摘　　要：通过分析弧齿锥齿轮加工原理及传统机械摇台式弧齿锥齿轮铣齿机的结构和机床运动关系,建立了弧齿锥齿轮铣齿机加工坐标系。采用刀盘主轴进给方式代替传统的整体工件箱部件或摇台部件进给方式,建立了重型弧齿锥齿轮铣齿机三维结构模型。分析了由传统机械摇台式弧齿锥齿轮铣齿机调整参数转变为重型数控弧齿锥齿轮铣齿机调整参数的原理和计算方法,建立了重型弧齿锥齿轮铣齿机的数控加工模型。通过计算实例,得到了重型数控弧齿锥齿轮铣齿机铣齿加工时机床各运动轴的瞬时位置。建立了重型弧齿锥齿轮铣齿机仿真加工机床模型,并进行了仿真加工,仿真结果满足弧齿锥齿轮铣齿机功能性验证要求。The machine machining coordinate system of spiral bevel gear cutting machine was established by analyzing the machining mechanism of the spiral bevel gear and the relationships between the structure and motion of the traditional mechanical spiral bevel gear cutting machine.The 3-D structure model of the heavy duty spiral bevel gear cutting machine was built,using the cutter spindle feed method instead of the traditional workpiece box feed method or the machine cradle feed method so as to increases the machine＇s manufacture efficiency and machining precision, according to the machining characteristic of heavy duty spiral bevel gear. And the numerical control machining model of the heavy duty spiral bevel gear cutting machine was also proposed, by analyzing the shift principle from the traditional mechanical spiral bevel gear cutting machine＇s adjustment parameter to the. heavy duty numerical controls spiral bevel gear cutting machine. Finally, the instantaneous position of the heavy duty numerical control spiral bevel gear cutting machine＇s kinematic axis was obtained through the example computation. The machining machine model of the heavy duty spiral bevel gear machine was built, and the simulation machining was also carried out. The functional verification requiremem of spiral bevel gear machine can be satisfied by the simulation results.
