双压力角非对称齿轮轮齿接触分析（Tooth Contact Analysis for Unsymmetric Gear with Double Pressure Angles）
齿轮传动 轮齿接触分析 双压力角
2010/12/28
对双压力角非对称齿轮在修形和误差条件下的啮合过程进行了全面推导，并编制了轮齿接触分析(TCA)计算机数值仿真程序。通过对非对称齿轮与标准对称齿轮进行仿真计算，得出双鼓形非对称齿轮在有安装误差的情况下，接触迹的偏移量比标准对称齿轮小，传动误差的幅值比标准对称齿轮有明显降低，因此具有良好的传动平稳性和较高的承载能力。
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...
