[0032] Working process: When the device is in use, the external power supply is energized. When the vibration of the bearing needs to be detected, the inner ring 2 of the bearing is fixed and the outer ring 1 of the bearing rotates. When the outer ring 1 of the bearing rotates, the steel ball 67 rotates at the same time. Under the elastic force of the spring telescopic rod 65, the steel ball 67 pushes the passive movable plate 69, the long column 66 and the steel ball 67 to move, so that the outer side of the steel ball 67 keeps fitting with the inner side of the outer fixed ring 3.
