Title:
MULTI-DIRECTIONAL GEARBOX DEFLECTION LIMITER FOR GAS TURBINE ENGINE
Document Type and Number:
Japanese Patent JP2017089615
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide 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.SOLUTION: The gas turbine engine 10 also includes a coupling system 47 for mounting the gearbox 46 within the gas turbine engine 10. The coupling system 47 includes a flexible coupling connected to at least one of a fan frame and a core frame, and 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 an axial range of motion, a radial range of motion and a circumferential range of motion between the gearbox 46 and the frame to which the flexible coupling is attached.SELECTED DRAWING: Figure 1
