大模数多头滚刀径向铲齿时,侧刃后角不超过2°～4°。这种滚刀的使用经验证明,滚切蜗轮时,工件和滚刀齿侧后面产生摩擦。本文想根据蜗轮的几何参数及加工用量,求出计算多头滚刀侧刃后角的最简单方法,同时,按计算出来的侧刃后角值确定正确制造滚 Larger modulus hob hob radial radial teeth, the side after the angle does not exceed 2 ° ~ 4 °. Experience with this type of hob shows that when the worm gear is hobbed, the workpiece and hob behind produce flaws. In this paper, according to the geometric parameters of the worm wheel and the processing volume, the simplest method of calculating the relief angle of the long side cutter is obtained. At the same time, the correct manufacture of the roll
