Abstract

Une perforatrice de roches fond de trou (une machine de forage de roches située dans le fond du trou) comprend une gaine porteuse (22) montée dans des paliers porteurs mixtes axiaux et radiaux (21,22 et 23,24), la gaine porteuse supportant un tube (30) de guidage sur le côté latéral de la machine avec un élément (31) intercalé dans l'espace intermédiaire. Les paliers (21,22 et 23,24) et la gaine porteuse (22) sont maintenus ensemble de manière axiale entre un épaulement (17) prévu sur le carter (11) de la machine et un manchon (13) de retenue du trépan. Le carter de la machine est soumis en utilisation à de fortes vibrations, mais étant donné que le manchon (13) de retenue du trépan est vissé sur le carter (11) de la machine et transmet la rotation au trépan (14), le système de palier de la gaine porteuse est bien fixé.
