我们加工双切线链轮,采用计算坐标的方法,用端齿分度盘在立铣上铣削齿形,效果较好。现将计算和铣削方法介绍如下: α齿右侧面A和b齿左侧面B,相切于同一个R6圆弧面(图1),两侧面夹角58°。以工件中心O为原点,作平面直角坐标系XOY,使Y轴平行于A面。P点是R6圆弧之中心,它处在节圆上。用φ12立铣刀来分两刀铣削齿形,铣削时取工作台走刀方向与Y轴平行;再用端齿分度盘分齿,依次铣
We process double tangential sprockets, using the method of calculating the coordinates, with the end of the indexing plate milling milling tooth milling, the effect is better. Now the calculation and milling methods are introduced as follows: α right tooth A and b left tooth B face, tangent to the same R6 arcuate face (Figure 1), the angle between both sides of 58 °. The workpiece center O as the origin, for the plane Cartesian coordinate system XOY, the Y-axis parallel to the A surface. Point P is the center of R6 arc, which is on the pitch circle. Use φ12 cutter to split the tooth milling two points, take the table when milling walk along the Y-axis parallel to the direction;
