在工厂常常会遇到短齿齿轮的加工问题。由于一般工厂很少备有非标短齿插齿刀,如果到工具厂去定做,时间慢,而且不经济。对此,我们应用标准插刀来改制。经实践试用,效果很好,现介绍如下。一、插削短齿内渐开线花键如果用标准插齿刀来加工短齿内渐开线花键,就会出现全齿高能满足尺寸,但齿厚有增厚的现象。为了使加工齿轮时,既能保证齿厚,又不致将牙齿切得过深,我们把插齿刀的齿顶圆磨小,就能达到此要求。下面来分析改磨插齿刀顶圆直径的计算公式。 (1)设花键和插齿刀的模数和齿形角为m、a_(?),齿数为z_1、z_0,变位系数为x_1、x_0。花键齿根圆直径为 In the factory often encounter short tooth gear processing problems. Due to the general factory rarely equipped with non-standard short gear gear shaper, if to the tool factory to customize, time is slow, and not economical. In this regard, we use a standard knife to restructuring. Practice by trial, the effect is very good, are introduced as follows. First, insert the short involute involute spline If you use a standard gear shaper to process short involute splines, there will be full-tooth high-energy to meet the size, but the thickening of tooth thickness phenomenon. In order to make the gear, both to ensure tooth thickness, but also will not cut the teeth too deep, we have the gear tooth tip round grinding small, you can meet this requirement. The following analysis to change the diameter of the cutter tip diameter calculation formula. (1) Set the modulus and tooth profile angle of spline and gear shaper m, a_ (?), Number of teeth z_1, z_0, displacement coefficient x_1, x_0. Spline root circle diameter
