Abstract

Una conexión roscada de una construcción de rosca de dos pasos que incluye superficies de hombro intermedio, en donde se evita una rotura cerca de las secciones transversales críticas intermedias con la aplicación de una carga de tracción y resultando mejores de crear las superficies de hombro intermedio, mejorando así la productividad. La porción de periferia exterior del vástago 2 ubicada entre la superficie de hombro intermedio 24 del vástago 2 y la segunda rosca macho 27 se provee con un surco circunferencial 25 que incluye una superficie curvada 25a suavemente contigua a la superficie de hombro intermedio 24, mitigando por lo tanto las deformaciones plásticas generadas cerca de la sección transversal crítica intermedia de vástago STCIV. La porción periférica interior de la caja 3 ubicada entre la superficie de hombro intermedio 35 de la caja 3 y la primera rosca hembra 32 se provee con un surco circunferencial 34 que incluye una superficie curvada 34a suavemente contigua a la superficie de hombro intermedio 35, mitigando por lo tanto las deformaciones plásticas generadas cerca de la sección transversal crítica intermedia de caja STCIC.
