Abstract: A rolling bearing device includes: a bearing portion; an oil supply unit that has a pump; a first detection portion that detects operation of the pump; a second detection portion that detects the rotational state of the bearing portion; and a processing portion that generates determination information related to the lubrication state of the bearing portion on the basis of a detection signal from the first detection portion and a detection signal from the second detection portion. The processing portion outputs, to the pump, an instruction signal for oil supply when it is determined that operation of the pump is appropriate and that the rotational state of the bearing portion is not appropriate, and re-determines, after the lapse of a predetermined time, whether or not the rotational state of the bearing portion is appropriate.

Abstract: A pump includes a piezoelectric element that deforms when a drive voltage is applied to it, and a reservoir that has a capacity to store lubricating oil and that is at least partially deformed elastically to change in the capacity when the piezoelectric element deforms. The pump discharges the lubricating oil when the reservoir decreases in the capacity. A drive circuit unit is switchable between an application state where the drive circuit unit applies the drive voltage to the piezoelectric element, and a release state where the drive circuit unit releases the drive voltage applied to the piezoelectric element. A controller controllably switches the drive circuit unit between the application state and the release state. An electric power storage unit stores electric power that is output from the piezoelectric element when the drive voltage applied to the piezoelectric element is released.
