    摘要： A turbocharger for an internal combustion engine includes a bearing housing and a rotating assembly arranged therein. The rotating assembly includes a shaft with a turbine wheel and a compressor wheel. The turbocharger also includes a thrust bearing assembly operatively connected to the shaft, lubricated by pressurized oil from the engine, and configured to transmit thrust forces developed by the turbine wheel to the bearing housing. The thrust bearing assembly includes a thrust plate having a first thrust face and a thrust washer having a second thrust face. An oil film is generated between the first and second thrust faces, and the first and second thrust faces rotate relative to each other and transmit the thrust forces to the bearing housing. The thrust plate and/or the thrust washer include a circumferential groove configured to trap oil-borne debris and minimize an amount of the debris in the oil film.

    摘要： A turbocharger for an internal combustion engine includes a bearing housing and a bearing bore defined by the bearing housing. The bearing bore has an annular bearing groove configured to receive a fluid. A journal bearing is disposed within the bore such that the annular bearing groove encircles the journal bearing and feeds the fluid thereto. The turbocharger also includes a rotating assembly having a shaft with a turbine wheel and a compressor wheel. The shaft has a longitudinal axis and is supported by the journal bearing for rotation within the bore about the axis. The annular bearing groove is characterized by a trapezoidal shape in a cross-sectional view of the bearing bore taken along and through the longitudinal axis. The trapezoidal shape is configured to generate Taylor vortices in the fluid for capturing debris carried by the fluid and keeping the debris from being fed to the journal bearing.

    摘要： A turbocharger for an internal combustion engine includes a center housing and a bore defined by the center housing. The bore has a primary annular groove and a secondary annular groove configured to receive a fluid. A journal bearing is disposed within the bore proximate to a proximate end of the shaft such that the journal bearing, together with the rotating shaft, feeds fluid to the primary and secondary annular grooves. The shaft is further coupled to a turbine wheel and a compressor wheel. The shaft has a longitudinal axis and is supported by the journal bearing for rotation within the bore about the axis. The primary and secondary annular grooves are each in fluid communication with a drain gallery.

    摘要： 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.

    摘要： An improved thrust bearing for a turbocharger includes a first bearing surface, a second bearing surface, an internal passageway, a primary pad, and a plurality of secondary pads. The internal passageway fluidly connects the first and second bearing surfaces. The primary pad may be defined on the first bearing surface. The primary pad further defines a first aperture in fluid communication with the internal passageway and an oil feed defined in a turbocharger housing. The plurality of secondary pads may also be defined on the first bearing surface. Each secondary pad in the plurality of secondary pads may include a secondary surface area which is smaller than the primary surface area of the primary pad.
