我们经常碰到各种标准的和非标准的渐开线短齿齿轮,齿接手,花键轴、套,内齿磨擦片等零件的加工。加工内、外渐开线短齿,可用两种方法:一种是刀杆移动法;另一种是分齿移动法。一、刀杆移动法用滚刀加工短齿齿轮时,可看成齿条与短齿齿轮相啮合。由于两者的齿高系数不同,设刀具的齿顶高为h＇刀,被切齿轮的齿根高为h″齿,在滚切齿轮时,则刀具的节线m-m We often encounter a variety of standard and non-standard involute gear, tooth clutch, spline shaft, sleeve, internal friction plate and other parts of the processing. Processing inside and outside involute short teeth, available in two ways: one is the arbor moving method; the other is the sub-tooth moving method. First, the knife movement method Hob with short gear, it can be seen as a rack and short gear meshing. As the tooth height coefficient of the two different, set the tool tip height h ’knife was cut gear root height h "tooth, the hobbing gear, then the knuckle m-m
