The invention relates to the technical field of aircrafts, and discloses a tiltable rotor mechanism and a rotor aircraft. The tiltable rotor mechanism comprises: a support; the rotating seat is rotatably connected with the support; the rotor wing is rotatably connected with the rotating seat; the sliding block is connected with the support in a sliding mode, and the moving track of the sliding block is perpendicular to the rotating axis of the rotating base. The two ends of the connecting rod are rotationally connected with the sliding block and the rotating seat respectively; the lead screw is rotatably connected with the support, the lead screw is in threaded fit with the sliding block, and the lead screw is parallel to the moving track of the sliding block; the rotation driving mechanism is in transmission connection with the lead screw and used for driving the lead screw to rotate. The tilting rotor mechanism provided by the invention is simpler in structure. The self-locking performance is achieved between the lead screw and the sliding block, so that more stable supporting can be provided for the rotating seat, the rotating seat can stably keep the current angle, the situation that the meshing gear vibrates in the high-frequency vibration process is avoided, and then higher-precision tilting control is given to the rotating seat.

    本发明涉及飞行器技术领域,公开一种可倾转旋翼机构及旋翼飞机。可倾转旋翼机构包括:支座;转动座,与支座可转动地相连接;旋翼,与转动座可转动地相连接;滑块,与支座可滑动地相连接,且滑块的运行轨迹垂直于转动座的转动轴线;连杆,两端分别与滑块和转动座可转动连接;丝杠,与支座可转动地相连接,且丝杠与滑块螺纹配合,丝杠与滑块的运行轨迹平行;转动驱动机构,与丝杠传动连接并用于驱动丝杠转动。本发明提供的可倾转旋翼机构结构更加简单。丝杠与滑块之间具有自锁性能,从而能够为转动座提供更稳定的支撑,使转动座能够稳定地保持当前角度,不会发生啮合齿轮在高频振动中会产生颤振的情况,进而赋予了转动座更高精度的倾转控制。
