Abstract

System for driving by a belt, band or the equivalent, passing over at least one pulley, which may or may not be a drive pulley, characterised in that it consists of a belt or band 1 equipped with lateral elements 2 and of at least one pulley 5 also equipped with lateral elements 3 interacting with the elements of the belt, with a view to driving it. The lateral elements of the belt advantageously consist of projections such as teeth or studs which engage in a toothing 4 on the pulley or pulleys over which the belt passes.

Description

La présente invention concerne un système perfectionné d'entraînement par courroie ou bande, destiné en particulier à la transmission d'une force motrice. The present invention relates to an improved belt or belt drive system, intended in particular for the transmission of a motive force.

Les systèmes connus d'entraînement ou de transmission de force motrice utilisent généralement des chaînes métalliques rigides ou articulées, transmettant la force motrice par entratnement de pignons ou roues dentées, ou bien des courroies souples qui peuvent être lisses sur leur face interne, entratnant ainsi des poulies lisses ou à gorge, ou bien des courroies munies de crans sur leur face interne entraînant alors des poulies ou arbres également crantés pour les recevoir. Known drive or drive force transmission systems generally use rigid or articulated metal chains, transmitting the drive force by driving pinions or cogwheels, or else flexible belts which can be smooth on their internal face, thus driving smooth or grooved pulleys, or belts provided with notches on their internal face then causing pulleys or shafts also notched to receive them.

Ces deux systèmes de transmission présentent certains inconvénients - 1 'entratnement par chaîne provoque d'importants bruits de fonctionnement
ainsi que des phénomènes d'usure rapide en raison de la corrosion du
métal, dans le cas par exemple du travail en terre, ou bien des phéno
mènes de grippage ; - l'entralnement par courroie dans les applications usuelles, présente
des phénomènes de glissement quand les courroies sont lisses et n'of
fre pas beaucoup plus de sécurité dans les cas de crantage interne en
raison des variations de la vitesse imprimée au système et des charges
de transmission.These two transmission systems have certain drawbacks - chain drive causes significant operating noise
as well as rapid wear phenomena due to corrosion of the
metal, in the case for example of working in soil, or pheno
seizing patches; - belt entrainment in usual applications, present
slip phenomena when the belts are smooth and do not
fre not much more security in the case of internal notching in
due to variations in system speed and loads
of transmission.

L'invention a pour objet un système perfectionné dont la conception permet de remédier aux inconvénients présentés par les systèmes connus d entraînement au moyen de bandes et courroies souples, permettant ainsi de substituer, dans de nombreuses applications, la courroie ou bande souple à la channe, en raison de la sécurité d'entraSnement qu'assure ce système. The subject of the invention is an improved system the design of which overcomes the drawbacks presented by known drive systems by means of flexible bands and belts, thus making it possible to replace, in many applications, the flexible belt or band for the channe , due to the training safety that this system provides.

Le système suivant l'invention est essentiellement caractérisé en ce qu'il est constitué par une courroie, ou bande, munie d'éléments latéraux et d'au moins une poulie, également munie d'éléments latéraux coopérant avec ceux de la courroie, en vue de l'entratnement de cette dernière. The system according to the invention is essentially characterized in that it is constituted by a belt, or strip, provided with lateral elements and at least one pulley, also provided with lateral elements cooperating with those of the belt, in view of the training of the latter.

Suivant une forme préférée de réalisation de l'invention, les éléments latéraux de la courroie sont constitués par des saillies, telles que dents ou plots, qui viennent en prise dans une denture présentée par la ou les poulies sur laquelle ou sur lesquelles passe la courroie.  According to a preferred embodiment of the invention, the lateral elements of the belt consist of projections, such as teeth or studs, which engage in a toothing presented by the pulley (s) over which or over which the belt passes. .

La description qui va suivre se rapporte à un exemple,non limitatif, de réalisation de l'invention appliqué à une machine agricole servant au ramassage du mals, étant observé que, bien évidemment, l'invention n'est pas limitée à une telle application. The description which follows relates to a nonlimiting example of an embodiment of the invention applied to an agricultural machine used for picking up the evils, it being observed that, of course, the invention is not limited to such an application. .

Au cours de cette description on se réfère au dessin cijoint sur lequel la Fig. 1 est une vue en élévation du système, la Fig. 2 est une coupe suivant II/II de la Fig. 1, la Fig. 3 est une vue partielle en élévation de la courroie, la Fig 4 -est une coupe suivant III/III de la Fig. 3, et la Fig. 5 est une vue en plan de la courroie. In the course of this description, reference is made to the attached drawing in which FIG. 1 is an elevational view of the system, FIG. 2 is a section along II / II of FIG. 1, FIG. 3 is a partial view in elevation of the belt, FIG. 4 is a section along III / III of FIG. 3, and FIG. 5 is a plan view of the belt.

Dans l'exemple traité la courroie ou bande 1 est munie, sur chacun de ses bords, de saillies 2 dont les formes et dimensions sont telles qu'elles engrènent entre les éléments 3 d'une denture 4 que présente, faisant saillie également sur chacun de ses bords, la poulie 5. In the example treated, the belt or strip 1 is provided, on each of its edges, with projections 2, the shapes and dimensions of which are such that they mesh between the elements 3 of a toothing 4 that is present, also projecting on each from its edges, the pulley 5.

Comme on le voit sur la Fig. 4, les éléments latéraux de la courroie sont des sortes de pastilles, avantageusement de la même matière que la courroie et de préférence venues de fabrication avec cette dernière. As seen in Fig. 4, the lateral elements of the belt are sort of pellets, advantageously of the same material as the belt and preferably come from manufacturing with the latter.

Elles sont, en saillie, de même largeur que la courroie et leur épaisseur est choisie en fonction des conditions dans lesquelles est placé le système. They are projecting, of the same width as the belt and their thickness is chosen according to the conditions in which the system is placed.

Les matériaux utilisés pour réaliser la bande ou courroie peuvent être quelconques - par exemple caoutchouc ou toute matière souple résistante, à l'état naturel ou armée. The materials used to make the strip or belt can be any - for example rubber or any resilient flexible material, in the natural or reinforced state.

Quant à la poulie, elle peut être d'un type quelconque, auquel il suffit d'adapter les éléments latéraux coopérant avec les éléments équivalents de la courroie ou bande. As for the pulley, it can be of any type, to which it suffices to adapt the lateral elements cooperating with the equivalent elements of the belt or strip.

On voit de ce qui précède, que le système suivant l'invention permet de réaliser un entralnement sans faille quelles que soient les conditions dans lesquelles ce système est placé. It can be seen from the above that the system according to the invention makes it possible to carry out flawless training whatever the conditions under which this system is placed.

Le système suivant 1 invention peut donc être utilisé dans de nombreux domaines. I1 est, cependant, particulièrement intéressant en ce qui concerne l'équipement de machines agricoles travaillant sur le sol, par exemple les machines servant au ramassage du mais. The system according to the invention can therefore be used in numerous fields. I1 is, however, particularly interesting as regards the equipment of agricultural machines working on the ground, for example the machines used for collecting corn.

Dans une telle machine la bande ou courroie 1 comporte, un bec cueilleur la , comme on le voit sur la Fig. 1.  In such a machine, the strip or belt 1 comprises a picking nozzle 1a, as seen in FIG. 1.

Bien entendu, l'invention n'est nullement limitée, non seulement à l'application dont il vient d'être question, mais encore à la forme de réalisation décrite et représentée, car elle peut donner lieu à de nombreuses variantes, touchant notamment la forme et la dimension des éléments dont est munie la bande ou courroie, le type de poulie d'entratnement sur laquelle elle passe, sans que, ce faisant on s'écarte de son principe.  Of course, the invention is in no way limited, not only to the application which has just been mentioned, but also to the embodiment described and shown, since it can give rise to numerous variants, affecting in particular the shape and size of the elements with which the band or belt is fitted, the type of drive pulley over which it passes, without thereby departing from its principle.
