摘　　要：研究了单输入双输出的定轴轮系与差动轮系组合的俄卡-32直升机传动系统典型构型,对共轴式反转双旋翼直升机的研制具有重要的意义。为避免传动系统差动轮系出现功率流循环而降低传动效率,对该传动构型的功率流进行了研究,得到了功率流循环的影响因素和传动功率分配比,为直升机传动系统自主设计提供了支撑依据。The typical structure of the Eckasha-32 helicopter transmission with a combination of the fixed axis gear train and the differential gear train with the character of the single input and double output is stuchied,it’s significant for the development of the coaxial counter- rotating twin- rotor helicopter. In order to avoid lowering the transmission efficiency caused by the cycle power flow,the cycle power flow of the transmission is studied,the factors of the cycle power flow and the transimission power distribution table are obatained. The results can provide the basis for the design of the transmission system of the helicopter.
