摘要： A variable-nozzle turbocharger includes a cartridge containing a variable vane mechanism connected between the center housing and the turbine housing. The cartridge comprises an annular nozzle ring supporting an array of rotatable vanes, an insert having a tubular portion sealingly received into the bore of the turbine housing and having a nozzle portion extending radially out from one end of the tubular portion and being axially spaced from the nozzle ring with the vanes therebetween, a plurality of spacers connected between the nozzle portion of the insert and the nozzle ring, and an annular retainer ring fastened to the center housing so as to capture the nozzle ring between the retainer ring and the center housing. The retainer ring is formed as a separate part from the insert ring and is mechanically and thermally decoupled from the insert.

摘要： An assembly for a turbocharger can include a locating washer having an axis and a perimeter that includes a chord segment defined by an apothem measured from the axis; a bearing assembly that includes an outer race having an axis and a perimeter that includes a chord segment defined by an apothem measured from the axis; and a housing that includes a bore for receipt of the bearing assembly and a recess for receipt of the locating washer to space apart the axes of the locating washer and the outer race by a distance greater than the sum of the apothems that provides for contact between the chord segments upon rotation of at least one of the locating washer in the recess and the outer race in the bore. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
