Bearing retainer rolling body dismounting device

Abstract

The invention discloses a bearing retainer rolling body dismounting device. The bearing retainer rolling body dismounting device comprises a base, a supporting frame is arranged on the base, a pressure applying mechanism is arranged on the supporting frame and comprises a movable bolt connected to the supporting frame in a threaded mode, an extension rod capable of abutting against a rolling bodyis vertically arranged at the lower end of the movable bolt, a sliding groove is formed in the upper end face of the base, a pair of clamping plates used for axial limiting of a retainer is arranged in the sliding groove in a sliding mode, and the clamping plates are fixed in the sliding groove through fixing pieces. The bearing retainer rolling body dismounting device is simple in structure, uniform in force application, not prone to slipping and capable of reducing damage and deformation of the surface of the rolling body and the retainer.

Description

technical field [0001] The invention relates to a device for unpacking rolling elements of a bearing cage. Background technique [0002] The cage (that is, the bearing cage, also known as the bearing cage) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing Inside. [0003] At present, such as in needle roller bearings, there is an interference fit between the needle roller and the cage. To realize the needle roller falling off the cage, a certain force must be applied to the end surface of the roller. However, during the disassembly process, due to Uneven application of force can easily lead to deformation of the cage and damage to the surface of the needle roller after the force is applied. After disassembly, the accuracy of the needle roller and the size of the cage cannot be guaranteed, resulting in changes in the size ...

[0003] At present, such as in needle roller bearings, there is an interference fit between the needle roller and the cage. To realize the needle roller falling off the cage, a certain force must be applied to the end surface of the roller. However, during the disassembly process, due to Uneven application of force can easily lead to deformation of the cage and damage to the surface of the needle roller after the force is applied. After disassembly, the accuracy of the needle roller and the size of the cage cannot be guaranteed, resulting in changes in the size of the sample, making it impossible to measure accurately Unqualified sample delivery of new products caused by unqualified values ​​or dimensions can easily affect subsequent test results

In addition, this method is very unsafe to a certain extent, because during the disassembly process of the metal cage, it is often necessary to use tools (such as a screwdriver) to disassemble the needle roller, but because there is no good force point to ensure disassembly The normal trajectory of the tool is easy to slip off on the needle roller, thus acting on the hands of the dismantling personnel, causing personal injury
