Abstract

LA PRESENTE INVENTION CONCERNE UN MECANISME D'ENTRAINEMENT A MOUVEMENT PERDU. SELON L'INVENTION, IL COMPORTE UN MOTEUR 30, UN ARBRE D'ENTREE ROTATIF AUTOUR D'UN PREMIER AXE, UN ORGANE D'EMBRAYAGE 38, 40 RELIANT SELECTIVEMENT L'ARBRE D'ENTREE AU MOTEUR, UN ARBRE DE SORTIE 50 ROTATIF AUTOUR D'UN SECOND AXE RADIALEMENT DECALE DU PREMIER, UN PREMIER MOYEN 46 DE MISE EN ACTION RELIE A L'ARBRE D'ENTREE, UN SECOND MOYEN DE MISE EN ACTION 48 RELIE A L'ARBRE DE SORTIE, L'UN DE CES MOYENS COMPORTANT UNE BROCHE 86 RADIALEMENT DECALEE DE SON AXE DE ROTATION, AXIALE PAR RAPPORT A LUI, L'AUTRE COMPRENANT UN ORGANE DEFINISSANT UNE GORGE RADIALE RECEVANT COULISSANTE LA BROCHE, UN MOYEN D'ACCOUPLEMENT 44 CHARGE PAR RESSORT MONTE SUR L'ARBRE D'ENTREE POUR PROVOQUER L'EMBRAYAGE ET RELIER CET ARBRE AU MOTEUR QUAND IL EST LIBERE, ET UN SOLENOIDE 52 RELIE AU MOYEN D'ACCOUPLEMENT POUR LE LIBERER QUAND IL EST EXCITE. L'INVENTION S'APPLIQUE NOTAMMENT AU TRANSPORT RAPIDE DE PELLICULE A RAYONS X.THE PRESENT INVENTION RELATES TO A LOST MOTION DRIVE MECHANISM. ACCORDING TO THE INVENTION, IT INCLUDES A MOTOR 30, A ROTATING INPUT SHAFT AROUND A FIRST AXLE, A CLUTCH 38, 40 SELECTIVELY CONNECTING THE INPUT SHAFT TO THE MOTOR, A ROTATING OUTPUT SHAFT 50 AROUND OF A SECOND AXIS RADIALLY OFFSET FROM THE FIRST, A FIRST MEANS 46 OF ACTION CONNECTED TO THE INPUT SHAFT, A SECOND Means of ACTION 48 CONNECTED TO THE OUTPUT SHAFT, ONE OF THESE MEANS INCLUDING A SPINDLE 86 RADIALLY OFFSET FROM ITS ROTATION AXIS, AXIAL WITH RESPECT TO IT, THE OTHER INCLUDING A BODY DEFINING A RADIAL THROAT SLIDING RECEIVING THE SPINDLE, A COUPLING MEANS 44 LOADED BY SPRING MOUNTED ON THE INPUT SHAFT FOR DRIVE THE CLUTCH AND CONNECT THIS SHAFT TO THE MOTOR WHEN IT IS RELEASED, AND A 52 SOLENOID CONNECTS TO THE COUPLING MEDIA TO RELEASE IT WHEN IT IS ENERGIZED. THE INVENTION APPLIES IN PARTICULAR TO THE RAPID TRANSPORT OF X-RAY FILM.
