WIND POWER GENERATOR AND FRICTION NOISE REDUCTION METHOD THEREOF

摘要

The present invention relates to a wind power generator and a frictional noise reduction method thereof. The wind power generator comprises: a tower installed on the ground in a vertical direction; a nacelle which is mounted on the top of the tower to be rotated and has an accelerator, a generator, and controllers inside; and a rotor mounted at the front end of the rotary shaft of the generator. A sound-absorbing material is installed on the inner side of the tower to absorb frictional noise from the yawing motion of the nacelle and to reduce noise transmitted to the outside of the tower. Therefore, the wind power generator prevents frictional noise from the yawing motion of the nacelle from being transmitted from the top of the tower to the bottom and from being transmitted to the outside of the tower by absorbing and reducing the frictional noise.
