四轴联动数控螺旋锥齿轮铣齿机的齿长曲率修正（4-axis CNC Spiral Bevel Gear Machine Tooth-profile Lengthwise Curvature Modification）
螺旋锥齿轮铣齿机 加工坐标系 轮齿接触分析
2010/12/28
常规机床对螺旋锥齿轮的齿长曲率进行修正时，需从机床上拆装铣刀盘，并重新调整其行程直径，过程繁琐。对此利用国产四轴数控铣齿机，建立铣齿加工坐标系，以及径向刀位、切削滚比变化多项式。用轮齿接触分析（TCA）的方法，以被加工齿面的接触路径、传动误差作为评价目标，研究径向刀位、切削滚比的变化对齿长曲率修正的规律。TCA分析及铣齿实验结果表明，不改变铣刀盘直径，即可实现对齿长曲率的修正，同时可更加灵活地控制...
