Abstract
A rotating machine has a splined primary shaft rotatably mounted in an opening of an oil-filled housing and a primary seal carried by the housing for sealingly engaging with a mating splined secondary shaft upon insertion of the secondary shaft into the housing opening for engagement with the splined primary shaft. An annular seal is also carried by the housing and has a flexible sealing lip for sealing engagement with the primary shaft to maintain oil within the housing. The annular seal has an abutment lever which extends toward the opening to be engaged by the splined secondary shaft upon insertion of the secondary shaft through the housing opening to forcibly pivot the flexible sealing lip of the annular seal away from sealing engagement with the primary shaft and thereby permit oil to flow to lubricate the splines between the primary and secondary shafts.
