【摘要】 对42CrMo钢减速器齿轴的断口进行分析,对齿轴硬度进行检测并对其金相组织进行了分析。结果表明,齿轴的金相组织未达到要求造成硬度不足,从而使齿轴发生剪切断裂。根据齿轴的技术要求制定出合理的热处理参数。更多还原

【Abstract】 The fracture of 42CrMo steel reducer gear shaft was analyzed.The hardness of reducer gear shaft was tested and its microstructure was analyzed.The results show that the microstructure can’t reach the requirements,which causes inadequate hardness of gear shaft,and thus it results in the shear failure of gear shaft.According to the technical requirement,the reasonable heat treatment process for gear shaft was determined.更多还原
