Study on the Intrinsic Characteristic of Power Split Double Helical Tooth Planetary Transmission System

考虑两级之间的耦合和行星轮位置相角时变性等因素,采用集中参数法,在定坐标系下建立了功率分流人字齿行星传动系统的动力学模型,在此基础上对舰船用功率分流行星齿轮系统的固有特性进行了分析,得到了不同于单级行星传动系统的特有模态特性,为功率分流行星及多级行星传动系统动态设计提供了指导。

Considering the factors of time - variation location phase angle and coupling between the two levels of planet gear and so on, by using lumped - parameter method, the dynamics model of power split double helical tooth planetary transmission system is built under the fixed coordinate system. On this basis, the intrinsic characteristic of power split planetary transmission system used in ships and warships is analyzed, the specific modal characteristic which is different from single stage planetary gear system of is obtained. The guidance for dynamic design of power split planetary and multistage power split planetary transmission system is provided.
