VERBINDUNG EINES KERAMISCHEN TURBINENRADES MIT EINER METALLISCHEN WELLE

摘要

The mounting for a ceramic rotor (1) esp. a turbine wheel on a metallic shaft (2) comprises a frictional connection, formed by making the rotor a shrink fit on the shaft. Alternatively the shaft and the rotor may be pressed together axially by a screw through both. The rotor could instead be welded or soldered to the shaft. Welding is esp. by friction welding at the end faces of the two components. Diffusion welding may be used at other conical surfaces. The shaft may be a molybdenum-titanium alloy.
