摘要
对Ｐ６１１１Ａ联轴器断裂原因进行了断口宏观分析、断口微观分析、金相组织及化学成份分析、常规机械性能测试、断裂韧性测试、受载分析等。分析测试结果表明，该联轴器断裂是由于选材不合理及疲劳原因所致。
The reason of breakage of P6111A shaft coupling have been found out by macro-analyses and micro-analyses for the fracture, analyses of chemical constitutions and metallographic examinations, tests of routine mechanical behaviour and fracture toughness, analyses of load, etc. It has been proved that breakage of the shaft coupling resulted from nureasonable selection of matereal and fatigue.
