WIND DRIVEN GENERATOR

摘要

A wind driven generator provided with a drive train having a reduced axial length and reduced in weight and cost. A wind driven generator for generating electric power by driving a generator which is connected through a drive train to a rotor head which has rotating wind blades mounted thereto and rotates together with the rotating wind blades. A speed-up device (20) of the drive train for transmitting rotational power from the rotor head to the generator has a first stage speed-up section provided with a star type speed-up mechanism integral with a main bearing (50).
