摘要
通过对使用后失效齿轮的金相组织检验及硬度分析,找出齿轮表面产生点蚀损伤的主要原因,并提出了相应的改进措施。
By the examination ofmetallographic microstructure and the hardness analysis of failure gear after used, the main reason that the pitting attack damage appears on the surface of gear was found. The corresponding improving measures were put forward.
