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.

Abstract: A port plate assembly of a hydraulic unit includes a port plate and a journal bearing. The port plate includes a fixed-speed interface side having a fixed-speed interface surface, and a variable-speed interface side having a variable-speed interface surface. A plurality of kidney-shaped apertures is defined at a kidney pitch diameter about a central bore of the port plate between the fixed-speed interface surface and the variable-speed interface surface. The port plate also includes control cylinder interface formed at a control cylinder radial offset from a central axis of the central bore, where a ratio of the control cylinder radial offset to the kidney pitch diameter is between 1.629 and 1.639. The journal bearing is installed in the central bore of the port plate, where the journal bearing provides an interface for a fixed-speed shaft and a variable-speed shaft of the hydraulic unit.
