    Abstract: A sealing apparatus for rotational equipment includes an annular seal plate rotatable around an axis. The annular seal plate includes an annular seal land surface, an internal plenum, a plurality of inlet passages, a plurality of cooling passages and a plurality of outlet passages. The inlet passages are arranged about the axis. Each of the inlet passages extends into the annular seal plate to the internal plenum. The cooling passages are arranged about the axis. Each of the cooling passages extends into the annular seal plate from the annular seal land surface to the internal plenum. The outlet passages are arranged about the axis. Each of the outlet passages extends into the annular seal plate to the internal plenum. The outlet passages are arranged radially between the inlet passages and the cooling passages.

    Abstract: A gear assembly is provided. The gear assembly includes a first gear that rotates about a first axis and includes a first gear face with a plurality of first gear teeth; a second gear that rotates about a second axis and includes a second gear face with a plurality of second gear teeth, where the first axis is not parallel with the second axis and the first and second teeth rotatably engage as the first gear rotates about the first axis and the second gear rotates about the second axis; a scraper that includes a distal interference surface in face-to-face proximity with at least one of the first plurality of teeth as the first gear rotates about the first axis, where the interference surface removes oil entrained adjacent to the plurality of first or second gear teeth as the first or second gears rotate.

    Abstract: A squeeze film damper bearing assembly includes a bearing and a squirrel cage radially outward of and supporting the bearing. The squirrel cage includes a first piston ring groove, a second piston ring groove, and a first pocket connected to the first piston ring groove. The squeeze film damper bearing assembly also includes a first piston ring configured to fit into the first piston ring groove. The first piston ring includes a first end circumferentially spaced apart from a second end and an ear configured to fit into the first pocket to prevent the first piston ring from rotating in the first piston ring groove. The squeeze film damper bearing assembly also includes a second piston ring configured to fit into the second piston ring groove and a stationary housing radially outward of the squirrel cage.

    Abstract: A bearing compartment assembly for a gas turbine engine includes an intermediate case, a towershaft, a shaft, a bull gear, a bevel gear, a towershaft bearing, and a support mount. The intermediate case includes a plurality of struts distributed circumferentially about a centerline axis. The towershaft extends through one of the struts. The shaft passes through a center of the intermediate case and extends along the centerline axis. The bull gear is connected to and extends axially from the shaft. The bevel gear is mounted to an end of the towershaft and is engaged with the bull gear. The towershaft is connected to the shaft via the bull gear and the bevel gear. The towershaft bearing surrounds and is operably connected to the towershaft. The support mount is connected to the intermediate case and extends from a surface of the intermediate case to the towershaft bearing.
