Patent ID: 8578807

Claim:
A gear comprising: a body, the body having a first side, a second side opposite the first side and a surface extending between the first and second sides; and a plurality of teeth extending from the surface, each tooth of the plurality of teeth having a base portion adjacent to the surface of the body and a distal portion that defines a tip of the tooth, each tooth has a first side adjacent to the first side of the body and a second side adjacent to the second side of the body; a plurality of first extended portions, the first side of each tooth of the plurality of teeth being attached to a respective one of the first extended portions such that that extended portion extends beyond the first side of the body to divert a flow of fluid adjacent to the first side of the body to reduce windage losses that occur when the gear rotates; and wherein the first extended portions are each comprised of a structure defining a ramp that is integrally attached to the tooth to which that first extended portion is attached, the ramp defining a first outer surface that extends outwardly along a length from a middle portion of the first side of the tooth to which the first extended portion is attached to an outer edge and a second surface that extends inwardly from the outer edge to the first side of the tooth to which the first extended portion is attached, the first outer surface being opposite the second surface, the first outer surface being curved, flat or substantially flat, the second surface extending collinearly to a front or a rear of the tooth, the outer edge being adjacent the rear or the front of the tooth and positioned outwardly from the first side of the tooth.
