The invention relates to a two-degree-of-freedom parallel rotor wing driving device which comprises a machine base, a movable platform and a plurality of branches, a first motor, a lead screw motor and a ball screw are fixed to the machine base, an engine is arranged on the movable platform, an output shaft of the engine is connected with a rotor wing shaft, and the rotor wing shaft penetrates through a ball sleeve arranged in the machine base to be connected with a rotor wing. An output shaft of the first motor is connected with the swing supporting plate, the two ends of the two ball rod branches are connected with the swing supporting plate and a movable platform ball pair respectively, an output shaft of the lead screw motor is connected with the ball screw, a sliding block is arranged on the ball screw, the first end of the straight rod branch is connected with the sliding block ball pair, and the second end of the straight rod branch is connected with a movable platform rotating pair. The flexible branches are evenly distributed between the machine base and the movable platform, and the two ends of each flexible branch are in spherical pair connection with the machine base and the movable platform. The structure is simple and compact, safety and reliability are achieved, meanwhile, loads generated by the rotors can be shared through the flexible branches, and the rotor shafts are assisted to return to the optimal flight attitude.

    本发明涉及一种两自由度并联旋翼驱动装置,其包括机座、动平台以及多个分支,机座上固定有第一电机、丝杆电机以及滚珠丝杠,动平台上设有发动机,且发动机的输出轴与旋翼轴连接,旋翼轴穿过设于机座中的球套与旋翼连接,第一电机的输出轴与摆动支板连接,且两个球杆分支的两端分别与摆动支板以及动平台球副联接,丝杆电机的输出轴与滚珠丝杠连接,且滚珠丝杠上设有滑块,直杆分支的第一端与滑块球副联接,且其第二端与动平台转动副联接,柔性分支均布设于机座与动平台之间,且每个柔性分支的两端均与机座以及动平台球副联接。本发明结构简单、紧凑、安全可靠,同时采用柔性分支可以分担旋翼产生的载荷,助力旋翼轴回复至最佳飞行姿态。
