Description

Dispositif de montage d'une courroie entre deux poulies en présence d'un galet anti-battement [0001 La présente invention concerne un dispositif de montage d'une courroie entre au moins deux poulies, la courroie étant maintenue par un galet anti-battement. La courroie peut être par exemple la courroie accessoire d'un moteur thermique d'un véhicule automobile. [0002] L'extrémité du vilebrequin d'un moteur thermique d'un véhicule automobile comporte généralement une poulie qui est reliée par une courroie à des poulies de divers éléments tels qu'un alternateur ou une pompe à eau. FIELD OF THE INVENTION The present invention relates to a device for mounting a belt between at least two pulleys, the belt being held by an anti-flapping roller. The belt may be for example the accessory belt of a combustion engine of a motor vehicle. The end of the crankshaft of a combustion engine of a motor vehicle generally comprises a pulley which is connected by a belt to pulleys of various elements such as an alternator or a water pump.

La mise en place de cette courroie, généralement appelée courroie accessoire, est une opération assez délicate. Il existe donc des dispositifs de montage de cette courroie. On peut citer par exemple la demande de brevet FR 2 909 430 qui concerne un dispositif de montage d'une courroie muni d'un système de fixation par billes pour le montage d'une courroie élastique. The introduction of this belt, generally called accessory belt, is a fairly delicate operation. There are therefore devices for mounting this belt. For example, patent application FR 2 909 430 relates to a device for mounting a belt provided with a ball-fixing system for mounting an elastic belt.

Ce dispositif convient bien lorsqu'il s'agit de monter une courroie entre deux poulies. [0003] Dans certains cas, les façades moteurs peuvent être équipées d'un galet anti-battement pour maintenir la courroie afin qu'elle ne vibre pas. Ce galet est positionné pour presser la courroie entre les deux poulies. Le montage de la courroie devient alors plus compliqué et les dispositifs existants ne résolvent pas ce problème. C'est ce que la présente invention propose de faire. [0004] Le dispositif proposé par la présente invention comporte un bâti qui peut être attaché au galet anti-battement et des moyens de guidage de la 25 courroie. [0005] De façon plus précise, la présente invention concerne un dispositif de montage d'une courroie entre au moins deux poulies, ladite courroie étant maintenue par un galet anti-battement dont l'axe de rotation est fixé à un support, tel que le carter d'un moteur thermique. Selon l'invention, le dispositif comporte : • un bâti de forme allongée, ayant deux extrémités et comportant à l'une de ses extrémités une pièce en forme de fourche destinée à être insérée autour dudit axe du galet anti-battement et entre ledit support et ledit galet anti-battement ; • des moyens de montage dudit dispositif comportant un galet de maintien solidaire dudit bâti et destiné à être placé en vis-à-vis du galet anti-battement, lesdits moyens de montage étant destinés à prendre en étau ledit galet anti-battement entre ladite pièce en forme de fourche et ledit galet de maintien, et • des moyens de guidage de ladite courroie solidaire dudit bâti. [0006] Selon un mode de réalisation : • Ledit galet de maintien est mobile entre une position de repos et une position de fixation pour laquelle ledit galet de maintien est rendu solidaire dudit galet anti-battement en exerçant une pression latéralement contre ledit galet anti-battement. • Lesdits moyens de montage comportent des moyens de déplacement dudit galet de maintien entre lesdites positions de repos et de fixation, et lesdits moyens de déplacement peuvent comporter un axe de translation supporté par ledit bâti et mobile longitudinalement entre lesdites positions de repos et de fixation. Ledit galet de maintien peut être fixé à l'une des deux extrémités dudit axe de translation et peut être déplacé en rotation autour dudit axe. L'autre extrémité dudit axe peut avantageusement comporter des moyens de translation dudit axe. Lesdits moyens de translation peuvent comporter une poignée. • Lesdits moyens de guidage de ladite courroie comportent au moins un roulement dont l'axe de rotation est solidaire dudit bâti. Ledit axe de rotation dudit roulement peut être situé dans un plan perpendiculaire à l'axe de translation et ledit roulement est avantageusement disposé sensiblement en regard de la jante dudit galet de maintien. De façon avantageuse, lesdits moyens de guidage de ladite courroie comportent deux roulements. [0007] Lesdites deux poulies peuvent être constituées par la poulie vilebrequin et la poulie alternateur d'un moteur thermique. [000si Ladite courroie, qui peut être élastique, peut être la courroie accessoire d'un moteur de véhicule automobile. [0009] D'autres avantages et caractéristiques de l'invention apparaîtront au cours de la description qui suit de plusieurs modes de réalisation de l'invention, donnés à titre d'exemples non limitatifs, en référence aux dessins annexés et sur lesquels : • la figure 1 montre un moteur thermique muni des poulies habituelles et d'un galet anti-battement ; • la figure 2 est une vue en trois dimensions du dispositif de l'invention ; • la figure 3 représente le dispositif de l'invention en coupe longitudinale ; • la figure 4 est une vue de dessus du dispositif ; • la figure 5 est une vue de coté du dispositif ; • la figure 6 illustre le montage de la courroie ; et • la figure 7 montre en détails le galet de maintien et un roulement de guidage de la courroie. [0010] Les dessins annexés pourront non seulement servir à compléter l'invention, mais aussi contribuer à sa définition, le cas échéant. [0011] La figure 1 illustre une application de l'invention au domaine automobile. Sur cette figure, un moteur thermique 10 comprend de façon classique une poulie 11 fixée à l'extrémité du vilebrequin, une poulie 12 fixée en bout d'arbre d'une pompe à eau, une poulie 13 d'un alternateur 14 et un galet anti-battement 15. La poulie vilebrequin 11 comporte deux plans de courroie, l'un accueillant une courroie 16 reliée à la poulie pompe à eau 12 et l'autre étant occupé par une courroie 17 reliant les poulies 11 et 13. La courroie 17 est maintenue tendue et empêchée de vibrer, ou de battre, grâce au galet anti-battement 15 fixé sur le carter moteur. La courroie 17, souvent appelée courroie accessoire, peut avantageusement être une courroie élastique (par exemple avec 5% environ de déformation maximale). L'axe 19 du galet anti-battement 15 est fixé sur un support 18, le carter du moteur par exemple. Le galet anti-battement complique le montage de la courroie 17. Le problème résolu par l'invention est de proposer un dispositif permettant de monter la courroie 17 en présence d'un galet anti-battement. [0012] Le mode préféré de réalisation de l'invention est décrit ci-après en regard des figures 2 à 5. Le dispositif 20 comporte un bâti 21, réalisé par exemple en aluminium. Ce bâti, qui est de forme allongée, comporte deux extrémités 22 et 23. L'extrémité 22 se termine par une fourche 24; l'autre extrémité 23 comporte un pilier 25 muni d'un passage destiné à loger un axe de translation 26. [0013] Le dispositif 20 comporte des moyens 27 permettant de le monter solidairement au moteur de façon à chausser la courroie 17 sur le galet antibattement. Ces moyens 27 comportent un galet de maintien 28 fixé à l'extrémité de l'axe de translation 26, le galet 28 pouvant tourner librement autour de cet axe de translation 26 grâce à un roulement à billes 29 (figure 3, qui représente le dispositif 20 en coupe selon l'axe de translation 26). Le galet de maintien 28 a sensiblement le même diamètre que le galet antibattement 15, ou un diamètre légèrement supérieur. L'axe 26 est maintenu sur le bâti 21 par le pilier 25 et par un support 30 traversé par un logement 31, lequel accueille une bague de translation 32 (figure 3) dans laquelle peut coulisser l'axe 26. [0014] Le dispositif 20 comporte aussi des moyens 33 permettant de déplacer longitudinalement (dans le sens de la flèche 34) l'axe de translation 26 et le galet de maintien 28. Ces moyens comprennent une poignée 35 à trois points d'articulation, qui transforme un mouvement de rotation (de haut en bas pour la poignée) en un mouvement de translation (pour l'axe 26). Ce type de poignée est par exemple décrit dans le brevet US 3,237,463. La poignée peut prendre deux positions: une position de repos 36 et une position de fixation 37 permettant de solidariser le dispositif 20 au moteur 10. Pour ce faire, la fourche 24 du dispositif 20 est positionnée autour de l'axe 19 du galet anti-battement 15, entre le support 18 (le carter du moteur) et le galet anti-battement 15. En abaissant la poignée 35 en position de fixation 37, l'axe 26 et le galet de maintien 28 se déplacent dans le sens de la flèche 34, le galet anti-battement étant alors pris en étau entre la fourche 24 et le galet de maintien 34. Ce dernier vient presser le galet anti-battement 15, l'une des deux joues du galet de maintien venant en regard et contre une joue du galet anti-battement. Le dispositif 20 est alors attaché au galet antibattement et les deux galets de maintien et anti-battement peuvent alors tourner ensemble, autour de l'axe de translation 26 pour le galet de maintien. Pour désolidariser le dispositif 20 du galet anti-battement, il suffît de relever la poignée 35 en position de repos. [0015] La figure 4 est une vue de dessus du dispositif 20, alors que la figure 5 est une vue de coté (du coté de la poignée 35). Le dispositif 20 comporte des moyens de guidage 40 (figures 4 et 5) de la courroie destinée à être montée autour des poulies vilebrequin et accessoire et du galet anti- battement. Les moyens de guidage comportent au moins un roulement 41 dont l'axe de rotation 46 est fixé au bâti 21 à l'extrémité d'un bras 42. De façon avantageuse, lesdits moyens de guidage comportent un deuxième roulement 43 dont l'axe de rotation est fixé au bâti 21 à l'extrémité d'un bras 44. Les roulements 41 et 43 sont situés de part et d'autre du galet de maintien 28 et leurs axes de rotation sont situés sensiblement dans un plan perpendiculaire à l'axe de translation 26. Les roulements sont situés sensiblement en regard de la jante 45 du galet de maintien 28. Au moins l'un desdits roulements 41, 43 est réalisé en acier. [0016] Les figures 6 et 7 montrent l'utilisation du dispositif 20. Sur la figure 6, la courroie accessoire 17 est en cours de montage sur la poulie vilebrequin 11 à l'aide d'un dispositif 60 conforme à celui décrit dans la demande de brevet FR 2 909 430 intitulée "Dispositif de montage d'une courroie muni d'un système de fixation par billes". Le dispositif 20 conforme à l'invention est solidarisé au galet anti-battement 15, la fourche 24 entourant partiellement l'axe 19 du galet anti-battement 15 et le galet de maintien 28 étant pressé contre le galet anti-battement 15, la poignée 35 ayant été abaissée. La courroie accessoire 17 est guidée sur la jante du galet antibattement 15 par le roulement 41 fixé sur le bras 42. [0017] Sur la figure 7, le dispositif 20 de l'invention est en position de fixation, c'est-à-dire attaché au galet anti-battement 15. Ce dernier est pressé contre le galet de maintien 28, lequel a un diamètre légèrement supérieur à celui du galet anti-battement 15. Le roulement 41 guide la courroie accessoire 17. [0018] Sans le maintien de la courroie accessoire par au moins un 25 roulement, la courroie a tendance à s'échapper du galet anti-battement et le montage est très difficile, sinon impossible. [0019] D'autres modes de réalisation que celui décrit et représenté peuvent être conçus par l'homme du métier sans sortir du cadre de la présente invention. Par exemple, le mode de réalisation décrit est dans le domaine de l'automobile, mais l'invention peut être appliquée à d'autres domaines dès qu'il s'agit de monter une courroie entre deux poulies en présence d'un galet anti-battement. This device is well suited for mounting a belt between two pulleys. In some cases, the engine facades may be equipped with an anti-flap roller to maintain the belt so that it does not vibrate. This roller is positioned to press the belt between the two pulleys. The assembly of the belt then becomes more complicated and the existing devices do not solve this problem. This is what the present invention proposes to do. [0004] The device proposed by the present invention comprises a frame which can be attached to the anti-beating roller and means for guiding the belt. More specifically, the present invention relates to a device for mounting a belt between at least two pulleys, said belt being held by an anti-beat roller whose axis of rotation is fixed to a support, such as the housing of a heat engine. According to the invention, the device comprises: a frame of elongate shape, having two ends and having at one of its ends a fork-shaped piece intended to be inserted around said axis of the anti-beat roller and between said support and said anti-beat roller; • means for mounting said device comprising a holding roller secured to said frame and intended to be placed opposite the anti-beat roller, said mounting means being intended to grip said anti-beat roller between said piece fork-shaped and said holding roller, and means for guiding said belt secured to said frame. According to one embodiment: • said holding roller is movable between a rest position and a fixing position for which said holding roller is secured to said anti-beat roller by exerting a pressure laterally against said anti-backing roller; beat. • Said mounting means comprise means for moving said holding roller between said resting and fixing positions, and said moving means may comprise a translation axis supported by said frame and movable longitudinally between said resting and fixing positions. Said holding roller can be fixed at one of the two ends of said translation axis and can be moved in rotation about said axis. The other end of said axis may advantageously comprise means for translating said axis. Said translation means may comprise a handle. Said means for guiding said belt comprise at least one bearing whose axis of rotation is integral with said frame. Said axis of rotation of said bearing may be located in a plane perpendicular to the axis of translation and said bearing is advantageously disposed substantially opposite the rim of said retaining roller. Advantageously, said guide means of said belt comprise two bearings. [0007] Said two pulleys can be constituted by the crankshaft pulley and the alternator pulley of a heat engine. [000si] Said belt, which can be elastic, can be the accessory belt of a motor vehicle engine. Other advantages and features of the invention will become apparent from the following description of several embodiments of the invention, given by way of non-limiting examples, with reference to the accompanying drawings and in which: FIG. 1 shows a heat engine equipped with the usual pulleys and an anti-beat roller; FIG. 2 is a three-dimensional view of the device of the invention; • Figure 3 shows the device of the invention in longitudinal section; FIG. 4 is a view from above of the device; Figure 5 is a side view of the device; • Figure 6 illustrates the mounting of the belt; and Figure 7 shows in detail the holding roller and a guide bearing of the belt. The accompanying drawings may not only serve to complete the invention, but also contribute to its definition, if any. Figure 1 illustrates an application of the invention to the automotive field. In this figure, a heat engine 10 conventionally comprises a pulley 11 attached to the end of the crankshaft, a pulley 12 fixed at the end of a water pump shaft, a pulley 13 of an alternator 14 and a roller The crankshaft pulley 11 has two belt planes, one accommodating a belt 16 connected to the water pump pulley 12 and the other being occupied by a belt 17 connecting the pulleys 11 and 13. The belt 17 is kept taut and prevented from vibrating or beating, thanks to the anti-flapping roller 15 fixed on the crankcase. The belt 17, often called accessory belt, may advantageously be an elastic belt (for example with about 5% of maximum deformation). The axis 19 of the anti-beat roller 15 is fixed on a support 18, the motor housing for example. The anti-flapping roller complicates the mounting of the belt 17. The problem solved by the invention is to provide a device for mounting the belt 17 in the presence of an anti-flap roller. The preferred embodiment of the invention is described below with reference to Figures 2 to 5. The device 20 comprises a frame 21, made for example of aluminum. This frame, which is elongated, has two ends 22 and 23. The end 22 ends with a fork 24; the other end 23 comprises a pillar 25 provided with a passage for housing a translation axis 26. The device 20 comprises means 27 for mounting it integrally to the motor so as to fit the belt 17 on the roller Debouncing. These means 27 comprise a holding roller 28 fixed at the end of the translation axis 26, the roller 28 being able to rotate freely about this translation axis 26 by virtue of a ball bearing 29 (FIG. 3, which represents the device 20 in section along the axis of translation 26). The retaining roller 28 has substantially the same diameter as the anti-roll wheel 15, or a slightly larger diameter. The axis 26 is held on the frame 21 by the pillar 25 and a support 30 traversed by a housing 31, which accommodates a translation ring 32 (Figure 3) in which the axis 26 can slide. 20 also comprises means 33 for moving longitudinally (in the direction of the arrow 34) the translation axis 26 and the retaining roller 28. These means comprise a handle 35 with three points of articulation, which transforms a movement of rotation (from top to bottom for the handle) in a translation movement (for the axis 26). This type of handle is for example described in US Patent 3,237,463. The handle can take two positions: a rest position 36 and a fixing position 37 for securing the device 20 to the motor 10. To do this, the fork 24 of the device 20 is positioned around the axis 19 of the anti-friction roller. beat 15, between the support 18 (the motor housing) and the anti-flap roller 15. By lowering the handle 35 in the fixing position 37, the shaft 26 and the holding roller 28 move in the direction of the arrow 34, the anti-beating roller being then caught in a vice between the fork 24 and the holding roller 34. The latter presses the anti-beat roller 15, one of the two cheeks of the holding roller coming opposite and against a plays anti-beat roller. The device 20 is then attached to the anti-roll wheel and the two support and anti-beat rollers can then rotate together about the translation axis 26 for the holding roller. To separate the device 20 from the anti-flap roller, it is sufficient to raise the handle 35 in the rest position. Figure 4 is a top view of the device 20, while Figure 5 is a side view (the side of the handle 35). The device 20 comprises guide means 40 (FIGS. 4 and 5) of the belt intended to be mounted around the crankshaft and accessory pulleys and the anti-beat roller. The guide means comprise at least one bearing 41 whose axis of rotation 46 is fixed to the frame 21 at the end of an arm 42. Advantageously, said guide means comprise a second bearing 43 whose axis of rotation is fixed to the frame 21 at the end of an arm 44. The bearings 41 and 43 are located on either side of the holding roller 28 and their axes of rotation are located substantially in a plane perpendicular to the axis 26. The bearings are located substantially opposite the rim 45 of the holding roller 28. At least one of said bearings 41, 43 is made of steel. Figures 6 and 7 show the use of the device 20. In Figure 6, the accessory belt 17 is being mounted on the crankshaft pulley 11 with a device 60 according to that described in the patent application FR 2,909,430 entitled "Device for mounting a belt provided with a ball fixing system". The device 20 according to the invention is secured to the anti-beat roller 15, the fork 24 partially surrounding the axis 19 of the anti-beat roller 15 and the holding roller 28 being pressed against the anti-beat roller 15, the handle 35 having been lowered. The accessory belt 17 is guided on the rim of the anti-roll wheel 15 by the bearing 41 fixed on the arm 42. In FIG. 7, the device 20 of the invention is in the fixing position, that is to say The latter is pressed against the holding roller 28, which has a diameter slightly greater than that of the anti-beating roller 15. The bearing 41 guides the accessory belt 17. [0018] Without the maintenance of the accessory belt by at least one bearing, the belt tends to escape the anti-beating roller and mounting is very difficult, if not impossible. Other embodiments than that described and shown may be designed by those skilled in the art without departing from the scope of the present invention. For example, the embodiment described is in the automotive field, but the invention can be applied to other areas when it comes to mounting a belt between two pulleys in the presence of a roller anti -beat.
