摘　　要：为进行轴类的参数设计,减少热处理后校正工件尺寸所需的二次加工,分析了传动轴件热处理造成的尺寸变形量与几何设计间的关联性,剖析热处理变形的原因以掌握工件几何上的设计重点,并定义平均直径变形(ADC)指标及直径变形偏移指标(DDC);最后采用田口法分析影响热处理淬火尺寸变形的主要控制与外界干扰。结果表明,节径及模数对于齿槽段平均直径变形与直径变形偏移量的影响十分显著;齿槽段两端直径对齿槽段直径变形偏移量的影响十分显著,但对平均直径变形无明显的影响。In order to design the type of axle parameter and reduce correction workpiece size of secondary processing in heat treatment. The relevance of the size distortion number and geometric design on the transmission shaft parts heat treatment was analysed. Further the reason of the heat treatment deformation was analysed so that grasping the design key of the parts workpiece, and defining ADC and DDC. At last the main control and external interference on the heat treatment quenching size deformation was analysed...
