Abstract: A disconnect shaft of an integrated drive generator is provided including a body configured to rotate about an axis of rotation. The body has a first end, a second opposite end, and a plurality of teeth formed adjacent the first end and configured to engage a complementary portion of an adjacent component. A relief is formed in the body such that a first portion is defined between the relief and the plurality of teeth. The first portion includes a plurality of threads having at least one of a major diameter between about 1.3044 and about 1.3125 inches (3.313-3.334 centimeters), a minor diameter between about 1.2482 and about 1.2547 inches (3.170-3.187 centimeters), a pitch diameter between about 1.2765 and about 1.2800 inches (3.242-3.251 centimeters), and a root radius between about 0.0075 and 0.0090 inches (0.0190-0.0029 centimeters).

Abstract: An assembly comprises a resistor plate for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine, and the resistor plate defines a main annular body around the shaft bore. A first protrusion extends radially outward from the main annular body, so that a first pin bore extends through the first protrusion. At least one contact band is seated in a the pin bore of the resistor plate for mounting a direct current (DC) pin to the resistor plate.

Abstract: A resistor pack assembly including an anti-rotation housing. The anti-rotation housing includes a first surface, a second surface opposite the first surface, one or more anti-rotation lugs extending away from the first surface, and an internal cavity extending from the second surface into the anti-rotation housing towards the first surface. The resistor pack assembly also including a positive rail located at least partially within the internal cavity, a negative rail having an inner circular face and an outer circular face located radially outward from the inner circular face, and an insulator ring is interposed between the second surface of the anti-rotation housing and the outer circular face of the negative rail.

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 pump sleeve for an inversion pump in an integrated drive generator has a pump sleeve body extending between a first end and a second end, the first end being at a location adjacent an enlarged endplate. The body extends to the second end with a generally cylindrical body portion having a bore of an inner diameter from the first end to the second end, and between the first and second ends for a distance. A ratio of the first distance to the inner diameter being is 1.8 and 2.0. In addition, an integrated drive generator is disclosed as is a method of replacing an accessory drive gear in an integrated drive generator.

Abstract: A lamination for use in an integrated drive generator is formed from a plurality of plates having a body including a pair of opposed cylindrical surfaces. Non-cylindrical ditches are defined circumferentially intermediate the pair of cylindrical surfaces. A plurality of passages are formed in an outer periphery of the cylindrical surfaces including relatively large holes extending through a slot to the outer periphery. Grooves are formed intermediate the relatively large holes.

Abstract: A variable wobbler plate has a stub shaft and a pivot shaft. The pivot shaft has a smaller diameter portion and a larger diameter portion. The smaller diameter portion has a generally cylindrical outer periphery with a flat over a limited circumferential extent and a diameter to opposed portions of the generally cylindrical portion defining a first distance. A second distance is defined from an end of the smaller diameter portion spaced furthest from the stub shaft to an end of the larger diameter portion spaced closest to the stub shaft and measured along a central axis of the pivot shaft and defines a second distance. A ratio of the first distance to the second distance is between 0.60 and 0.75. An integrated drive generator and a method are also disclosed.
