VARIABLE PIVOT CENTER VTG VANES AND VANE PACK ASSEMBLY

摘要

A vane pack assembly (14) for a variable turbine geometry turbocharger is a stand-alone assembly and can be assembled and transported apart from the turbocharger. The vane pack assembly (14) includes a plurality of guide vanes (16) spaced apart in a circumferential direction and a plurality of pivot centers (38). Each one of the pivot centers (38) corresponds with one of the guide vanes (16). A location of the pivot centers (38) relative to the guide vanes (16) changes as an angular position of the guide vanes (16) is adjusted.
