为了提高剃刀寿命,在剃齿前滚制工件时,工件齿形应加以特殊修正。在近代机器制造中,这种特殊修正是借用加厚齿顶的滚刀滚出带有根切的齿轮,使刺刀齿顶不进行切削。同时由于滚刀有齿腹,使齿轮齿顶得到修正,这样就可避免剃齿时,因产生的毛剌而损坏剃刀。 一般工厂多设计如图1所示 In order to increase the lifespan of the razor, the workpiece profile should be specially modified when rolling the workpiece before shaving. In modern machine building, this special modification borrows the thickening of the top of the hob roll out of gear with a root cut, so that the bayonet top of the tooth is not cutting. At the same time as the hob has a belly, so that the top of the gear tooth is modified, so you can avoid shaving, the hair damage caused by razor damage. General factory design as shown in Figure 1
