| description | A bearing system configured for use on a downhole tool including a rolling cutter member having a plurality of cutting structures thereon comprises a first plurality of bearings disposed between a head washer and an at least substantially planar shaft washer, and a second plurality of bearings disposed between the at least substantially planar shaft washer and a rolling cutter washer. A downhole tool, such as an earth-boring rotary rolling cutter drill bit includes such a bearing system between a rolling cutter and a head of a bit body. Methods of forming such a downhole tool include the assembly of such a bearing system between a rolling cutter and a head of a bit body.
L'invention concerne un système de paliers conçu pour être utilisé sur un outil de fond de trou, comprenant un élément molette sur lequel se trouve une pluralité de structures de coupe, comprenant une première pluralité de paliers disposés entre une rondelle de tête et une rondelle arbre au moins sensiblement plane et une seconde pluralité de paliers disposés entre la rondelle arbre au moins sensiblement plane et une rondelle de molette. L'invention concerne également un outil de fond de trou, tel qu'un trépan à molettes rotatif de forage terrestre comprenant un tel système de paliers entre une molette et une tête d'un corps de trépan. L'invention concerne également des procédés de formation d'un tel outil de fond de trou, comprenant l'assemblage d'un tel système de paliers entre une molette et une tête d'un corps de trépan. |
