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 an annulus gear. The gearbox is used to transfer and speed-up the rotation of a rotor of the wind turbine, as applied to at least one generator of the wind turbine. 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. The self tracking bearing includes bearing elements for locally transferring loads in both radial directions between one or more bearing rings.
