摘要： A one-way clutch structure includes: a pair of clutch members disposed between an output shaft and a drive shaft so as to oppose each other in an axial direction; and an engagement element interposed between these clutch members. When a rotation speed of the output shaft exceeds a rotation speed of the drive shaft, the engagement element engages with the clutch portion to connect the output shaft and the drive shaft so as to be integrally rotatable. When the rotation speed of the output shaft becomes lower than the rotation speed of the drive shaft, the engagement of the engagement elements is released to cut off connection between the output shaft and the drive shaft.

摘要： A power transmission system for a wind turbine comprises a gearbox and generator. The gearbox includes a gear-box housing and gearbox output member. The generator includes: a generator housing having a drive-end side and non-drive-end side, the drive-end side being coupled to the gearbox housing; a stator supported by the generator housing; a rotor coupled to the gearbox output member so as to be driven thereby; a non-drive-end shield coupled to the non-drive-end side of the generator housing; and at least one auxiliary drive mounted to the non-drive-end shield. The at least one auxiliary drive is configured to rotate the turning gear. A corresponding method of installing a wind farm including such a power transmission system is also provided.

摘要： The wind turbine system (Fig.1, Fig. 2) is a combination of a wind jet turbine (03) and a wind turbine. A wind turbine system (Fig.1, Fig. 2) is assembled around a wind jet turbine (03). The wind turbine hub (02) and the wind turbine hub carrier (01) act as mantle or shroud for the wind jet turbine (03). The wind turbine rotates axial in one direction (13) and the wind jet turbine rotates axial in the opposite direction (14). One part of the generator (e. g. stator (33)) turns with the wind turbine hub (02) and the other part of the generator (e. g. rotor (32)) turns with the wind jet turbine (03).

摘要： There is provided a spar-type floating offshore wind power generation facility that suppresses a reduction in power generation efficiency caused by tilting of a tower, suppresses rotational motion (yaw motion) around a vertical axis, prevents a ship from coming into contact with a mooring cable, and, at the same time, appropriately holds the tilted posture state of the tower. A floating offshore wind power generation facility 1 includes a floating body 2, a mooring cable 3, a tower 4, and a windmill 5 installed at the top of the tower 4, the windmill 5 including a nacelle 6 and a plurality of blades 7. The rotation axis of the windmill 5 has a predetermined upward angle to avoid contact between the blades 7 and the tower 4, and the windmill 5 is of a downwind type in which the blades 7 are attached to the leeward side of the nacelle 6 and installed with the back surfaces of the blades 7 facing windward, and the mooring point of the mooring cable 3 to the floating body 2 is set at a position below the surface of the sea and higher than the center of gravity of the floating body 2.
