Problems solved by technology

[0002] At present, most electric vehicle motor shafts on the market are made of 45 steel, heat-treated and tempered, and rectangular splines are used to connect the electric vehicle gearbox. Due to the large fit gap of the rectangular splines, the transmission impact is large, and the spline connection is likely to fail. Great impact on service life and use safety

Abstract

The invention relates to an electromobile motor rotary shaft. The outer circle surface of an output end of the motor rotary shaft is provided with an involute spline; spline teeth of the involute spline are of a herringbone angle shape; and the motor rotary shaft is prepared from 20CrMnTi super-quality alloy steel through heat treatment carburizing and quenching. The electromobile motor rotary shaft is high in bearing capability, has good drive stability, is low in noise and high in product assembling efficiency, prevents drive axial force from influencing the rotary shaft, is suitable for being used in high-speed and heavy loading conditions, and is beneficial to improving the practicability of the electromobile.

Description

technical field [0001] The invention relates to a rotating shaft, in particular to a rotating shaft of an electric vehicle motor. Background technique [0002] At present, most electric vehicle motor shafts on the market are made of 45 steel, heat-treated and tempered, and rectangular splines are used to connect the electric vehicle gearbox. Due to the large fit gap of the rectangular splines, the transmission impact is large, and the spline connection is likely to fail. The service life and use safety are greatly affected. Contents of the invention [0003] Aiming at the shortcomings of the rectangular spline connection of the electric vehicle motor shaft in the prior art, the present invention provides an electric vehicle motor shaft with small connection and matching impact, safe use and long service life. [0004] The present invention adopts the following technical solutions: a motor shaft of an electric vehicle, which is characterized in that an involute spline is p...
