摘　　要：针对摆线齿准双曲面齿轮在空挡运行时发出尖啸声并伴有严重磨损的问题,通过动力学仿真分析的方法,对正车、倒车、空挡后退、空挡前行这几种工况下的齿轮的传动误差、角加速度的时域和频域图,以及正车和倒车在不同负载和转速下的角加速度和噪声的变化进行分析。研究结果表明:在正车工况下,也即是小轮的凹面驱动大轮的凸面的情况下,摆线齿准双曲面齿轮系统的噪声低,所受负载小,啮合动态性能最好;空挡时动态啮合性能较差,对齿轮损害较大。本文研究可为面向综合啮合性能的摆线齿准双曲面齿轮的设计提供依据。For the scream noise and the severe wear issues of the cycloid tooth hypoid gears in neutral running, this project studied the gear transmission error, temporal and spectral characteristics of the angular acceleration with conditions of advancing, retreating or hang gap using dynamics simulation, as well as the analysis of the acceleration, and noise under different load and speed. The results show that the meshing noise and the contact pressure of the cycloid hypoid gears are smaller, and the meshing performance is optimal in driving forward state. However, the dynamic performance is poor at hand gap state. The data from these studies provide some design basis of the cycloid hypoid gears.
