  • Power generation device
    Patent number: 9097295
    Abstract: A one-way clutch used in a wind turbine generator connects an input rotor with an output rotor so that the input rotor and the output rotor are rotatable together with each other when a main shaft rotates in a forward direction and rotation speed of the input rotor is higher than rotation speed of the output rotor, and disconnects the input rotor and the output rotor from each other when the rotation speed of the input rotor is lower than the rotation speed of the output rotor. Further, the wind turbine generator includes a second one-way clutch that permits transmission of force caused by the rotation of the main shaft, to the input rotor when the main shaft rotates in the forward direction, and restricts the rotation of the main shaft when the main shaft tries to rotate in a reverse direction.
    Type: Grant
