Abstract: The invention relates to a drive arrangement for a wind turbine, and to a wind turbine incorporating a drive arrangement. In one embodiment, a drive arrangement (12) for a wind turbine (10) is disclosed which comprises a rotor shaft (20); a gearbox assembly (22) for transferring torque from the rotor shaft to an electrical power generator (18), the gearbox assembly comprising: an input shaft (40); an output shaft (42); a primary gear stage (44); and a secondary gear stage (46), each gear stage having a plurality of planet gears (52; 58) positioned around the output shaft, an annular gear (84; 86) meshed with the planet gears, and a sun gear (82; 88) meshed with the planet gears and arranged to transfer torque to the output shaft. The drive arrangement also comprises a drive transfer mechanism (24) for transferring torque from the rotor shaft into the gearbox assembly via the input shaft; and a primary load carrying member (56) for releasably mounting the gearbox assembly to a housing (34) of the wind turbine.
