Since it is prior art, no further description is given in the present specification, and it is not shown in the figure.

[0025] In specific implementation, after the device is used for a period of time, due to the rotating friction, the surface of the friction contact is prone to generate chips. The bearing body 3 is provided with the chip removal groove 301, and the chips generated by the friction fall into the chip removal groove 301, and then fall into the base 5 through the chip removal opening 13 in the chip removal groove 301. Then the motor 7 is started, and the spiral feeder 9 is driven to rotate, so that the chips falling into the base 5 are moved along with the spiral feeder 9 to the opening of the base 5 under the rotation of the spiral feeder 9, until the chips are moved out of the base 5, thereby reducing the accumulation of chips in the base 5 and avoiding the blockage of the chip removal groove 301 by the chips accumulated for a long time.

[0026] Please refer to Figure 2And Figure 4 As shown in the figure, the shaft 1 is provided with a gas pump 10, the blowing end of the gas pump 10 is connected with a gas pipe 12, the other end of the gas pipe 12 penetrates the outer wall of the shaft 1 and is connected with a gas nozzle 14, the gas nozzle 14 is arranged in the chip removal groove 301 and does not contact the bottom surface of the chip removal groove 301, the inner wall of the shaft 1 is connected with an extension plate 11, the gas pump 10 is connected with the outer wall of the extension plate 11, and the gas pipe 12 is made of a deformable material.

[0027] In actual implementation, the size of the debris generated by the device friction is different, and the debris is easy to block the debris discharge port 13 during falling. At this time, the gas pump 10 is started, the air in the gas pump 10 is compressed and then output from the gas pipe 12, and then sprayed from the gas nozzle 14. Since the distance between the gas nozzle 14 and the bottom surface of the chip removal groove 301 is relatively close, when the gas flow is sprayed, the gas flow is scattered due to the blockage of the bottom surface of the chip removal groove 301, so that the gas flow is circulated, and the blockage of the debris in the debris discharge port 13 is reduced by the gas flow.
