摘要: 基于2K-H直齿行星齿轮传动的平移-扭转耦合模型,建立了行星齿轮传动系统的振动能量公式,分析得出了行星轮系参数灵敏度与振动能量的关系;以包含4个行星轮的行星轮系为例,在内齿圈固定的工作情况下,对行星齿轮传动的振动动能与振动势能进行了计算。经分析得知,行星齿轮传动的振动能量主要以振动势能为主,从各构件振动能量随振动阶次的变化情况可得出行星齿轮传动参数对特征值的影响规律。Abstract: Based on a torsional-transverse coupling model of a 2K-H spur planetary gear, the equation formula of vibration energy of planetary gear transmission system was derived. The relationship between the parameter sensitivity of the planetary gear and vibration energy was analyzed. Potential energy and kinetic energy of the planetary gear that contains four planet gears were calculated under the operation conditions, in which the ring gear is fixed. The analysis results showed that the vibration energy of the planetary gear is mainly dominated by strain energy. It may safely draw the conclusion that the influence law of the planetary gear parameters on eigenvalues can be obtained from the variety of vibration energy of each component with the different order of vibration.
