摘要

针对齿轮机构在运行中会产生噪声和振动的问题，对非圆齿轮减振特性进行了研究。分析了齿轮中心与圆心的偏差对运动特性和振荡特性的影响。结果表明，由于啮合频率的变化，较大的偏差会导致较小的共振振幅，同时会导致机构附加动载荷的增加。确定了齿轮中心的形状，进而提供了相对较小的共振振幅和最小的附加动态载荷。开发了一种机械装置，可以在没有数控机床的情况下在滚齿机上切削非圆齿轮。

Abstract

Aiming at the problem of noise and vibration in the operation of gear mechanism， the vibration reduction characteristics of non-circular gear are studied. The influence of the deviation between the gear center and the center of the circle on the kinematics and oscillation characteristics is analyzed. The results show that a larger deviation will result in a smaller resonance amplitude due to the change in mesh frequency， and at the same time will lead to a higher additional dynamic load on the mechanism. The shape of the gear center is determined，which provides relatively small resonance amplitudes and minimal additional dynamic loads. A mechanical device that can cut slightly non-circular gears on a hobbing machine without numerical control machine is developed.
