Claim 1

IN AN ELECTRICAL MOTOR, THE COMBINATION FOR A HOLLOW HOUSING STRUCTURE HAVING A CYLINDRICAL SIDE WALL, ANNULAR END WALLS, AND A TUBULAR PORTION SPACED INWARDLY FROM SAID SIDE WALL AND PROJECTING FROM ONE OF SAID END WALLS TOWARD THE OTHER OF SAID END WALLS BUT TERMINATING SHORT OF SAID OTHER END WALL; A STATOR CARRIED BY SAID HOUSING STRUCTURE; A SHAFT EXTENDING THROUGH SAID HOUSING STRUCTURE, SAID SHAFT INCLUDING A PORTION DISPOSED WITHIN SAID TUBULAR PORTION OF SAID HOUSING STRUCTURE, SAID SHAFT ALSO INCLUDING ANOTHER PORTION PROJECTING OUTWARDLY OF SAID HOUSING THROUGH SAID ONE END WALL; BEARING MEANS MOUNTED BETWEEN SAID SHAFT AND SAID END WALLS FOR ROTATABLY SUPPORTING SAID SHAFT ON SAID HOUSING; A HOLLOW ROTOR STRUCTURE OPERATIVELY ARRANGED RELATIVE TO SAID STATOR, SAID SHAFT EXTENDING THROUGH SAID ROTOR STRUCTURE, SAID ROTOR STRUCTURE BEING DISPOSED BETWEEN SAID OTHER END WALL AND THE ADJACENT END OF SAID TUBULAR PORTION AND SAID HOUSING STRUCTURE, SAID ROTOR STRUCTURE COMPRISING A HOLLOW MEMBER CONCENTRIC WITH SAID SHAFT AND PROJECTING INTO SAID TUBULAR PORTION OF SAID HOUSING STRUCTURE; MEANS SUPPORTING SAID ROTOR FOR ROTATION ABOUT SAID SHAFT; AND SPEED REDUCTION MEANS OPERATIVELY ASSOCIATED WITH THE OTHER END OF SAID ROTOR STRUCTURE TO PROVIDE A DRIVING CONNECTION BETWEEN SAID ROTOR STRUCTURE AND SAID SHAFT, SAID SPEED REDUCTION MEANS COMPRISING A DEFORMABLE ANNULAR ELEMENT SURROUNDING SAID HOLLOW MEMBER AND PROVIDED WITH A CLOSED SERIES OF OUTWARDLY FACING GEAR TEETH, A CLOSED SERIES OF INWARDLY FACING GEAR TEETH CARRIED BY SAID TUBULAR PORTION OF SAID HOUSING STRUCTURE AND SURROUNDING SAID DEFORMABLE ELECMENT, A PLURALITY OF ANTI-FRICTION BEARING ELEMENTS DISPOSED BETWEEN SAID HOLLOW MEMBER AND SAID DEFORMABLE ELEMENT, THE OUTER SURFACE OF SAID HOLLOW MEMBER BEING OF SUCH SHAPE AS TO CAUSE SAID BEARING ELEMENTS TO DEFLECT SAID DEFORMABLE ELEMENT RADIALLY OUTWARDLY AT AT LEAST TWO CIRCUMFERENTIALLY SPACED POINTS TO BRING THE GEAR TEETH OF SAID DEFORMABLE ELEMENT AT SUCH POINTS INTO MESH WITH THE TEETH CARRIED BY SAID TUBULAR PORTION OF SAID HOUSING, THE GEAR TEETH OF SAID DEFORMABLE ELEMENT BEING OUT OF ENGAGEMENT WITH THE GEAR TEETH OF SAID TUBULAR PORTION IN AREAS BETWEEN SAID SPACED POINTS, AND A TUBULAR DEFORMABLE STRUCTURE SURROUNDING SAID SHAFT WITHIN SAID TUBULAR PORTION OF SAID HOUSING AND HAVING ONE END FIXED TO SAID DEFORMABLE ELEMENT AND THE OTHER END FIXED TO SAID SHAFT, SAID TUBULAR DEFORMABLE STRUCTURE BEING OPERATIVE TO IMPART ROTARY MOVEMENT OF SAID DEFORMABLE ANNULAR ELEMENT TO SAID SHAFT.
