Background The rolling bearing is a main supporting component of mechanical equipment, and has the advantages of excellent dynamic performance, convenient maintenance, low cost and high supporting rigidity. The friction torque of the rolling bearing is a key factor for causing energy loss, thermal failure, vibration noise and low reliability, and the rotation flexibility is a key index for ensuring the delivery qualification rate of the rolling bearing. The rolling bearing gradually develops to high speed, low friction and high reliability. In the existing rolling bearing measurement process, the detection method for the friction moment and rotation flexibility of the rolling bearing has the problems of low measurement precision, low efficiency, complex measurement method and the like.
