第一部分 工艺设计说明书
1.零件图工艺性分析
1.1零件结构功用分析
从传动轴的受力分析可知，它受扭转一弯曲复合作用力，由于其承受中等载荷，工作又较平稳，冲击力很小，所以可采用优质碳素结构钢的45号钢，坯料用热轧圆钢。为了改善组织、提高力学性能，坯料要经过正火热处理
1.2零件技术条件分析
外圆尺寸精度 ：φ30k6，φ30f7两节，φ25k6，φ20h6，及M24X1.5的螺纹；
外圆形状位置精度 ：要求为φ30f7两轴节相对φ30k6，φ20h6，φ25k6
φ30f7两轴节表面需高频淬火；
外圆表面质量 ：φ30k6，φ30f7两节，φ25k6，φ20h6的表面质量要求 Ra均为0.8um，
其它面Ra为12.5um
