Abstract:
A rotating unit for rotating a first component of a wind turbine rotatably mounted on a second component, which includes a gearwheel element arranged on the first component, a drive arranged on the second component by a drive holder including a drive housing and a drive pinion for actuating the gearwheel element, a connecting element arranged on the drive housing and configured to form a releasable connection between the drive housing and the drive holder, and fastening means, which interact with the connecting element and can be actuated between a clamping position and a disengagement position. The fastening means connect the drive housing, in the clamping position, in a force-fitting manner to the drive holder. In the disengagement position, the drive housing is displaceable on the drive holder in an adjustment direction such that it is possible to adjust a tooth-flank clearance between the drive pinion and the gearwheel element.
Abstract:
The invention relates to a test bench (1) for testing a drive train of a wind turbine, comprising a drive device (40) for introducing test power into the drive train, which can be detachably connected to a drive train to be tested. The invention further relates to a method for testing a drive train of a wind turbine by way of a test bench (1), and to a drive train of a wind turbine. The test bench (1) according to the invention is characterized in that the drive device (40) for testing a drive train is or will be fitted and mounted on or to the drive train so as to be removable, wherein most of the weight of the drive device (40) is borne by the drive train when the drive device (40) is fitted or mounted.

Abstract:
A method for operating a wind turbine having a nacelle disposed in a rotatable manner on a tower and a rotor having three rotor blades, which can be brought into a standstill position after a stoppage command, and in which at least two of the three rotor blades can be pitched about a rotor-blade longitudinal axis, which includes rotating the nacelle into an azimuth position transverse to a wind direction to attain the standstill position, bringing/holding a rotor blade into a range of an operating position that corresponds substantially to a blade pitch angle in a partial-load range below a full-load range of the wind turbine and bringing/holding each of the other two rotor blades into a range of a feathered position, wherein the rotor, after attainment of the standstill position, is stabilized by incident wind flowing transversely in relation to a direction of a rotor axis.
Abstract:
The invention relates to a turn drive for a wind turbine. The turn drive comprises a shaft, a hydraulic motor for driving the shaft, and a drive line for supplying a pressurized hydraulic fluid to the hydraulic motor. According to the invention, the drive line is provided with a settable pressure-limiting valve. The invention additionally relates to an associated method for rotating the rotor shaft of the wind turbine. By means of the method according to the invention and the turn drive, the rotor blades can be mounted individually on the hub of the rotor, without the gearbox of the wind turbine becoming overloaded.
Abstract:
A method for handling a wind powerplant's rotor hub or to handle a wind powerplant's rotor using a hoist, in particular for erecting a wind powerplant or for assembling or disassembling a rotor to and from such a powerplant, in particular a hub or a rotor being configured by means of one assembly side to the wind powerplant's tower, the hub or rotor being raised or held by the hoist. In the raised state, the hub is tilted by a tilting mechanism acting on it out of the initial, raised position by a predetermined angle of tilting, or the rotor is tilted by a tilting mechanism acting on the rotor blade roots of the rotor through a predetermined angle of tilting. A mechanism to handle a wind powerplant's rotor hub of a wind powerplant's rotor, in particular for assembling or dismantling a rotor to or from its wind powerplant.
