摘　　要：由于地铁牵引电机滚动轴承保持架运转时非线性受力、非平稳振动、无明显冲击特性及进行频谱分析时故障特征提取难度大,导致保持架故障难以识别。本文研究提出了基于共振解调方法的保持架故障诊断方案,通过应用可有效识别出地铁牵引电机存在保持架故障的轴承。Due to the non-linear,non-stationary,and no obvious impact characteristics of the rolling bearing cage of the metro traction motor during operation,and the difficulty of extracting fault features during spectrum analysis,it is extremely difficult to identify the cage fault.This paper studies and proposes a cage fault diagnosis scheme based on the resonance demodulation method.Through application,it is found that it can effectively identify the bearing with the cage fault of the metro traction motor.
