Abstract
A system for anticipating low-speed bearing failure triggers a notification when a noise generated by the low-speed bearing exceeds a threshold. The system predicts failure far in advance of the actual failure. The system includes an accelerometer for detecting the noise generated by the bearing. The signal produced by the accelerometer is processed using a band pass filter, an amplifier/rectifier, an averaging filter, and a voltage to current converter. The signal and raw data are transmitted to a remote monitoring system, such as a computer. The signal is further analyzed, such as to produce a best-fit line. When the signal exceeds a predetermined threshold, such as when the amount or the slope of the best-fit line exceeds a value, the remote system notifies a monitor to schedule maintenance.
