Abstract:
1. A gear support assembly for a turbine engine, comprising: an epicyclic gear arrangement including a plurality of intermediate gears, a carrier supporting the plurality of intermediate gears, a sun gear that meshes with the plurality of intermediate gears and a ring gear surrounding and meshing with the plurality of intermediate gears, the ring gear including an inner periphery with teeth, an outer circumferential surface opposite the teeth, a flange projecting radially outwards from the outer circumferential surface, and a passage operable to convey oil though the ring gear, the passage extending through the flange and opening at the inner periphery and at a radially outer tip of the flange; a gutter configured to collect oil, the gutter being located radially outwards of the flange and the passage opening into the gutter; a seal secured to, and axially flanking, the flange, the seal including a slot configured to permit oil from a side of the ring gear to drain into the gutter; and a first tapered bearing and a second tapered bearing spaced apart from the first tapered bearing, the first tapered bearing and the second tapered bearing being arranged axially forward of the epicyclic gear arrangement and supporting the epicyclic gear arrangement, wherein the first tapered bearing includes a first roller element supported by a first inner race and defining a first rotational axis and the second tapered bearing includes a second roller element supported by a second inner race and defining a second rotational axis such that the first rotational axis and the second rotational axis intersect at a position that is radially inwards from the first inner race and the second inner race.
