Embodiment Construction

[0027] The legends in the figures are schematic. It is to be noted that in different figures, similar or identical elements are provided with the same reference signs.

[0028] Figure 1 to Figure 4 A partial representation of a wind turbine 100 is shown, comprising a hub 10 according to the invention and three blades 101 , 102 , 103 attached to the hub 10 .

[0029] The hub 10 extends longitudinally along a longitudinal axis Y between a front end 11 and a rear shaft circular flange 12 connectable to a hollow rotating shaft (not shown) of the wind turbine 100 .

[0030] In particular, the longitudinal axis Y may coincide with the axis of the rotation shaft of the wind turbine 100 and thus with the rotation axis of the turbine rotor.

[0031] The terms "axial" or "longitudinal", "radial" and "circumferential" hereinafter are made with reference to the longitudinal axis Y, when not specified differently. Thus, the blades 101 , 102 , 103 extend radially with respect to the axi...

Abstract

The present invention relates to a hub and spinner for a wind turbine. A hub (10) for a wind turbine (100) is longitudinally extended along a longitudinal axis (Y) between a front tip (11) and a rearshaft flange (22). The hub (10) comprises: at least one blade flange (15) for connecting a respective blade (101, 102, 103) to the hub (10); at least one top edge (16) on an external surface (20) of the hub (10), the top edge (16) being positioned with respect to a vertical direction over the front tip (11), when the hub (10) is positioned in a service position; a plurality of service steps (30),each step (30) being oriented for permitting an individual to move between the front tip (11) and the top edge (16) or between the rear shaft flange (12) and the top edge (16) when the hub is positioned around the longitudinal axis (Y) in the service position.

Description

technical field [0001] The invention relates to a hub for a wind turbine. Furthermore, the invention also relates to a hub and spinner assembly for a wind turbine. Background technique [0002] In the technical field of wind turbines, components are becoming larger and larger. In particular, this is also the case for the main shaft of a wind turbine, and thus for the hub attached to this main shaft. [0003] Maintenance tasks need to be performed in the area between the hub and the hub shell, such as replacement of the blade bearing connection, the hub connection or the outer seal of the blade bearing, etc. To do this, a service technician needs to be in the area between the hubcap and the machined hub. Due to the large size of some hubs, it is difficult for a technician to reach the areas of the hub or hubcap associated with the above-defined repair tasks. [0004] Therefore, in wind turbines, there is a need to provide an improved design for the hub and for the assembl...
