PITCH DRIVE APPARATUS OF WIND GENERATOR AND WIND GENERATOR

摘要

The invention provides a pitch drive apparatus of a wind generator and the wind generator capable of, with a simple structure, preventing reliability of the pitch drive apparatus from being deteriorated. The wind generator includes a wind turbine rotor blade having a blade root mounted so as to be turnable around an axis center O with respect to a rotor head, and a pitch drive apparatus for turning and driving the wind turbine rotor blade around the axis center O to change a pitch angle thereof. The pitch drive apparatus has an electric cylinder functioning as a linear actuator.
