通过化学成分分析、金相检验、硬度测试等方法对 K10发动机驱动轴断裂原因进行了分析，结果表明20CrMo钢制驱动齿轮轴过早失效断裂是由于热处理过程中该轴心部未淬透和负载增大所至。
通過化學成分分析、金相檢驗、硬度測試等方法對 K10髮動機驅動軸斷裂原因進行瞭分析，結果錶明20CrMo鋼製驅動齒輪軸過早失效斷裂是由于熱處理過程中該軸心部未淬透和負載增大所至。

Possible reasons of driving shaft fracture of K10 engine were analyzed by means of chemical analysis, met-allographic examination and hardness testing. Results show that the early failure and fracture of 20CrMo steel made driving shaft is caused by incomplete hardening of the axis and increasingly growing load.
