A wind power generator is disclosed. According to an embodiment of the present invention, a wind power generator includes: a yaw bearing unit coupled to a tower, and having an inner toothed gear and an outer toothed gear; a yaw drive unit coupled to at least one of the inner toothed gear and outer toothed gear of the yaw bearing unit to provide rotational power; and a main frame configured to allow the yaw drive unit to be seated thereon, and coupled to the yaw bearing unit. Therefore, when the outer toothed gear of the yaw bearing unit is damaged, the yaw bearing unit may be continuously used by the inner toothed gear thereof without replacing the yaw bearing unit. This causes replacement expenses and replacement time to be reduced. |
