Abstract: A turbocharger including 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. The rotary assembly being subject to aero-load in a lateral direction. A bearing is disposed in the housing and rotatably supports the shaft, the bearing including an inner bearing surface that engages the shaft and an outer bearing surface that engages the housing, the outer bearing surface having a pair of axially extending recessed grooves extending at least partially along the bearing. The pair of axially extending grooves being located perpendicular to the aero-load direction

Abstract: 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.

Abstract: A turbine wheel and shaft assembly is provided for a turbocharger including a turbine wheel including a body portion supporting a plurality of blades on a first axial face thereof. A hub extends from a body portion on a second axial face. A shaft is welded to the hub at a weld location spaced from the second axial face. The weld location is spaced axially from the second axial face by a distance sufficient to provide a significant reduction in the residual stresses in the welded parts. This design is intended to mitigate turbine wheel imbalance problems.

Abstract: A turbocharger for an internal combustion engine includes a center housing which defines a bore, a recess, and an annular groove. The annular groove and the recess may be configured to receive a fluid. A bearing is disposed within the bore proximate to the a turbine wheel such that the bearing, together with the rotating shaft, feeds fluid to the annular groove and recess. The shaft may be further coupled to the turbine wheel at a proximate end and a compressor wheel at a distal end. The shaft has a longitudinal axis and is supported by the bearing for rotation within the bore about the axis. The annular groove is in fluid communication with a drain gallery via a conduit.

Abstract: 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.
