Abstract
A gear set for a generator includes a first gear having a first set of involute teeth and a second gear having a second set of involute teeth circumferentially located about a center axis of rotation. Each set of involute teeth includes respective roll angles, εA-D. For a diametrically smaller one of the first gear and the second gear the roll angle εA is 1.51°-3.51°, the roll angle εB is 7.64°-9.64°, the roll angle εC is 26.03°-28.03°, and the roll angle εD is 32.16°-34.16°, and for a diametrically larger one of the first gear and the second gear the roll angle εA is 15.02°-17.02°, the roll angle εB is 16.7°-18.7°, the roll angle εC is 21.73°-23.73°, and the roll angle εD is 23.41°-25.41°.
