摘要: A method is provided of identifying a rotating bearing defect featuring the steps measuring vibration to obtain waveform signal; filtering signal remove unwanted frequencies; enveloping filtered an enveloped low frequency time waveform; and synchronizing running speed in such way preserve phase relationship between tachometer pulse synchronized waveform. The may include step rotational bearing; comprises with tachometer.
