Abstract: A supercharger includes a rotor housing defining a pair of cylindrical chambers. A driving shaft bearing is to support a driving rotor shaft for rotation in the rotor housing. A driven shaft bearing is to support a driven rotor shaft for rotation in the rotor housing. An oil sump housing is to enclose a timing gear end of the rotor housing. A shaft seal is disposed between the rotor housing and each respective rotor shaft. The oil sump housing, the rotor housing and driving and driven shaft seals define a closed container for oil to lubricate the driving shaft bearing, the driven shaft bearing, a driving timing gear and a driven timing gear. The oil pools in the closed container and a top surface of the oil is spaced below the timing gears when the driving rotor shaft is in a vertical orientation.

Abstract: A rotating group for a supercharger includes a driving shaft and rotor assembly including a driving shaft connected to a driving rotor. A driven shaft and rotor assembly include a driven shaft connected to a driven rotor. The driving rotor is in intermeshing engagement with the driven rotor to rotate in a pair of transversely overlapping cylindrical chambers defined in a rotor housing of the supercharger. A driving shaft bearing is disposed in a bottom plate to radially and axially support the driving shaft for rotating the driving rotor in the rotor housing at a first predetermined axial location of the driving rotor from the bottom plate. A driven shaft bearing is disposed in the bottom plate to radially and axially support the driven shaft for rotating the driven rotor in the rotor housing at a second predetermined axial location of the driven rotor from the bottom plate.
