提出了通过加工热处理前“预变形等效齿面”来矫正蜗杆齿面热处理变形的方法，建立了“预变形等效齿面”的模型，在蜗杆齿面热处理变形坐标测量的基础上求得了“预变形等效齿面”的加工参数，进行了相应的加工及热处理实验，结果表明该方法行之有效。
The method of correcting the deformation of the worm gear tooth surface by processing the “pre-deformed equivalent tooth surface” before the heat treatment is proposed. The model of “pre-deformed equivalent tooth surface” is established. Based on the deformation measurement of the worm tooth surface heat treatment, The processing parameters of “pre-deformed equivalent tooth surface” were processed and the corresponding heat treatment experiments were carried out. The results show that the method is effective.
