Method and apparatus for location of anomalous signal in a radial bearing

摘要

A method for locating a source position of an anomalous signal in a radial bearing (2) comprises using a signal detection sensor (7), an inner-ring positional detection sensor (8) for detecting a rotational position of a bearing inner ring (3), and a ball positional detection sensor (11) for detecting a revolution position of bearing-balls (5). 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 (5) and the inner or outer ring (3, 4) at a time of anomalous signal generation, within a load zone (2&thetas;), as an anomalous signal source position. <IMAGE>
