ABSTRACT:
A planet gear journal for an epicyclic gear system is asymmetrically formed to compensate for carrier twist. The asymmetry may be between a pair of opposed outwardly open annular channels inboard of a bearing surface of the journal. A particular application is the planetary gear system of a geared turbofan engine.
