Description

technical field

[0001] The invention relates to the field of subway vehicle state detection, in particular to a portable subway traction motor bearing state detection device. Background technique

[0002] The traction motor bearings of subway vehicles are an important structure for transmitting torque and bearing loads. The working environment is harsh, and the bearings run under heavy loads for a long time, which will inevitably cause problems such as corrosion or wear. The small defects of parts and components will cause different amplitude vibrations to the car body after a long period of train operation, which will accelerate the damage of the motor bearing of the vehicle and seriously threaten the operation safety of the train. Real-time and effective diagnosis and early warning of the motor bearing will not only It can ensure the safety of vehicle operation, reduce maintenance costs, promote intelligent diagnosis and provide support for train operation and intelligent ...
