Abstract

A wind-power plant with a rotor. The rotor's hub is accommodated in a roller bearing. The roller bearing is mounted on a support and connected to a planetary gear. The planetary gear comprises two stages, specifically an input stage and an output stage. The planetary gear's output shaft is coupled by way of a clutch to a generator. The roller bearing (3) has an inner ring (7) that is attached to and can be detached from both the hub (1) and the rotating part of the planetary gear. The generator (11) has a housing that is combined with and can be removed from the planetary gear to constitute a drive-train module. The module rests on the rotor support (4) and can be dynamically separated from the overall plant.
