    Abstract: A wind turbine nacelle including an outer cover defining an interior volume within which is housed a powertrain assembly comprising: a gearbox including an input shaft and an output shaft which are aligned on a common rotational axis, an electrical power generator connected to the output shaft of the gearbox. The power generator includes a generator cabinet that encloses, in an internal chamber, a stator at a radially outward position and a rotor in a radially inward position, the rotor being rotatable about the common rotational axis. The rotor comprises: a cylindrical field structure coupled to a rotor support frame; a gearbox connection flange that couples to the gearbox output shaft by a first fixing array; wherein the generator cabinet is provided with an opening that permits maintenance personal to gain access fully inside the internal chamber, and wherein the internal chamber is configured to allow maintenance personnel to access at least the first fixing array that couples the gearbox output shaft to the gearbox connection flange from a position fully inside the internal chamber.

    Abstract: A wind turbine powertrain assembly including a gearbox coupled to an electrical power generator for a wind turbine. The power generator comprises a stator at a radially outward position and a rotor in a radially inward position, wherein the rotor comprises a cylindrical field structure that is configured to rotate about a generator rotor axis, and wherein the rotor is configured to define a central hollow portion. The rotor further comprises a rotor support frame connected to and structurally supporting the cylindrical field structure, wherein the rotor support frame comprises: a rotor connection flange attaching the rotor support frame to the cylindrical field structure, a gearbox connecting flange connecting the rotor support frame to an output drive shaft of the gearbox, and a transition section extending between the rotor connection flange and the gearbox connection flange, the transition section defined at least in part by one or more stepping regions, the or each stepping region shaped to define a surface that is inclined at an angle of less than 30 degrees to the rotor axis. Advantageously, the stepping regions provide an integrated platform inside the hollow portion on which service personnel can stand to work inside the generator.
