Problems solved by technology

Due to the relatively high pressure during press-fitting, the shaft head generally cannot bear force, and there is no end face that can be positioned on the traditional shaft, so it is difficult to position the shaft during press-fitting, and the shaft head is easily deformed when the force is too large, and the press-fitting work efficiency Low

Abstract

The invention discloses a rotating shaft of an automatic generator. The rotating shaft comprises a step and a body. The left end of the body is provided with an external thread. The body is provided with the step. The body is provided with three spline grooves located at the right side of the step. The parts, between the spline grooves, of the rotating shaft are polished shaft bodies. By adopting the rotating shaft of the automatic generator, the problems that a rotating shaft is hard to position in the press-fitting process and the head of the shaft deforms easily due to excessive stress in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a rotating shaft of an automobile generator. Background technique [0002] The generator shaft is made of 40Cr material. In the rotor, it wears the claw pole, the inner retaining ring and the slip ring together. It has a very important position, so the requirements for it are relatively high. Due to the relatively high pressure during press-fitting, the shaft head generally cannot bear force, and there is no end face that can be positioned on the traditional shaft, so it is difficult to position the shaft during press-fitting, and the shaft head is easily deformed when the force is too large, and the press-fitting work efficiency Low. Contents of the invention [0003] According to the above deficiencies, the present invention provides a rotary shaft of an automobile generator. [0004] In order to achieve the above object, the rotating shaft of the automobile genera...
