应用振动波形频谱分析实行电机轴承预知检修

Application of Frequency Spectrum Analysis of Vibration Waveform to Maintain Bearing in a Motor Beforehand

通过对振动波形的频谱进行分析、计算，利用现有仪器进行检测，实行对设备的预 知检修，收到了较好的效果。

Based on analysis and calculation of frequency spectrum of vibra- tion waveform, apparatuses were inspected using existing instruments so as to maintain the apparatuses beforehand. Better effects are obtained.
