The invention discloses an electrically-driven variable-pitch propeller device with high torque output. The electrically-driven variable-pitch propeller device comprises blades, a variable-pitch assembly, a flange cover plate, a transmission shaft and a propeller hub, the variable pitch assembly comprises a motor assembly, a planetary gear pair, n worm and gear pairs and a paddle root metal assembly, the planetary gear pair comprises a sun gear and n planet gears, and the sun gear and the planet gears are fixedly connected; and the planet gears correspond to the worm and gear pairs one by one. The blades are disassembled from the outside of the propeller hub side cavity and matched with the pitch changing assembly, the sun gear of the planetary gear set is driven by the motor to rotate, the planetary gear and the worm are driven to rotate together, and the rotation of the blades is achieved in a worm and gear transmission mode to change the pitch. The device is convenient to disassemble and assemble, tail end self-locking can be achieved, the control precision is high, and large variable pitch torque can be provided.

    本发明公开一种大力矩输出的电驱变距螺旋桨装置,包括桨叶、变距组件、法兰盖板、传动轴、桨毂;变距组件包括电机组件、行星齿轮副、n个蜗轮蜗杆副和桨根金属组件,行星齿轮副包括一个太阳轮和n个行星轮,所述太阳轮和行星轮固连;行星轮和蜗轮蜗杆副一一对应。桨叶从桨毂侧腔外拆装与变距组件配合,通过电机驱动行星齿轮组的太阳轮旋转,带动行星轮和蜗杆一同旋转,并采用蜗轮蜗杆的传动方式实现桨叶的旋转进行变距。装置拆装方便,能实现末端自锁,控制精度高,能提供大变桨距力矩。
