Abstract
Aspects of the disclosure are directed to a gear comprising: gear teeth, a cone wall having an interior surface that forms a chamber, where the gear teeth extend circumferentially from a distal end of the cone wall, a dam that extends radially inward on the interior surface and is axially disposed between the cone wall and the gear teeth, and at least one aperture formed in the cone wall to allow fluid on the interior surface to exit the chamber, where the at least one aperture is located a first distance from the gear teeth along a length of the gear and the dam is located a second distance from the gear teeth along the length of the gear, and where the first distance is greater than the second distance.
