ABSTRACT:
A method for locating a source position of an anomalous signal in a radial bearing comprises using a signal detection sensor, an inner-ring positional detection sensor for detecting a rotational position of a bearing inner ring, and a ball positional detection sensor for detecting a revolution position of bearing-balls. Signals from the signal detection sensor, inner-ring positional detection sensor, and ball positional detection sensor are used to locate positions of contact between balls and the inner or outer ring at a time of anomalous signal generation, within a load zone, as an anomalous signal source position.
