摘　　要：等速对转行星齿轮传动系统是对转风扇开式转子发动机的关键技术。与齿轮驱动单级风扇(GTF)发动机的行星齿轮传动系统相比较,该系统的结构更为复杂,工作条件更恶劣。本文以对转风扇开式转子发动机齿轮传动系统概念设计为基础,开展了行星齿轮传动系统初步设计、齿轮疲劳强度分析、行星轴承寿命分析和传动系统润滑设计技术研究,为开式转子发动机的发展提供参考。As the key technology of the open rotor engine with counter-rotating fans, the planetary gear system with the same counter-rotating speeds owns more complicated configuration and bears poorer working environment compared with the single fan of geared turbofan engine. Based on the concept design of gear driven system for the open rotor engine with counter-rotating fans, the preliminary design of planetary gear system, gear tooth strength analysis, planetary bearing life analysis and lubrication design technology research were accomplished in this paper, which contribute to the development and experience accumulation of the open rotor engine.
