Abstract
A planetary gear system including a first gear coupled to a shaft, a plurality of second gears in rotational engagement with the first gear, a fluid supply apparatus spaced apart from the second gears, and a carrier. The carrier includes an annular portion having a flow channel configured to receive a fluid deposited onto the carrier by the fluid supply apparatus. A pinion shaft is disposed through each of the second gears and includes a primary fluid conduit in fluid communication with the flow channel and at least one secondary fluid conduit in fluid communication with the primary fluid conduit. The primary fluid conduit and the at least one secondary fluid conduit facilitate a flow of the fluid from the flow channel to at least one bearing disposed on each of the pinion shafts and at least one thrust plate interposed between the second gears and the carrier.
