摘　　要：行星轮间良好的功率分流行为使得行星机构具有较高的能量传输密度,因此行星轮系在重型直升机传动系统中得到了广泛应用。由于客观存在各种制造误差,无法避免偏载问题,行星机构的功率无法按照理想状态分配,进而影响整个系统的服役寿命和可靠性。基于某型号重型直升机行星减速器的结构特征,构建大型行星轮系的有限元仿真模型,定量分析不同方向销孔位置制造误差对功率分流特性的影响,得出偏载影响机理,为航空领域行星齿轮的公差带设计技术提供理论基础。Planetary gear train is widely used in heavy helicopter drive systems because of the good power shunt behavior between planetary gears,which results in high energy transmission density of planetary mechanisms.However,due to the objective existence of various manufacturing error factors,the problem of offset load can not be avoided,and the power of planetary mechanism can not be distributed according to ideal state,which affects the service life and reliability of the whole system.Based on the structural characteristics of planetary reducer of a heavy helicopter,the finite element simulation model of large planetary gear train is built.The influence mechanism of offset load on power shunt characteristics caused by manufacturing errors of pin holes in different directions is quantitatively analyzed,which provides knowledge reserve for tolerance belt design technology of planetary gears in aerospace field.
