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, et

Embodiment Construction

[0019] like Figure 1~3 As shown, a deep groove ball bearing cage removal method disclosed in the present invention uses bearing removal auxiliary tooling 2 to position and support the cage of the deep groove ball bearing to prevent the cage from rotating, and then place it on the workbench of the drilling machine 1, The drill bit of the drilling machine 1 removes all the rivet head cuttings from the cage of the deep groove ball bearing 3, so that the two frames of the cage of the deep groove ball bearing 3 are separated to complete the disassembly.

[0020] Further, the bearing removal auxiliary tooling used in the present invention is as follows: the bearing removal auxiliary tooling 2 includes a base plate 21, and the base plate 21 is provided with an annular retainer positioning boss 22, and the retainer positioning boss 22 is positioned by a spherical surface. The support part 221 and the cage beam positioning support part 222 are arranged alternately in order to form a ...

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...
