<P>PROBLEM TO BE SOLVED: To provide a device capable of reliably operating a brake and a clutch as measures against the strong wind at low cost in a small-sized wind power generator. <P>SOLUTION: In the centrifugal brake and the clutch, a main rotation shaft A transmitting rotation and a shaft B driven and rotated by receiving the rotational force are provided, a non-slip round washer having is fixed on the end thereof, and the main rotational force is easily transmitted from the shaft A to the shaft B. By operation of a spring and a centrifugal pendulum attached on the rotation shaft A side, when a number of revolutions is raised to a predetermined number, brake is operated, and the main rotation shaft A and the driven rotation shaft B are separated in the number of revolutions higher than it, and the transmission of the shafts A and B is disconnected by variation of the number of revolutions. Operation is performed without the usage of electric power so as to prevent a fault of a motor or a power generator connected to the driven shaft B side. Therefore, the small-sized wind power generator exhibiting high safety can be manufactured at the low cost. <P>COPYRIGHT: (C)2007,JPO&INPIT |
