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 block cover for use in an integrated drive generator has a body having a closed outer face and extending to an open inner face, and having an open side and a closed side. There are four connection channels for receiving electric connections for each of three phases of power and a neutral, and they extend from the closed side to the open side. There are spacing channels formed between adjacent ones of each of the four connection channels, with the spacing channels being formed by two spaced ribs with an interior space. An integrated drive generator and a method are also disclosed.

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.

Abstract: A fixed block shaft has a body extending from a first end to a second end. A disc extends radially outwardly of a shaft portion. The shaft portion extends to the second end. The disc extends radially outwardly from the shaft adjacent the first end with a boss extending to the first end from the disc. The boss defines an inner peripheral surface and the inner peripheral surface has a bearing race. The bearing race extends from the first end to a bearing race end. An inner diameter of the bearing race defines a first distance. An inner diameter of the bearing race is defined as a first distance and the bearing race extends along a central axis for a second distance. A ratio of the first distance to the second distance is between 4.30 and 4.50. An integrated drive generator and a method are also disclosed.

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.
