Title:
ROTATION TRANSMISSION DEVICE AND WIND POWER GENERATION APPARATUS PROVIDED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2015/022934
Kind Code:
A1
Abstract:
A rotation transmission device is provided with a one-way clutch which is provided between an output shaft of a speed-increasing gear and an input shaft of a power generator, integrally and rotatably connects the output shaft and the input shaft while the rotation speed of the output shaft is higher than the rotation speed of the input shaft, and cuts off the connection between the output shaft and the input shaft while the rotation speed of the output shaft is lower than the rotation speed of the input shaft. The rotation transmission device is further provided with a measurement unit which measures the state of the one-way clutch, the state changing according to the magnitude of a load applied to the one-way clutch, and an acquisition unit which acquires the load applied to the one-way clutch on the basis of the result of the measurement by the measurement unit.
