Abstract
A rotor drive generator drive gear for an integrated drive generator can include an annular body having an outer diameter and an inner diameter defining an inner diameter channel through the body in a direction of an axis of rotation of the annular body. The annular body can define a gear defined on the outer diameter of the annular body and a bearing race defined on the outer diameter of the annular body. The bearing race can include a bearing race channel and one or more race relief channels defined from the bearing race channel at least partially inwardly toward the inner diameter channel. One or more lubrication conduits are defined through the body to fluidly connect the inner diameter opening and the bearing race such that lubricant can travel from the inner diameter channel to the bearing race for providing lubrication to a bearing assembly disposed in the bearing race.
