In a hydroelectric generating set with a rotor wheel (2), the rotor blade ends (3) of which engage in an outer ring (5), which carries the rotor of an electric generator, reliable centring of the rotor wheel hub (4) and outer ring (5) is achieved in that in the rotor wheel hub (4) a displacement device (7) is provided, by means of which rods (6) extending through the rotor blades or the rotor blades (3) themselves are displaceable by equal amounts in a radial direction. The displacement device may comprise, for example, an axially displaceable cone (15) with radially displaceable shoes (16) resting on this or an axially displaceable ring (10) with a number of angle levers (11). <IMAGE>
