Deep groove ball bearing retainer dismantling method

Abstract

The invention relates to a deep groove ball bearing retainer dismantling method. A retainer of a deep groove ball bearing is positioned and supported by means of an auxiliary bearing dismantling tool so as to be prevented from rotating and then is placed on a working table of a drilling machine, drilling cuttings on the heads of all rivets of the retainer of the deep groove ball bearing are removed by means of a drill bit of the drilling machine, and thus two retainer bodies of the retainer of the deep groove ball bearing are separated to complete dismantling. The deep groove ball bearing retainer dismantling method has the advantages that dismantling operation is easy and convenient, all components of the bearing are prevented from being damaged, accurate bearing disassembly analysis is achieved, and reutilization of qualified components of the bearing is achieved.

Description

technical field [0001] The invention relates to a cage dismantling method for dismantling and decomposing a deep groove ball bearing. Background technique [0002] Deep groove ball bearings are rolling bearing One of the most common types. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The cage is composed of two wavy wire cage monomers 31 riveted by rivets 32 (such as figure 1 shown). The role of the wavy cage is to keep the rolling elements in the correct position when the bearing is running. Once the wavy cage is damaged, it will usually cause the overall failure of the bearing. In order to analyze the cause of unqualified bearings, it is necessary to disassemble the unqualified bearings. [0003] The existing dismantling methods for deep groove ball bearings include: splitting the bearing in half, this method will completely destroy the various parts of the bearing, which is not only unfavorable...

AI Technical Summary

Problems solved by technology

[0003] The existing dismantling methods for deep groove ball bearings include: splitting the bearing in half, this method will completely destroy the various parts of the bearing, which is not only unfavorable for analysis, but also damages the qualified parts of the unqualified bearing, making it impossible to Secondary use, resulting in waste of resources

The other is hard disassembly of the wavy cage, such as prying, punching, etc. The wavy cage is deformed and cannot detect various dimensions, and the roughness and roundness of the bearing steel ball raceway are damaged.

Therefore, there are no disassembly tools and methods for deep groove ball bearings, which cause great inconvenience to the failure analysis of deep groove ball bearings and the secondary utilization of qualified parts, which is not conducive to the improvement of deep groove ball bearings.
