基于振动频谱和电信号频谱的电动机轴承故障分析

Analysis of Motor Bearing Fault Based on Vibration Spectrum and Electric Signal Spectrum

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.
