The invention discloses a power transmission mechanism of a tilt rotorcraft, and belongs to the field of structural design of power transmission systems. Comprising two power input assemblies, the two power input assemblies are connected with a power dividing assembly, and the power dividing assembly is connected with a power output assembly; a transmission assembly is connected between the two power input assemblies and used for communicating output power of the two power input assemblies. The power output assemblies are connected with the tilting driving assembly, and the tilting driving assembly is used for controlling rotation of the power output assemblies. Due to the fact that the power output assembly is not directly connected with the engine, only the power output assembly needs to rotate during tilting, and the power input assembly and the power dividing assembly can be kept fixed, so that rotational inertia during tilting is reduced, space needed by rotation is reduced, flexible rotation is guaranteed, and streamline design of a fuselage is better facilitated. The transmission assembly is communicated with the two power input assemblies to output power, safety double margins are achieved, and long endurance, large load capacity and high reliability of the aircraft are guaranteed.

    本发明公开了一种倾转旋翼机动力传动机构,属于动力传动系统结构设计领域。包括两个动力输入组件,两个动力输入组件分别连接功率分流组件,功率分流组件连接动力输出组件;两个动力输入组件之间连接传动组件,传动组件用于将两个动力输入组件的输出功率相连通;动力输出组件均连接倾转驱动组件,倾转驱动组件用于控制动力输出组件的旋转。由于动力输出组件没有与发动机直接相连,倾转时只需动力输出组件旋转,动力输入组件和功率分流组件可保持固定,从而减小倾转时的转动惯量,且降低旋转所需空间,保证了转动灵活,更有利于机身的流线型设计;传动组件连通两台动力输入组件输出功率,具有安全双裕度,确保飞机的长航时、大载重量和高可靠性。
