Abstract

LA INVENCION SE REFIERE A UN ELEMENTO DE FIJACION QUE PORTA UNA ROSCA CON PERFIL ROSCADO EN DISPOSICION OPTIMA DE TENSION PARA CONFIGURACIONES ROSCADAS INTERNAS Y PARTICULARMENTE EXTERIORES, DONDE LA CURVA DE PERFIL ROSCADO SE CARACTERIZA POR UNA MULTIPLICIDAD DE CURVATURAS DIFERENTES QUE SE TRANSFORMAN CON PREFERENCIA DE FORMA CONTINUA, ES DECIR SIN CAMBIO A SALTOS UNA EN OTRA. LAS TANGENTES (15/18) QUE DISCURREN EN LA BASE DE LA ROSCA EN LA CURVA DE PERFIL ROSCADO PRODUCEN PRIMERAMENTE MAS O MENOS LA TENSION PARALELA DE EJE, ALREDEDOR DE LAS CONDICIONES LIGADAS AL EFECTO DE ENTALLADURA. CON UNA DISTANCIA CRECIENTE A LA BASE MAS PROFUNDA DE LA ROSCA AUMENTA EL PASO DEL FLANCO DE ROSCA EN LA CURVATURA DE LA CURVA DE PERFIL ROSCADO, HASTA QUE DESEMBOCA EN UN TRAMO DE FLANCO ROSCADO ALEJADO DE LA BASE ROSCADA. LA CURVA DE PERFIL ROSCADO CON CURVATURAS DIFERENTES PUEDE SER DESCRITA POR MEDIO DE UNO O MULTIPLES SEGMENTOS DE UN CORTE CONICO, ES DECIR DE UNA ELIPSE O DE UNA O MULTIPLES CURVAS DEUNA SEGUNDA DISPOSICION MAS ALTA. EN ARRASTRE DE FORMA Y EN DISPOSICION ROSCADA CON EL MISMO SURCO DE ROSCA SE ENCUENTRAN DE FORMA PREFERENTE CURVADAS TAMBIEN EN EL TRAMO ALEJADO DE LA BASE ROSCADA DEL PERFIL DE ROSCA.
