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.
