在YB6020花键铣床上加工8级精度的圆柱螺旋齿轮,不仅扩大了设备利用率,而且解决了在普通滚齿机床上无法加工的细长齿轮轴问题(见“电力机械”1985年第3期)。但是计算分齿挂轮的时间一次要花费几小时甚至几天。本文介绍的微机计算程序,使计算时间缩短到一次只需要几分钟,既迅速又准确。已知在花键铣床上滚削圆柱螺旋齿轮时滚刀沿齿长进给运动传动链换置公式为 The machining of 8-level precision cylindrical helical gears on the YB6020 spline milling machine not only increases equipment utilization but also solves the problem of an elongated gear shaft that can not be machined on conventional hobbing machines (see “Electric Machinery”, Issue 3, 1985). However, it takes several hours or even days to calculate the timing of the pinning gear. This article describes the computer program to reduce the calculation time to only need a few minutes, both quickly and accurately. It is known that when hobbing a cylindrical helical gear on a spline milling machine, the hob is fed along the gear length and the transmission chain is substituted
