Abstract: A yawing system for a wind turbine with a tower construction and a nacelle includes a stationary part associated with the tower construction, and a rotating part being associated with the nacelle. The rotating part is allowed to rotate relative to the stationary part via a gear connection. The rotating part includes a plurality of modules, each having a sub-module, the sub-modules substantially identical in size and shape. Each module is configurable to perform various functions 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. 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.

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.
