    Abstract: A hub (1) for a wind turbine and a method for fabricating the hub (1) are disclosed. The hub (1) comprises a continuous shell forming a hollow body with a main shaft flange (4) adapted to connect the hub (1) to a main shaft,and one or more blade flanges (5), each blade flange (5) being adapted to connect the hub (1) to a wind turbine blade. The hub (1) further comprises at least two hub parts (2, 3, 7), each hub part (2, 3, 7) being casted separately from a castable material, and each hub part (2, 3, 7) being subsequently connected to at least one other hub part (2, 3, 7) via one or more connecting portions (6), so that at least one blade flange (5) and/or the main shaft flange (4) comprises a section forming part of or being attached to one of the hub parts (2, 3, 7) and a section forming part of or being attached to another hub part (2, 3, 7), thereby ensuring that the casted parts have a size and a weight which are manageable during the manufacture, in particular during the casting. The hub (1) may comprise one or more reinforcement elements arranged at or near the blade flange(s) (5), e.g. comprising an inner wall (8) arranged at a distance to the continuous shell, thereby forming a cavity (9) between the inner wall (8) and the continuous shell. This allows the regions between the blade flanges (5) to be small or narrow, thereby reducing the size and weight of the hub (1), while maintaining a sufficient strength and stiffness of these regions.

    Abstract: The invention relates to a wind turbine blade (5) comprising one or more oscillation dampers (11) for damping oscillations or vibrations of the wind turbine blade (5). The dampers (11) comprise one or more first damper parts (13) having one or more first damper part surfaces (17). The first damper parts (13) being rigidly connected to the blade (5) and/or being a part of the blade (5). The dampers (11) further comprise one or more second damper parts (12) having one or more second damper part surfaces (18), wherein the first damper part surfaces (17) and the second damper part surfaces (18) are arranged to move relatively to each other during the oscillations. Even further the dampers (11) comprise a load transferring coupling (32), directly or indirectly coupling the first damper part surfaces (17) and the second damper part surfaces (18), so that the relative movement result in a oscillation-damping dissipation of kinetic energy. The invention further relates to a wind turbine (1), an oscillation damper (11), a method for damping oscillations of a wing turbine blade (5) and use hereof.

    Abstract: A gearbox for a wind turbine. The gearbox includes at least one first epicyclical gear stage, at least one second gear stage, and a torque transferring shaft including a shaft part and a connection part, wherein the torque transferring shaft is adapted for connecting a first gear of the first epicyclical gear stage with a second gear of the second gear stage and wherein the torque transferring shaft is connected to the second gear stage via the connection part to form a torque-transferring connection area between the connection part and the second gear stage and wherein the outer diameter of the shaft part of the torque transferring shaft is smaller than an inner diameter of the connection area between said torque transferring shaft and said second gear stage.

    Abstract: A method and apparatus for applying a layer of material to a leading edge of a wind turbine blade. The apparatus comprises: a flexible substrate capable of supporting the layer of material, the flexible substrate being reconfigurable between convex and concave configurations; and a support structure for supporting the flexible substrate in the concave and convex configurations. The flexible substrate and support structure are configured such that in use, with the flexible substrate in the convex configuration, the layer of material can be offered up to the leading edge of the wind turbine blade in a convex form to define an initial area of contact between the layer of the material and the leading edge, and thereafter the flexible substrate can be reconfigured into the concave configuration by increasing the area of contact between the layer of material and the leading edge, such that the layer of material is applied to, and adopts the contours of, at least a portion of the leading edge.
