[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, the present invention proposes a bearing retaining sleeve inner wall cleaning device, including a fixed frame 1, which is through the front and rear and is shaped like a U-shape in the main view. A hollow shaft 5 is rotatably installed on the top of the inner wall of the fixed frame 1. The hollow shaft 5 and the fixed frame 1 are rotatably connected by a bearing. The hollow shaft 5 is hollow inside and the top opening is connected to the outside. A number of inclined air holes 16 are evenly distributed in a ring array on the outer surface of the hollow shaft 5. The angle between the air outlet direction of the inclined air holes 16 and the axis of the hollow shaft 5 is 60°≥a≥30°. Therefore, the direction of the compressed gas inside the hollow shaft 5 when discharged from the inclined air holes 16 is inclined downward.

[0023] A baffle 17 is rotatably fitted onto the outer surface of the hollow shaft 5 above the inclined air hole 16. The baffle 17 and the hollow shaft 5 are rotatably connected by a bearing. The lower surface of the baffle 17 is open, and the diameter of the opening and the outer diameter of the locking bushing are greater than or equal to the outer diameter of the locking bushing. A drive box 4 and a compressed air pump 2 are fixedly installed on the upper surface of the fixed frame 1, and the hollow shaft 5 passes through the drive box 4.
