Abstract: A static lubricant supply system within a gearbox that delivers lubricant to rotating gears. The lubricant supply system includes a stationary sleeve assembly for delivering the lubricant to a rotating receiver member, shaft, or flange. The sleeve assembly includes bearings, seals, jets, and plenums. The jets are skewed to deliver lubricant in the tangential direction of rotational motion of the receiver member, shaft, or flange. In the radial gap transfer configuration, the sleeve assembly circumscribes the receiver member or shaft. A race in the receiver member or shaft receives the lubricant. Channels within the receiver member, shaft, and gears deliver lubricant to the gears. In the axial gap transfer configuration, the sleeve assembly transfers lubricant to a flange attached to a receiver member. The flange has a race that receives the lubricant from the jets. Channels within the flange, receiver member, and gears deliver lubricant to the gears.

Abstract: A planet gear train for an engine casing includes a sun gear rotatable by a shaft, a ring gear, a plurality of planet gears rotatably mounted in a planet carrier and meshing with the sun gear and the ring gear, and a damping system. The damping system includes a soft mount disposed about the shaft and coupling the planet carrier the engine casing. The soft mount includes a flexible inner sleeve and a flexible outer sleeve. The flexible inner sleeve and the flexible outer sleeve are fixedly coupled together at respective central portions thereof near the shaft. The damping system further includes a plurality of damping couplers disposed about an outer flange of the planet carrier. The plurality of damping couplers is configured to flexibly couple the flexible inner sleeve to the flexible outer sleeve.

Abstract: A planet gear rotatable on a planet bearing with cylindrical rollers is mounted to a carrier of an epicyclic gearing arrangement. Either the cylindrical outer surface of the support pin or the opposing cylindrical inner surface of the inner ring of the planet bearing includes a network of interconnected grooves. The support pin includes oil feed holes intersecting the grooves. Passages through the planet bearing's inner ring also connect to the grooves. A gas turbine engine includes a fan and LP shaft, which couples a compressor to a turbine. An epicyclic gearing arrangement has a single input from the LP shaft coupled to a sun gear, a single output coupled to the fan's shaft, and a planet bearing with a network of interconnected grooves.

Abstract: A planet gear includes a pin and an annular planet gear rim. The pin has a pin radius. The pin includes a pin outer surface. The annular planet gear rim has an inner radius and an outer radius. The annular planet gear rim includes an inner surface and an outer surface. The inner surface and the pin outer surface define a clearance therebetween. The clearance is greater than 0 when a radial force is applied to the planet gear.
