A device for removing a bearing of a traction motor and a method applied to the device

Abstract

The invention discloses a device for dismounting a bearing of a traction motor, comprising: a positioning mechanism fixedly arranged on a rotor assembly and a moving mechanism movable relative to the positioning mechanism; the positioning mechanism is provided with a positioning surface, and the moving mechanism is provided with a The positioning surface cooperates to enable the rotor assembly to achieve radial and axial positioning. Compared with the prior art, the dismantling device of the traction motor bearing provided by the present invention avoids the dismantling process of the bearing after the rotor assembly is separated from the stator assembly, simplifies the dismantling process of the traction motor bearing, and reduces the cost of bearing disassembly. The configuration requirements and costs of human resources and material resources shorten the disassembly time of traction motor bearings and improve work efficiency. The invention also discloses a dismantling method of the traction motor bearing applied to the dismantling device of the traction motor bearing.

Description

technical field [0001] The invention relates to the technical field of motor maintenance, and more specifically relates to a device for dismounting a bearing of a traction motor. In addition, the present invention also relates to a method applied to the above-mentioned dismounting device of the traction motor bearing. Background technique [0002] With the rapid development of rail transit, the operation and maintenance requirements and technical level of rail vehicles are also increasing. The bearing of the traction motor is the core force-bearing component. In order to ensure the safe operation of the vehicle, the maintenance of the bearing is extremely critical, and it must be inspected or replaced within the specified time or kilometers. [0003] Traction motor bearings need to be overhauled or replaced regularly. In the prior art, when overhauling or replacing traction motor bearings, the motor needs to be dropped off and returned to the factory, and professional tools...

AI Technical Summary

Problems solved by technology

The entire disassembly period is long, the process is cumbersome, a specific site and special tooling are required, and the maintenance cost and maintenance resource consumption are large

Especially when the faulty bearing needs to be disassembled, the above process cannot be simplified, resulting in a large time span for fault analysis and resolution, which affects the normal production process. The installation method of the traction motor bearing in the prior art is as follows: figure 1 As shown, the rotor 01 is set on the central axis
