大模数齿轮用历来的剃齿刀加工时,因加工精度低,刀具制造困难,故在精加工时很少用剃齿方法;一般用精滚;精滚能提高齿距精度,但齿形精度和齿面光洁度较差。作者研制成功一种适宜大模数齿轮精加工的滚剃刀,它具有剃齿和滚齿两方面的优点。滚剃刀可用简单的装置制造,并容易保证滚刀精度,不改变工装夹,即可在滚齿机上加工出高精度的齿轮。图1是模数16的滚剃刀外观图,很多不铲磨、无后角的刀刃集中在蜗杆螺旋面上,其中 Large modulus gear with the usual shaving cutter processing, due to low machining accuracy, difficult to manufacture tools, it is rarely used in finishing shaving method; generally with precision roller; precision roller pitch accuracy can be improved, but the tooth Accuracy and tooth surface finish is poor. The author has successfully developed a large modulus gear finishing roller shave, it has the advantages of both shaving and hobbing. Roller razors can be made with simple equipment and easy to ensure hob accuracy, without changing the fixture, you can gear hobbing machine to produce high-precision gear. Figure 1 is a modulo 16 roll razor appearance, many do not shovel grinding, no corner of the blade edge concentrated on the worm screw surface, which
