Abstract

See full text

A sensorized rolling element for a bearing having inner and outer races and a plurality of rolling elements disposed between the inner and outer races and includes a rolling element body having an interior surface defining a cavity, the body being disposable between the inner race and the outer race. A wireless transmitter is disposed within the cavity of the rolling element body and a piezoelectric device is disposed within the cavity so as to contact the inner surface of the rolling element body. The piezoelectric device includes a body formed of piezoelectric material and at least two electrodes electrically coupling the piezoelectric body with the wireless transmitter. The piezoelectric device is configured to generate electrical charge for powering the transmitter when the rolling element body deflects under loading applied by the inner race and/or outer race and may also be used to detect loading on the rolling element body.
