数控改造滚齿机加工鼓形齿轮

NC Reconstrucing Gear Hobbing Machine for Machining Drum Gear

通过实例加工,在保留普通滚齿机原展成传动链的基础上,数控改造滚齿机,控制滚齿机的垂直丝杠和水平丝杠,进行呈圆弧齿向的鼓形齿轮加工,同时可实现圆弧齿向的齿轮倒角加工,并叙述了数控加工所需编程参数的转换计算与公式推导,还对改变数控系统脉冲当量和加工运行速度的控制阐述了其理论根据和成因,介绍了实际改造中的具体解决措施。

Based on the primary generating messenger chain,the drum gear having circular teeth can be machined by a NC reconstructing gear hobbing machine whose vertical and horizontal screw have been controlled and chamfer angles are machined at the same time.The conversion computation of program parameters is expatiated and the theory basis to change equivalent impulse and machining speed is analyzed.
