  • Runner with mechanical coupling
    Patent number: 4915589
    Abstract: A runner is provided which consists of a radial turbine ceramic rotor with an integrated ceramic shaft and a non-ceramic compressor impeller which are connected by a releasable, thermally and mechanically loadable mechanical coupling in such a way that the releasable mechanical coupling is located with the compressor impeller. This coupling consists of a cylindrical slotted sleeve which, on the one hand, is fitted into a cylindrical fitting bore in the compressor impeller and, on the other hand, accepts the end of the ceramic shaft in a fitting bore. In addition, the coupling has a tie rod with a screw thread and a pair of conical clamping elements between the cylindrical sleeve and the compressor impeller.
