Title (EN) TOOL FOR PRODUCING CROWN WHEELS, AND METHOD FOR PRODUCING SUCH A TOOL
(FR) OUTIL POUR LA PRODUCTION DE COURONNES DENTEES ET PROCEDE DE PRODUCTION DUDIT OUTIL
Abstract:
(EN) A tool for producing crown wheels by means of a generating process comprises a disc which is rotatable about its axis, with machining elements which are provided on the periphery thereof and the cutting edges of which lie in the outer surface of a profile determining the shape of the teeth of a crown wheel to be produced with the tool, said profile extending essentially helically over the periphery of the disc. In each cross-section of the helical profile the outer contour (25) of the cross-section is at least composed of a part of the outer contour of the tooth profile of an imaginary gear wheel (23) with involute teeth and preferably straight lines connecting thereto, in such a way that in the case of each of the teeth (22) with a tooth tip and two tooth flanks bounded by the outer contour (25) of the cross-section the distance between each of the two tooth flanks and a line at right angles to the axis of rotation of the tool and passing through the tooth tip remains the same or increases from the tooth tip to the axis of rotation of the tool.
(FR) Outil destiné à la production de couronnes dentées à l'aide d'un procédé de taillage en développante. L'outil comporte un disque apte à tourner autour de son axe et portant au niveau de sa périphérie des éléments d'usinage dont les bords coupants se trouvent dans la surface externe d'un profil déterminant la forme des dents d'une couronne dentée devant être fabriquée par ledit outil, ledit profil s'étendant de manière essentiellement hélicoïdale à la périphérie dudit disque. Le pourtour extérieur (25) de chaque section transversale du profil hélicoïdal est au moins constitué d'une partie du pourtour extérieur du profil des dents d'une roue dentée imaginaire (23) à denture développante à laquelle sont reliées des lignes de préférence droites. Ainsi, dans le cas où chaque dent (22) possède une pointe et deux flancs limités par le pourtour extérieur (25) de la section transversale, la distance séparant chacun des deux flancs d'une ligne qui est normale à l'axe de rotation de l'outil, et qui traverse la pointe de la dent, demeure inchangée ou s'accroît à partir de la pointe et en direction de l'axe de rotation de l'outil.
