Abstract
A variable turbine geometry turbine turbocharger (1) includes vanes (30) configured to control flow of exhaust gas to a turbine wheel (12), and an adjustment ring (40) connected to each vane (30) that controls the angular orientation of all the vanes (30) in unison. The adjustment ring (40) is supported on the bearing housing (16) and is supported on, and piloted relative to, an axially extending nose portion (17) of the bearing housing (16) by surface features (60) formed along an inner edge (43) of the adjustment ring (40).
