长沙地铁牵引电机轴承跑圈故障分析及改进

Fault Analysis and Improvement of Traction Motor Bearing Slipping in Changsha Metro

针对长沙地铁电客车三相鼠笼式异步牵引电机轴承跑圈故障,通过对电机进行解体检查和测量相关尺寸数据,分析了故障原因,并据此制定了相应的整改及预防措施,避免了类似故障的发生。

In view of the bearing slipping fault of three-phase squirrel-cage asynchronous traction motor of Changsha metro electric passenger car,the causes of fault are analyzed through the motor disassembly inspection and measurement of relevant dimensional data,and then,the corresponding corrective and preventive measures are formulated accordingly,to avoid the occurrence of similar failures.
