PURPOSE: A floating blade apparatus for a wind power generator is provided to reduce the dynamic load and ensure smooth operation because the blades float when rotated by the wind force. CONSTITUTION: A floating blade apparatus for a wind power generator comprises a main rotary shaft(110), a sub rotary shaft, an upper bearing(140), a taper needle bearing(200), a shaft guide(130), a plurality of supporting frames(300), and arc-shaped blades(B). The sub rotary shaft is arranged separate from the main rotary shaft on the same axis. The upper bearing supports the top of the main rotary shaft to move up and down. The taper needle bearing is arranged between the main rotary shaft and the sub rotary shaft and supports the main rotary shaft to float. The shaft guide houses the sub rotary shaft and fixes the taper needle bearing. The supporting frames are fixed to the shaft guide and the upper bearing. The blades are arranged inside the supporting frames and vertically fixed to the main rotary shaft with L-shaped floating guide members(400). |
