Abstract

La présente invention concerne un outil de meulage de type à bande dans lequel une matière étrangère est empêchée d'entrer à l'intérieur d'un corps d'outil. Une barre de support de poulie (12) est maintenue par un trou de réception de barre (29) dans le corps d'outil (10) de façon à pouvoir coulisser entre une position de transmission de tension dans laquelle la tension est appliquée à une bande abrasive sans fin (20) et une position de libération de tension dans laquelle le levier de support de poulie (12) est rétracté de la position de transmission de tension et la tension sur la bande abrasive sans fin est libérée. Un trou de réception d'élément de verrouillage (33), qui présente une section transversale circulaire et qui est sensiblement orthogonal au trou de réception de barre (29), est formé dans le corps d'outil (10), et un élément de verrouillage sensiblement cylindrique (34) est positionné de manière coulissante dans le trou de réception d'élément de verrouillage (33). L'élément de verrouillage (34) peut être déplacé entre une position de verrouillage dans laquelle la barre de support de poulie (12) est verrouillée de façon à être maintenue dans la position de libération de tension, et une position de déverrouillage dans laquelle la barre de support de poulie (12) est déverrouillée et peut être déplacée entre la position de transmission de tension et la position de libération de tension. Un élément de joint d'étanchéité annulaire (38) est positionné entre la surface périphérique externe (34a) de l'élément de verrouillage (34) et la surface périphérique interne (33c) du trou de réception d'élément de verrouillage (33).
