摘要
提出了一种面齿轮齿面的拓扑修形设计方法来提高齿面的接触性能。首先,通过渐开线圆柱齿轮共轭出面齿轮齿面,以该齿面为基准面,借助二阶、四阶多项式构建ease-off差齿面。然后,通过解析ease-off差齿面的拓扑结构,获取了接触路径与几何传动误差等轮齿啮合特性。最后,通过预置二阶、四阶传动误差曲线、接触路径和接触区等齿面啮合性能参数来设计ease-off差齿面,对叠加差齿面后的修形齿面进行轮齿接触分析和有限元啮合仿真分析。结果表明,所得的齿面传动误差、接触路径与预设的传动误差、接触路径基本吻合。通过对2种修形方法的对比分析发现,四阶多项式拓扑修形齿面的啮合性能要优于二阶修形齿面,为模具法面齿轮齿面的修形设计提供了参考。
A topological modification design method of the tooth surface of face gear was proposed to improve the contact performance.Firstly,the completely conjugated tooth surface of the face gear was derived based on the flank of the involute cylindrical gear.Taking this tooth surface as the datum,the ease-off surface was constructed by using second-order and fourth-order polynomials.Then,according to the analysis results of the ease-off surface topological structure,the meshing characteristics of gear teeth such as contact path and geometric transmission error were obtained.Finally,the ease-off surface was designed by presetting the tooth surface meshing performance parameters such as the second-order and fourth-order transmission error curve,contact path,and contact pattern.The tooth contact analysis and finite element meshing simulation analysis were carried out on the modified tooth surface after the superposition of the ease-off surface.The results show that the transmission error and contact path were consistent with the predesigned transmission error and contact path.According to the comparative analysis of the two modification methods,it is found that the meshing performance of the modification tooth surface with fourth-order polynomial topological structure is better than that with second-order one,which provides a reference for topological modification design of the die tooth surface of face gear.
