An epicyclic gear train includes a sun gear rotatable about a central axis, a concentric outer ring gear, and a plurality of gears mechanically intermediate the sun gear and the ring gear, and which are in meshing engagement therewith. An epicyclic carrier assembly comprises a gear support member and a coupling adapter. The gear support member is adapted to rotatably support the plurality of gears on axles between first and second axle ends. The gear support member has at least a first connecting member. The coupling adapter is disposed concentrically with the gear support member and has a second connecting member. The second connecting member is engaged with the first connecting member to structurally join the coupling adapter and the gear support member. The first and second connecting members are mounted to one another in a plane between the first and second axle ends.
An epicyclic carrier assembly adapted for use in an epicyclic gear train, said gear train including a sun gear rotatable about a central axis, a concentric outer ring gear, and a plurality of gears circumferentially spaced relative to, and mechanically intermediate of, said sun gear and said ring gear and in meshing engagement therewith, said plurality of gears being adapted for receiving torque input from said sun gear, said planetary carrier assembly comprising:
