[0008] Further, the fixing structure includes: an end cap, a fixing bolt rotatably disposed at one end of the end cap, a positioning block fixedly mounted on the other side of the end cap, and a metal heat conducting sheet fixedly mounted on the end cap.

[0009] Further, positioning grooves are uniformly formed on the inner side wall of the bushing.

[0010] Further, the lubricating pad is an arc plate with a longer inner arc length and a shorter outer arc length.

[0011] Compared with the prior art, the utility model has the following beneficial effects: for a wear-resistant motor rotating shaft of the utility model, by installing a bushing on the motor rotating shaft body, the strength and service life of the motor rotating shaft body can be increased, and its wear can be reduced.
