摘要
20CrMnTi钢电机轴碳氮共渗和淬火后,表面硬度、心部硬度和有效硬化层深度均符合要求,但因内花键部位厚度不均匀,齿棒间距过大。在电机轴内花键薄壁部位增加一个套圈后热处理,内花键齿棒间距达到了要求。
After carbonitriding,hardening and tempering,the motor shaft of 20CrMnTi steel had desirable surface hardness,core hardness and effective hardening depth,but excessive internal spline tooth bar spacing that resulted from nonuniform thickness of internal spline.The motor shaft was heat treated after a ferrule was added to thinner wall of internal spline,as a result,its internal spline tooth bar spacing met the requirement.
