Abstract  

For the problems of vibration and impact of the planetavy gear reducer with small tooh difference anew type of metal rubber composite gear was proposed, The effects of varying mesh stiffness and damping, gear error excitation, bearing support stiffness and damping, drive shaft torsional rigidity and damping, metal rubber radial support stiffness and damping were considered. A bending-torsional coupled and six-freedom nonlinear vibration mode was established based on the lumped-mass method. The dynamic equations was solved by using the PECE Adams method with variable order, and the vibration charactetistics of composite gear pair were studied. Then  a experiment was conducted  to get vibration responses of the metal gear pair and composite gear pair.  Results showed that the wheel hub had a smaller vibration displacement and vibration velocity compared to the gear ring. The wheel hub also got smaller torsional vibration angular displacement and torsional vibration angular velocity. The vibration stability of composite gear was better than metal gear pair. The simulaton  results accorded with the experimental results.

金属橡胶复合齿轮副振动特性分析及实验

针对少齿差行星减速器传动过程中存在的振动冲击问题,提出新型的金属橡胶复合齿轮副,综合考虑时变啮合刚度、啮合阻尼、齿轮误差激励、轴承支撑刚度、支撑阻尼、传动轴扭转刚度、扭转阻尼及金属橡胶径向支撑刚度和支撑阻尼等因素,采用集中质量法建立弯-扭耦合的6自由度非线性振动模型|采用可变阶次的多步Adams PECE法对动力学方程进行求解,研究复合齿轮副的振动特性|实验验证金属齿轮副和复合齿轮副的振动响应.结果表明,复合齿轮齿圈的振动位移和振动速度最大,经过金属橡胶弹性体后,轮毂的振动位移和振动速度均有明显的减小|同样,轮毂的扭转振动角位移和扭转振动角速度较齿圈有一定的衰减|复合齿轮副振动平稳性要优于金属齿轮副|仿真结果和实验结果基本一致.
