Abstract
An engine includes a static frame member; a spool configured to rotate relative to the static frame member during operation of the engine; a gearbox coupled to the spool; and a gearbox coupling assembly mounting the gearbox to the static frame member using a plurality of moveable connection members, each moveable connection member including a sliding connection allowing for movement of the gearbox relative to the static frame member in a plane perpendicular to an axial direction of the engine.
Claims14
An engine defining an axial direction including a forward direction closer to an engine inlet and an aft direction closer to an engine exhaust, a radial direction, and a circumferential direction, the engine comprising:
- a static frame member;
- a spool configured to rotate relative to the static frame member during operation of the engine;
- a gearbox coupled to the spool;
- a gearbox coupling assembly mounting the gearbox to the static frame member using a plurality of moveable connection members;
- and
- a bearing positioned between the static frame member and the spool at a location forward of the gearbox,
- wherein each moveable connection member allows for sliding movement of the gearbox relative to the static frame member in a plane perpendicular to the axial direction of the engine,
- wherein the engine defines a sump, and
- wherein the bearing and the gearbox are each positioned within the sump.
