Abstract

An enhanced bearing system for turbochargers incorporates a thrust collar centrally mounted on the rotating shaft interconnecting the turbine and compressor and a thrust bearing centrally located within the center housing to constrain the thrust collar. Central placement of the thrust collar allows journal bearings and journal seals to be placed immediately adjacent the turbine and compressor wheel attachment points on the shaft enhancing the shaft motion characteristics and sealing capability.
