[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure the rotation accuracy. At the same time, bearings are also widely used in the steering gears of automobiles. During operation, a certain inclination angle will be generated between the outer ring and the inner ring of the bearing. During production, it is necessary to accurately measure the deflection angles of the inner and outer rings of the bearing. Most of the existing measurements of bearing deflection angles are carried out manually.

[0003] According to the authorized announcement number CN 213067425 U, a bearing performance detection device is disclosed, including an installation box. A motor is fixedly installed inside the installation box. The motor includes a driving end. The driving end is fixedly connected to a rotating rod. A magnetic tray is fixedly installed at the top of the rotating rod. A bearing is placed on the magnetic tray. A support column is fixedly installed at the top of the installation box. The support column is slidably connected to a sleeve. A threaded through hole is penetrated through the sleeve. A lead screw is threadedly connected inside the threaded through hole. One end of the lead screw is fixedly installed with a rotating block. The other end of the lead screw abuts against the support column. A sliding rod is fixedly installed on the outer wall of the sleeve. The sliding rod is slidably connected to a slider. A through hole is penetrated through the outer wall of the slider.
