TURBOCHARGER WITH THRUST BEARING PROVIDING COMBINED JOURNAL AND THRUST BEARING FUNCTIONS

摘要

Turbochargers typically include separate hydrodynamic journals and thrust bearings. To form a turbocharger with a reduced axial space envelope, a turbocharger thrust bearing for a turbocharger is provided for integrating the function of the journal bearing into the thrust bearing while maintaining the thrust bearing function. Such a thrust bearing includes a bore shaped to have a plurality of tapered-land pairs circumferentially distributed around the bore. As a result, the axial length of the turbocharger bearing housing and shaft can be reduced.
