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.

Abstract: A generator arrangement includes a stator with armature winding, a rotor with one or more permanent magnets supported for rotation relative to the stator, a variable speed drive, and a control module. The variable speed drive is connected to the rotor for rotating the rotor within a predetermined speed range. The control module is disposed in communication with the armature windings and is operatively connected to the variable speed drive to maintain constant output voltage as load changes by varying rotational speed of the rotor.

Abstract: Embodiments herein relate to piece-part, sub-assembly, assembly, and component levels of a differential composed of a sun gear configuration and utilized in an integrated drive generator. An integrated drive generator is a hydro-mechanical transmission that drives a synchronous salient pole generator. The integrated drive generator is a constant speed output, variable speed input transmission that includes the differential and a hydraulic unit. In general, the integrated drive generator utilizes the variable speed input from an accessory gear box of an engine to drive or control a hydraulic unit, which in turn drives or controls a churn leg member of the differential. As the differential is driven, speeds of each speed member of the differential are then summed to generate the constant speed output to drive the synchronous salient pole generator.
