摘　　要：针对直升机共轴输出的要求,提出了一种实现共轴输出的封闭差动行星传动机构,该构型由定轴轮系和差动行星轮系构成,同时给出了该构型传动比条件、同心条件、邻接条件、装配条件等齿数匹配约束条件;研究了该构型的各个主要部件的受力情况。采用Romax软件和AGMA标准对构型的设计进行了仿真和强度验证。研究结果表明,该构型能够在较小的尺寸下,传递较大的功率,实现共轴输出的要求。According to the requirements of coaxial output of helicopters, a transmission configuration of coaxial output encased dif- ferential planetary is presented. This configuration is composed of ordinary gear train and differential gear train. The constraint condi- tions of tooth number matching such as the transmission ratio condition, concentricity condition, adjacency condition and assembly condition are also presented. Attention is paid to the load on the main component of the configuration. Simulation and strength verifi- cation of scheme are conducted by Romax and AGMA standard, which shows that the scheme with smaller size can offer larger transmission power and meet the requirements of the coaxial output.
