Abstract

A gas turbine engine (20) includes a turbine section (28) having at least one turbine rotor. A compressor section (24) includes at least one compressor rotor, and a propulsor (119). The at least one turbine rotor is connected to drive an epicyclic gear reduction to in turn drive the propulsor (119) at a slower speed than the at least one turbine rotor. The epicyclic gear reduction includes a sun gear (110) for receiving a drive input from the at least one turbine rotor and having gear teeth engaging gear teeth (104) on a plurality of intermediate gears (102). The intermediate gears (102) are mounted within a carrier (112). The teeth (104) on the intermediate gears (102) also engage teeth (106) on a ring gear (100). One of the carrier (112) and the ring gear (100) is connected to drive a propulsor drive shaft (120) to in turn drive the propulsor (119), and the other of the carrier (112) and the ring gear (100) connected to a static structure, with the carrier (112) connected to either the propulsor drive shaft (120) or the static structure through a torque frame (111). The torque frame (111) is connected to the carrier (112) at a radially outer location through a splined connection.
