插齿刀是一种带有某些切削角度的变位齿轮,当被加工齿轮的参数确定以后,如果插齿刀的变位系数和齿数选择得正确,即可避免被加工齿轮产生根切顶切和过渡曲线干涉,也可避免插齿刀齿顶变尖,某种型式某个模数的插齿刀,它的齿数基本上是可定值,因此,剩下的问题是正确选择插齿刀的变位系数是插齿刀设计上最重要的一环,我们知道,当插齿刀选用较大的正变位系数以后,可以增加插齿刀的刃磨次数,但是一方面随着变位系数的增加,插齿刀齿顶将变尖,它降低了齿顶强度,加快刀具的磨损,降低耐用度,另方面用变位系数 Gear shaper cutter is a kind of displacement gear with some cutting angle, when the processed gear parameters are determined, if the gear shaper cutter displacement coefficient and the number of teeth is selected correctly, you can avoid the gear to be processed root cut Cut and transition curve interference, but also to avoid the shaper tip tooth tip sharpening, a certain type of a fixed modulus gear shaper cutter, the number of teeth is basically a fixed value, so the remaining problem is the correct choice of gear teeth Knife displacement coefficient is the most important part of gear shaper design, we know that when the gear shaper larger positive displacement coefficient, you can increase shaper sharpening sharpening times, but on the one hand with variable As the bit coefficient increases, the tooth tip of the gear cutter will become pointed, which reduces the strength of the tooth tip, accelerates the wear of the cutter and reduces the durability. On the other hand,
