Abstract Most of low speed rotating equipments includes large important equipments, and an equipment stoppage caused by damage of rolling element bearing brings significant losses to a plant. This paper relates to a diagnostic method of rolling element bearing in low speed rotating equipment of 100 rpm or less, and proposes a method to diagnose using AE envelope waveform of a 100 k to 1 MHz frequency region. Abnormal ity diagnosis wasafter envelope processing in addition to amplification of AE waveform. Fu...

We developed a diagnostic device that utilizes the Motor Current Signature Analysis (MCSA) to clarify the frequency domain to be focused by collecting the data which simulated various abnormalities in experimental apparatus. In addition, we found a correlation between the extent of the level and the abnormal of the generated frequency, and developed criteria. ...
