    Abstract: A retaining ring configured to retain a shaft to a sleeve to fix the shaft rotationally and axially to the sleeve can include a first portion configured to install around the shaft and within the sleeve. The first portion can include one or more first curved sections and at least one first portion flat. The retaining ring can include a second portion configured to install around the shaft and moveable relative to the first portion, the second portion comprising one or more second curved sections and at least one second portion flat. The first portion flat can be defined between a plurality of the first curved sections, and wherein the second portion flat can be defined between a plurality of the second curved sections, for example.

    Abstract: A system can include a first generator configured to operate in a first speed range to produce a predetermined output characteristic, a second generator configured to operate at a second speed range different from the first speed range to produce the predetermined output characteristic, and a controller configured to activate the first generator at and/or above a first low activation speed and at and/or below a first high activation speed within the first speed range. The controller can be configured to activate the second generator at and/or above a second low activation speed within the second speed range. The controller can be configured to deactivate the first generator at and/or above a first high deactivation speed. The controller can be configured to deactivate the second generator at and/or below a second low deactivation speed.

    Abstract: A disconnect mechanism includes an input shaft defining a drive axis. A disconnect shaft is selectably engaged with the input shaft to be driven about the drive axis by the input shaft. A disconnect ramp shaft is operatively connected to the disconnect shaft to axially move the disconnect shaft between a first axial position wherein the disconnect shaft is engaged to the input shaft and a second axial position wherein the disconnect shaft is disengaged from the input shaft. The disconnect ramp shaft includes a ramp defined around an outer surface thereof. A disconnect pawl is selectably engaged with the ramp of the disconnect ramp shaft to engage or disengage the disconnect shaft from the input shaft.

    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.
