摘　　要：为了深入了解钢质行星齿轮传动系统引入塑料齿轮后的振动特性,建立钢/塑齿轮组合行星传动的动力学分析模型和试验模型,对SNS、SSS、SSN和NSS四种钢/塑齿轮组合行星传动的振动特性进行理论分析与试验研究,分析组合方式对行星传动振动特性的影响。数值仿真与试验研究结果表明:塑料齿轮的引入对行星齿轮传动的振动特性影响很大,显著地减小了太阳轮与行星轮和内齿圈与行星轮的啮合动载荷;有效地抑制了行星齿轮传动的齿轮啮合频带振动和高频带振动;组合方式对行星齿轮传动的振动特性影响显著,合理地采用钢/塑齿轮组合行星传动结构可以极大地降低啮合动载荷,从而有效地抑制传动系统的振动和噪声。The key issue is how substituting plastic gears for steel ones affects planetary gear dynamic behavior. A torsional dynamic model of planetary gears is presented with time-varying meshing stiffness, damping, error excitation and gear compliance considered. The vibration teat rig for planetary geared system is also constructed. The dynamic behavior of the planetary geared systems composed of S（steel）/N（plastic）/S（steel）, SSS, SSN and NSS （sun/planet/ring gear） are investigated. Numerical and experimental results demonstrate that plastic gears can dramatically change the dynamic behavior of planetary geared systems. The numerical results on the planetary geared system indicate that plastic gears can reduce dynamic loads on sun-planet and ring-planet gear mesh markedly. The experimental results also show that substituting plastic gears for steel ones can effectively reduce the high and low frequency vibrations for planetary geared systems.
