Abstract

A planetary gear system, 46, includes a sun gear, 48, rotatable about an axis. Planetary gears, 50, are circumferentially arranged about and intermesh with the sun gear, 48, and peripherally with a ring gear. Each of the planetary gears, 50, is supported by a journal bearing, 60, arranged in a bore in a carrier wall. A carrier, 52, supports the journal bearings, 60, and is configured to rotate about the axis and carry the planetary gears. The carrier wall supports the journal bearings and has spaced apart lateral surfaces. A scupper, 74, is arranged between the lateral surfaces, 84, 86, and provides an inlet, 88, in one of the lateral surfaces, in this example facing the sun gear, 48. The inlet, 88, has a first circumferential dimension, and a passage, 90, fluidly interconnects the scupper, 74, to one of the journal bearings via the bore. The passage has a second circumferential dimension less than the first circumferential dimension.
