我厂为某设备加工如图1所示的铜蜗轮时,因模数小(m=1),齿数少(Z=26),在Y3150E上无法加工,而只能在车床上加工。此种方法简单易行,能满足一般精度要求,经济实用。一、工作原理根据丝锥加工螺孔时可自动引进的原理,使滚刀旋转而带动蜗轮自转,完成分齿运动(图2),自制蜗轮滚刀装于床头与尾座尖之间,由车床主轴带动做主运动,蜗轮 I plant for processing a copper worm gear shown in Figure 1, due to small modulus (m = 1), a small number of teeth (Z = 26), Y3150E can not be processed, but only in the lathe processing. This method is simple and easy to meet the general accuracy requirements, economical and practical. First, the working principle Tap tap holes can be automatically introduced when the principle of hob rotation to drive the worm wheel rotation, the completion of tooth movements (Figure 2), homemade worm hob mounted on the head and tail tail between the tip by Lathe spindle drive to do the main movement, worm gear
