Direct-drive wind turbine

摘要

The invention relates to a direct driven wind turbine with a plain bearing and a service method for this bearing. A rotor of the wind turbine is directly connected with a rotatable drive train of the wind turbine. The rotatable drive train is directly connected with a rotor 5 of an electrical generator 1 of the wind turbine. The rotatable drive train is connected with a stationary part of the wind turbine via at least one bearing 2, which allows the rotation of the drive train in relation to the stationary part. The electrical generator 1 provides a support structure 8 to which the stationary side 7 of the at least one bearing 2 is mounted. The at least one bearing 2 is a plain bearing and the plain bearing 2 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 of the wind turbine and at least one wear-and-tear-part of the plain bearing 2 is exchangeable while the rotatable drive train is fastened to the stationary part.
