Abstract

A direct driven wind turbine and a main bearing used in such a wind turbine is provided. A rotor of the wind turbine is directly connected with a rotating drive train of the wind turbine, the rotating drive train is directly connected with a rotor of an electrical generator of the wind turbine. The rotating drive train is connected with a stationary part of the wind turbine via at least one bearing, which allows the rotation of the drive train in relation to the stationary part. The at least one bearing is a plain bearing and the bearing is a tapered bearing, which comprises at least one conical shaped sliding surface.
