Planet gear journal for an epicyclic gear system |
| 摘要 |
<p>A planet gear journal (62) for an epicyclic gear system (46) is asymmetrically formed to compensate for carrier twist. The asymmetry may be between a pair of opposed outwardly open annular channels (100,102) inboard of a bearing surface (64) of the journal (62). A particular application is the planetary gear system of a geared turbofan engine.</p> |
