Title (EN) EARTH-BORING TOOLS INCLUDING ROTATABLE BEARING ELEMENTS AND RELATED METHODS
(FR) OUTILS DE FORAGE COMPRENANT DES ÉLÉMENTS PALIERS ROTATIFS ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) An earth-boring tool for drilling a subterranean formation includes a tool body having a central axis and a cavity extending into the tool body from an outer surface thereof. A bearing element assembly may be mounted within the cavity. The bearing element assembly comprises a lower retaining member, an upper retaining member mounted over to the lower retaining member, the upper retaining member comprising an aperture formed therethrough, and a spherical bearing element disposed over the lower retaining member and extending through the aperture formed through the upper retaining member. The spherical bearing element is rotatable about three axes of rotation within the lower retaining member and the upper retaining member.
(FR) La présente invention concerne un outil de forage pour forer une formation souterraine, ledit outil comprenant un corps d'outil qui a un axe central et une cavité qui s'étend dans le corps d'outil à partir d'une surface extérieure de celui-ci. Un ensemble élément palier peut être monté à l'intérieur de la cavité. L'ensemble élément palier comprend un élément de retenue inférieur, un élément de retenue supérieur monté sur l'élément de retenue inférieur, l'élément de retenue supérieur comprenant une ouverture formée à travers celui-ci, et un élément palier sphérique disposé sur l'élément de retenue inférieur et s'étendant à travers l'ouverture formée à travers l'élément de retenue supérieur. L'élément palier sphérique est rotatif autour de trois axes de rotation à l'intérieur de l'élément de retenue inférieur et de l'élément de retenue supérieur.
