Abstract
A gear reduction gearbox connected to a gas turbine engine to reduce the shaft speed and increase the output torque. In one form of the present invention an input shaft and an output shaft are rotatable within a mechanical housing. A face gear set connects between the shafts for changing the speed of the output shaft relative to the input shaft. The present invention, in one embodiment includes load sharing wherein a plurality of pinion gear assemblies distribute the load transmitted through the gearbox.
