Abstract
A high ratio epicyclic gear train (A) with improved load carrying capability for transmitting power from a driven input shaft, such as may be driven by a turbine engine or engines, to a output shaft, as may be coupled to a rotor of a rotary wing aircraft. The compound epicyclic gear train incorporates a load sharing mechanism consisting of a drive sun gear (10), an idler sun gear (11), a ring gear (12), a set of drive planet gear assemblies (13), a set of idler planet gear assemblies (14), and a planet carrier assembly (15) coupled to provide at least two power pathways through said epicyclic gear train (A) between said driven input shaft and said output shaft to provide an improved overall power density of the transmission.
