Abstract: A lubrication system for a gas turbine engine includes a tank, a circulation pump, and a heat exchanger. The circulation pump generates a flow of lubricant from the tank to, e.g., a power gear box of the gas turbine engine and the heat exchanger removes an amount of heat from such flow of lubricant provided to the power gear box. The lubrication system also includes one or more valves in the flow of lubricant for controlling a flowrate and/or temperature of the lubricant provided to, e.g., the power gear box to increase an efficiency and/or durability of the power gear box.

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 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 gas turbine engine including a fan, a core including at least one rotatable shaft, and a gearbox mechanically coupling at least one rotatable shaft of the core to the fan is provided. The gas turbine engine also includes a coupling system for mounting the gearbox within the gas turbine engine. The coupling system includes a flexible coupling connected to at least one of a fan frame or a core frame, as well as a torque frame connected to the flexible coupling and the gearbox. Moreover, a deflection limiter is provided, loosely attaching the flexible coupling to the gearbox to provide a predetermined axial range of motion, radial range of motion, and circumferential range of motion between the gearbox and the frame to which the flexible coupling is attached.
