Abstract
Methods and systems are provided for lubrication of a transmission. In one example, the transmission system may include a pair of shielded bearings attached to a first transmission shaft, each of the shielded bearings including at least one shield that forms a restriction between the shield and a race of the bearing and a cavity positioned axially between the pair of shielded bearings, wherein the restrictions tune lubricant pressurization in the cavity. The transmission system further includes a radial passage in the first transmission shaft in fluidic communication with the cavity and a lubricated transmission component.
