摘　　要：从齿轮时变啮合刚度出发,建立了单级2K-H渐开线行星齿轮传动的集中质量参数型振动模型,以行星架作为参考坐标,将齿轮啮合的刚度近似成时变分段线性的弹簧刚度,采用模态叠加的原理,通过系统在刚度变化时的速度以及位移的连续性条件,在时域范围内模拟系统的振动过程。分析了不同齿数齿轮对啮合力的影响,最后得出:在2K-H渐开线行星齿轮传动中,若太阳轮与内齿圈均为行星轮个数的整数倍时,行星轮的均载效果好;太阳轮与内齿圈的齿数不为行星轮个数的整数倍时,行星轮之间出现偏载;系统有数个与初始刚度相关的稳定点的结论。Based on time- varying mesh stiffness simplified as time- varying linear spring, the paper gave a 2K- H lumped- parameter planetary gear set model. Through analysis effects of different gear numbers on engaging force, conclusion was made that in 2K - H planetary gear cycling, if the numbers of the sun gear and the ring gear are integral multiple than those of the planetary gear, the effect is good. If not, there will be partial load between planetary gears. So the system has several stability paints related to initial stiffness.
