摘　　要：基于成形原理加工齿轮廓形的盘铣刀是生产大型风电传动齿轮的必备刀具。然而,受加工原理误差影响,传统齿轮盘铣刀只能针对特定模数和齿数齿轮进行加工,刀具通用性差。传统刀具廓形不能够保证被加工齿轮的加工精度与使用寿命,无法最大程度发挥成形铣削的原理优势。基于此建立了齿轮渐开线实际廓形曲线数学模型,分析了共轭齿条顶角相对运动轨迹,建立了齿根过渡曲线方程,依据齿根过渡圆弧空间相对位置,重构了不同形式齿廓曲线的设计方式;基于逆向投影法,以被加工齿轮的各项参数为变量,建立了刀片刃形曲线数学模型,根据刀片空间包络原理,重构了可转位齿轮盘铣刀廓形曲线设计方式;进行了齿轮齿廓及刀片刃形曲线数值分析,研究了大型风电传动齿轮齿廓曲线以及可转位齿轮盘铣刀刀片刃形曲线的主要形式,研究结果为大型齿轮廓形成型加工提供技术支持。The gear disk milling tool based on the forming principle is the necessary tool for producing large-scale wind power transmission gears.However,due to the influence of the machining principle error,the traditional gear milling tool can only process specific types of gears,and the versatility of the cutter is poor.The traditional tool profile cannot guarantee the machining accuracy and service life of the gear to be machined,and cannot maximize the principle advantages of form milling.In this paper,the mathematical model of the actual profile curve of the gear involute is established.Based on the relative motion track of the top angle of the conjugate rack,the equation of the tooth root transition curve is established.According to the relative position of the tooth root transition arc space,the design methods of different forms of tooth profile curves are reconstructed.Based on the inverse projection method,the numerical model of the blade edge curve is established with the parameters of the gear to be machined as variables.According to the principle of the blade space envelope,the design method of the profile curve of the indexable gear disk milling cutter is reconstructed.The numerical analysis of gear tooth profile and blade profile curve is carried out,and the main forms of large wind power transmission gear tooth profile curve and indexable gear disk milling tool edge profile curve are studied.
