Embodiment Construction

[0053] In these figures, the same reference numerals are used to identify matching elements.

[0054] figure 1 A perspective view of one example of a wind turbine 160 is illustrated. As shown, wind turbine 160 includes a tower 170 extending from support surface 150 , a nacelle 161 mounted on tower 170 , and rotor 115 coupled to nacelle 161 . Rotor 115 includes a rotatable hub 11 , and at least one rotor blade 120 coupled to and extending outwardly from hub 11 . For example, in the illustrated example, rotor 115 includes three rotor blades 120 . However, in alternative embodiments, rotor 115 may include more or less than three rotor blades 120 . Each rotor blade 120 may be spaced from hub 11 to facilitate rotating rotor 115 to enable kinetic energy to be converted from wind power into usable mechanical energy, and subsequently electrical energy. For example, hub 11 may be rotatably coupled to a generator positioned within nacelle 161 or a shaped part of the nacelle to allow...

Abstract

Hub assemblies (1) for a rotor (115) of a wind turbine (160) are disclosed. The hub assembly comprises a hub (11) comprising openings (12) to connect rotor blades (120), a pitch bearing (3), a pitch carrier (2) positioned between the hub (11) and the pitch bearing (3) and configured to support a pitch system (4) for adjusting a blade pitch, wherein the pitch carrier (2) comprises a strip plate (21) arranged between two opposite regions of the perimeter of the opening (12), and a mounting structure for assembling the strip plate (21) with the hub (11). Also disclosed are methods (200) for manufacturing a hub assembly (1) of a wind turbine (160).

Description

[0001] The present disclosure relates to hub assemblies for rotors of wind turbines, and methods for manufacturing such hub assemblies. Background technique [0002] Modern wind turbines are commonly used to supply electricity into the grid. Wind turbines of this type generally comprise a tower and a rotor arranged on the tower. A rotor, typically comprising a hub and a plurality of blades, is set to rotate under the influence of wind on the blades. The rotation generates torque, which is transmitted to the generator, usually directly through the rotor shaft ("direct drive" or "gearless") or through the use of a gearbox. In this way, the generator produces electricity that can be supplied to the grid. [0003] In a conventional wind turbine, the pitch (or pitch) angle of the blades can be adjusted by an auxiliary drive system in the hub, such as a pitch system, to adjust the load on the blades. Pitch systems typically have a series of components to adjust the pitch angle. ...
