Abstract
An assembly for absorbing torques at the rotor hub of a wind turbine whose rotation axis extends toward the wind, and for diverting axial and radial forces and tilting moments into a load-bearing structure by means of a main bearing, and for extracting rotational energy from the rotor hub by means of a gear whose planet gears mesh with a sun gear and a ring gear, and comprising a generator connectable to an output side of the planetary gear, and operates to convert the rotational energy into electrical energy, wherein the planetary gear is integrated with a main bearing of a wind power plant, and the ring gear of the planetary gear is driven by the rotor hub, while the planet gear carrier is fixed to the chassis of a gondola of the power plant, and the sun gear of the planetary gear mechanism is drivingly connected to the generator, and the generator does nor protrude radially beyond the rotor bearing or main bearing.
