Abstract
An arrangement for connecting a ceramic rotor wheel, particularly a turbine rotor wheel of a turbomachine, such as a gas turbine, to a metallic shaft. In order to obtain a primarily temperature-resistant (ceramic wheel-to-metal shaft) connection suitable for high speeds, the arrangement includes a thermal insulation ring seated on the shaft journal of a ceramic rotor wheel, on which there is mounted the tubular end portion of the metallic machine shaft, and which is then positioned on the shaft journal for positive connection through the intermediary of at least one fiber ring which is press-fitted onto the end portion of the shaft.
