Abstract

The sprocket or gear-wheel comprises an annular hub (2) to which teeth (1) are secured by tenons (5). The teeth (1) may be of the same size and shape, may be equally distributed around the hub rim, and may have a base profile which complements that of the rim. A tenon (5) may project perpendicularly from the base of each tooth and may enter a radial mortice or socket provided in the hub (2) rim. The hub block may be of moulded plastics and the teeth may be fixed by gluing. Both teeth and block may take diverse forms and the teeth may abut (3) whilst being internally or externally mounted.

Description

La présente invention concerne d'une manière générale tous les dispositifs dentés servant à transmettre un mouvement et plus particulièrement engrenages, pignons à chaîne, roues et disques dentés. The present invention relates generally to all toothed devices used for transmitting movement and more particularly gears, chain sprockets, wheels and toothed discs.

Les objets connus de ce genre de nos jours sont obtenus en taillant dans la masse des évidements ou rainures. La matière restant entre les deux évidements ou rainures constitue la dent. Known objects of this kind nowadays are obtained by cutting in the mass of the recesses or grooves. The material remaining between the two recesses or grooves constitutes the tooth.

Pour obtenir ces pièces, l'utilisation de machines et outils spéciaux sont nécessaires. Une main-d'oeuvre hautement qualifiée est également indispensable pour effectuer les nombreux réglages longs et délicats qui augmentent considérablement le coût de revient. To obtain these parts, the use of special machines and tools is necessary. A highly qualified workforce is also essential to carry out the many long and delicate adjustments which considerably increase the cost price.

Le dispositif suivant l'invention permet d'obvier à ces inconvénients du fait que la fabrication ne demande plus de long usinage et réglage ainsi qutune main-dSoeuvre spécialisée. The device according to the invention overcomes these drawbacks because the manufacturing no longer requires long machining and adjustment as well as specialized labor.

Le gain de temps autorise une production moins coûteuse.The saving of time allows a less expensive production.

En outre, le dispositif est plus léger tout en ayant une grande solidité. In addition, the device is lighter while having great strength.

Le dispositif, objet de l'invention, consiste à rapporter la denture sur un support généralement cylindrique. Les dents sont fabriquées individuellement dans une matière dure puis fixées sur un support par tous moyens appropriés tels que : collage ou manchées en force dans des trous réalisés sur le pourtour dudit support qui tourne. The device, object of the invention, consists in attaching the toothing to a generally cylindrical support. The teeth are produced individually in a hard material and then fixed on a support by any appropriate means such as: gluing or force-fitting in holes made around the periphery of said rotating support.

Le support est fabriqué avec une matière moins dure et plus légère que les dents, tels quten alliages de duraluminium, aluminium, etc... ou moulé avec une matière plastique. The support is made with a material that is less hard and lighter than the teeth, such as alloys of duraluminium, aluminum, etc ... or molded with a plastic material.

Selon des réalisations préférentielles de l'invention, les supports et les dents peuvent avoir des formes variables. According to preferred embodiments of the invention, the supports and the teeth can have variable shapes.

Les dessins annexés illustrent à titre d'exemple non limitatif des modes de réalisation et applications de l'invention.The accompanying drawings illustrate by way of nonlimiting example embodiments and applications of the invention.

La figure 1 représente un montage du dispositif sur le plan vertical, avec denture extérieure. Figure 1 shows an assembly of the device on the vertical plane, with external teeth.

La figure 2 représente un montage partiel du dispositif sur un plan vertical, avec denture intérieure. FIG. 2 represents a partial mounting of the device on a vertical plane, with internal toothing.

La figure 3 représente une vue transversàle des dents dessinées en figure 1 à une plus grande échelle. FIG. 3 represents a transversal view of the teeth drawn in FIG. 1 on a larger scale.

La figure 4 représente une vue latérale des dents dessinées en figure 3. FIG. 4 represents a side view of the teeth drawn in FIG. 3.

Selon les figures 1, 3 et 4, le dispositif comporte des dents 1 positionnées sur le pourtour du support 2 circulaire et sont juxtaposées entre elles par leur base, par le côté 3. According to FIGS. 1, 3 and 4, the device comprises teeth 1 positioned on the periphery of the circular support 2 and are juxtaposed with one another by their base, by the side 3.

Les dents 1 comportent à leur base un tenon 4 qui pénètre dans un des trous 5 effectués sur tout le pourtour circonfé- rentiel du support 2 de manière à le solidariser sur ce dernier. The teeth 1 have at their base a tenon 4 which penetrates into one of the holes 5 made over the entire circumferential periphery of the support 2 so as to secure it on the latter.

La figure 2 montre une autre application de l'invention avec des dents 6 intérieures fixées également par un tenon 7 sur le support 8. FIG. 2 shows another application of the invention with internal teeth 6 also fixed by a stud 7 on the support 8.

La figure 5 représente une autre application de L'invention sur un dispositif d'angle. Les dents 9 sont fixées sur le support 10 par collage. FIG. 5 represents another application of the invention on a corner device. The teeth 9 are fixed to the support 10 by gluing.

Le dispositif, objet de l'invention, peut être utilisé plus particulièrement pour la fabrication de pignons de bicyclette et autres véhicules mobiles, ainsi que pour les engrenages cylindriques à vis sans fin, d'angle, à crémaillère, hyperbololde, etc... et plus généralement pour tout dispositif à dents. The device, object of the invention, can be used more particularly for the manufacture of bicycle pinions and other mobile vehicles, as well as for cylindrical worm, angle, rack and pinion, hyperbolold, etc. gears. and more generally for any device with teeth.
