摘要： A wind turbine includes at least one wind turbine blade assembly. The blade assembly includes a blade and a pitch bearing arranged between the blade and a hub of the wind turbine, the blade assembly further including two or more hydraulic pitch cylinders for pitching the blade in relation to the hub. The two or more hydraulic pitch cylinders are arranged to expand in the same angular direction around the rotational axis of the pitch bearing. A method for pitching a blade of a wind turbine includes connecting a first end of the hydraulic pitch cylinders directly or indirectly to the hub; connecting a second end of the hydraulic pitch cylinders directly or indirectly to the blade; and expanding or contracting the hydraulic pitch cylinders in the same angular direction in relation to the rotational axis of the pitch bearing.

摘要： The invention provides a bearing for attaching a wind turbine blade to a wind turbine hub, the bearing comprising a stationary ring, a movable ring which can rotate relative to the stationary ring, a grease lubrication structure, and a canister for collecting grease. The grease lubrication structure forms an outlet for releasing grease from a space between the stationary ring and the movable ring and the canister comprises an inner space with at least one inlet in releasable fluid communication with the outlet. The outlet and the inlet comprise cooperating coupling elements adapted for releasable snap-connection of the outlet to the inlet. Due to the snap-connection, the canister is easily removed and replaced in connection with maintenance of the wind turbine even though the space in the hub is typically very limited.

摘要： A wind turbine having a tower and a rotor hub that is supported by the tower. At least one blade extends from the rotor hub, and a nacelle is located proximate the rotor hub. The wind turbine also has a transport conduit that selectively provides communication between an interior of the nacelle and an interior of the rotor hub. The transport conduit may have a collapsed condition in which the transport conduit is located completely within the nacelle, and an extended condition in which the transport conduit partially extends into the interior of the rotor hub. In a specific embodiment, the transport conduit is a telescoping structure. A method for using the transport conduit includes accessing the interior of the nacelle to position an object therein and transporting the object to the interior of the rotor hub using the transport conduit.
