Air-cooled generator rotor with improved wedges

摘要

A wedge for use in a generator rotor has a wedge body with a central radially top surface of the wedge body, formed with a plurality of blades. At least some of the plurality of blades extend at an angle such that a plane defined through the blades will be non-perpendicular to a rotational axis of the rotor that will receive the wedge.

主权项

1. A wedge for use in a generator rotor comprising:
a wedge body having a central radially top surface, when the wedge is mounted in a generator, a plurality of blades formed on said central radially top surface, at least some of said plurality of blades extending along an angle that will be non-perpendicular to a rotational axis of the rotor that will receive the wedge; said wedge body has flat circumferential sides; and said flat circumferential sides extend to a location that will be radially outward of a radially outermost portion of said blades, when the wedge is mounted in a rotor.
