Abstract: The invention relates to a single-point mooring wind turbine having a rotor arranged on a tower, characterized by a design counteracting sway of the wind turbine caused by the rotor torque.

Abstract: A wind turbine includes a floating foundation having a plurality of buoyancy bodies, the buoyancy bodies being formed from a plurality of buoyancy body elements designed as hollow bodies, which are arranged adjacent to one another in a first plane concentrically around each central element extending from the floating foundation and are connected to said central element. Each buoyancy body element has a surface supported on the central element, a convex surface arranged opposite the central element, and two lateral surfaces each supported on a lateral surface of an adjacent buoyancy body element.

Abstract: The invention relates to a single-point mooring wind turbine having a rotor arranged on a tower, characterized by a design counteracting sway of the wind turbine caused by the rotor torque.

Abstract: A method for moving a double-bladed rotor of a wind power plant into a parking position characterized by the orientation of the rotor blades in a horizontal plane and braking the rotor.

Abstract: The invention relates to a wind turbine comprising a tower, a nacelle that is located on the tower and is provided with a machine support, a rotor shaft bearing and a generator, and comprising a rotor with a rotor shaft, a rotor hub and at least one rotor with at least one rotor blade that is fixed to the rotor hub. According to the invention, the wind turbine has a locking device established by a locking bolt that can be driven into a locking bolt recess in order to positively lock the rotor. The invention is characterized in that the locking bolt is located on the rotor hub and the locking recess is located on the nacelle.

Abstract: A hydraulic supply unit for lubricating and/or cooling mechanical and electrical components disposed in the nacelle of a wind power plant, and for supplying hydraulic actuating devices with hydraulic fluid, characterized by a tank that is divided into chambers and has a first chamber for providing oil lubricating the gearbox of the wind power plant, a second chamber for providing hydraulic oil used to operate hydraulic actuating devices of the wind power plant, a first connection for connecting the first chamber to a line for supplying the gearbox with lubricating oil, and a second connection for connecting the second chamber to a line for supplying the hydraulically operated actuating devices with hydraulic oil, and a heat exchanger for dissipating heat from the hydraulic oil, the gearbox oil and a coolant that is fed to the heat exchanger and absorbs lost heat at the electrical components of the wind power plant.

Abstract: Wind turbines with at least one rotor blade, a hub, a gearbox casing accommodating a gearbox, a generator casing accommodating a generator, a head support, a tower and an azimuth bearing supporting the head support so that it can rotate on the tower, characterized in that the rotor bearing, the gearbox casing and the generator casing are arranged between the hub and the head support, designed as load-transmitting components and joined to each other via screw connections.

Abstract: A planetary gear including a stationary ring gear, a rotatable planet carrier having an even number of at least four mirror-symmetrically arranged planet wheels, and a sun gear and comprising two bearings disposed opposite of the sun gear and arranged between the planet wheels is provided. The bearings connect the input or output element of the planetary gear to the planet carrier in the center plane of the planet carrier, with the bearings forming an imaginary axis of symmetry, and at least two planet wheels having a lesser distance to each other than one of the planet wheels does to a further planet wheel.

Abstract: A sealing arrangement includes a housing component, a shaft at least partially accommodated by the housing component, and a plurality of sealing elements, which can be moved along the longitudinal axis of the shaft for sealing the intermediate space between the housing component and the shaft. The shaft includes a section that extends in the longitudinal direction of the shaft and has a shaft diameter that is tapered in steps. The sealing elements can be moved from a first position, in which a first sealing element lies against a first step, to further positions, in which additionally at least one further sealing element lies against one further step per sealing element.
