Oil baffle for gas turbine fan drive gear system

A method of assembly for a gas turbine engine comprising the steps of:

• assembling an epicyclic gear train including:
• positioning a carrier, the carrier including spaced apart side walls and circumferentially spaced mounts interconnecting the side walls, wherein circumferentially spaced apart apertures are established between the mounts at an outer circumference of the carrier, a plurality of intermediate gear pockets are established between adjacent pairs of the mounts, and at least one of the side walls includes a central opening, the carrier is a unitary structure with the side walls and the mounts unitary with one another;
• inserting intermediate gears through the central opening of the carrier and into a central gear pocket;
• moving each of the intermediate gears radially outward from the central gear pocket into a respective one of the intermediate gear pockets relative to an axis of the carrier, and then through a respective one of the apertures;
• inserting a plurality of baffles into the carrier in a space between the walls subsequent to the moving step, and securing the baffles to at least one of the side walls and to a respective one of the mounts, wherein the intermediate gear pockets are established between adjacent pairs of the baffles, and the baffles include respective lubrication passages;
• inserting a sun gear through the central opening and into the central gear pocket;
• moving each of the intermediate gears radially inward relative to an axis of the carrier subsequent to the step of inserting the sun gear such that the intermediate gears are arranged about and intermesh with the sun gear;
• and
• moving a ring gear into engagement with the intermediate gears such that the ring gear intermeshes with the intermediate gears;
• securing a torque frame to the mounts;
• fixedly attaching the torque frame to a housing;
• coupling the gear train to a turbo fan shaft;
• and
• supporting a turbo fan on the turbofan shaft.
