Embodiment Construction

[0035] figure 1A wind turbine 14 is shown schematically with a support platform 3 facilitating access to the interior 4 . Said interior is delimited by the outer surface of a rotor hub 1 which transmits torque towards a generator 15 which is arranged stationary within a nacelle 16 of a wind turbine 14 . A plurality of rotor blades 12 are connected to the rotor hub 1 . The spinner shroud 4 is rigidly connected to the rotor hub 1 and thus rotates with the rotor hub 1 during operation of the wind turbine 14 .

[0036] figure 2 A perspective front view of a rotor hub 1 and a spinner cowl 2 according to a first embodiment of the invention is shown. The rotor hub 1 is covered by a spinner cowl 2 which has been partly removed for illustration purposes. A plurality of support platforms 3 are placed in an interior 4 provided between the rotor hub 1 and the spinner case 2 . The support platform 3 is arranged circumferentially around a central access opening 5 providing access from...

Abstract

A wind turbine (14) with at least one support platform facilitating access within an interior (4) that is disposed in the interior (4) bounded by an outer surface of a rotor hub (1) and an inner surface of a spinner cover(2) and firmly secured to at least one of the rotor hub (1) and the spinner cover (2), wherein the support platform (3) comprises at least one flat section (10) for providing secure access within the interior (4) of the rotor hub (1).

Description

technical field [0001] The invention relates to a wind turbine having at least one support platform facilitating access to the interior. Background technique [0002] Wind turbines need to be constantly accessible by maintenance personnel for maintenance purposes. Of particular importance is the access to the interior delimited by the outer surface of the rotor hub on which the plurality of rotor blades are mounted and the inner surface of the spinner shroud of the wind turbine. A rotor hub is rotatably mounted relative to the nacelle. The spinner cowl is rigidly connected to the rotor hub and thus rotates together with respect to the nacelle during operation of the wind turbine. [0003] Rotational energy can be transferred directly or indirectly to the generator. Indirect transmission can be achieved through a gearbox arranged between the generator and the rotor hub. In particular, the main bearings that rotatably support the rotor hub carry large loads during operatio...
