Description

Multilayer sliding bearing with function of resistance to wears

Technical Field

The utility model relates to the technical field of multilayer sliding bearings, in particular to a multilayer sliding bearing with an abrasion-resistant function.

Background

The multi-layer sliding bearing is a sliding bearing with a bearing bush made of several layers of different materials, and the bearing is an important part in mechanical equipment and is used for supporting a mechanical rotating body, reducing the friction coefficient in the movement process and ensuring the rotation precision of the mechanical rotating body. However, after the working time of the existing multilayer sliding bearing is long, abrasion can be generated, the rotation precision of the rotating body is further influenced, the service life is short, the working efficiency is low, and the practicability is poor.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a multilayer sliding bearing having an anti-wear function, so as to solve the problem of the poor anti-wear function of the multilayer sliding bearing proposed in the above-mentioned background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a multilayer slide bearing with function of resistance to wears, includes outer lane, inner circle, holder and ball, the outer lane passes through the holder and is connected with the inner circle, be equipped with a plurality of groups ball on the holder, the lateral surface of outer lane is equipped with the protective layer, the internal surface of outer lane and the surface mounting who is located the holder have the wearing layer.

Preferably, an elastic ring is installed on the inner surface of the inner ring, and a shock pad is arranged above the elastic ring.

Preferably, the surface of the outer ring is provided with a plurality of groups of oil inlets, and the oil inlets are communicated with the oil grooves of the inner ring.

Preferably, the surface of the wear-resistant layer is provided with corrugations.

Preferably, the protective layer is a copper powder layer, and the thickness of the copper powder layer is 0.3 mm.

Compared with the prior art, the utility model has the beneficial effects that:

the protective layer on the outer surface of the outer ring is made of copper powder, so that heat generated by friction can be well dissipated and removed, the heat dissipation performance is good, and the service life of the outer ring is prolonged; the damping pad and the elastic ring are arranged, so that the damping effect on the ball can be realized in the rolling process, the inner ring can be protected, the friction generated in the operation process is reduced, and the practicability is good; the wear-resisting layer can improve the wear resistance between the outer ring and the retainer in the operation process, thereby improving the rotation precision of the rotating body, prolonging the service life of the rotating body and achieving good use effect.
