METHOD FOR CONSTRUCTING A FIXED-VANE RING FOR A NOZZLE OF A TURBOCHARGER TURBINE

A method for constructing a nozzle ring 40 for a turbocharger turbine nozzle 28 includes the steps of: providing a nozzle ring 42 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 43 extending through the nozzle ring 42 from the first face to the second face; providing a plurality of vanes 44, each vane having a circular vane shaft 46 extending from one end of the vane; inserting the vane shafts 46 respectively into the bores 43 in the nozzle ring from said first face thereof and orienting each vane 44 to achieve a desired setting angle for the vane; and rigidly affixing the vane shafts 46 to the nozzle ring 42 to fix the vanes at the desired setting angles.
