CONTOUR SLEEVE FOR AN EXHAUST-GAS TURBOCHARGER AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to a contour sleeve (11) for an exhaust-gas turbocharger (30) and to a method for producing the same. The contour sleeve (11) is advantageously formed in two parts and comprises a tubular sleeve part (22) and an annular flange (22), said sleeve part and flange being non-detachably connected to one another. As a joining process, use is made in particular of friction welding. The sleeve part (22) itself may be assembled from a plurality of non-detachably connected individual components, for example from a central part (23) and a discharge ring (24).
