摘要: 某新能源汽车电机转轴条形槽热处理后的畸变无法满足尺寸精度要求,通过降低渗碳碳势、提高淬火油温度、优化淬火过程和20 μm锥度反畸变加工等措施,成功将电机转轴条形槽的畸变控制在尺寸要求范围内,且小批量生产时畸变程度未明显增加,表明此改进工艺可应用于批量生产。

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
