Abstract
Un aléseur (10) à rouleaux rotatifs, destinés à un puits de forage, comprend plusieurs rouleaux (11) dont chacun tourne autour d'un axe (13) fixe maintenu à ses extrémités dans des cales en biseau. L'axe (13) comporte deux passages (19) centraux, un à chaque extrémité. A une extrémité, le passage (19) contient un piston (21) coulissant soumis à la pression extérieure par la présence d'une prise d'air (22). Le passage (19) de l'autre extrémité est fermé par un bouchon (27) de pression qui, une fois retiré, permet l'injection de graisse dans les passages qui incluent les surfaces de paliers du rouleau (11) et de l'axe (13). La pression extérieure est appliquée à cette graisse par le piston (21), de façon qu'il n'existe que peu ou pas de différence de pression qui chasse la boue dans les paliers.
