An end winding support segment for a generator rotor includes a support segment body with a curved inner surface configured to be adjacent to a rotor shaft, a winding support arm extending radially outward from the support segment body, and an orifice extending from the curved inner surface of the support to an exterior surface of the support adjacent the winding support arm with the orifice configured to transfer lubricant from a surface of the rotor shaft to a winding located on the winding support arm.

A wedge for use in a generator rotor includes a wedge body extending for an axial length and having a generally triangular cross-section, a first side of the wedge body extending for the axial length of the wedge body, a second side of the wedge body extending for the axial length of the wedge body and having a generally flat surface, a third side of the wedge body extending for the axial length of the wedge body and having a generally flat surface, a first arm extending circumferentially away from the wedge body at an interface between the first side and the second side and extending axially along the wedge body, and a second arm extending circumferentially away from the wedge body at an interface between the first side and the third side and extending axially along the wedge body.

A carrier shaft set includes an input carrier shaft portion and a carrier shaft portion. The input carrier shaft portion has an input carrier shaft portion axis defined between a planetary gear set end and an input shaft end having an outer surface. The input carrier shaft portion includes a wedge-shaped member having an outer edge. A ratio of a length defined between the input carrier shaft portion axis and the outer edge to the outer surface is between 1.23 and 1.30. The carrier shaft portion has a carrier shaft portion axis defined between a planetary gear set end and a shaft end. The carrier shaft portion includes a shaft portion having an outer surface and a wedge-shaped member having an outer edge. A ratio of a length defined between the carrier shaft portion axis and the outer edge to the shaft portion outer surface is between 1.23 and 1.30.
