Abstract
Official abstract text for this publication.
A turbocharger includes a housing and a rotary assembly disposed within the housing and including a turbine wheel and a compressor wheel attached to one another by a shaft. A bearing is disposed in the housing and rotatably supports the shaft. The bearing includes a pair of inner bearing surfaces that engage opposite ends of the shaft and a pair of outer bearing surfaces that engage the housing. The pair of inner bearing surfaces have a first axial dimension and the pair of outer bearing surfaces have a second axial dimension that is smaller than the first axial dimension.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbocharger, comprising: a housing; a rotary assembly disposed within the housing and including a turbine wheel and a compressor wheel attached to one another by a shaft; and a one-piece bearing sleeve disposed in the housing and rotatably supporting the shaft, the one-piece bearing sleeve including a pair of inner bearing surfaces that engage opposite ends of the shaft and a pair of outer bearing surfaces that engage the housing, the pair of inner bearing surfaces having a first axial dimension and the pair of outer bearing surfaces having a second axial dimension that is smaller than the first axial dimension, wherein each end of the pair of inner bearing surfaces extend axially beyond each end of the pair of outer bearing surfaces. 2. The turbocharger according to claim 1 , wherein the second axial dimension is smaller than 90% of the first axial dimension. 3. The turbocharger according to claim 1 , wherein the one-piece bearing sleeve is a semi-floating bearing. 4. The turbocharger according to claim 1 , wherein the one-piece bearing sleeve is a fully floating bearing. 5. A bearing, comprising: a one-piece generally cylindrical sleeve including a pair of inner bearing surfaces adapted to engage opposite ends of a shaft and a pair of outer bearing surfaces adapted to engage a bore in a housing, the pair of inner bearing surfaces having a first axial dimension and the pair of outer bearing surfaces having a second axial dimension that is smaller than the first axial dimension, wherein each end of the pair of inner bearing surfaces extend axially beyond each end of the pair of outer bearing surfaces. 6. The bearing according to claim 5 , wherein the second axial dimension is smaller than 90% of the first axial dimension.
