| 摘 要： | 大模数重载汽车主减速器盆形齿轮经渗碳淬火后,齿轮齿面经常会出现裂纹。齿轮在渗碳前的预热处理工艺和渗碳工艺参数以及淬火处理,对齿轮的成分、组织及应力都会产生影响。本文通过不同工艺参数热处理后齿轮的金相检验,分析了22CrMoH钢制重载汽车盆形齿轮热处理致裂的原因,探讨解决途径和方法。

| Abstract: | Cracks frequently generated in basin gear of big modulus main reducer used in heavy load truck after carbonizing and quenching.The heat treatment process before the carbonizing,carbonization process parameter and the quench treatment all influenced the components,structure and stress in gear.In this paper,a metallographic examination of the gear was conducted after the heat treatment with different process parameters,and a study was made to investigate the factors that caused cracks in the 22CrMoH steel basin gear used in heavy load truck after the heat treatment.At the same time,several countermeasures were proposed. |
