WIND POWER GENERATOR

摘要

Disclosed is a wind power generator. The wind power generator according to an embodiment of the present invention includes a main shaft that is connected to a rotor; a main frame that rotatably supports the main shaft; a nacelle cover that surrounds the main frame; a rotor lock disk that is attached to the outer circumferential surface of the main shaft at the front side of the main frame; and a sealing structure that seals a separated space which is formed between the nacelle cover and the outer circumferential surface of the rotor lock disk. The sealing structure has a base member that is fixed to the main frame at the rear side of the rotor lock disk; a first sealing member that seals a gap between the base member and the outer circumferential surface of the rotor lock disk; and a second sealing member that seals a gap between the nacelle cover and the base member.
