Patent ID: 8456034

Claim:
A wind power generator, comprising: a rotating shaft rotatably supported by upper and lower bearing units installed on a support frame; a disc mounted on the rotating shaft; a plurality of first wind collectors provided on upper and lower surfaces of the disc and having holes formed through the disc, thus collecting wind blowing on the upper and lower surfaces of the disc and rotating the rotating shaft; and a plurality of second wind collectors installed on inclined frames mounted both to the rotating shaft and to the upper and lower surfaces of the disc, thus collecting wind blowing on the disc and rotating the rotating shaft, wherein, the upper bearing unit comprises: an adjusting bolt having a first ball at a lower end thereof; a first bearing without an inner race, the first bearing supporting a lower surface of the first ball while realizing point contact rolling of the first ball; and an adjusting nut tightened to an upper end of the adjusting bolt at a location on an upper surface of the support frame, wherein an upper end of the rotating shaft is coupled to a first spline mounted to a lower end of a first bearing seat; the lower bearing unit comprises: a second bearing without an inner race; a second ball supported by the second bearing while realizing point contact rolling relative to the second bearing; and a second spline mounted to an upper end of the second ball, wherein a lower end the rotating shaft is coupled to the second spline; and a rotation transmitting element is provided in a lower portion of the rotating shaft and transmitting a rotating force of the rotating shaft to a power generating device.
