Description

Anti-friction bearing

Technical field

The invention belongs to technical field of bearings, and in particular to a kind of anti-friction bearing.

Background technique

Bearing is the component for support shaft or axis upper rotary part, and support is a part of its effect, and support is in fact Matter is to undertake radial load, it is understood that for it be for fixing axle, fixing axle makes it that can only realize rotation, and Its movement axially and radially is controlled, motor does not have not work if bearing, because axis may be transported to any direction It is dynamic, and require axis that can only rotate when motor work, it can not be achieved the effect of transmission in theory, moreover, axis It holds and also will affect transmission, must realize good lubrication, some bearing sheets on the bearing of high speed shaft to reduce this influence Body has had lubrication, is called prelubricated bearing, and most of bearing must have lubricating oil, be responsible for when running at high speed, due to Friction not only will increase energy consumption, is more frighteningly easy to damage bearing, is the saying that sliding friction is changed into rolling friction Unilateral, because there is kind of the thing for being sliding bearing, bearing is in use, not only breaking-out rolling between lasso, rolling element and maintenance frame Dynamic friction, and the sliding friction that can break out, thus wear bearing parts right, in order to increase the abrasion of bearing parts, Bearing accuracy stability is maintained, service life is extended, bearing steel there should be good wear-resisting property.

Bearing wearability is general at present, without excellent abrasive resistance, so designing a kind of wear-resisting shaft to solve this problem It holds.

Summary of the invention

The purpose of the present invention is to provide a kind of anti-friction bearings, to solve the problems mentioned in the above background technology.

To achieve the above object, the invention provides the following technical scheme: a kind of anti-friction bearing, including crust of the device, it is described Crust of the device bottom outside is welded with fixed block, and the fixed block bottom is welded with bracket, the bracket and fixed block junction It is interior hollow, and size specification is identical with crust of the device, the stent outer, which is inlayed, is equipped with several fixation holes, described device shell Rubber sleeve is installed on the outside of upper end, described device upper shell is equipped with dustproof cover, and the dustproof cover inlays fixation by buckle, It is welded with inner wall on the inside of the dustproof cover, described device interior of shell includes retainer, ball, limit plate, outer layer protection area, steel Item, internal layer protection zone and abrasionproof rubber, described device shell inside are welded with retainer, are welded with outer layer on the inside of the retainer Protection zone, the outer layer protection area inside are equipped with inside protection zone, are equipped with abrasionproof rubber on the inside of the inside protection zone.

Preferably, described solid there are two vertical direction is symmetrically installed there are two the fixation hole horizontal direction is symmetrically installed Determine internal surface of hole and is bonded with inner ring.

Preferably, several balls have been mounted equidistant in the retainer upper end, are equipped with limit plate on the inside of the ball, described Limit plate welds outer layer protection area.

Preferably, be made of inside the outer layer protection area wear-resisting steel plate, the internal layer protection zone and outer layer protection area it Between be welded with several steel bars.

Preferably, it is made of inside the internal layer protection zone abrasive rubber, and inner surface is coated with paint, the abrasionproof rubber Inner surface is mutually bonded with inner wall.

Technical effect and advantage of the invention: it is easy to wear to realize protection bearing upper end by rubber sleeve for the anti-friction bearing Area is not frayed, and realizing bearing by fixation hole can be stably fixed on ground, is realized by retainer and limit plate Fixed petahque track, spin track do not change, and reduce excessive friction, reduce abrasion, are realized pair by double shielding area The protection of Bearing inner, is realized inside spring bearing by steel bar, is reduced abrasion, is realized by abrasionproof rubber in bearing The protection of wall, reduction are worn caused by contacting with axis, and the anti-friction bearing structure is simple, for easily damaged local special protection, Reduce damage of the abrasion to bearing, increases bearing life.
