Abstract
An assembly is provided for mutually coupling a generator rotor which has a superconductive exciter winding, and a shaft, which carries exciter current leads. Disconnectible electrical, hydraulic and mechanical connections are located in the vicinity of the coupling assembly and extend in axial direction of the rotor and the shaft. The coupling assembly includes a pair of coupling halves in the interior of which a hollow chamber, which is gas-tightly sealed against the outer atmosphere, is defined. The disconnectible connections are located in the hollow chamber and include axially movable and releasable telescoping socket-like plug members for a coolant circulatory system and for the exciter current leads. The telescoping socket-like plug members are displaceable in axial direction thereof relative to one another upon insertion thereof in and disconnection thereof from one another and upon thermal expansion thereof. A coaxial channel is formed in the shaft, and a leak suction chamber surrounds the shaft at an end distant from the coupling halves, the coaxial channel connecting the hollow chamber to the leak suction chamber.
