The embodiment of the invention provides a variable-speed transmission system and an unmanned aerial vehicle. The input end of a first gear train of the transmission system is used for being arrangedon an input shaft in a sleeving mode, and an overrunning clutch is arranged in the output end of the first gear train in a sleeving mode; the overrunning clutch is used for sleeving the input end of amechanism; the output end of a second gear train is used for sleeving the input end of the mechanism, and the input end of the second gear train is connected with the output end of the clutch; and the input end of the clutch is sleeved in the output end of a third gear train, and the input end of the third gear train is used for sleeving the input shaft. Under the condition that the input shaft is at a low rotating speed, the overrunning clutch is in a combined state, and the clutch is in a separated state; and under the condition that the input shaft is at a high rotating speed, the overrunning clutch is in an overrunning state, and the clutch is in a combined state. Therefore, by applying the scheme provided by the embodiment of the invention, the helicopter can achieve the optimal aerodynamic performance in the two aerodynamic environments.

    本发明实施例提供了一种变转速传动系统及无人机,该传动系统的第一轮系的输入端用于套设在输入轴上,第一轮系的输出端内套设有超越离合器;超越离合器用于套设在机构的输入端上;第二轮系的输出端用于套设在机构的输入端上,第二轮系的输入端连接离合器的输出端;离合器的输入端套设于第三轮系的输出端内,第三轮系的输入端用于套设在输入轴上;在输入轴呈低转速的情况下,超越离合器处于结合状态,离合器处于分离状态;在输入轴呈高转速的情况下,超越离合器处于超越状态,离合器处于结合状态。可见,应用本实施例提供的方案能够使得直升机在上述两种气动环境下均达到最优的气动性能。
