Abstract

Drive belt consists of a continuous loop of a core material -pref. a rubber or plastics - carrying a series of riders. The core is rectangular in cross-section and the exterior section of the riders is trapezoidal. At least one of the interior or exterior faces of the core loop has at least one pref. continuous rib which fits into a groove in the riders. In further detail the trapezoidal drive belt fits into a pulley with conical sides. The belt consists of riders on a core which has a cross-section essentially rectangular, flattened in the transverse direction, and an interior and an exterior face in contact with the riders, and two edges, symmetrical about the median of the pulley. Used esp. in systems where the speed is varied by the spacing of pulleys with conical flanges. Wear of the sides of the core is minimised because the sideways movement of the core inside the riders is avoided. Friction and noise are reduced.

Description

L'invention concerne les courroies de transmission dont la section a un contour extérieur sensiblement trapézovdal, qui sont constituées essentiellement d'au moins une âme fermée sur elle-même et d'un ensemble de cavaliers montés jointivement sur cette âme. The invention relates to transmission belts, the cross section of which has a substantially trapezoidal external contour, which essentially consist of at least one core closed on itself and of a set of jumpers mounted contiguously on this core.

De telles courroies sont utilisées par exemple dans certains variateurs de vitesse par écartement de poulies à joues coniques. Dans ces variateurs le couple moteur est transmis par compression des cavaliers les uns contre les autres entre les joues des poulies et le long de l'âme annulaire aplatie. Un glissement longitudinal apparaît entre l'âme et les cavaliers. Pour permettre ce mouvement on ménage des jeux entre les deux faces latérales ou rives et la face extérieure de l'âme d'une part et les cavaliers d'autre part. Such belts are used for example in certain speed variators by spacing of pulleys with conical cheeks. In these drives the motor torque is transmitted by compression of the jumpers against each other between the cheeks of the pulleys and along the flattened annular core. A longitudinal slide appears between the core and the riders. To allow this movement, clearances are provided between the two lateral faces or banks and the external face of the core on the one hand and the jumpers on the other hand.

La face intérieure de l'âme reste fréquemment au contact des cavaliers notamment dans les zones où la courroie est prise entre les joues des poulies. Ces jeux permettent un mouvement de va-et-vient transversal de l'âme par rapport aux cavaliers.The inner face of the core frequently remains in contact with the riders, especially in the areas where the belt is caught between the cheeks of the pulleys. These games allow a transverse back-and-forth movement of the core relative to the jumpers.

Ces mouvements relatifs provoquent des frottements, des échauffements et des usures de la face intérieure et des deux rives latérales de l'âme. These relative movements cause friction, overheating and wear of the inner face and the two lateral edges of the core.

La technique de fabrication de l'âme (qui est une courroie plate) permet de minimiser l'usure de la face intérieure de l'me. Mais la protection des rives entraîne un traitement individuel de chaque âme, par exemple en enrobant celle-ci d'un tissu protecteur adhérant à l'âme. The technique of manufacturing the core (which is a flat belt) makes it possible to minimize wear on the inner face of the core. However, the protection of the edges involves individual treatment of each core, for example by coating the latter with a protective fabric adhering to the core.

Le but de l'invention est de supprimer la protection individuelle des rives de l'âme au moment de la fabrication de celle-ci en évitant le mouvement relatif de va-et-vient de l'me à l'intérieur des cavaliers, ce mouvement étant la cause majeure de l'usure des rives de l'âme.  The object of the invention is to remove the individual protection of the strands of the core at the time of its manufacture by avoiding the relative back and forth movement of the core inside the jumpers, this movement being the major cause of the wear of the banks of the soul.

C'est ainsi que l'invention consiste à prévoir au moins sur une des faces (intérieure ou extérieure) de l'âme au moins une nervure longitudinale logée en permanence dans une découpure correspondante de chaque cavalier. Thus, the invention consists in providing at least on one of the faces (interior or exterior) of the core at least one longitudinal rib permanently housed in a corresponding cutout of each jumper.

Cette nervure peut être, de préférence, continue,
Le dessin, dont la description suit, illustre schématiquement, à titre d'exemples d'exécution, un certain nombre de variantes dont certaines préférentielles de l'invention.This rib may preferably be continuous,
The drawing, the description of which follows, schematically illustrates, by way of working examples, a certain number of variants, some of which are preferred, of the invention.

Sur ce dessin
- la figure 1 montre la section d'une courroie conforme à l'invention dans laquelle l'fime comporte sur sa face extérieure une nervure de centrage équidistante des rives de l'dme, cette nervure s'emboitant dans l'ouverture de montage des cavaliers
- la figure 2 montre la section d'une courroie dont llâme est munie selon l'invention de deux nervures sur-sa face extérieure, lesdites nervures étant équidistantes des deux rives et emboîtées dans l'ouverture de montage des cavaliers
- la figure 3 montre la section d'une courroie dont la face intérieure en contact avec les cavaliers est munie selon l'invention de nervures disposées sur la face intérieure de l'âme, ces nervures s'embortant dans des rainures correspondantes de la face des cavaliers en contact avec la face intérieure de l'âme, et
- les figures 4 et 5 montrent des sections de variantes à deux âmes.On this drawing
- Figure 1 shows the section of a belt according to the invention in which the file has on its outer face a centering rib equidistant from the banks of the dme, this rib fitting into the mounting opening of the riders
- Figure 2 shows the section of a belt which the core is provided according to the invention with two ribs on its outer face, said ribs being equidistant from the two banks and fitted into the mounting opening of the jumpers
- Figure 3 shows the section of a belt whose inner face in contact with the jumpers is provided according to the invention of ribs arranged on the inner face of the core, these ribs are supported in corresponding grooves on the face jumpers in contact with the inner face of the core, and
- Figures 4 and 5 show sections of variants with two cores.

Sur les figures 1 à 3 on voit une coupe partielle d'une poulie 1 à joues coniques dans laquelle est disposée une courroie 2 selon l'invention formée essentiellement de cavaliers 3 montés sur l'âme 4. L'âme 4, de section essentiellement rectangulaire aplatie dans le sens transversal, comporte une face extérieure 41, une face intérieure 42 en contact avec les cavaliers 3 et deux rives 43 équidistantes de l'axe de symétrie
XX' de la poulie 1 qui est également la médiane des deux rives 43. L'âme 4 peut comporter, en outre, une armature 44, par exemple longitudinale. les faces latérales extérieures 31 des cavaliers 3 sont inclinées l'une par rapport à l'autre pour s'appliquer comme un coin contre les joues coniques 11 de la poulie 1.Par ailleurs, les cavaliers 3 ont une section en fer à cheval dont les deux branches terminales 32 forment une ouverture de montage permettant d'introduire, au moment de l'assemblage de la courroie 2, l'âme 4 à l'intérieur des cavaliers 3.In Figures 1 to 3 we see a partial section of a pulley 1 with conical cheeks in which is disposed a belt 2 according to the invention essentially formed of jumpers 3 mounted on the core 4. The core 4, of essentially section rectangular flattened in the transverse direction, has an outer face 41, an inner face 42 in contact with the jumpers 3 and two edges 43 equidistant from the axis of symmetry
XX 'of the pulley 1 which is also the median of the two banks 43. The core 4 may further include a frame 44, for example longitudinal. the outer lateral faces 31 of the jumpers 3 are inclined with respect to each other to be applied as a wedge against the conical cheeks 11 of the pulley 1. Furthermore, the jumpers 3 have a horseshoe section, the the two end branches 32 form a mounting opening making it possible to introduce, when the belt 2 is assembled, the core 4 inside the jumpers 3.

Selon une première variante préférentielle de l'invention, la face extérieure 41 de l'âme 4 de la figure 1 comporte une nervure 5 équidistante des deux rives 43 de l'âme 4. La nervure 5 est logée entre les deux branches terminales 32 des cavaliers 3. Ainsi la nervure 5 empêche l'âme 4 de se mouvoir transversalement, c'est-à-dire parallèlement à l'axe de rotation (non représenté) de la poulie 1, par rapport aux cavaliers 3.Ceci permet de conserver un jeu constant et relativement élevé entre les rives 43 de l'8me 4 et la paroi correspondante 33 de l'inirieur des cavaliers 3, jeu empêchAnt,vn l'abence de- mouvements de va-et-vient transversal, le frottement des rives 43 de l'âme 4 sur les cavaliers 3. Il en résulte aussi que les rives 43 de l'âme 4 peuvent être dépourvues de tissu ou autre moyen de protection superficielle, alors que la face intérieure 42 de l'âme 4 ainsi que la face extérieure 41 avec la nervure 5 sont munies dans cet exemple d'une toile 6 de protection superficielle. According to a first preferred variant of the invention, the outer face 41 of the core 4 of FIG. 1 comprises a rib 5 equidistant from the two banks 43 of the core 4. The rib 5 is housed between the two end branches 32 of the jumpers 3. Thus the rib 5 prevents the core 4 from moving transversely, that is to say parallel to the axis of rotation (not shown) of the pulley 1, relative to the jumpers 3. This allows to keep a constant and relatively high clearance between the edges 43 of the 8th 4 and the corresponding wall 33 of the interior of the jumpers 3, preventing play, vn the absence of transverse back-and-forth movements, the friction of the edges 43 of the core 4 on the jumpers 3. It also follows that the edges 43 of the core 4 can be devoid of fabric or other surface protection means, while the inner face 42 of the core 4 as well as the outer face 41 with the rib 5 are provided in this example with a fabric 6 of surface protection.

Grâce à l'invention on peut-donc fabriquer en une seule pièce un ensemble de plusieurs âmes juxtaposées sur un moule cylindrique, puis refendre l'ensemble pour obtenir des âmes individuelles à rives non protégées.Thanks to the invention, it is therefore possible to manufacture in a single piece a set of several cores juxtaposed on a cylindrical mold, then to split the whole to obtain individual cores with unprotected edges.

La seconde variante préférentielle est représentée à la figure 2. L'âme 4 comporte des renforcements superficiels sur ses faces intérieure et extérieure, identiques à ceux de l'!me de la figure 1. Par contre, la face extérieure 41 de l'âme comporte conformément à l'invention deux nervures 51 et 52 équidistantes des rives 43. D'autre part, les branches terminales 32 des cavaliers 3 prennent appui dans l'arrondi réunissant chaque nervure 51, 52 aux rives 43 de l'Ame. Ceci permet une meilleure répartition des frottements des cavaliers 3 sur l'âme 4.  The second preferred variant is shown in FIG. 2. The core 4 has surface reinforcements on its interior and exterior faces, identical to those of the core of FIG. 1. On the other hand, the exterior face 41 of the core comprises, in accordance with the invention, two ribs 51 and 52 equidistant from the banks 43. On the other hand, the terminal branches 32 of the jumpers 3 are supported in the flare joining each rib 51, 52 to the banks 43 of the core. This allows a better distribution of the friction of the jumpers 3 on the core 4.

La troisième variante préférentielle (fig. 3) concerne une âme 4 dont la face intérieure 42 en contact avec les cavaliers 3 comporte des nervures 5. The third preferred variant (FIG. 3) relates to a core 4 whose inner face 42 in contact with the jumpers 3 includes ribs 5.

Conformément à l'invention ces nervures 5, équidistantes deux à deux des rives 43 de l'âme 4, sont logées dans des rainures 35 correspondantes des cavaliers 3. In accordance with the invention, these ribs 5, equidistant two by two from the edges 43 of the core 4, are housed in corresponding grooves 35 of the jumpers 3.

Les variantes des figures 2 et 3 permettent d'agrandir l'ouverture de montage des caliers 3, c'est-à-dire la distance transversale f entre les parties terminales 32 des cavaliers 3. The variants of FIGS. 2 and 3 make it possible to enlarge the mounting opening of the shims 3, that is to say the transverse distance f between the end parts 32 of the jumpers 3.

L'invention permet non seulement de choisir à volonté la distance ou le jeu e entre chaque rive 43 de l'âme 4 et la face intérieure correspondante 33 des cavaliers 3, mais aussi de conférer à la face intérieure 33 un profil arrondi qui permet de déformer les cavaliers 3 sans risque de rupture lors de leur montage sur l'âme 4, puisque grâce à l'invention les rives 43 de l'âme 4 ne sont plus amenées à porter sur les faces correspondantes 33 des cavaliers 3.The invention makes it possible not only to choose at will the distance or the clearance e between each bank 43 of the core 4 and the corresponding inner face 33 of the jumpers 3, but also to give the inner face 33 a rounded profile which makes it possible to deform the jumpers 3 without risk of breakage during their mounting on the core 4, since thanks to the invention the edges 43 of the core 4 are no longer brought to bear on the corresponding faces 33 of the jumpers 3.

Les cavaliers 3 sont, de préférence, des pièces en matière plastique injectée. L'armature de l'âme 4 peut être réalisée en tout matériau approprié, l'åme 4 elle-même en élastomère vulcanisé ou thermoplastique ou en polyuréthanne coulé ou injecté, avec des couches externes de protection 6 telles qu'un tissu croisé de coton ou de polyamide frictionné ou adhérisé. The jumpers 3 are preferably parts made of injected plastic. The frame of the core 4 can be made of any suitable material, the core 4 itself made of vulcanized or thermoplastic elastomer or of cast or injected polyurethane, with external protective layers 6 such as a cotton woven fabric or rubbed or bonded polyamide.

La figure 4 représente une section d'une courroie conforme à l'invention munie de deux âmes 301 et 302. Celles-cicomportent selon l'invention chacune une nervure 303, 304 sur les faces intérieures s'emboîtant chacune dans un évidement correspondant des cavaliers 504. FIG. 4 represents a section of a belt according to the invention provided with two cores 301 and 302. These consist according to the invention each of a rib 303, 304 on the interior faces each fitting into a corresponding recess of the jumpers 504.

La figure 5 représente une section d'une courroie conforme à l'invention à deux âmes 401 et 402 munies chacune d'une nervure 403, 404 sur leurs faces extérieures s'emboftant chacune dans l'ouverture de montage correspondanCe des cavaliers 505.  FIG. 5 represents a section of a belt according to the invention with two cores 401 and 402 each provided with a rib 403, 404 on their outer faces each fitting into the corresponding mounting opening of the jumpers 505.
