Abstract

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.
