Abstract

LA TUERCA AUTOBLOQUEABLE, INTERNAMENTE ROSCADA TIENE UNA SECCION DE BLOQUEO DE FORMA TRIANGULAR (24) QUE TIENE UNAS ZONAS SOBRESALIENTES CIRCUNFERENCIALMENTE SEPARADAS (40). LAS ZONAS SOBRESALIENTES (40) FORMAN UNA SUPERFICIE ADAPTADA PARA SER ENCAJADA POR UN ATORNILLADOR TRIANGULAR QUE APRIETA LA TUERCA SOBRE UN TORNILLO HASTA UNA CARGA AXIAL PREDETERMINADA. CUANDO SE ALCANZA LA CARGA PREDETERMINADA LAS PARTES SOBRESALIENTES (40) SON PLASTICAMENTE DEFORMADA HACIA EL INTERIOR SOBRE LA TUERCA DE MANERA QUE EL ATORNILLADOR GIRE LIBREMENTE SOBRE LA TUERCA. CUANDO LAS PARTES SOBRESALIENTES (40) ESTAN DEFORMADAS HACIA EL INTERIOR, EL MATERIAL DEFORMADO INCIDE SOBRE EL TORNILLO, BLOQUEANDO DE ESTA FORMA ROTACIONALMENTE LA TUERCA SOBRE EL TORNILLO.
