    Abstract: A method of mounting a gear train to a torque frame includes providing a unitary carrier having a central axis that includes spaced apart walls and circumferentially spaced connecting structure defining mounts for interconnecting the walls. Spaced apart apertures are provided between the mounts at an outer circumference of the carrier. Gear pockets are provided between the walls and mounts extending to the apertures, and a central opening in at least one of the walls. A plurality of intermediate gears and a sun gear are inserted in the carrier. A first ring gear half is placed about the outer periphery of the intermediate gears, and attach a torque frame to the carrier.

    Abstract: An engine comprises a gear system and a coupler. The gear system comprises a sun gear, a ring gear, and a plurality of intermediate gears that engage the sun and ring gears. The coupler is for connecting the gear system to an engine static structure. The coupler is configured to limit deflection of the gear system. Two of the sun gear, the ring gear, and the plurality of intermediate gears are configured to rotate and/or orbit about a central axis. The third of the sun gear, the ring gear, and the plurality of intermediate gears is connected to the coupler and is configured not to orbit and/or rotate relative to the central axis.
