Abstract

The invention discloses a novel bearing, and belongs to the field of mechanical part processing technology. A conventional bearing has a defect that bearing failure is caused because parts are deformed due to temperature rising in an operation process. The bearing comprises an inner ring, rolling balls, a retainer and an outer ring; the rolling balls are positioned and mounted between the inner ring and the outer ring through the retainer, and the inner wall of the inner ring and the outer wall of the outer ring are each arranged into a concave-convex structure. The inner wall of the inner ring and the outer wall of the outer ring are each arranged into the concave-convex structure, so that the bearing use effect is ensured, the overall mass of the bearing is also reduced, meanwhile, the radiating area is enlarged, the bearing is allowed to be fast in heat dissipation during the operation process, effects of temperature deformation of the parts is reduced, and the service life of the bearing is prolonged.

Description

A kind of novel bearing

Technical field

The invention belongs to component of machine processing technique field, especially relevant with a kind of novel bearing.

Background technique

Bearing is very extensive as conventional mechanical part purposes, existing bearing generally comprises outer ring, inner ring, ball and retainer, total quality is larger, in operation process, between all parts, can produce some frictions, each part temperatures is raise, each parts are heated and cause geometrical shape change unbalanced, especially inner ring and outer ring thickness are relatively thin, be subject to temperature variation larger, in the time that the spacing between the inwall of outer ring and the outer wall of inner ring is less than the diameter of ball, in operation process, there is the phenomenon that ball " is killed " in bearing, make bearing failure, bearing is short working life.

Summary of the invention

Object of the present invention is intended to overcome existing bearing and in running, is subject to temperature rising to cause each part distortion to cause the defect of bearing failure, provides a kind of lighter weight, the bearing of rapid heat dissipation.

For this reason, the present invention is by the following technical solutions: a kind of novel bearing, comprise inner ring, ball, retainer and outer ring, ball by retainer location and installation between inner ring and outer ring, it is characterized in that, described inner ring inwall and outer ring outer wall are set to concaveconvex structure.

Use the present invention can reach following beneficial effect: by concaveconvex structure being set at inner ring inwall and outer ring outer wall, not only ensure the using effect of bearing, reduced bearing integral quality simultaneously, expanded heat diffusion area simultaneously, make bearing rapid heat dissipation in running, reduce the impact of each parts temperature distortion, extended the working life of bearing.

Brief description of the drawings

Fig. 1 is cross-sectional view of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.

As shown in Figure 1, the present invention includes inner ring 1, ball 3, retainer 4 and outer ring 2, ball 3 is by retainer 4 location and installation between inner ring 1 and outer ring 2, and described inner ring 1 inwall and outer ring 2 outer walls are set to concaveconvex structure.

Claims (1)

1. a novel bearing, comprise inner ring (1), ball (3), retainer (4) and outer ring (2), ball (3), is characterized in that: described inner ring (1) inwall and outer ring (2) outer wall are set to concaveconvex structure by retainer (4) location and installation between inner ring (1) and outer ring (2).
