摘　　要：对电动机轴承振动和电信号频谱特征值进行诊断分析，有效预判了轴承因润滑不良导致的故障，并根据轴承故障机理提出规范了电动机轴承可靠润滑的方案。By making an analysis and diagnosis on the feature of the vibration and electric signal spectrum of motor bearing, predict that the fault is resuhed from bad bearing lubrication. According to the fault mechanism, put forward a reliable lubrication plan for the motor bearing.

关 键 词：电动机轴承 振动频谱 电信号频谱 润滑
