Abstract:
Disclosed is a torque measurement method for a rolling bearing device (10) comprising a shaft (21) formed as a cylindrical column, a cylindrical sleeve (23) disposed coaxially to the shaft at a predetermined distance from the outer surface thereof, and a rolling bearing disposed between the shaft and the sleeve with the inner ring fixed to the shaft and the outer ring fixed to the sleeve, wherein a load cell (44) equipped with a measurement terminal (51) capable of detecting torque is used to measure the torque of the rolling bearing device by causing one element among the shaft or the sleeve of the roller bearing device to rotate, pressing the measurement terminal against the other part with a prescribed force, and detecting the frictional force on the measurement terminal.
