The invention relates to a wind turbine (1) comprising a nacelle, a hub (4) carrying one or more rotor blades (13), the hub (4) being rotatably mounted on the nacelle, at least one rotating shaft (14) arranged to be connected to a generator (12) in order to transfer rotational movement to the generator (12), and a gear arrangement (7) arranged to transfer rotational movements of the hub (4) to rotational movements of the at least one rotating shaft (14). The gear arrangement (7) comprising at least one first belt (15) interconnecting a primary pulley (8) to each of the planetary shafts (10), at least one second belt (16a, 16b, 16c) interconnecting a first planetary pulley (9) to a first centre pulley (11, 11a, 11b, 11c), and at least one third belt (16a, 16b, 16c) interconnecting a second planetary pulley (9) to a second centre pulley (11, 11a, 11b, 11c). |
