Title: Supporting arrangement for the rotor of a vertical electric machine such as hydraulic generator or the like

Abstract: The support arrangement for a vertical electric machine includes a support spider thereof having arms fastened in a concrete wall surrounding the machine. The arms are secured only in the tangential direction. For this purpose, the arms extend into cavities of metal elements set into the concrete wall and are secured therein in the tangential direction by pretensioned rolling members. Because of the rolling motion of the rolling members, radial thermal expansion causes only relatively small radial forces to act and be transmitted to the concrete wall.
