EPICYCLIC GEAR TRAIN OF AIRCRAFT POWERPLANT

An epicyclic gear train (12) of an aircraft powerplant includes a sun gear (32) having a rotation axis (RA), a ring gear (34), a plurality of intermediate gears (36) circumscribed by the ring gear (34) and meshed with the sun gear (32) and the ring gear (34), a carrier (38) supporting the intermediate gears (36), and a torque frame (40) attaching the carrier (38) to a stationary structure (42) of the aircraft powerplant to prevent rotation of the carrier (38) and of the intermediate gears (36) about the rotation axis (RA) of the sun gear (32). The torque frame (40) is attached to the carrier (38) at a connection. The torque frame (40) and the carrier (38) cooperatively define a lubricant passage (78, 82, 84) extending through the connection and supplying lubricant to at least one of the intermediate gears (36).
