The method of connecting and fixing the photoelectric encoder shaft and the motor or traction machine shaft directly affects the application of the photoelectric encoder. The key connection will produce eccentricity and radial stringing, which cannot meet the coaxiality of the rotation center of the photoelectric encoder and the center of the fixing hole. Especially in the case of high-code photoelectric encoders, the error is too large and cannot be used.

[0003] Among them, the announcement number CN201373750Y discloses a photoelectric encoder locking ring, which is a component of a photoelectric instrument. The locking screw is threadedly connected to the two sides of the opening of the ring body. A circular hole with a through groove is opened at 120° clockwise from the opening of the ring body, and a circular hole with a through groove is opened at 120° counterclockwise from the opening of the ring body. The advantages of this utility model are novel structure and uniform locking. However, there are still defects in this technical solution:
