一、齿形加工与内啮合副几何尺寸的关系一般内齿轮要插齿,外齿轮可以滚齿或插齿。因此,内啮合可分为:内外齿轮都插齿(以下称双插);内齿插、外齿滚(简称滚插)。在设计中应注意区别刀具和齿轮的参数。例如:滚刀的刀顶高系数为 fg+Cg,标准滚刀 fg=1,Cg=0.25;插齿刀的刀顶高系数为 fu+Cu,标准插齿刀 fu=1,Cu=0.25或0.3;齿轮的齿顶高系数为 f_0,径向间隙为 C_(12)和 C_(21),当 C_(12)=
First, the tooth profile and the internal geometry of the Vice-relationship between the general gear to gear, external gear hobbing or gear-tooth. Therefore, the internal gear can be divided into: internal and external gear are inserted gear (hereinafter referred to as double plug); internal gear, external gear roll (referred to as roll inserted). In the design should pay attention to distinguish the tool and gear parameters. For example, the hob’s top height coefficient is fg + Cg, the standard hob fg = 1, Cg = 0.25; the top height coefficient of the gear shaper is fu + Cu, the standard shaper fu = 1, Cu = 0.25 or 0.3; gear tooth top high coefficient of f_0, the radial clearance of C_ (12) and C_ (21), when C_ (12) =
