A WIND TURBINE COMPRISING TWO OR MORE ROTORS
First Claim
1. A wind turbine comprising:
- a tower structure comprising a main tower part being anchored, at a lower part, to a foundation structure, the main tower part extending along a substantially vertical direction, the tower structure further comprising at least two arms, each arm extending away from the main tower part along a direction having a horizontal component, andtwo or more rotors mounted on the tower structure in such a manner that each arm of the tower structure carries at least one rotor, each rotor comprising a hub carrying a set of wind turbine blades, the hub being mounted rotatably on the tower structure;
a rotating shaft arranged to be connected to a generator in order to transfer rotational movements to the generator; and
a gear arrangement arranged to transfer rotational movements of the hub to rotational movements of the rotating shaft,wherein the gear arrangement of at least one of the rotors comprises a number of pulleys and a number of belts interconnecting the pulleys in order to transfer rotational movements between the pulleys, thereby transferring rotational movements from the hub to the rotating shaft.

Abstract
A multirotor wind turbine (1) comprising a tower structure with a main tower part (2) and at least two arms (3), each arm (3) extending away from the main tower part (2) along a direction having a horizontal component. Two or more rotors (4) are mounted on the tower structure in such a manner that each arm (3) of the tower structure carries at least one rotor (4). A gear arrangement (9) of at least one of the rotors (4) comprises a number of pulleys (10, 11, 13) and a number of belts (16, 17) interconnecting the pulleys (10, 11, 13) in order to transfer rotational movements between the pulleys (10, 11, 13), thereby transferring rotational movements from the hub (5) to a rotating shaft (14) connected to a generator (15).
