Abstract
Official abstract text for this publication.
A turbocharger is provided including a housing with a turbine and a compressor disposed in the housing. A central shaft is connected between the turbine and the compressor and is rotatably supported by a first journal bearing disposed within the housing at a location adjacent to the turbine and a second journal bearing disposed within the housing at a location adjacent to the compressor. A spacer is disposed directly between and adjacent to the first journal bearing and the second journal bearing and is neither coupled to or integrally formed with the first journal bearing.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbocharger, comprising: a housing; a turbine disposed in the housing; a compressor disposed in the housing; a central shaft connected between the turbine and the compressor; a first journal bearing disposed within the housing and supporting the central shaft at a location adjacent to the turbine and a second journal bearing disposed within the housing and supporting the central shaft at a location adjacent to the compressor; and a spacer disposed directly between and adjacent the first journal bearing and the second journal bearing and coupled for rotation with the first journal bearing, wherein at least one of the spacer and the first journal bearing include protruding engagement feature extending from a side surface thereof and received in a recess formed in a side surface of the other of the at least one of the spacer and the first journal bearing for rotatably engaging the spacer and the first journal bearing together. 2. The turbocharger according to claim 1 , wherein the first and second journal bearings include exterior surfaces with a recessed annular groove. 3. The turbocharger according to claim 2 , wherein the first and second journal bearings include an aperture extending from the recessed annular groove to an interior surface thereof.
