Abstract

The utility model relates to a low-wear cage for bearings, which comprises a cage body, steel balls are installed in the pockets of the cage body, the inner surface of the pockets is provided with convex lines protruding toward the center of the pockets, and the convex lines The inner arc surface of the pocket is extended and arranged to form a ring-shaped structure, and the two ring-shaped ridges are relatively vertically arranged. In the utility model, a convex line is arranged in the pocket hole, and the steel ball contacts with the convex line, thereby greatly reducing the contact area between the pocket hole and the steel ball, reducing wear and prolonging the service life.

Description

Low-wear cages for bearings

technical field

The utility model relates to the technical field of bearings, in particular to a cage in the bearing.

Background technique

In the prior art, the pocket of the cage of the bearing is a spherical structure. After the pocket is wrapped with steel balls, the contact area between the two is relatively large, so that the friction between the two is relatively large, which will cause serious wear of the steel ball and is prone to The phenomenon of steel ball jamming, the wear of the steel ball and the cage shortens the service life of the bearing.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the applicant conducts research and improvement, and provides a low-wear cage for bearings, which has low friction with steel balls and has the characteristics of long service life.

In order to solve the above problems, the utility model adopts the following scheme:

A low-wear cage for bearings, comprising a cage body, steel balls are installed in the pockets of the cage body, the inner surface of the pocket is provided with a raised line protruding toward the center of the pocket, and the raised line runs along the pocket The inner arc surface is extended and arranged to form a ring-shaped structure, and the two ring-shaped ridges are relatively vertically arranged.

The technical effect of the utility model is:

In the utility model, a convex line is arranged in the pocket hole, and the steel ball contacts with the convex line, thereby greatly reducing the contact area between the pocket hole and the steel ball, reducing wear and prolonging the service life.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure: 1. Cage body; 2. Pocket hole; 3. Steel ball; 4. Raised strip.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described.

As shown in Figure 1, the low-wear cage of the bearing of this embodiment includes a cage body 1, steel balls 3 are installed in the pocket holes 2 of the cage body 1, and the inner surface of the pocket hole 2 is provided with a ball towards the center of the pocket hole 2. The protruding convex strips 4 are arranged extending along the inner arc surface of the pocket hole 2 to form a ring-shaped structure, and the two annular convex strips 4 are arranged vertically relative to each other.

In the utility model, the convex strip 4 is arranged in the pocket hole 2, and the steel ball 3 is in contact with the convex strip 4, which greatly reduces the contact area between the pocket hole 2 and the steel ball 3, reduces wear and tear, and prolongs the service life.

The above-mentioned embodiments are preferred implementation modes of the present utility model, which are only used to facilitate the description of the present utility model, and are not intended to limit the present utility model in any form. Anyone with ordinary knowledge in the technical field, if they do not depart from this utility model Within the scope of the technical features mentioned in the utility model, the equivalent embodiments that make partial changes or modifications using the technical content disclosed in the utility model, and do not deviate from the technical features of the utility model, still belong to the technical features of the utility model within range.
