AI Technical Summary

Problems solved by technology

If it is installed too tightly, it will directly press on the needle roller, which will block the axial clearance of the bearing and affect the normal operation of the bearing; if the bearing washer is installed too loosely, the bearing will fall off due to the bearing washer during the working process. Make the needle axial displacement at random, fall off from the bearing, so that the bearing can not work normally

Embodiment Construction

[0013] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

[0014] Such as figure 1 As shown, the present invention is a bearing used for high-voltage equipment switches, which is characterized in that it includes an outer ring, an inner ring, a needle roller, a support frame and a washer.

[0015] To further illustrate, the washer is fixedly installed at one end of the bearing, and a convex step is provided on the outer diameter of the outer ring.

[0016] To further illustrate, the inner surface of the outer ring facing the washer is provided with a boss that can limit the axial displacement of the needle roller.

[0017] To further illustrate, the root of the convex step on the outer diameter of the outer ring is provided with a tool undercut, and the width of the undercut is 0.5-1.2mm....

Abstract

The invention relates to a bearing for a high-voltage equipment switch. The bearing is characterized by comprising an outer ring, an inner ring, a roller pin, a supporting frame and a gasket, wherein the gasket is fixedly installed at one end of the bearing, a protruding step is arranged on the outer diameter part of the outer ring, and a boss capable of limiting the axial displacement of the roller pin is arranged on the inner surface of the end, towards the gasket, of the outer ring. According to the bearing, the axial displacement of the roller pin can be limited when the bearing works, even if the gasket falls offin the work process, the boss can prevent the roller pin from falling off from the inside of the bearing, and therefore, the bearing can work normally.

Description

technical field [0001] The invention relates to the field of high-voltage equipment switches, in particular to a bearing used for high-voltage equipment switches. Background technique [0002] Existing bearing washers can be installed too loosely or too tightly during installation. If it is installed too tightly, it will directly press on the needle roller, which will block the axial clearance of the bearing and affect the normal operation of the bearing; if the bearing washer is installed too loosely, the bearing will fall off due to the bearing washer during the working process. Make the needle axial displacement at will, fall off from the bearing, so that the bearing can not work normally. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the problem to be solved by the present invention is to provide a bearing for a switch of a high-voltage equipment. [0004] In order to solve the problems existing in the backgroun...
