Abstract

Se provee una conexión roscada de alto esfuerzo de torsión con formas de rosca macho y hembra constituidas por roscas en cuña con alta resistencia al cizallamiento y alta resistencia al esfuerzo de torsión. El radio de curvatura r1 de la base del flanco de carga del primer filete de rosca 111, ubicado en el extremo de la forma de rosca macho 11 asociado con la punta, no es menor que la altura de filete de rosca Th × 0.14, y más preferiblemente no menor de Th × 0.16, para mejorar la resistencia al cizallamiento del primer filete de rosca 111. Además, se puede reducir el paso de rosca para incrementar el número de filetes de rosca para incrementar el área de contacto para flancos de carga, o solo el radio de curvatura de la base del flanco de carga del primer filete de rosca ubicado en el extremo de la forma de rosca macho asociado con la punta se puede incrementar y se puede proveer un menor diámetro de curvatura para las otras porciones a fin de incrementar el área de contacto para los flancos de carga, manteniendo por lo tanto una alta resistencia al esfuerzo de torsión.
