【摘要】：以干摩擦阻尼环对高速大功率密度齿轮传动系统减振特性的影响为研究对象,在考虑干摩擦阻尼环减振作用、轮齿时变啮合刚度、啮合传动误差的基础上,建立干摩擦阻尼环齿轮传动系统的弯扭轴耦合多体动力学模型。设计一套输入最高转速为36 000 r/min、油润滑的齿轮传动系统干摩擦阻尼环减振试验系统,并验证了动力学模型的有效性。研究干摩擦阻尼环结构参数对齿轮传动系统减振特性的影响。结果表明:针对高速大功率密度齿轮传动系统,干摩擦阻尼环具有良好的减振特性,降幅比可以达到20%;通过优化阻尼环结构参数如外圆直径(阻尼环与轮缘间的过盈量)、厚度、宽度等可使齿轮传动系统获得最优减振效果。
[Abstract]:The effect of dry friction damping ring on the damping characteristics of high speed and high power density gear transmission system is studied. Considering the damping effect of dry friction damping ring, the time-varying meshing stiffness of gear teeth and the meshing transmission error are considered. A multi-body dynamic model of bending and torsional shaft coupling for dry friction damping ring gear transmission system is established. A test system for damping vibration of dry friction damping ring of gear transmission system with oil lubrication was designed and the validity of the dynamic model was verified by the design of an oil lubricated gear transmission system with a maximum input speed of 36000 r / min. The effect of structural parameters of dry friction damping ring on vibration absorption characteristics of gear transmission system is studied. The results show that the dry friction damping ring has a good damping characteristic for high speed and high power density gear transmission system, and the ratio of reduction can reach 20. By optimizing the structural parameters of the damping ring such as the diameter of the outer circle (the interference between the damping ring and the flange), the thickness of the damping ring is obtained. The width and so on can make the gear transmission system obtain the optimum vibration absorption effect.
