Research on Contact Spots of Torque Transmission Mechanism with Single Gear Pair

以单齿轮副面齿轮分扭传动机构为研究对象,分析系统中的受力及变形,建立包含承载变形的面齿轮接触轨迹方程。根据赫兹接触理论计算了接触斑点,获得承载变形对面齿轮副接触斑点位置的影响规律。运用Ansys软件对机构中的接触斑点进行仿真分析,理论分析获得的齿面接触斑点与仿真获得的接触斑点分布规律基本一致。

With single gear pair face gear split-torsion transmission mechanism as the research object,the forces and deformations in the system is analyzed,and the contact trajectory equation of the face gear including the load-bearing deformation is established.According to Hertz contact theory,contact spot is calculated to obtain the influence of deformation on the contact spot position of the gear pair in the mechanism.The Ansys software is used to simulate the contact spots in the mechanism.The contact spots on the tooth surface obtained from the theoretical analysis are basically consistent with the contact spots obtained by the simulation.
