Abstract: A gearbox for a gas turbine engine includes a housing that includes first and second housing portions interconnected by an intermediate housing portion to provide a generally U-shaped structure. Each of the first and second housing portions includes opposing first and second faces. The second faces of the first and second housing portions are adjacent to one another. First and second gear sets are respectively arranged in the first and second housing portions. A third gear set is arranged in the intermediate portion and is coupled to the first and second gear sets. Accessory drive component mounts are provided on at least three of the first and second faces of the first and second housing portions. The mounts are each configured to support an accessory drive component coupled to one of the first and second gear sets.

Abstract: An accessory system for a gas turbine engine includes an accessory gearbox which defines an accessory gearbox axis and includes first and second sides. A first geartrain includes one or more shafts rotatable about axes perpendicular to the first side of the accessory gearbox and a second geartrain includes one or more shafts rotatable about axes perpendicular to the second side of the accessory gearbox. A driven gear set defines an input axis and drives first geartrain and the second geartrain about corresponding first and second drive axes parallel to the input axis.
