High-strength motor shaft

Abstract

The invention discloses a high-strength motor shaft. The high-strength motor shaft comprises a front connection rod and a rear connection rod, wherein a knurled rod, a first polished rod and a second polished rod are sequentially connected between the front connection rod and the rear connection rod; splines are arranged on the outer circle surfaces of the front connection rod and the rear connection rod; the splines on the front connection rod extend to the end side of the front connection rod; straight-line knurls are rolled on the outer circle surface of the knurled rod; a plurality of axial bar grooves are distributed at equal intervals in the outer circle surface of the first polished rod; a plurality of cross-shaped reinforcing groove nodes are distributed on the bar grooves. The high-strength motor shaft is simple and reasonable in structure, convenient to mount and use, small in possibility of skidding in the radial direction in the operation process, relatively good in torsion resistance, capable of conveniently locating and welding rib plates, good in stability and not easy for stress concentration and deformation; the precision of the motor shaft is effectively guaranteed; the service life of the motor shaft is prolonged; the normal operation of the motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-strength motor shaft. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor shaft is one of the important components, and its performance directly affects the performance of the entire motor. The structure of the traditional motor shaft is unreasonable, the installation and use are not convenient enough, the torsion resistance is poor, and it is easy to cause parts to slip. Contents of the invention [0003] The purpose of the present invention is to provide a high-strength motor shaft to solve the problem that the traditional motor shaft structure in the prior art is not reasonable enough, the installation and use are not convenient enough, the torsion resistance is poor, the parts are likely to slip, the rib plate positioning welding is inconvenient, a...
