Abstract
A planet gear carrier assembly has a cage in which is rotatably mounted a plurality of pinion gears. Each gear is mounted on a respective spindle which is disposed in aligned bores formed in the sidewalls of the cage. In one sidewall, the bores have a stepped diameter to limit longitudinal movement of the spindles in one direction. A flat machined on each spindle and a locking ring, secured in a groove in the other sidewall limit longitudinal movement of the spindles in the other direction as well as rotary movement of the spindles. In one embodiment, an oil shield or lube directing ring is positioned by the locking ring and the spindle flat to direct lubrication fluid to lube passages formed in the spindles.
