CARRIER SHAFT FOR A DIFFERENTIAL

摘要

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.

主权项

1. A carrier shaft for an integrated drive generator comprising:
first and second carrier platforms matched machined to control a true position of rolling element races; a first pair of diameter roller bearings on either end of the carrier shaft to support the carrier shaft within the integrated drive generator; and a second pair of diameter roller bearings in a middle of the carrier shaft to support the ring gear to the carrier shaft.
