envelope, adds the overall manufacturing cost of carrying roller；3rd, outside labyrinth or other seals add damping, reduce the fortune of bearing Line efficiency；If the 4, not using the further seals of outside, bearing is directly exposed under atmospheric environment, in addition existing seal Bearing face can not be protected, bearing steel gets rusty easily, influence the normal operation of bearing.
Therefore, applicant carried out beneficial exploration and trial, have found result of the above problems, it will be detailed below being situated between The technical scheme continued is produced under this background.
The content of the invention
The technical problems to be solved by the invention：It is special that a kind of carrying roller of high leakproofness is provided in view of the shortcomings of the prior art Use bearing.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of Special bearing for carrier rollers of high leakproofness, including bearing inner race, bearing outer ring, one it is arranged on the bearing inner race Retainer between bearing outer ring and some it are arranged between the bearing inner race and bearing outer ring and kept positioned at described Ball in the ball pocket of frame, it is characterised in that be also removably mounted on including one in the end face outside of the bearing inner race First seal, the first seal radially extends and envelopes the end face outside of the bearing outer ring and described first It is hardly formed and contacts between seal and the end face outside of the bearing outer ring.
In a preferred embodiment of the invention, in the first seal towards setting on the end face of the bearing inner race A ring shaped axial lip is equipped with, an annular lip, the first seal are formed with the end face outside of the bearing inner race Ring shaped axial lip be connected in the annular lip formed in the end face outside of the bearing inner race.
In a preferred embodiment of the invention, set on the inner side end between the bearing inner race and bearing outer ring It is equipped with second seal.
In a preferred embodiment of the invention, the retainer is made of engineering plastics.
In a preferred embodiment of the invention, the first seal is by skeleton and is coated on the skeleton Sealing ring is constituted, and the sealing ring is extruded injection molding process by high temperature and is made, and the sealing ring is by following material combination system Into by weight percentage：
As a result of technical scheme as above, the beneficial effects of the present invention are：
1st, Special bearing for carrier rollers of the invention cancels traditional complicated high cost sealing, using above-mentioned first seal pair Bearing end face outside carries out thorough seal, prevents that moisture and dust are also prevented from while grease from leaking enters the working face of bearing, Ensure that bearing is normally run under various operating modes；
2nd, contacted due to being hardly formed between first seal and the end face outside of bearing outer ring, the axle when carrying roller is run Bearing outer-ring rotates and bearing inner race is static, can efficiently reduce overall damping；
3rd, by adding hygroscopicity antistatic additive, it has certain hygroscopic effect, can be dropped with the moisture in draw air The surface resistance of low first seal so that the surface resistance of first seal is controlled between 10 6-8 powers, with good Antistatic performance.Meanwhile, first seal also fully meets the working condition requirement of flame-proof explosion-proof.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with Other accompanying drawings are obtained according to these accompanying drawings.
