The invention discloses a variable pitch impeller with small blade rotation resistance and a wind driven generator. According to the adopted technical scheme, the impeller comprises a main shaft, a wheel carrier fixed at one end of the main shaft, and a group of blades distributed on the wheel carrier in a surrounding mode; and the impeller is characterized in that the blades are rotatably connected with the wheel carrier, a variable pitch mechanism is arranged between the main shaft and the wheel carrier, when the blades roll to the position above the center line of the wheel carrier, the blades are perpendicular to the wheel carrier through the variable pitch mechanism, and when the blades roll to the position below the center line of the wheel carrier, the blades are parallel to the wheel carrier through the variable pitch mechanism.

    本发明公开一种桨叶回转阻力小的变桨叶轮以及风力发电机。采用的技术方案包括:主轴、固定于所述主轴一端的轮架、周围分布于所述轮架上的一组桨叶,其特征在于:所述桨叶与所述轮架之间为可转动连接,所述主轴与轮架之间设有变桨机构;当所述桨叶滚动至所述轮架的中心线上方时,通过所述变桨机构,使所述桨叶与所述轮架垂直;当所述桨叶滚动至所述轮架的中心线下方时,通过所述变桨机构,使所述桨叶与所述轮架平行。
