Abstract

LA PRESENTE INVENTION CONCERNE UN TREPAN DE FORAGE. L'INVENTION COMPREND UN DISPOSITIF A PALIER DE FRICTION ENTRE UNE FRAISE ET UN ARBRE DE SUPPORT COMPRENANT UNE SURFACE DE POUSSEE ORIENTEE VERS L'INTERIEUR DE L'ARBRE, SOIT LA FRAISE SOIT L'ARBRE COMPRENANT UNE RAINURE D'ASSEMBLAGE L'AUTRE COMPRENANT UNE RAINURE DE RETENTION EN COINCIDENCE, UNE BAGUE A DECLIC DISPOSEE DANS LES RAINURES DE RETENTION, LA RAINURE DE RETENTION AYANT UNE PROFONDEUR INFERIEURE A L'EPAISSEUR DE LA SECTION TRANSVERSALE DE LA BAGUE ET LA RAINURE D'ASSEMBLAGE AYANT UNE PROFONDEUR AU MOINS EGALE A L'EPAISSEUR DE LA SECTION TRANSVERSALE DE LA BAGUE, ET UNE PAROI INCLINEE POUR VENIR EN CONTACT AVEC LA BAGUE ET LA PRESSER DANS LA RAINURE DE RETENTION LORSQUE LE CONE EST POUSSE VERS L'INTERIEUR ET ECARTE DE LA SURFACE DE POUSSEE. L'INVENTION EST UTILISABLE POUR LE FORAGE DE PUITS DE PETROLE.THE PRESENT INVENTION RELATES TO A DRILLING TREPAN. THE INVENTION INCLUDES A FRICTION BEARING DEVICE BETWEEN A CUTTER AND A SUPPORT SHAFT INCLUDING A PUSH SURFACE ORIENTED TOWARDS THE INTERIOR OF THE SHAFT, EITHER THE CUTTER OR THE SHAFT INCLUDING AN ASSEMBLY GROOVE THE OTHER INCLUDING A COINCIDENT RETENTION GROOVE, A CLICK RING PROVIDED IN THE RETENTION GROOVES, THE RETENTION GROOVE HAVING A DEPTH LESS THAN THE THICKNESS OF THE CROSS SECTION OF THE RING AND THE ASSEMBLY GROOVE HAVING A DEPTH AT LEAST THICKNESS OF THE CROSS-SECTION OF THE RING, AND AN INCLINED WALL TO COME IN CONTACT WITH THE RING AND PRESS IT INTO THE RETAINING GROOVE WHEN THE CONE IS PUSHED IN AND AWAY FROM THE PUSHING SURFACE. THE INVENTION CAN BE USED FOR BORING OIL WELLS.
