摘要
为研究行星齿轮传动系统在不同工作模式下的固有特性,采用集中参数法建立了2K-H型直齿行星齿轮传动系统纯扭转动力学模型,借助啮合副间的相对位移分析,推导出系统振动微分方程,对传动系统在无中心构件固定和内齿圈固定两种工作模式下的模态振型进行求解,并对各阶振型归一化处理,利用振型图揭示了系统存在两种振动模式。结果表明:两种工作模式下行星齿轮传动系统均存在扭转振动模式和行星轮振动模式。
In order to study the nature characteristics of the planetary gear transmission system under different working modes,a pure torsional dynamic model of the 2K-H spur planetary gear transmission system is established based on the lumped parameter method.The vibration differential equation of the system is deduced.The modal vibration modes in the two working modes of fixed and internal ring gear are solved,and the vibration modes are normalized,and the vibration modes of the system are revealed through the vibration mode diagram.The results show that the torsional vibration mode and the planetary gear vibration mode exist in the planetary gear transmission system in both working modes.
