Abstract
A planetary gear system includes a plurality of planet gears, each having a journal bearing and a pin, end supported in a planet carrier. Each pin has a small diameter central portion axially extending for end support. A larger diameter outer portion is integral with the central portion at an inboard merged zone, and has cantilever sections extending outboard from the merged zone. Each pin is sized such that bending of the merged zone in one direction is countered by bending of the cantilever sections in the other direction to achieve a substantially linear bearing surface under load.
