摘　　要：弧齿非圆形锥齿轮的各个齿形参数不同,加工方法复杂。为解决其切削加工难题,基于圆锥齿轮的啮合原理,提出了一种弧齿非圆锥齿轮的数控铣削加工方法。根据非圆锥齿轮的节曲线数据和齿轮啮合理论,推导出加工参数及成型盘铣刀和被切轮坯的瞬时位置公式,并用Matlab数值法求解出一系列刀具和轮坯的位置坐标,计算结果作为数控加工程序的控制参数,可用五轴NC机床加工弧齿非圆锥齿轮。加工实例说明该方法正确,可以提高加工精度和加工效率。Non-circular spiral bevel gears have different tooth profile parameters lead to complex machining process.In order to solve the problem,a NC machining milling method based on meshing principle for non-circular bevel gears is presented.According to the pitch curve data of non-bevel gears and the meshing theory,the formulas of disc milling cutter and the gear billets positions are deduced.And with MATLAB numerical method,the machining parameters and a series of instantaneous position coordinates of tool and gear billet are calculated.In accordance with these parameters value and result,the Non-circular Spiral Bevel Gear can be machined with five-axis NC machine tools.The machining example shows that the method is correct,and with the milling process method accuracy and efficiency will be improved.
