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: An inner bearing race has a body extending from a first end to a second end. An inner bearing race surface defined between a pair of lands extends radially outwardly of the inner bearing race surface, with one of the lands extending to the second end. The bearing race surface is defined by inner face surfaces of the lands. The inner bearing race surface extends for an axial distance between the inner facing surfaces along a central axis C of the body and defines a first distance. A second distance defines an outer diameter 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 0.20 and 0.30. An integrated drive generator and a method are also disclosed.

Abstract: An assembly comprises a resistor support housing for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor support housing for passage of a shaft of an electrical machine. The resistor support housing defines a main annular body around the shaft bore. An end housing is mounted to one axial end of the resistor support housing. The end housing defines a portion of the shaft bore therethrough.
