Abstract

The invention discloses a motor rotation shaft which comprises a cylindrical body. Cross section diameters of the two ends of the body are smaller than the cross section diameter of the middle section of the body. An installation hole coaxial with the body is formed in one end surface at one end of the body, and a pin hole which is vertical to an axis of the body and penetrates through the body axis is formed in a shaft surface at the other end of the body; and a locating groove is formed in the middle section of the body, and an inner retaining ring is arranged at the edge of the middle section of the body. According to the mode, the motor rotation shaft is simple in structure, low in manufacture cost, high in mechanical efficiency, even in stress and not easy to deform.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a motor shaft. Background technique [0002] In the prior art, there are certain defects in the production of the motor shaft. The error is relatively large during use. When pressing, the shaft head is easily deformed due to excessive force, and the operation is unstable, resulting in energy loss. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a motor shaft with simple structure, low manufacturing cost, high mechanical efficiency, uniform force, and not easily deformed. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a motor shaft, including a cylindrical main body, the cross-sectional diameter of the two ends of the main body is smaller than the cross-sectional diameter of the middle section, and the end surface of one end of th...
