给出了点接触面齿轮传动的齿面方程和啮合接触方程,编制了相应的计算机程序,对接触点轨迹进行了仿真;分析了主要传动参数对接触点位置的影响,获得的一些规律可供在工程应用中参考。即刀具和小齿轮齿数差、齿数比、模数对啮合接触点有很大影响:当齿数差由小变大,齿数比从大变小或当模数从大变小时,接触点向面齿轮的小端移动 The tooth surface equation and meshing contact equation of point contact gear transmission are given. The corresponding computer program is compiled and the contact point trajectory is simulated. The influence of the main transmission parameters on the contact point position is analyzed. Some rules obtained are available In engineering application reference. That is, the difference between the number of teeth of the cutter and the pinion, the ratio of the teeth, and the modulus have a great influence on the meshing contact point: when the tooth number difference changes from small to large, the gear ratio decreases from large to small or the modulus changes from large to small, The little end moves
