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 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: A disconnect mechanism comprises an input shaft defining a drive axis, a disconnect shaft selectively engaged with the input shaft to be driven about the drive axis by the input shaft, and a disconnect ramp operatively connected to the disconnect shaft to axially move the disconnect shaft between at least a first axial position and a second axial position. A disconnect pawl is selectively engaged with the disconnect ramp shaft, and a brake is selectively engaged with the disconnect shaft in the second axial position.

Abstract: A turbomachine dual spool transmission system can include a transmission assembly configured to connect to a combination output of a dual spool differential at a transmission input to be driven by the combination output to turn a transmission output. The transmission assembly can be configured to provide a first output gear ratio in a first state and a second output gear ratio in a second state. The system can include the dual spool differential. The dual spool differential can include a gear assembly configured to combine a low pressure spool input and a high pressure spool input into a combination output to provide an output speed range smaller than a low pressure speed range alone.
