The invention discloses a power transmission device of an oil-driven ducted aircraft. The power transmission device comprises an engine rotary shaft connected with an engine and a clutch; the clutch comprises a clutch inner wall, clutch flying blocks and tension springs; the clutch fly blocks are connected with the engine rotary shaft through revolute pairs, the number of the clutch fly blocks is even, and every two clutch fly blocks form a group; the center of gravity of the clutch fly blocks is eccentric relative to the connection position of the revolute pairs, and the tension spring is connected between every two opposite clutch fly blocks; when the clutch fly blocks are centrifuged towards the periphery, friction can be generated between the clutch fly blocks and the clutch fly blocks; and the clutch inner wall and a clutch output shaft connected with a propeller move synchronously. The centrifugal clutch is used for driving the propeller to rotate, and it is ensured that an engine can be started and stopped in a no-load mode; and compared with a traditional belt type transmission or direct connection type ducted aircraft, the clutch device prevents a propeller rotary shaft and related parts from instantly bearing large loads, and then serious loss of the related parts and unnecessary oil consumption are avoided.
本发明公开了一种油动涵道飞行器动力传动装置,包括与发动机连接的发动机转轴和离合器;离合器包括离合器内壁、离合器飞块和拉簧;离合器飞块与发动机转轴通过转动副连接,且数量为偶数个,两两一组;离合器飞块的重心相对于转动副连接位置是偏心,两两相对的离合器飞块之间连接有拉簧;所述离合器飞块向四周离心时能与离合器飞块能够发生摩擦;离合器内壁与连接螺旋桨的离合器输出轴同步运动。本发明利用该离心式离合器驱动螺旋桨转动,确保发动机可以空载启动和停止;与传统带式传动或直接连接式的涵道飞行器相比,本离合装置避免了螺旋桨转轴及相关零部件瞬间承受较大载荷,进而避免了相关零件的严重损耗以及不必要的油耗。
