STRUCTURE FOR FIXING THE CURRENT SUPPLY ASSEMBLY IN THE ROTOR OF ELECTRIC MACHINES

A structure for fixing the current-supply assembly in the rotor of an electric machine, such as a turbogenerator and for insuring high reliability of the current supply assembly. The device insures high mechanical strength of the supply assembly as well as satisfactory electric contact. The current-supply assembly comprises a rotor shaft whose central hole accommodates current-conducting bars; a bushing fitted on the rotor shaft and sliprings fitted on the bushing and electrically insulated therefrom; current-conducting screws making electrical connection between buses coupled to the sliprings and the current-conducting bars, said current-conducting screws and buses being also insulated from the rotor shaft and the bushing to which they are fixed with the help of keys disposed in the axial and transverse slots provided in the bushing.
