Abstract

Un cabezal de perforación de pozos comprende un alojamiento y un ensamble de rodamientos o cojinetes. El alojamiento tiene una estructura de pared lateral que define un orificio central. El ensamble de cojinetes incluye un barril exterior, un barril interior, unidades de cojinetes y un miembro que ejerce fuerza de presión de precarga. El barril exterior tiene un orificio central y el barril interior se asienta de forma removible dentro del orificio central del alojamiento. Las unidades de cojinete están acopladas entre los barriles para suministrar una alineación concéntrica de los barriles y que permite la rotación entre los dos elementos. Una primera de las unidades de cojinete se configura para llevar cargas ejercidas radialmente entre los barriles y una segunda de las unidades de cojinete se configura para llevar cargas ejercidas longitudinalmente entre los barriles. El miembro que ejerce fuerza de presión de precarga mantiene fuerza sobre la unidad de cojinetes que lleva carga longitudinal y los barriles precargando con ello la fuerza sobre la unidad de cojinetes que lleva carga longitudinal.
