The invention relates to a wind turbine for generating electric power by an air stream () onto a rotor () rotatable about a rotor axis (), said rotor comprising a plurality of rotor blades () and being coupled via a rotor shaft () to a generator (), wherein a primary transmission () is present between the rotor shaft () and generator input shaft () for multiplication of the rotational speed, wherein the pressure-feed or force-feed lubricating system of said main transmission comprising a lubricating pump () enables the supply to components () subject to wear, wherein the wind turbine () has an emergency pump () for lubricant supply, which during normal operation of the wind turbine is not operational and during spinning operation and/or a power failure can be connected and which is operated by the rotating rotor ().

Wind turbine for generating electric power

An adjusting device for adjusting the rotation angle position of the rotor of a wind energy system should be improved by the invention, whereby a complicated processing of the brake disc previously used for engagement of the drive is no longer necessary, and whereby said brake disc can be flexibly arranged in an area with sufficient construction space. For this purpose, the adjusting device has at least one force transducer wheel and/or a force transducing disc which is mounted or can be mounted on a shaft () of the drive train which is switched downstream from the rotor, which is structured for engagement of a force transmitting means, and is designed as an independent component. The device also has a drive means for producing a drive force, and at least one force transmission means for transmitting the drive force to the force transducer wheel and/or the force transducing disc.

What is disclosed is a wind turbine comprising a tower with a closable climbing opening and electrical components disposed inside the tower. In order to provide said wind turbine with the ability to provide a cooling system for cooling the electrical components, in particular the electrical components disposed in the area near the base of the tower, said cooling system able to be cost-effectively installed, it is proposed that the door opening of the wind turbine be located in a continuous tower port which is larger than the door opening, with air intake and exhaust openings passing through said tower port for passage of cooling air.

Wind power plant with improved cooling air conduction

The present invention provides a bearing housing () for accommodating a rotor shaft () of a wind turbine. The bearing housing includes a flange () for connecting the bearing housing to a main frame () of the wind turbine. The flange having a connecting surface () to be attached to the main frame. Thereby, at least parts of the connecting surface, when seen from the top of the bearing housing, would be located below the rotor shaft.

Bearing housing

To facilitate transport and assembly during the erecting of wind power plants, a two-part base frame is proposed for the azimuthal adjustment of the gondola on the tower of the wind power plant, the lower part of whichhas the azimuthal drive deviceand the upper partof which has the drive train. Both parts are pre-assembled at the factory, set onto the tower, and screwed tight onto each other at their connection point

The invention involves a wind power plant for converting wind power into electric energy and a process for replacing machine parts of the housing of a wind power plant of this type using on-board mechanisms. According to the invention, the wind power plant has a tower, a housing that is mounted onto the tower and functions to receive machine parts that include at least one gear and one generator, whereby the housing also has a longitudinal axis oriented essentially crosswise to the tower axis, and, on the underside of a housing part that is set off at a distance from the tower in the direction of the longitudinal axis, has an opening that serves the purpose of allowing machine parts to be moved through it, and the wind power plant also has an on-board crane arranged in the housing in order to convey objects in the direction of the tower axis. Furthermore, the wind power plant has a container functioning to receive structural parts, whereby the container can be moved underneath the opening in the direction of the longitudinal axis from an operating position, in which an area of the opening near the tower is covered by the container, into a mounting position, in which this area of the opening is unblocked.
