Abstract:
An apparatus for generating power using wind energy, comprising blades for receiving the wind energy, further comprising:a plurality of connecting shafts arranged around a boss and rotatably supported by the boss, each of the connecting shafts extending radially and supporting an associated one of the blades; pinions each fitted around an associated one of the connecting shafts to rotate along with the associated connecting shaft; rack housings each fixedly mounted to the boss near an associated one of the pinions; rack gears each slidably received in an associated one of the rack housings and engaged with an associated one of the pinions; springs each fitted around a portion of an associated one of the rack gears extending beyond the rack housing receiving the associated rack gear and adapted to urge the associated rack gear toward an end of the associated rack gear protruded from the associated rack housing; and spring force adjusting knobs each threadedly coupled to the protruded end of an associated one of the rack gears and adapted to adjust a spring force of an associated one of the springs, whereby each of the blades is angularly shifted about an axis orthogonal to a rotating shaft for the blades in response to a variation in a pressure of wind applied to the blades.
