摘要:
A method for constructing a nozzle ring for a turbocharger turbine nozzle includes the steps of: providing a nozzle ring in the form of an annular flat disk, the nozzle ring having a first face and an opposite second face; forming a plurality of circumferentially spaced circular bores extending through the nozzle ring from the first face to the second face; providing a plurality of vanes, each vane having a circular vane shaft extending from one end of the vane; inserting the vane shafts respectively into the bores in the nozzle ring from said first face thereof and orienting each vane to achieve a desired setting angle for the vane; and rigidly affixing the vane shafts to the nozzle ring to fix the vanes at the desired setting angles.
