摘要

基于集中参数,建立了双输入圆柱齿轮分流传动系统的弯扭耦合动力学模型,模型中考虑了各齿轮副间的齿侧间隙、时变啮合刚度、啮合阻尼等因素。采用四阶龙格-库塔法,求解系统动力学方程,获得了系统的动力学均载系数。分析了齿侧间隙对均载系数的影响,获得了齿侧间隙对分流级、并车级均载系数的变化规律。研究结果表明:分流级均载系数随分流级单分支齿侧间隙增加而增大,随分流级双分支齿侧间隙增加而减小;分流级单分支、双分支齿侧间隙对并车级均载系数影响较小;并车级均载随并车级单分支齿侧间隙增加而增大,随并车级双分支齿侧间隙增加而减小;并车级单分支、双分支齿侧间隙对分流级均载系数影响较小;动载系数随双分支齿侧间隙的增加而增大。

Abstract

Based on the theory of the concentrated parameter,a dynamic analysis model was established for a 2-input cylindrical gear split-torque transmission system, in which the time-varying mesh stiffness, backlashes and damping were considered. Through solving of dynamic equation by the fourth Runge-Kutta method, the dynamic load sharing coefficients of the system were acquired. The results show that the load sharing coefficient of the split-torque stages increases with the backlash of single branch in split-torque stages, and decreases with increasing of the backlash of dual branch in split-torque stages; the backlash of single and dual branch in split-torque stages has very small impact on the load sharing coefficient of synthesized torque stages. The load sharing coefficient of the synthesized torque stages increases with the backlash of single branch in synthesized torque stages, and decreases with increasing of dual branch in synthesized torque stages; the backlash of single and dual branch in synthesized torque stages has very small impact on the load sharing coefficient of split-torque stages; The dynamic load coefficient increases with the backlash of dual branch.
