A mainframe mounts the drivetrain of a wind turbine, and to an arrangement comprising such a mainframe, and to a wind turbine having a corresponding arrangement. For the purpose of mounting the drivetrain of a wind turbine, the mainframe is realized with two bearing points that are spaced apart from each other, a partial flange, having a fastening region shaped as a circular ring segment, being provided at at least one bearing point. The arrangement comprises, besides the mainframe, at least one ring element configured to radially encompass the drivetrain. At least one ring element is fastened to the fastening region, shaped as a circular ring segment, of a bearing point of the mainframe. In the case of the wind turbine, the drivetrain is mounted by means of the described arrangement.

Mainframe for wind turbines

A wind turbine has a drive train that comprises a rotor shaft and a planetary gear train having a first gear stage, the rotor shaft being connected to the planet carrier of the first gear stage in a fixed and backlash-free manner. The rotor shaft is supported, on the side that faces away from the first gear stage, by a toroidal roller bearing, on a first carrying structure. The planet carrier that is connected to the rotor shaft in a fixed and backlash-free manner is supported by a moment bearing, as a fixed bearing. The outer ring of the moment bearing is connected to a housing. The combination of the outer ring of the moment bearing and the housing is connected to a second carrying structure via at least three elastic suspension elements arranged in an annular manner around the rotor axis.

A blade adapter for rotor blades of wind turbines, for increasing the rotor diameter, has a first end for attaching to the rotor hub, and a second end, spaced apart in the axial direction, for connecting to the blade root of a rotor blade. In addition, the blade adapter, at its first and second end, has a pitch circle for connecting to the rotor hub or to the rotor blade, wherein the wall of the blade adapter extending in the axial direction is open outwardly, in the form of a truncated cone, from the first end toward the second end, in at least one portion.

A nacelle component for a nacelle of a wind turbine, comprising a mainframe module and a power electronics module. The mainframe module and the power electronics module in each case have a length greater than a width. In the assembled state of the nacelle component, the mainframe module is oriented with its longitudinal axis parallel to a vertical plane which extends through the axis of a rotor shaft. The longitudinal axis of the power electronics module intersects the vertical plane which extends through the axis of the rotor shaft. A method for mounting such a nacelle component is also disclosed.

The present invention provides an apparatus for the controlled rotation of a nacelle of a wind turbine, which includes a control device and n of yaw brakes. In standstill operation, the n yaw brakes are actuated to impart a standstill holding moment Mfor holding the nacelle, and the n yaw brakes impart a substantially equal first holding moment.
