Abstract: An input shaft includes an annular main shaft extending along a longitudinal axis with an internal bore configured for fluid flow through the annular main shaft. A generator spline is included on an exterior surface of a first end of the main shaft. A gearbox spline is included on an exterior surface of a second end of the main shaft opposite the first end. At least one orifice is defined through the main shaft from the internal bore to the exterior surface of the second end of the main shaft for flow of fluid from the internal bore to the exterior surface for cooling and lubrication.

Abstract: A terminal assembly includes a terminal block of a dielectric material defining a plurality of bores therethrough. A respective terminal contact of an electrically conductive material is seated in each of the respective bores. The terminal contact defines a longitudinal axis therethrough with a terminal bore defined through the terminal contact along the longitudinal axis. A divider wall separates the terminal bore into a solder cup for a lead wire on an interior side of the terminal bore, and a lug receptacle on an exterior side of the terminal bore.

Abstract: A housing for a gas turbine engine accessory includes an enclosure having a drive end with an opening and a closure. The closure is seated in the opening, defines therethrough a shaft aperture and has a v-band flange extending about a periphery of the closure to limit load carried by the enclosure when the engine accessory is mounted to an accessory gearbox mount in a cantilevered arrangement. Engine accessories for gas turbine engines and mounting arrangements for gas turbine engine accessories are also described.

Abstract: A terminal lead support for use in an integrated drive generator has a body defining an outer end extending to two outer angled surfaces. The outer angled surfaces each extend to curved end portions. The curved end portions connect the outer angled surfaces into inner angled surfaces. The inner angled surfaces each extend into cupped portions formed about a radius. There are six apertures formed within the body, with laterally outer apertures spaced from the outer surface by a greater amount than laterally intermediate apertures. The laterally intermediate apertures are spaced from the outer surface by a greater amount than laterally inner apertures. An integrated drive generator and a method of replacing a terminal lead support are also disclosed.

Abstract: A pump sleeve for an integrated drive generator has a pump sleeve body extending between a first end and a second end. The first end is at a location adjacent a radially enlarged end plate. The body extends to the second end with a generally cylindrical body portion having an inner bore diameter defining a first distance. The body extends between the first and second ends for a second distance. A ratio of the first distance to the second distance is between 0.15 and 0.30. An integrated drive generator and a method are also disclosed.

Abstract: A variable block shaft has a radially enlarged disc formed at a first end. A shaft portion extends from the disc to a second end. An inner bearing race surface is defined intermediate the first and second end and has an outer peripheral surface. An axial length of the inner bearing race surface is defined between inner facing surfaces of lands at each axial side. The axial distance is measured along the center axis of the body and an outer diameter to the inner bearing race surface being defined as a first distance. The axial length of the inner bearing race surface is defined as a second distance and a ratio of the first distance to the second distance being between 3.75 and 3.90. An integrated drive generator and a method are also disclosed.
