Carrier for planetary gear system

A carrier for a planetary gear system comprising:

• a first wall having spaced apart interior lateral surfaces with circumferentially spaced bores extending through the first wall, a second wall spaced apart from and parallel to the first wall, the first and second walls including axial pairs of circumferentially spaced bores, each pair of bores configured to support a rotationally fixed journal bearing on which a gear is mounted for rotation, and a scupper arranged between the lateral surfaces and providing an inlet in one of the lateral surfaces, the inlet having a first circumferential dimension, and a passage fluidly interconnecting the scupper to one of the bores, the passage having a second circumferential dimension less than the first circumferential dimension, the journal bearing including an axially extending inner feed passage in fluid communication with the passage and the scupper;
• a bushing arranged in the bore between the first wall and the journal bearing, the bushing and journal bearing respectively including first and second passageways fluidly connecting the passage in the carrier and the feed passage to one another;
• and
• an alignment feature rotationally fixing the journal bearing and the bushing relative to the carrier.
