Title
(EN) LAMINATED GEAR SHAVING TOOLS
(FR) OUTILS LAMINES D'EBARBAGE DE ROUES DENTEES
Abstract
(EN) A laminated gear shaving tool is formed by a stack of toothed discs, two of which (60, 61) are shown in developed plan, mounted on a rotatable body. The flanks of each tooth (62a-62h) are cut away to form lands (70, 80), the lands being successively laterally displaced (staggered) across the disc thickness around the circumference, e.g. one cutting edge (76) of the lands (70) moves from the position (70a to 70h). The cutting edges (70, 76, 82, 84) may be inclined across the tooth thickness and/or the lateral faces (68, 74, 78, 86) may be re-entrant; the discs (60, 61) may be inclined to the axis of rotation of the tool; and, where the corresponding lands (70, 80) are not staggered, the toothed discs may be separated by spacing discs.
(FR) Un outil laminé destiné à l'ébarbage d'une roue dentée est formé par un empilement de disques, dont deux (60, 61) sont représentés en plan développé, montés sur un corps rotatif. Les flancs de chaque dent (62a-62h) sont crénelés pour former des plats (70, 80), ces plats étant successivement décalés latéralement sur l'épaisseur du disque autour de la circonférence, p.e. une arête de coupe (76) des plats (70) se déplace de la position (70a) à (70h). Les arêtes de coupe (70, 76, 82, 84) peuvent être inclinées sur toute l'épaisseur des dents et/ou les faces latérales (68, 74, 78, 86) peuvent être rentrantes; les disques (60, 61) peuvent être inclinés par rapport à l'acte de rotation de l'outil; là où les plats correspondants (70, 80) ne sont pas décalés, des disques dentés peuvent être séparés par des disques d'espacement.
