摘要
A method of automatically detecting a rolling-element bearing fault in a rotating machine is provided. The method includes receiving, from at least one sensor, a sensor signal that includes at least one frequency, converting the sensor signal to a digital vibration signal, modifying the vibration signal to generate an envelope signal, and applying a transform to the enveloped signal to generate an envelope spectrum. The method uses certain relationships among envelope spectral line amplitudes and their harmonics to detect bearing faults. As such, the method detects a bearing fault without reference to predefined fault frequencies. Systems for implementing the method are also provided.
