Centrifugal air compressor

Abstract

A centrifugal supercharger is disclosed that includes an internal drive mechanism which embodies the present invention. A pair of sprockets are connected to parallel input and output drive shafts and drivingly connected by a taut, high tension, endless cog-belt seated and running on the two sprockets. A plurality of belt stabilizing components are incorporated therein to provide maintenance-free, low-temperature operation of the drive mechanism. These stabilizing components include air ducts formed in the output sprocket, tensioning members formed in the belt, heat-resistant and high-speed ceramic ball bearings and shock absorbing springs that alone and in combination provide a highly efficient drive mechanism.
