Abstract: A cam liner for use in an integrated drive generator has a cam liner body extending between a first end spaced from the second end by a first distance. The body is generally cylindrical. An outer diameter of the cam liner defines a second distance. A ratio of the first distance to the second distance is between 0.90 and 1.00. 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 pump sleeve for an integrated drive generator has a pump sleeve body extending between a first end and a second end. The first end is at a location adjacent a radially enlarged end plate. The body extends to the second end with a generally cylindrical body portion having an inner bore diameter defining a first distance. The body extends between the first and second ends for a second distance. A ratio of the first distance to the second distance is between 0.15 and 0.30. 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.

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.
