Abstract: The present disclosure relates to drive train assemblies for a wind turbine. These assemblies may comprise a rotor hub and a generator module. The generator module comprises a generator stator, and a stationary frame for supporting the generator stator. The generator further comprises a generator rotor, a shaft for supporting the generator rotor, and a bearing assembly for rotatably mounting the shaft on the stationary frame. The shaft is removably connected to the generator rotor, and the bearing assembly comprises a front bearing and a rear bearing. An upwind end of the generator module is attached to a downwind end of the rotor hub. The present disclosure further relates to wind turbines including such wind turbine assemblies and to methods for assembling drive train assemblies.

Abstract: The present disclosure relates to methods and tools for assembling a hub and a generator for a wind turbine, and more particularly to methods and tools for assembling a hub, a generator and a main frame for a direct-drive wind turbine. A method comprises providing a wind turbine hub, a generator and a main frame. The method further comprises vertically moving at least one of the hub and the generator towards the other of the hub and the generator; attaching the hub and the generator to form a hub-generator assembly; turning the hub-generator assembly while gripping the wind turbine hub; and attaching the hub-generator assembly to the main frame.

Abstract: The present disclosure relates to an assembly comprising a rotor hub, a generator rotor, and a shaft for supporting the generator rotor on a stationary frame, wherein the rotor hub is configured to be removable from the generator rotor and the shaft without disassembling the generator rotor from the shaft. The present disclosure further relates to methods for assembly.

Abstract: A hub assembly or a rotor of a wind turbine includes a hub having openings to connect rotor blades thereto. The hub assembly includes a pitch bearing (3) and a pitch carrier positioned between the hub and the pitch bearing, the pitch carrier configured to support a pitch system for adjusting a blade pitch of the rotor blades. The pitch carrier includes a strip plate arranged between two opposite regions of a perimeter of the opening. A mounting structure attaches the strip plate to the hub.

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).

Abstract: It comprises a body that has an inertial asymmetrical and/or the body is asymmetrical in terms of geometry and/or mass of with respect to a XZ plane passing substantially through the centre of a wind turbine rotor for withstanding asymmetrical loads acting on the wind turbine. The inertia in sections of the structural member body at one side of the XZ plane may be 50% greater than the inertia in sections of the structural member body at another side of the XZ plane. The structural member may connect the wind turbine tower with the wind turbine rotor and may comprise at least two asymmetrical portions defined on both sides of the XZ plane which may be mutually asymmetrical reinforcing elements.
