  • Drive train for a wind turbine
    Patent number: 8197215
    Abstract: A drive train for a wind turbine, comprising a main bearing arrangement in the form of a single locating bearing arranged to support a main shaft. An outer raceway of the main bearing is coupled to a support structure, such as a base frame of a nacelle, via flange parts arranged on the outer raceway and the support structure, respectively. The flange parts define interfacing surfaces extending in a plane which is arranged non-parallel, preferably substantially perpendicular, to the rotational axis of the main shaft. Thereby a service friendly design is obtained, in which the main bearing and/or the main shaft can be repaired and/or replaced without having to remove the rotor from the nacelle.
