<p>The present invention relates to a blade angle adjusting device for a wind power generator, which includes a rotational displacement transmitter (200) mutually connecting an auxiliary blade connection shaft (110) with a blade connection shaft (120) so that the rotation of a blade is controlled proportionally according to the angular displacement of a rotating auxiliary blade. The rotational displacement transmitter (200) comprises: a sun gear (210) which rotates around the auxiliary blade connection shaft (110) and is fitted with external gear teeth, a ring gear (220) which rotates around the blade connection shaft (120) and is fitted with internal gear teeth and installed surrounding the sun gear (210) with a gap therebetween, and a rotating gear (230) which rotates in place with the interior and exterior sides meshed with the sun gear (210) and the ring gear (220) and thus turns the ring gear (220) in the same direction as the sun gear (210) in proportion to the angular displacement of the sun gear (210). A rotational displacement transmission structure is implemented as above in which the rotational displacement of the auxiliary blade is reliably transmitted to the blade. Therefore, conventional blade interference caused by transmitting the rotational displacement and torque of an auxiliary blade to a blade using a single internal gear and a single external gear can be prevented.</p> |
