JOINT MEMBER FOR WIND POWER GENERATION APPARATUS, AND WIND POWER GENERATION APPARATUS

摘要

A joint member for a wind power generation apparatus includes: a first rotor integrally rotating with an output shaft of a speed increaser; a second rotor integrally rotating with an input shaft of a generator; and a one-way clutch provided between the first rotor and the second rotor. A torsion promoting portion being readily twisted and elastically deformed is provided at a portion of the first rotor where power is transmitted from the output shaft to the one-way clutch.

1. A joint member for a wind power generation apparatus, which is used for the wind power generation apparatus that generates electric power by rotating an input shaft of a generator by torque from an output shaft of a speed increaser, said joint member comprising:
a first rotor integrally rotating with the output shaft; a second rotor disposed coaxially with the first rotor and integrally rotating with the input shaft; and a one-way clutch which is provided between the first rotor and the second rotor, which connects the first rotor and the second rotor to each other so as to be integrally rotatable when a rotation speed of the output shaft is higher than a rotation speed of the input shaft, and which releases connection between the first rotor and the second rotor when the rotation speed of the output shaft is lower than the rotation speed of the input shaft, wherein a torsion promoting portion being readily twisted and elastically deformed is provided at a portion of the first rotor where power is transmitted from the output shaft to the one-way clutch.
