Claim 1
Independent Claim
136 words
A MECHANISM FOR TRANSFORMING A MOVEMENT OF ROTATION INTO A MOVEMENT OF TRANSLATION WHICH COMPRISES A SCREW, A COAXIAL INTERNALLY THREADED SOCKET, THE THREADS OF SAID SCREW AND SOCKET HAVING DIFFERENT INCLINATIONS, THREADED PLANET ROLLERS INTERPOSED BETWEEN SAID SCREW AND SOCKET, THE THREADS OF SAID PLANET ROLLERS HAVING THE SAME INCLINATION AS THE THREADS OF SAID SOCKET, A CAGE COAXIAL TO SAID SCREW AND SOCKET, EACH PLANET ROLLER BEING ROTATABLY MOUNTED ON SAID CAGE, A FIRST SET OF INNER TEETH FORMED IN SAID SOCKET, AND ANOTHER SET OF OUTER TEETH FORMED ON EACH ONE OF SAID PLANET ROLLERS AND IN CONSTANT MESHING ENGAGEMENT WITH SAID FIRST SET OF INNER TEETH OF SAID SOCKET, WHEREBY SAID PLANET ROLLERS CANNOT MOVE AXIALLY RELATIVE TO SAID SOCKET, AND POSITIVE-COUPLING TRANSMISSION MEANS INTERPOSED BETWEEN SAID CAGE AND SAID SOCKET, SO
