Abstract

SE DESCRIBE UN SUJETADOR ROSCADO, DONDE SE DEFINE, DURANTE SU ENROSCADO CON UNA PIEZA, UNA COMBINACION DE PARES DE FUERZAS Y UN MOMENTO RESULTANTE DE LOS PARES DE FUERZA QUE ORIGINAN EL FLUJO DEL MATERIAL DE LA PIEZA ALREDEDOR DEL TORNILLO, PARA DARLE FUERZAS DE CONTACTO ENTRE LAS ROSCAS DEL TORNILLO Y LAS DE LA PIEZA DE TRABAJO. EL TORNILLO ENROSCADO CONSTA DE UNA PARTE ENROSCADA (11) QUE DEFINE UN EJE (A) Y UNA PARTE DE CABEZA CONDUCTORA (10) Y UN PERFIL DE ROSCA (15) QUE EN SECCION TRANSVERSAL AL EJE TIENE UN NUMERO DE ZONAS QUE INCLUYEN UNA PRIMERA ZONA QUE CONSTA DE UNA CARA ENROSCADA (29) QUE DEFINE UN PRIMER ANGULO CON RELACION A LOS EJES DEL CUERPO Y UNA SEGUNDA ZONA QUE CONSTA DE UNA CARA DE ROSCA EN FORMA DE HUSO (31) QUE DEFINE UN RADIO DE CURVATURA PREDEFINIDO, DE TAL MANERA QUE EL MATERIAL DE LA PIEZA ES INDUCIDO A FLUIR, DURANTE EL ENROSCADO, GENERALMENTE EN DIRECCION RADIAL HACIA DENTRO Y FUERA CON RESPECTO A LA DIRECCION DE AVANCE DEL TORNILLO CON RELACION A LA PIEZA, HACIALA CARA ANGULADA (29), CON OBJETO DE INCREMENTAR LA SUPERFICIE DE CONTACTO Y CONSEGUIR UNA MAYOR FRICCION ENTRE LAS PARTES EN CONTACTO DE LA PIEZA Y LA CARA DEL TORNILLO (29) Y REDUCIR LA TENDENCIA DE ESTE Y LA PIEZA A SOLTARSE BAJO FUERZAS APLICADAS EXTERNAMENTE, Y SUMINISTRAR UNA RELACION DE FUERZA DE ROSCADO Y REDUCIR LA RESISTENCIA DE CONEXION EN EL MATERIAL DE LA PIEZA.
