深沟球轴承的锯齿声故障诊断

Fault Diagnosis of Steel-sawing Noise for Deep Slot Ball Bearing

通过实验对有锯齿声的轴承的振动信号进行了分析,用包络解调法提取出了峰值明显的内圈特征谱线,分析了轴承的锯齿声噪声产生的原因,实验结果表明,该法对有锯齿声的球轴承的故障诊断简单适用.

The vibration signal of bearing noise sounding like steel sawing is analyzed in this paper. The characteristic spectral line within the frequency range of the inner ring fault is extracted by means of the methodology of envelope demodulation,and the cause of bearing noise is analyzed. The results show that the method is simple and effective for the diagnosis of the bearing noise sounding like steel swing.
