Abstract

Abstract: Distortion of the shaft bar groove of a new energy vehicle motor during heat treatment could not meet the dimensional accuracy requirements. By reducing the carburizing potential, increasing the quenching oil temperature, optimizing the quenching process and anti-distortion processing with a 20 μm conicity, the distortion of the motor shaft bar groove is successfully controlled within the range of dimensional accuracy requirements, and the distortion is not significant increase in small batch production, which indicates that the improved process can be applied to batch production.

Key words: bar groove, carburized quenching, conicity, machining of anti-distortion
