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