摘　　要：介绍了一种用端面铣削法展成粗切摆线锥齿轮小轮的方法。根据展成加工中端面铣削法和端面滚切法的特点建立了统一的数学模型,采用端面铣削法数控加工时各轴运动的表达式实现了高阶泰勒展开,并对各项式系数进行了计算。以减小齿面偏差为目标,基于对运动多项式系数的优化建立了目标函数,编制了优化计算程序。基于上述理论基础,引入算例对粗精切齿面偏差展开了理论分析,最后完成了齿轮的虚拟加工。结果表明了展成粗切加工摆线锥齿轮理论的可行性和正确性。A face milling method to rough processing the pinion of cycloid bevel gears is introduced. On the basis of the difference between face-milling and face-hobbing,the universal mathematical model is established firstly,the high order Taylor expansion of each NC axis in the process of face milling is finished and the corresponding coefficients are calculated. Aiming to reduce the deviation between the roughing surface and the finishing surface,an objective function is structured to optimize all of the coefficients and the related program is written out. A pair of gears is used to analyze the deviation from a theoretical point of view. Finally,the simulation processing is carried out,the feasibility and the correctness of the proposed method are verified.
