Abstract: A wedge for a rotor of an electric machine includes a circumferentially outer surface defining a radial extent of the wedge extending from a first axial end of the wedge to a second axial end of the wedge. A plurality of circumferentially-extending grooves extend radially inwardly from the circumferentially outer surface to a groove depth. The plurality of grooves are axially spaced along a wedge length between the first axial end and the second axial end. The axial spacing between the grooves is greater than an axial width of each groove. An intermediate surface between adjacent grooves has a same radial position as a first end surface between the first axial end and a first groove closest to the first axial end. Two planar side surfaces circumferentially bound the circumferentially outer surface and extend radially inwardly from the cicumferential outer surface.

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: 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.

Abstract: A disconnect plunger for use in an integrated drive generator includes a plunger body extending between a first end and a second end. A cam surface is formed on the second end, and has a cylindrical cam portion extending across the second end. The cylindrical cam portion has a location formed at a radius about a point spaced beyond the second end relative to the first end. A first distance is defined from a second end facing surface of a cylindrical guide portion positioned intermediate first and second end. A ratio of the first radius to the first distance is between 0.15 and 0.30. The point is spaced in a direction perpendicular to a center axis of the plunger body, and measured from the center axis by a second distance.
