Shield motor thrust bearing bush destressing tool device

Abstract

The invention relates to a shield motor thrust bearing bush destressing tool device. The shield motor thrust bearing bush destressing tool device is composed of a block device, a thrust bearing bush limiting device and a connecting device, the end face of one side of steel plates 1 is riveted with silica gel pads 3 through rivets 2 to form an end block plate 12, the silica gel pads 3 are requiredto be riveted to the end plate 1, and the end faces of the two sides of the steel plates 1 are riveted with the silica gel pads 3 through the rivets 2 to form a middle grid baffle 13. A thrust pad isprevented from being damaged due to direct contact between the steel plates and the thrust pad, the stress relieving process of machining of the thrust pad of the shield motor is achieved, the workload and the working time are reduced, the working efficiency is improved, meanwhile, stress release after machining of the thrust pad is guaranteed, subsequent stress deformation is prevented, and operation is easy and convenient.

Description

Technical field: [0001] The invention relates to a stress-relief tooling device for a thrust bearing bush of a shielded motor. Background technique: [0002] With the development of nuclear power manufacturing technology, the requirements for the machining process and precision of each component of the motor are getting higher and higher. The fineness of each component of the motor can directly reflect the overall operating performance of the motor. The higher the machining accuracy of the thrust bearing The higher the value, the more the stability of the overall rotation of the motor can be increased. The traditional processing method has a large residual stress, and the long storage time after processing will easily lead to stress deformation of the thrust pad, resulting in low machining accuracy of the thrust pad and affecting the overall performance of the motor. One of the existing stress relief methods is to place the workpiece in the air for aging stress relief. This ...

[0002] With the development of nuclear power manufacturing technology, the requirements for the machining process and precision of each component of the motor are getting higher and higher. The fineness of each component of the motor can directly reflect the overall operating performance of the motor. The higher the machining accuracy of the thrust bearing The higher the value, the more the stability of the overall rotation of the motor can be increased. The traditional processing method has a large residual stress, and the long storage time after processing will easily lead to stress deformation of the thrust pad, resulting in low machining accuracy of the thrust pad and affecting the overall performance of the motor. One of the existing stress relief methods is to place the workpiece in the air for aging stress relief. This method takes a long time to relieve stress, and the stress release is uneven, which often fails to achieve the desired effect of the workpiece. The other method is heating in the furnace Annealing stress relief, heating temperature is not guaranteed, and the heating process and range control is not uniform, the stress relief results are not satisfactory, so a new tooling device is needed for stress relief after thrust pad processing
