摘要
为了提高零度弧齿锥齿轮的啮合性能,提出了以局部综合法为基础的小轮变性法加工参数设计方法。建立含安装误差的轮齿接触分析模型,通过求解非线性方程组,获得接触迹线和传动误差曲线,基于微分几何计算瞬时接触椭圆长轴。算例结果表明,变性法加工可获得中凸的抛物线型传动误差且幅值控制在较小的范围;轴交角安装误差对啮合性能影响最大,需保证其安装精度。
In order to improve the meshing performance of zero spiral bevel gears,a modified roll method of processing parameter design method based on local synthesis method for pinion is proposed. The tooth contact analysis model including assemble errors is established. The contact path and transmission error curve are obtained by solving the nonlinear equations system. Then,the major axis of instantaneous contact ellipse is calculated based on differential geometry. The numerical example results show that,a middle- convex parabolic transmission error with the amplitude under a smaller range is achieved by using the modified roll method. The shaft angle misalignment has greatest effect on the meshing performance,which need to ensure the installation accuracy.
