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.

Wind turbine having drive train

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.
