Abstract
A method for removing oxide scales in a mounting hole of a bearing ring includes the steps that one end of a rotating device is wound with abrasive paper to form a circle of flexible abrasive particles; the end, where the abrasive paper is wound, of the rotating device extends into the mounting hole of the bearing ring; when the rotating device rotates, the abrasive paper on the rotating device is attached to the inner wall of the mounting hole under action of centrifugal force, and friction is generated between the abrasive particles on the abrasive paper and the inner wall of the mounting hole under the driving effect of a rotary head so that the oxide scales on the inner wall of the mounting hole can be removed. According to the method, the oxide scales in the mounting hole of the bearing ring are removed thoroughly due to the effect of high-speed rotary friction, in this way, the appearance of the mounting hole is bright, and inspectors can check the conveniently.
