Abstract:
A machine comprising:a rotor rotatably mounted on a rotor shaft to rotate about a rotation axis; an outer rotor housing having a torque-transmitting side and a torque-transmitting side part, wherein the side part is connected to the rotor shaft; a winding comprising a winding former and a superconducting winding, the winding former and the superconducting winding being enclosed by said outer rotor housing; a cooling and thermal insulation unit for the superconducting winding; and a rigid connecting device to hold the winding former within the outer rotor housing on the torque-transmitting side thereof, wherein said rigid connecting device is located between the winding former and the side part of the outer rotor housing, the rigid connecting device comprising: a connecting element that transmits torque, said connecting element being formed of a plastic reinforced with fiber material, the connecting element having a hollow, cylindrical shape, the connecting element comprising: two end-face end parts having a corrugated cross-sectional shape, and a center part located between, and formed integrally with, the end-face end parts, said center part having a cross-sectional shape that is not corrugated; and flange-like end pieces connected in a power-transmitting manner to the winding former or to the side part of the outer rotor housing, wherein the flange-like end pieces are formed of metal, said flange-like end pieces each having groove-like recesses to completely receive the end-face parts of the connecting element and to partially receive the center part of the connecting element, each of said recesses having at least one side wall corrugated to match the cross-sectional shape of the end-face end parts such that when the end face end parts are received in the recesses, there is a communication of corrugation and a space remaining in each recess that is unfilled with the end face part, wherein the connecting element is fixed in place in the recesses by at least partially filling the space remaining.
