WIND POWER GENERATOR

摘要

A wind power generator is disclosed. The wind power generator according to an embodiment of the present invention comprises a rotor hub and a rotor blade coupled to the rotor hub. The wind power generator comprises: a pitch bearing having an outer ring coupled to one side of the rotor hub, and an inner ring coupled to the inner circumference of the outer ring to be able to rotate and coupled to a root part of the rotor blade; and a reinforcement member for preventing the deformation of the inner ring in a radius direction of the inner ring. A protrusion protruding toward the rotor hub is formed on one side of the reinforcement member facing the rotor hub. A support part is arranged on the inner circumference of the inner ring. An insertion groove in which the protrusion of the reinforcement member is inserted is formed in the inner circumference and the support part of the inner ring.
