Beschreibung
Zusammenfassung:	A planet gearbox has a planet gear rotatable on a planet bearing that includes an inner ring that is mounted to a carrier of an epicyclic gearing arrangement. A respective cylindrical inner surface of each opposite respective end of the inner ring is non-rotatably connected to a respective cylindrical outer surface of a respective one of a pair of support plugs that are fixed to the carrier of the epicyclic gearing arrangement. A gas turbine engine includes a fan and LP shaft, which couples a compressor to a turbine. An epicyclic gearing arrangement has a single input from the LP shaft coupled to a sun gear, a single output coupled to the fan's shaft, and at least one planet bearing as described above.
