Abstract

The invention relates to an epicyclic gear stage for a wind turbine gearbox comprising a sun gear, at least two planet gears, engaged with said sun gear, an annulus gear, and a planet carrier. Torque from the wind turbine rotor is transferred via a torque transfer part connected to said planet carrier and said torque transfer part is flexible connected to said planet carrier at one or more joints.
