在滚齿加工中,判断是否需要操作工序,应以其对齿轮加工精度有无影响而定。本文论述滚刀对中在滚齿过程中对齿轮的加工精度的影响。一、由滚切原理产生的齿形误差 1.滚切齿轮相当于一对螺旋齿轮的啮合为了便于分析,习惯将滚切过程简化为滚刀的法向齿条与齿轮的平面啮合。按此啮合原理,有两条啮合线相交于节点,并以过节点和齿轮中心的连线为对称轴,因此,工件同一基圆的两侧的渐开线齿廓也是
In the hobbing process, to determine whether the need to operate the process should be based on whether the accuracy of the gear processing may be. This article discusses the effect of hobbing on gear machining accuracy during gear hobbing. First, the hobbing error caused by the hobbing principle 1. Hobbing gear is equivalent to the meshing of a pair of helical gears In order to facilitate the analysis, it is customary to reduce the hobbing process to the normal engagement of the rack with the gear. According to the principle of meshing, there are two meshing lines intersecting at the node, and the connection node between the node and the gear center is the symmetry axis. Therefore, the involute profile on both sides of the same base circle of the workpiece is also
