Abstract

A wind energy plant with a rotor, which is connected to a gearbox and/or a generator via a rotor shaft, wherein the rotor shaft is bearing mounted on a carrier unit via two taper roller bearings in an O arrangement, characterized in that each taper roller bearing has an inner and an outer race, wherein the inner races and the outer races are secured in their distance to each other in the axial direction with respect to the rotational axis of the rotor shaft via an adjustment device.
