    摘要： A reduction gearbox is provided that includes a planetary gear arrangement disposed in a casing. The planetary gear arrangement includes a sun gear, planet gear assemblies, and a fore and aft ring gears. The sun gear is configured in communication with a cantilevered end of an input. Each planet gear assembly has a main gear meshed with the sun gear, a fore lateral gear and an aft lateral gear disposed on opposite sides of the main gear and rotating therewith. The main gear has a main gear pitch diameter and the fore and aft lateral gears have a lateral gear pitch diameter. The fore ring gear is meshed with the fore lateral gears. The aft ring gear is meshed with the aft lateral gears. The aft ring gear is independent of the fore ring gear. The planet gear assemblies are in communication with an output.

    摘要： A reduction gearbox (38) is provided that includes a planetary gear arrangement (42) disposed in a casing (44) and a lubrication handling system (96). The planetary gear arrangement (42) includes a sun gear (46), planet gear assemblies (48), and independent fore and aft ring gears (50A, 50B). Each planet gear assembly (48) has fore and aft lateral gears (60, 62) respectively disposed on opposite sides of a main gear (58) and rotating therewith. The main gear (58) has a main gear pitch diameter (P DMG ) and the fore and aft lateral gears (60, 62) having a lateral gear pitch diameter (P DLG ). The fore ring gear (50A) is meshed with the fore lateral gears (60). The aft ring gear (50B) is meshed with the aft lateral gears (62). The planet gear assemblies (48) are in communication with an output (40). The lubrication handling system (96) includes a fore ring gear baffle (98A) and an aft ring gear baffle (98B).
