一、切削方法的此较蜗轮滚齿,常用径向和切向两种进刀方法。从生产率讲,径向进刀高于切向进刀;从保证质量讲,切向进刀又比径向进刀为佳。现将这两种方法对质量的影响比较于下。(1)加工中心距A_0: 多头蜗轮大都用于不可调节的蜗轮副中作动力传动,故其加工中心距A_0直接影响装配后的工作质量。径向进刀更换工件时,刀具必须沿径向退出,致使A_0 First, the cutting method of worm gear hobbing, commonly used radial and tangential two feed method. Speaking from the productivity, the radial feed is higher than the tangential feed; Speaking of quality assurance, tangential feed is better than radial feed. Now the impact of these two methods on the quality of the next. (1) machining center distance A_0: long worm gear is mostly used for non-adjustable worm gear for power transmission, so the machining center distance A_0 directly affect the quality of work after assembly. Radial infeed To change a workpiece, the tool must exit radially so that A_0
