多头蜗杆的加工质量,取决于正确的分头方法,如果加工中分头出现误差,将使所加工的多头蜗杆的螺距不等,从而严重影响蜗杆与蜗轮的配合精度,使传动不准确,并且降低零件的使用寿命。多头蜗杆加工的分头方法,工艺上分为2类,即轴向分头法和圆周分度分头法。轴向分头法是当车好一条螺 The processing quality of the multi-head worm depends on the correct sub-head method. If there are errors in the processing, the pitch of the multi-head worm will be different, which will seriously affect the cooperation between the worm and the worm gear, inaccurate the transmission and reduce the parts The service life. Multi-head worm processing methods, the process is divided into two categories, namely the axial sub-method and the circumferential sub-division method. Axial division method is when the car is a snail
