中文摘要：针对汽车变速器中间齿轮轴在渗碳淬火热处理后齿型、齿向的畸变问题，分析了其产生原因。通过热处理工艺改进，调整了渗碳淬火工艺参数并改变了装炉方式，提高了齿轮轴接触精度和使用寿命。
英文摘要：According to the gear distortion of transmission countershaft treated by carburizing and quenching, its reason was analyzed. The improved heat treatment process was obtained by adjusting technology parameters and changing parts loading mode. As a result, the contact accuracy and life of countershaft were improved.
