Variable turbine geometry for a charging device and corresponding charging device

摘要

The turbine (1) has guide vanes rotatably supported at a blade bearing ring (2), and a rotatable adjusting ring (5) for rotation of the guide vanes relative to the blade bearing ring. Radial plates (12) adjust and/or fix the adjusting ring in a radial direction and/or adjust a radial clearance (13) of the adjusting ring. The radial plates are eccentrically or asymmetrically formed with respect to a fastening retainer, where the radial plates are attached in the fastening retainer in a rotationally fixed manner and in an installation position.
