Abstract
PASADOR ROSCADO QUE TIENE UNA FORMA EXTERNA ROSCADA (13) Y UN VASTAGO (12). EL VASTAGO (12) TIENE AL MENOS UNA RANURA CICUNFERENCIAL (15) CUYA PROFUNDIDAD ES TAL QUE EL AREA DE ESFUERZO EFECTIVO PRODUCIDO ES MENOR QUE EL AREA DE ESFUERZO MINIMO EFECTIVO DEL ROSCADO EXTERNO Y SUPONE TAMBIEN QUE LA DEFORMACION DEL PASADOR ROSCADO TIENE LUGAR AL UTILIZARSE EN LA ZONA DE LAS RANURAS (15) AL TENER LUGAR UNA CARGA PREDETERMINADA. LA PROFUNDIDAD DE LAS RANURAS (15) ES TAL QUE EL DIAMETRO DEL VASTAGO (12) EN LA BASE DE LAS RANURAS SE AJUSTA A LA RELACION: (FIG. A), SIENDO D EL DIAMETRO EN LA BASE DE LAS RANURAS (M), (SIGMA) LA RESISTENCIA A LA TRACCION DEL ALAMBRE (N/M (AL CUADRADO) ), F LA CARGA (N) NECESARIA PARA PRODUCIR LA DEFORMACION DEL PASADOR EN LA ZONA DE LAS RANURAS, Y K UNA CONSTANTE.
