Patent ID: 7075208

Claim:
A machine having a rotor mounted on a rotor shaft to rotate about a rotation axis, comprising: a rotor external housing which is attached to the rotor shaft; a winding comprising a winding former and a winding that is to be cooled, the external housing surrounding the winding former and the winding that is to be cooled; a device which transmits torque between the winding former and the rotor shaft, the device being provided for at least one end of the winding former, the device comprising: a pair of metal flange attachment parts, each having a mating surface; and a rotationally symmetrical composite body composed of a plastic reinforced with fiber material, to connect the metal flanges, wherein the composite body comprises side parts and a center part integrally located between the side part, the side parts each having a funnel portion that widens away from the winding former, the center part being formed as a hollow cylinder, at least a portion of the center part extending freely between the attachment parts, wherein the side parts each have a corrugated portion with a corrugated shape when seen in the circumferential direction, the center part is largely uncorrugated, the side parts are connected respectively, in an interlocking and power-transmitting manner, to the metal flange attachment parts, and each side part of the composite body is detachably pressed against the mating surface of one attachment part, the mating surfaces of the attachment parts each having a shape that matches that of the respective side part; and a compression ring body detachably connected to each attachment part in a power-transmitting manner, each compression ring body having a pressing surface with a shape matching that of a corresponding side part.
