摘要
采用光学显微镜、扫描电镜、能谱仪并结合宏观断口观察,对50Z钢制造的汽车锥齿轮断齿的原因进行了分析。分析表明,由于淬火热处理不规范,引起齿轮齿尖产生细小裂纹,在外力作用下导致轮齿掉落。
Fracture causes of 50Z steel bevel gear were analyzed through macro analysis,energy spectrum analysis,SEM and metallography.The results show that the fracture of 50Z steel bevel gear is caused by the normative quenching treatment,and it causes tiny crack on the tooth of the gears and then breaks under external force action.
