Abstract

La présente invention concerne un outil rotatif, qui comprend un adaptateur (20) qui tourne de façon solidaire d’un arbre d’entraînement rotatif, un corps de sac (30) installé sur la face avant de celui-ci, et un corps d’outil rotatif (40) installé sur l’extérieur du corps de sac. Un liquide est enfermé hermétiquement dans le corps de sac (30). Une force centrifuge agit sur le liquide lorsque l’outil rotatif est tourné pour maintenir le corps d’outil rotatif (40) sur le corps de sac (30) à partir de l’intérieur. Un élément de verrouillage (50) destiné à verrouiller le corps d’outil rotatif (40) est installé sur le côté de l’adaptateur (20). Lorsque la vitesse de rotation de l’outil rotatif est réduite, l’élément de verrouillage s’arrête de sorte que le corps d’outil rotatif (40) soit libéré de façon axiale à partir de l’adaptateur (20).
