任意齿形齿轮数控加工理论与计算机模拟研究

As any form profile gear numerical control machining theory and computer simulate study

以计算机数控 (CNC)系统代替普通滚齿机中的机械传动链 ,建立了一种新型的滚齿机机构 .依据此机构 ,建立了统一的齿轮加工数学模型 ;推证了机构的运动转换矩阵和相关的运动方程 ,并在计算机上实现了齿轮模拟加工 ;通过调整滚切运动 ,可以实现任意设计的齿形及齿向 ;通过对齿轮加工误差计算机数值仿真 ,得到了一系列有价值的结论 .

This paper presents a new type of mechanism scheme for hobbing machine. By means of adjusting motion, gear shape modification can be realized with common hob, and the tooth modification curves of surfaces can be determined as any form. It has obtained a series of valuable conclusion by gear machining error with the computer simulation.
