Patent number: 9695926Abstract: 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.Type: GrantFiled: April 3, 2015Date of Patent: July 4, 2017Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Glenn C. Lemmers, Jr., Aaron M. Finke, Doren C. Smith, Andrew P. Grosskopf, David S. Behling
