摘　　要：行星齿轮传动系统作为齿轮驱动风扇(Geared Turbofan,GTF)发动机的关键部件,其传动功率大、空间结构紧凑、工作条件恶劣。为突破该部件设计关键技术,并为国内GTF发动机结构设计积累经验,在GTF发动机齿轮传动系统概念设计的基础上,开展了其初步设计,对齿轮进行疲劳强度分析;采用齿轮宏观参数优化和微观修形设计方法,提高齿轮承载能力,减小传递误差,改善齿轮接触区应力分布,提高齿轮传动系统的运动平稳性。As the key technology of the Geared Turbofan（GTF） engine,the planetary gear system carries higher power.It bears poor working environment and compact space.In order to break through the key technology and accumulate structural design experience of GTF engine,the preliminary design of planetary gear system and gear tooth strength analysis were accomplished based on the concept design of gear-driven system for GTF engine.The macro and micro geometry optimization design method were employed to improve the load capacity of gears,reduce the transmission error,modify the gear contact area and improve smooth operation.
