A saw axle for floatingly supporting a plurality of saw blades which are dogged by the rotational movement of the axle as a result of form-locking between the outer contour of the axle (4) and corresponding holes in respective blades. The outer contour of the axle (4) and the contour of the blade-mounting hole each have three main sides for achieving statically determined three-point contact between axle and blade. The axle preferably comprises a core axle (1) and a sleeve (4) non-rotatably mounted thereon, wherein the outer contour of the sleeve presents the aforesaid three main surfaces. The invention also relates to a saw blade which can be fitted onto the axle.
La présente invention concerne un axe de scie destiné au montage flottant d'un certain nombre de lames de scie, ces dernières étant entraînées par la rotation de l'axe en raison du verrouillage par coïcidence des formes entre la forme extérieure (4) de l'axe et un trou correspondant dans la lame considérée. La forme extérieure (4) de l'axe et la forme du trou de la lame présentent trois côtés principaux pour obtenir un contact à trois points, déterminé statiquement, entre l'axe et la lame. De préférence, l'axe est constitué par un noyau (1) et un manchon (4) monté sur lui d'une manière empêchant toute rotation, et la forme extérieure du manchon présente les trois surfaces principales. L'invention concerne également une lame de scie destinée à être montée sur l'axe en question.
