Abstract: The invention provides a hub for a wind turbine, the hub comprising a continuous shell being assembled from at least two shell parts. To improve stiffness of the hub, a plate element is attached within blade flanges of the assembled hub. Due to the combination between shell parts and a plate element, manufacturing and transportation is facilitated while strength and rigidity is ensured.

Abstract: The invention relates to a bearing with at least one row of rolling elements, where at least one of said at least one row of rolling elements comprise a plurality of first rolling elements adapted for substantially transferring axial forces, and a plurality of second rolling elements adapted for substantially transferring radial forces. To minimize friction, at least one of said at least one row of rolling elements comprises means for separating rolling elements, wherein said means for separating rolling elements comprises one or more cages for retaining said rolling elements, where said one or more cages comprise a pocket adapted for allowing the rolling element to be displaced in the longitudinal direction of said row of elements. The invention also relates to a method for transferring forces through a bearing of a wind turbine.

Abstract: A method of starting up wind turbine (10) comprises heating first and second components, the first component (32) having a first minimum operating temperature and the second component (42) having a second minimum operating temperature. Heat loss is generated after the second component has been heated to the second minimum operating temperature. The heat loss is transferred to the first component to assist heating the first component to the first minimum operating temperature. The first and second components are cooled after reaching the first and second minimum operating temperatures.
