Abstract: A rectifier assembly includes a terminal arranged along an assembly axis, a mounting ring axially offset from the terminal and seating a diode, a bus bar received within the mounting ring and electrically connecting the diode to the terminal through the bus bar, and a mounting ring. The mounting ring insulator receives the bus bar, is axially offset from the mounting ring, and contains an insert. The insert fixes the bus bar to the mounting ring insulator and compressively fixing the diode within the mounting ring. Generators and methods of making rectifier assemblies for generators are also described.

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.

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. A ratio of the second distance to the first radius is between 0.25 and 0.40. An integrated drive generator and a method of replacing a disconnect shaft are also disclosed.
