Multi-directional gearbox deflection limiter for a gas turbine engine

A gear train for a gas turbine engine defining an axial direction, a radial direction, and a circumferential direction, the gear train comprising:

• a sun gear rotatable by a shaft of the gas turbine engine;
• a ring gear attachable to a ring gear shaft;
• a plurality of intermediate gears rotatably mounted in a gear carrier and meshing with the sun gear and ring gear;
• and
• a coupling system comprising
• a flexible coupling for connection with a nonrotating component of the gas turbine engine;
• a torque frame connected to the flexible coupling and the gear carrier for connecting the flexible coupling to the gear carrier;
• and
• a deflection limiter loosely attaching the flexible coupling to the gear carrier, the deflection limiter providing for an axial range of motion, a radial range of motion, and a circumferential range of motion between the gear carrier and the nonrotating component to which the flexible coupling is attached;
• the deflection limiter comprising a first channel and a second channel that together providing at least in part the axial range of motion, the radial range of motion, and the circumferential range of motion between the gearbox and the frame to which the flexible coupling is attached, wherein the first channel includes a first lip defining a first slot, wherein the second channel includes a second lip defining a second slot, wherein the first lip of the first channel is positioned in the second slot of the second channel and the second lip of the second channel is positioned in the first slot of the first channel.
