Abstract:
A yawing system for a wind turbine comprising a tower construction and a nacelle. The yawing system comprises a stationary part being connectable to or forming part of a tower construction of a wind turbine, and a rotating part being connectable to a nacelle of a wind turbine. The rotating part is arranged adjacent to the stationary part in such a manner that the rotating part is allowed to rotate relatively to the stationary part via a gear connection between the stationary part and the rotating part. The rotating part comprises a plurality of modules, each comprising a sub-module, the sub-modules being at least substantially identical in size and shape. Each module is configurable to perform various functions, e.g. by positioning one or more function defining elements in the corresponding sub-module. Thereby a configured module belongs to a category of modules reflecting the function of the configured module. At least one of the modules is configured as a drive module adapted to drive a rotational movement of the rotational part relatively to the stationary part, via the gear connection. Due to the similarity in size and shape of the sub-modules, a module belonging to a category may be replaced or reconfigured to belong to a different category of modules without altering the main design of the rotating part. Thereby a highly customizable yawing system is obtained, which can be produced in a cost effective manner.
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).
Abstract:
The invention provides an assembly system (1) for retaining an assembly element (2), the assembly system comprising a structural element (3) with a C-shaped rail (4) forming an elongated slot (5) between opposite edges (6) extending in parallel at a distance, and a retaining element (7) movable within the rail and adapted to receive and retain the assembly element (2). To provide fixation of the retaining element in the rail, and thereby to enable easier use of the system and use of the system for large components such as for wind turbine nacelle assemblies, the system further comprises a locking element (8) which can be inserted in the slot (5) to prevent movement of the retaining element (7) relative to the structural element (3). The invention further provides a wind turbine including the assembly system.
