为了解钢质行星齿轮传动系统引入塑料齿轮后的振动特性,建立了钢/塑齿轮组合行星传动的动力学分析模型和实验模型,对4种钢/塑齿轮组合行星传动系统的振动特性进行了理论分析与实验研究,分析了组合方式对行星传动振动特性的影响.数值仿真与实验研究结果表明:塑料齿轮的引入对行星齿轮传动的振动特性影响很大,显著减小了太阳轮-行星轮和内齿圈-行星轮的啮合动载荷,有效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,从而显著地降低传动系统的振动和噪声.
In order to reveal the vibration characteristics of the steel planetary transmission system with plastic gears substituting for the steel ones, this paper establishes the dynamic and experimental models of the transmission sys- tem and performs both theoretical analyses and experimental investigation of the vibration characteristics of four transmission systems in different steel/plastic compound modes. Then, the effect of the compound mode on the vi- bration characteristics is discussed. Numerical and experimental results demonstrate that plastic gears dramatically change the vibration characteristics of planetary transmission systems, greatly reduce the dynamic mesh loads on the sun-planet and ring-planet gears, and effectively suppress the gear-meshing sideband vibration and the high-fre- quency vibration of the transmission system. Moreover, it is indicated that the compound mode affects the vibration characteristics significantly, and that a reasonable steel/plastic gear compound may greatly reduce the dynamic mesh load and further reduce the vibration as well as the noise of the transmission system.
