摘要
用宏观断口分析、化学检验、力学性能测定、低倍检查、金相组织及夹杂物评定鉴别、受力分析及强度寿命定量估算的方法，对人字轮被动齿轴端断裂失效原因进行分析，并提出改进措施。
The failure cause of the driven gear shaft on a double helical spur gear is analyzed by using macro-fracture analysis,chemical test,determination of mechanical priperties,macroscopic examination ,evaluation and distinguishing of metallographical structure and inclusion,stressed state analysis and quantitative evaluation method of strength and life,and the improved measures are put forward.
