A gearbox assembly (26) includes a first face gear (52a) driveable about a face gear axis (56) in a first direction (62) by at least one first pinion gear (50a) and a second face gear (52b) driveable about the face gear axis (56) in a second direction (66) opposite the first direction (62) by at least one second pinion gear (50b). A thrust bearing (58) is located between the first face gear (52a) and the second face gear (52b). The first face gear (52a) is configured to drive rotation of a first shaft (22) in the first direction (62) and the second face gear (52b) is configured to drive rotation of a second shaft (20) in the second direction (66). Further disclosed is a power train for a rotary wing aircraft (10) having a gearbox (26) including a first face gear (52a) rotatable in a first direction (62) and a second face gear (52b) rotatable in a second direction (66) opposite the first direction (62).
