The invention provides a variable-pitch variable-speed rotor, which is applied to the field of rotors, and is characterized in that the variable-pitch variable-speed rotor comprises a shell, and the shell is rotatably connected with an input shaft and an output shaft; the rotating rod is rotationally connected to the output shaft and driven by the input shaft to rotate, the axis direction of the rotating rod is parallel to the axis direction of the output shaft, a large planetary gear and a small planetary gear are fixed to the rotating rod, a large gear ring and a small gear ring which slide in the axis direction of the rotating rod are assembled in the shell, and the large gear ring and the small gear ring cannot rotate in the radial direction of the shell; the speed change assembly is used for controlling the large gear ring and the small gear ring to be meshed with the large planetary gear and the small planetary gear respectively; the rotating seat rotates along with the output shaft, a tailstock is rotationally connected to the rotating seat, the direction of a rotating shaft of the tailstock is perpendicular to the axis direction of the output shaft, and paddles are assembled on the tailstock; the pitch changing mechanism is used for controlling the tailstock to rotate so as to control the pitch of the paddle; the rotor wing has the technical effects that the propeller pitch and the rotating speed of the propeller blades can be changed, so that the operability of the rotor wing is improved.

    本发明提供一种变距变速旋翼,应用在旋翼领域,其技术方案要点是:包括:壳体,壳体上转动连接有输入轴和输出轴;转动连接于输出轴、受输入轴驱动旋转的旋转杆,旋转杆的轴线方向与输出轴的轴线方向平行,旋转杆上固定有大行星齿和小行星齿,壳体内装配有沿旋转杆的轴线方向滑移的大齿圈和小齿圈,大齿圈和小齿圈无法沿其径向旋转;用于控制大齿圈和小齿圈使其分别与大行星齿和小行星齿啮合的变速组件;跟随输出轴旋转的旋转座,旋转座上转动连接有尾座,尾座的转轴的方向与输出轴的轴线方向垂直,尾座上装配有桨叶;用于控制尾座旋转以此来控制桨叶的桨距的变距机构;具有的技术效果是:能够改变桨叶的桨距和转速,从而提高旋翼的可操作性。
