Abstract
A gerotor assembly is provided which includes a crankshaft, an inner drive gear, an outer driven gear and a housing defining an oil groove. The inner drive gear defines a plurality of inner gear teeth. The outer driven gear defines a plurality of outer gear teeth operatively configured to engage with the inner gear teeth. The outer drive gear may define a plurality of passageways to form a hydrodynamic film between the outer driven gear and the housing. Alternatively, a high pressure oil pump may feed oil into the oil groove in order to distribute a hydrodynamic film.
