Abstract

Turbine apparatus for a hydroelectric power station, with a turbine impeller, which is capable of rotating about a turbine rotary spindle, which is in particular arranged vertically, with turbine blades (4), which are fitted at an angle with respect to the turbine impeller (3), in particular a fixed angle, with a generator, which converts the mechanical rotation energy of the turbine impeller into electrical energy, wherein the generator is in particular an annular generator (5), with an annular rotor (6) and a stator (7), which is correspondingly arranged in annular fashion, wherein the turbine rotary spindle (2) is coupled to the rotor (6) in such a way that it is fixed against rotation, and the rotation about the turbine rotary spindle (2) takes place by means of a hollow shaft (8), with a pot-like receptacle (9), into which a fixed bearing journal (10) with movable bearings (11) arranged around it is inserted, in particular directly, and the turbine impeller (3) and the rotor (6) are capable of rotating about the bearing journal (10).
