Abstract

L'INVENTION CONCERNE UN MANDRIN POUVANT ETRE MANOEUVRE SANS CLE. CE MANDRIN COMPORTE UNE EMBASE 22 FIXEE A UN ARBRE DE MACHINE-OUTIL, PAR EXEMPLE UNE PERCEUSE PORTATIVE, ET UNE BAGUE 20 MONTEE SUR CETTE EMBASE AU MOYEN DE FILETS 24 ET 26, DE MANIERE A POUVOIR SE DEPLACER AXIALEMENT PAR RAPPORT A L'EMBASE 22. DES MORS 44 SONT MONTES A L'INTERIEUR D'UN CONE 50, LUI-MEME LOGE DANS LA BAGUE 20, ET CES MORS PORTENT CONTRE L'EXTREMITE DE L'EMBASE 22 PAR L'INTERMEDIAIRE D'UNE RONDELLE 40 DE BUTEE. CE MONTAGE PERMET DE REALISER LA BAGUE 20 ET L'EMBASE 22 EN MATIERE PLASTIQUE A FAIBLE COEFFICIENT DE FROTTEMENT. DOMAINE D'APPLICATION: PERCEUSES ELECTRIQUES PORTATIVES.THE INVENTION RELATES TO A CHUCK THAT CAN BE OPERATED WITHOUT A KEY. THIS CHUCK INCLUDES A BASE 22 FIXED TO A MACHINE-TOOL SHAFT, FOR EXAMPLE A PORTABLE DRILL, AND A BUSH 20 MOUNTED ON THIS BASE BY MEANS OF THREADS 24 AND 26, SO AS TO BE ABLE TO MOVE AXIALLY WITH RESPECT TO THE BASE 22. OF THE JAWS 44 ARE MOUNTED INSIDE A CONE 50, ITSELF LODGE IN THE RING 20, AND THESE JAWS ARE BEARING AGAINST THE END OF THE BASE 22 THROUGH A WASHER 40 OF THE STOP . THIS ASSEMBLY MAKES THE RING 20 AND THE BASE 22 IN PLASTIC MATERIAL WITH LOW FRICTION COEFFICIENT. FIELD OF APPLICATION: PORTABLE ELECTRIC DRILLS.
