    摘要： An active piezoelectric spindle bearing preload adjustment mechanism includes a preload adjustment assembly located between an inner ring and an outer ring of two bearings, and an internal generator mounted at a selected location in a spindle. The preload adjustment assembly includes a spacer ring set and a piezoelectric actuator located in the spacer ring set. The rotation speed of the spindle is changeable to enable the internal generator generating selected amount of power and voltage for controlling extension or contraction length of the piezoelectric actuator whereby to change slide distance between the inner and outer ring for controlling bearing preload value.

    摘要： 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.
