Abstract
A wind turbine with a drive train placed partly or entirely in a nacelle of the wind turbine is provided. The drive train includes an epicyclical gearbox including at least one gear stage having a plurality of planet gears meshing with a sun gear and/or an annulus gear. The gearbox partly or completely speed-up the rotation speed of a rotor of the wind turbine to at least one generator of the wind turbine. The wind turbine is characterized in that the drive train further includes at least one locally radial self tracking bearing for enabling the rotation of the rotor in relation to a nacelle structure of the nacelle.

A wind turbine with a drive train placed partly or entirely in a nacelle of said wind turbine, said drive train comprising an epicyclical gearbox including at least one gear stage comprising a plurality of planet gears meshing with at least one of a sun gear and an annulus gear, said gearbox partly or completely speed-up the rotation speed of a rotor of said wind turbine to at least one generator of said wind turbine characterized in that
- said drive train further comprises at least one locally radial self tracking bearing for enabling rotation of said rotor in relation to a nacelle structure of said nacelle wherein said locally radial self tracking bearing comprises means for locally transferring loads in both radial directions between one or more bearing rings directly or indirectly connected to said rotor and one or more bearing rings directly or indirectly connected to said nacelle structure.
