非圆齿轮-圆柱齿轮动力学对比仿真研究

Research of the Dynamics Simulation Comparative of Non-circular Gear and Spur Gear

由于非圆齿轮齿廓几何形状复杂以及齿轮重合度的时变性,难以利用理论方法研究其动力学行为,寻求一种简便、可靠的方法来研究其动力学行为具有重要的意义。以一对特定传动比函数的非圆齿轮传动和一对圆柱齿轮传动作为对比实验,基于ADAMS,从角速度、角加速度、啮合力等方面动力学性能与相应的理论计算值进行了对比。该研究为更深入研究非圆齿轮传动和圆柱齿轮传动动力学差异问题,并将圆柱齿轮的研究成果加以修正的应用到非圆齿轮传动领域提供了思路。

Due to the complexity of gear tooth profile and the time--varying feature of gear contact ratio, it is difficult to use existing theoretical methods to study its dynamical behavior. Therefore, it is significant to seek for an easy and reliable new way to study its dynamical behavior. By taking a pair of non--circular gear transmission of a specific transmission ratio function and a pair of cylindrical gear transmission as a contrast experiment, based on ADAMS, the experimental results with the corre- sponding theoretically calculated values from the angular velocity, angular acceleration, meshing force as well as other dynamical behaviors are compared. This study provides a new idea not only for the in- tensive research on the difference between non--circular gear transmission and cylindrical transmis- sion, but also for the application of the modifying achievements of cylindrical gear to the field of non-- circular gear transmission.
