Abstract
An improved compound planetary gear system. In embodiments, a compound planetary gear system includes a flexure. A seal is disposed within a portion of the flexure of the ring gear, to create a dam for oil to accumulate behind the ring gear, thermally coupling the ring gear to the casing of the compound planetary gear system, which may increase the thermal conductivity between the ring gear and the casing. In this manner, the heat transfer provided by the flexure ring gear may be improved, which may address problems with limited heat transfer (e.g., during a loss of lubrication event) present in typical systems due to the flexure.
