Bearing temperature, dynamic torque detection testing method and testing device

The present invention relates to a bearing manufacturing quality detection technology, specifically a bearing temperature, dynamic torque detection testing method and a testing device. The method comprises applying a pretightening force of a predetermined direction on a detected bearing to drive the bearing to rotate; detecting temperature and dynamic torque of the detected bearing when the bearing is rotated; and when the bearing temperature detection data reaches a set temperature value within a preset time, and/or the bearing dynamic torque detection data reaches a set torque value within a preset time, judging the detected bearing is damaged or not. The device comprises a bearing pretightening and dragging mechanism, a bearing temperature, a torque detection unit and a bearing damage judging unit, through applying a pretightening force of a predetermined direction on the detected bearing to drive the bearing to rotate, the temperature and dynamic torque of the bearing when the bearing is rotated can be de
