Abstract

A gear system (48) for a turbofan engine assembly includes a sun gear (62) rotatable about an engine centerline, a non-rotatable ring gear (68), a rotating carrier (66) that drives a fan (42), and a plurality of planet gears (64) intermeshed between the sun gear (62) and the ring gear (68). Each of the plurality of planet gears (64) supported on rolling element bearings (78) fit into the carrier (66). Each of the plurality of planet gears (64) includes an inner cavity (76) and a lubricant passage (126) directed at the rolling element bearings (78). The carrier (66) includes an outer scoop (84) that receives lubricant from an outer fixed lubricant jet (86) and feeds lubricant into the inner cavity (76) and through the lubricant passage (126) to spray lubricant on to the rolling element bearings (78).
