摘　　要：行星齿轮传动因具有较大的传动比和较高的传动效率而被广泛应用于机械传动系统中。在行星齿轮箱中,太阳轮通常被设置为浮动的,以平衡各行星齿轮之间的负载。但是,太阳轮的浮动设置将导致啮合过程中的压力角、重合度和啮合相位的变化。在以前的研究中,这些参数被近似为常数。为了研究动态参数对行星齿轮箱在不同工况下振动响应的影响,建立了行星齿轮箱集总参数模型,该模型包含时变压力角、时变重合度和时变啮合相位。基于该模型,分析了太阳轮的振动机理,并与恒定参数模型进行比较,揭示了由这些动态参数引起的相位调制规律。通过比较不同负载和转速下的动态响应,研究了不同工况条件下的相位调制。Planetary gearboxes are widely used in mechanical transmission systems due to their large transmission ratio and high transmission efficiency.In a planetary gearbox,the sun gear is usually set to float to balance the sharing of loads among planet gears.However,this floating set will result in the variation of pres⁃sure angle,overlap ratio and meshing phase in the meshing progress.In the previous studies,these parameters were reduced to constant.To study the influence of the dynamic parameters on the vibration response of plane⁃tary gearboxes under different operating conditions,a new lumped parameter model containing the time-varying pressure angle,time-varying overlap ratio and time-varying meshing phase is established.Based on this mod⁃el,the vibration response mechanism of the sun gear is analyzed.Moreover,the comparison with the previous model is made and the rule of phase modulation caused by these dynamic parameters is revealed.By comparing the dynamic responses under different loads and rotation speeds,the phase modulation is studied in detail.
