摘要
为了研究滑动摩擦和相位调谐对齿轮中心双流传动动力学的影响,建立了考虑时变啮合刚度、啮合阻尼、齿面摩擦、啮合相位、支承刚度及支承阻尼的齿轮中心双流传动系统扭转-横向振动耦合模型.通过对齿轮副啮合过程的分析,推导了系统中与摩擦有关的计算公式,并采用数值仿真法研究了滑动摩擦、相位调谐对齿轮动态传动误差和支承动载荷的影响.研究结果表明:滑动摩擦对齿轮支承动载荷影响很大,采用相位调谐可有效地降低系统的动态传动误差及中心轮的支承动载荷.
In order to reveal the effects of sliding friction and phase tuning on the dynamics of the two-path and load-share sun-geared system, a model describing the coupling of torsional and transverse vibrations of the system is developed, with the parameters such as the time-varying meshing stiffness, the meshing damping, the sliding friction, the meshing phase, the bearing stiffness and the bearing damping being considered. By analyzing the meshing process of the spur gear pair, some expressions of the sliding friction are deduced. Moreover, the effects of the slid- ing friction and the phase tuning on the dynamic transmission error of the system and the dynamic bearing load are investigated by performing a numerical simulation. The results show that the sliding friction greatly influences the dynamic bearing load, and that the phase tuning technique effectively reduces the dynamic transmission error of the system and the dynamic bearing load on the sun gear.
