Abstract: A thermally stressed rotary connection of two coaxially aligned shafts includes two metallic coupling sleeves which are connected with the shafts by way of elastic intermediate layers. The two metallic sleeves engage one another. A ceramic centering sleeve is provided radially around the outside of the coupling sleeves and is shrunk onto the two shafts. The arrangement has the advantage of an effective connectability of different shafts such as ceramic or metal, in which case the two shafts may be connected with one another during the mounting. This allows undivided housings to be used.

Abstract: A guide vane for turbo-engines has a stationary vane section and a movable vane section with a gap between the two sections. The gap is covered on one side by a flexible band connected along its tape edges to the vane sections. The other side of the gap is covered by an elastic connected to the stationary vane section along one band edge while the other band edge overlaps part of the movable vane section to permit free relative movement between the elastic band (7) and the movable vane section. A plurality of such guide vanes are mounted at the radially outer end of their position adjustment member to an outer housing ring while the radially inner vane end or at least the radially inner end of the movable vane is free. A common position adjustment ring is connected to all adjustment members.

Abstract: A rotor blade jacket for an axial gas turbine has a closed ceramic ring surrounding the blade tips of the turbine rotor and surrounded by a protective metal ring holding heat expansion compensating bristles which are secured at their radially outer ends to the protective metal ring and at their radially inner ends to the ceramic ring, whereby the ceramic ring is supported and centered in the turbine housing.

Abstract: A device for the torque-transmissive securing of a disc which is formed of a brittle material, in particular a turbine wheel constituted of a ceramic material, onto a shaft. The disc is centered through the intermediary of two cone pairs with axial prestressing and the torque is transmitted to the shaft through a cylindrical extension of the wheel hub with longitudinal grooves formed on the outer circumference thereof; furthermore transmitted by means of a cylindrical bellshaped cover with symmetrically profiled longitudinal connectors in an inner bore which are conformed to the longitudinal grooves, and finally by rollers located between the concave side edges or slopes and the side walls of the longitudinal grooves in radial and tangential contact therewith, by means of the bell-shaped cover which is rigidly fixed on the shaft.
