Document Type and Number:
WIPO Patent Application WO/2013/039292
Kind Code:
A1
Abstract:
The present invention relates to a pitch bearing of a wind power generator, and more specifically to a pitch bearing of a wind power generator which improves reliability of the combination between a blade root for constituting a rotor and a hub by distributing a load applied to a pitch bearing so as to increase the durability of the pitch bearing. The pitch bearing of the wind power generator, according to the present invention, includes: an outer ring (110) fixed to a hub (210) using a first blade bolt (111); an inner ring (120) which is located to be rotatable at both sides of a plurality of first balls (130) at an inner circumference of the outer ring (110) and is fixed to a blade root (220) using a second blade bolt (121); and a rotational supporting member (140) which rotatably supports the inner ring (120) at both sides of a second ball (150) and is fixed to the hub (210) using a third blade bolt (141).
