Claim 1
Independent Claim
195 words
A DEVICE FOR MOUNTING A FLOATING ROTOR WITHOUT SHAFT OR BEARING IN A ROTATING MACHINE REVOLVING IN UNISON WITH ANOTHER ROTOR FOR TRANSMITTING A TORQUE BETWEEN SAID TWO ROTORS THROUGH A FLUID-TIGHT PARTITION, COMPRISING MAGNETIC COUPLING MEANS FOR TRANSMITTING SAID TORQUE BETWEEN SAID TWO ROTORS, AXIAL THRUST MEANS FOR SAID FLOATING ROTOR, A MAGNETIC CENTERING CIRCUIT COAXIAL AND ADJACENT TO SAID FLOATING ROTOR, SAID MAGNETIC CIRCUIT COMPRISING A POLAR RING CONSISTING OF A PLURALITY OF CONCENTRIC RIBS ENDING WITH SHARP EDGES, MEANS FOR PRODUCING A MAGNETIC FLUX IN SAID MAGNETIC CENTERING CIRCUIT, SAID FLOATING ROTOR COMPRISING AN ANNULUS REGISTERING WITH SAID POLAR RING OF SAID MAGNETIC CENTERING CIRCUIT, SAID ROTOR ANNULUS CONSISTING OF A PLURALITY OF CENCENTRIC RIBS ENDING WITH SHARP EDGES WHICH ARE IDENTICAL WITH THOSE OF SAID POLAR RING OF SAID MAGNETIC CENTERING CIRCUIT, WHEREBY THE REGISTERING SHARP EDGES OF THE ADJACENT RING AND ANNULUS OF SAID MAGNETIC CENTERING CIRCUIT AND SAID FLOATING ROTOR ARE ADAPTED, UPON ENERGIZATION OF SAID MAGNETIC CIRCUIT, TO CONCENTRATE THE MAGNETIC CENTERING FLUX AND THEREFORE TO KEEP SAID FLOATING ROTOR STRICTLY CENTERED ON THE AXIS OF SYMMETRY OF SAID MAGNETIC CENTERING CIRCUIT WHILE DISPENSING WITH ANY MECHANICAL BEARING.
