Abstract

PIECE FILETEE A AUTO-BLOCAGE. ELLE PRESENTE UNE FENTE 4 QUI PART RADIALEMENT DE LA CRETE DE SON FILETAGE 2, CELUI-CI AYANT UNE INCLINAISON DE FLANC PLUS FAIBLE QUE LE FILETAGE 7 DE LA PIECE FILETEE COOPERANTE 6, DE SORTE QU'IL SE DEFORME ELASTIQUEMENT EN S'ENGAGEANT DANS LE FILETAGE 7, DANS LE SENS DE REDUCTION DE LA LARGEUR DE LA FENTE 4, ET QUE SES FLANCS 2 S'APPLIQUENT FORTEMENT CONTRE LES FLANCS DU FILETAGE 7, LE FROTTEMENT ENTRE FLANCS OPPOSES RESISTANT AU DESSERRAGE. APPLICATIONS : BOULONS ET ECROUS, CONNECTEURS ELECTRIQUES, ETC.SELF-LOCKING THREADED PART. IT HAS A SLOT 4 WHICH STARTS RADIALLY FROM THE CREST OF ITS THREAD 2, THE latter HAVING A LOWER SIDE TILT THAN THE THREAD 7 OF THE COOPERATING THREADED PART 6, SO THAT IT IS ELASTICALLY DEFORMED BY ENGAGING IN THE THREAD 7, IN THE DIRECTION OF REDUCING THE WIDTH OF THE SLOT 4, AND THAT ITS SIDES 2 APPLY STRONGLY AGAINST THE SIDES OF THE THREAD 7, THE FRICTION BETWEEN OPPOSED SIDES RESISTANT TO LOOSENING. APPLICATIONS: BOLTS AND NUTS, ELECTRICAL CONNECTORS, ETC.
