Abstract
Una conexión para utilizarse en perforación por percusión incluye un acoplamiento macho y un acoplamiento hembra. Cada acoplamiento incluye un cuerpo y una rosca de tornillo respectiva, formada sobre una superficie, interna o externa, respectiva, del cuerpo respectivo. Cada rosca tiene una forma de rosca que incluye una cresta, una raíz, un flanco de contacto y un flanco sin contacto. Cada forma de rosca tiene un ángulo de flanco de contacto y un ángulo de flanco sin contacto inclinado en relación a un punto de partida respectivo, ubicado en un diámetro menor o principal, respectivo, del mismo. Cada ángulo de flanco sin contacto es mayor que el ángulo de flanco de contacto respectivo. La cresta de cada forma de rosca se inclina desde el flanco de contacto respectivo hasta el flanco sin contacto respectivo de tal manera que un vértice de la forma de rosca respectiva, que define un diámetro menor o principal, respectivo, de la misma, se ubica adyacente al flanco sin contacto respectivo.
