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.
