Abstract

Dispositif auxiliaire pour train de tiges de forage ou autre raccord ayant un corps pourvu d'un alésage et doté d'une pluralité de moyens de roulement sur une partie extérieure du corps. Chaque moyen de roulement comporte un ou plusieurs rouleaux et peut tourner par rapport au corps autour d'un axe transversal à un axe de l'alésage. L'agencement est tel que le rouleau peut tourner par rapport au corps pour faciliter la réduction de frottement rotationnel et axial.
