Abstract

A direct driven wind turbine with a plain bearing and a service method for this bearing is provided. A rotor is directly connected with a rotatable drive train, which is directly connected with a rotor of an electrical generator. The rotatable drive train is connected with a stationary part via at least one bearing, which allows the rotation of the drive train in relation to the stationary part. The generator provides a support structure to which the stationary side of the at least one bearing is mounted. The at least one bearing is a plain bearing and the plain bearing comprises a wear-and-tear-part, which is an object to be exchanged. The rotatable drive train is prepared to be fastened to the stationary part and at least one wear-and-tear-part of the plain bearing is exchangeable while the rotatable drive train is fastened to the stationary part.
