摘　　要：为了获得高啮合稳定性的面齿轮传动机构,提出了一种螺旋齿面齿轮计算机辅助三维拓扑修形设计,获得点接触面齿轮啮合副以避免发生边缘接触的方法。首先建立接触路径修形设计的数学模型,采用虚拟插齿面齿轮原理,通过预先设计的传动误差函数实现了沿期望接触路径的齿面齿廓修形;然后利用计算机辅助设计技术构建沿接触线修形的数学模型,进行了沿接触线方向修形设计;通过修形量的叠加,重构了三维拓扑修形齿面,最终获得点接触双凸型面齿轮传动。最后以两种不同修形参数的螺旋齿面齿轮为例进行了轮齿接触分析(tooth contact analysis,TCA)。结果表明:设计参数与仿真结果高度一致,验证了计算机辅助修形设计方法的合理性。In order to obtain a face gear transmission mechanism with the high meshing stability,the method of 3D topological modification method with computer aided design technology was proposed in the spiroid face gear.The gear meshing pair with point contact surface can be gotten by calculated,it avoided the edge contact phenomenon.Firstly,the modification model of contact path was established by presetting a transmission error function along the desired contact path,the spiroid face gear was generated by the principle of slotting.Then the modification model of contact line was constructed by Computer aided design technology,it was carried out on the same spiroid face gear.The tooth surface based on the 3D topological modification was reconstructed through the superposition of the two modifications amount,it achieved point contact in the double convex face gear transmission.Finally,tooth contact analysis(TCA) of the spiroid face gear with two different design parameters was accomplished.The result shows that the design parameters are highly consistent with the simulation results,and the rationality of the topological modification method with computer aided design technology is verified.
