Description
Arbre de transmission rotatif. Rotary drive shaft.
On utilise fréquemment des arbres rotatifs pour transmettre de la puissance entre un organe moteur et un organe récepteur. Rotating shafts are frequently used to transmit power between a drive member and a receiver member.
Mais il arrive fréquemment que les positions des organes moteur et récepteur varient légèrement l'une par rapport à l'autre, soit angulairement, soit axialement. Pour permettre cette modification de la position relative des deux organes, on est obligé jusqu'à présent de prévoir un joint articulé à chacune des extrémités de l'arbre, l'un de ces joints articulé étant associé à un joint coulissant.However, it frequently happens that the positions of the motor and receiver members vary slightly with respect to each other, either angularly or axially. To allow this modification of the relative position of the two members, it is hitherto obliged to provide an articulated joint at each of the ends of the shaft, one of these articulated joints being associated with a sliding joint.
On connait des arbres de transmission tubulaires réalisés en matière composite, c'est-à-dire ep fibres enduites de résine organique. Ces arbres sont beaucoup plus légers que les arbres métal ligues; leur inertie étant, par suite, beaucoup plus faible, il est possible de les faire tourner à des vitesses plus élevées, donc de les soumettre à des couples beaucoup moins importants à puissance transmise égale. There are known tubular transmission shafts made of composite material, that is to say ep fibers coated with organic resin. These trees are much lighter than metal leagues; their inertia being, therefore, much lower, it is possible to rotate them at higher speeds, therefore subjecting them to much less torques at equal transmitted power.
La présente invention a pour objet un arbre de transmission du type ci-dessus qui permet de transmettre de la puissance d'un organe moteur à un organe récepteur, la position relative des deux organes étant variable, sans qu'il soit nécessaire d'associer à l'arbre des joints articulés ou coulissants. The subject of the present invention is a transmission shaft of the above type which makes it possible to transmit power from a driving member to a receiving member, the relative position of the two members being variable, without it being necessary to associate hinged or sliding joints at the shaft.
L'arbre de transmission selon l'invention, dont le corps comprend des nappes ou couches croisées de fibres à haut module, les fibres de ces nappes faisant un angle compris sensiblement entre 40 et 500 avec l'axe du tube et éventuellement pour augmenter sa rigidité axiale, d'au moins une nappe ou couche de fibres parallèles audit axe, est caractérisé en ce qu'il comporte au voisinage de chacune de ses extrémités, au moins une portion ondulée en forme de soufflet dont les flancs sont revetus de nappes de fibres à faible module, les fibres de ces nappes auxiliaires faisant un angle inférieur à 20 avec l'axe du tube. The transmission shaft according to the invention, the body of which comprises plies or crossed layers of high modulus fibers, the fibers of these plies making an angle of between approximately 40 and 500 with the axis of the tube and possibly to increase its axial rigidity, of at least one ply or layer of fibers parallel to said axis, is characterized in that it comprises, in the vicinity of each of its ends, at least one corrugated portion in the form of a bellows whose sides are coated with plies of low modulus fibers, the fibers of these auxiliary plies making an angle less than 20 with the axis of the tube.
La portion ondulée en forme de soufflet donne à l'extrémité du tube une certaine souplesse, aussi bien axialement qu'en flexion. The corrugated bellows-shaped portion gives the end of the tube a certain flexibility, both axially and in bending.
Les nappes auxiliaires empechent les fibres des nappes principales de se rompre lors du déplacement des extrémités du tube. Mais étant donné le faible module de ces fibres et tueur faible inclinaison par rapport à l'axe du tube, elles ne retirent pas leur souplesse aux flancs du soufflet.The auxiliary plies prevent the fibers of the main plies from breaking during the displacement of the ends of the tube. But given the low modulus of these fibers and the low inclination killer relative to the axis of the tube, they do not remove their flexibility from the sides of the bellows.
Dans la zone de grand diamètre de la portion ondulée, les fibres des nappes sont davantage écartées que dans le corps du tube. Si la largeur de cette zone est relativement importante, il y a avantage, pour conserver sensiblement le même poids de fibres par unité de surface, c'est-à-dire pour que cette zone de grand diamètre présente sensiblement la même rigidité à la torsion, à renforcer ladite zone par des nappes de fibres croisées, les fibres de ces nappes de renforcement faisant avec l'axe du tube un angle compris sensiblement entre 400 et 500. In the large diameter area of the corrugated portion, the fibers of the plies are further apart than in the body of the tube. If the width of this area is relatively large, it is advantageous to keep substantially the same weight of fibers per unit area, that is to say that this area of large diameter has substantially the same torsional rigidity , to reinforce said zone with sheets of crossed fibers, the fibers of these reinforcing sheets making with the axis of the tube an angle comprised substantially between 400 and 500.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation d'un arbre de transmission selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 représente en élévation avec arrachement partiel, l'une des portions d'extrémités de la bielle;
La Figure 2 est une vue semblable à la Figure 1 et montre comment l'extrémité de la bielle peut se déplacer.An embodiment of a transmission shaft according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 shows in elevation with partial cutaway, one of the end portions of the connecting rod;
Figure 2 is a view similar to Figure 1 and shows how the end of the connecting rod can move.
Tel qu'il est représenté au dessin, l'arbre 1 comporte un corps tubulaire 2 formé de nappes de carbone à haut module imprégné d'une résine organique, dans lesquelles les fibres sont inclinées par exemple à 450 par rapport à l'axe du tube et croisées d'une nappe à l'autre. Le module du carbone peut, par exemple, être de l'ordre de 35.000 daN/mm2. As shown in the drawing, the shaft 1 comprises a tubular body 2 formed of high modulus carbon sheets impregnated with an organic resin, in which the fibers are inclined for example at 450 with respect to the axis of the tube and crossed from one tablecloth to another. The carbon modulus can, for example, be of the order of 35,000 daN / mm2.
Au voisinage de chacune de ses extrémités, le tube 1 présente une portion ondulée en forme de soufflet dont la partie torique de plus grand diamètre 3 se raccorde au tube par des flancs obliques 4 et 5. Ce soufflet peut, par exemple, être réalisé en disposant une vessie dans le tube, avant polywérisation de la résine, et en plaçant l'ensemble dans un moule ayant la forme désirée. I1 suffit alors de chauffer le tube, afin de fluidiser la résine, et admet tre une pression dans la vessie, par exemple l'aide d'un fluide approprié. In the vicinity of each of its ends, the tube 1 has a corrugated portion in the form of a bellows whose toric part of larger diameter 3 is connected to the tube by oblique sides 4 and 5. This bellows can, for example, be made in placing a bladder in the tube, before polywerization of the resin, and placing the assembly in a mold having the desired shape. It is then sufficient to heat the tube, in order to fluidize the resin, and admits being a pressure in the bladder, for example using an appropriate fluid.
La partie de grand diamètre 3 du soufflet est recouverte de nappes supplémentaires croisées de carbone a haut module, a fibres inclinées a 45 , afin d'avoir sensiblement le méme poids de carbone par unité de surface que le corps 2 et présenter ainsi sensiblement la mGme rigidité. A titre d'exemple, si le corps 2 est formé de deux nappes croisées et si le diamètre de la partie 3 est sensiblement égal au double de celui du corps 2, la partie 3 pourra entre renforcée par deux nappes a.roi- sées. The large diameter portion 3 of the bellows is covered with additional crossed plies of high modulus carbon, with fibers inclined at 45, in order to have substantially the same weight of carbon per unit area as the body 2 and thus present substantially the same size. rigidity. By way of example, if the body 2 is formed of two crossed plies and if the diameter of the part 3 is substantially equal to twice that of the body 2, the part 3 may be reinforced by two crossed plies.
Les flancs 4 et 5 du soufflet sont revêtus de nappes supplémentaires de carbone à haute résistance, donc a faible module, dans lesquelles les fibres de carbone font, avec l'axe du tube, un angle faible inférieur a 100; le module du carbone peut, par exemple, n'être que de 20.000 daN/mm2 Les nappes de fibres de carbone peuvent éventuellement être remplaces par des nappes de fibres de verre ou de produit connu sous le nom de
Kevlar. Du fait de leur nature et de leur disposition, ces nappes conservent aux flancs leur souplesse, mais évitent aux fibres des nappes de carbone principales de se rompre lors des déformations.The sides 4 and 5 of the bellows are coated with additional sheets of high-strength carbon, therefore with low modulus, in which the carbon fibers form, with the axis of the tube, a small angle less than 100; the carbon modulus can, for example, be only 20,000 daN / mm2 The layers of carbon fibers can optionally be replaced by layers of glass fibers or of a product known under the name of
Kevlar. Due to their nature and their arrangement, these layers retain their flexibility on the sides, but prevent the fibers of the main carbon layers from breaking during deformations.
La référence 6 désigne un disque de fixation a l'organe moteur ou récepteur, qui est prévu à l'extrémité du tube et fait partie intégrante de celui cil
Après polymérisation de la résine, on obtient un arbre mo- nolithique dans lequel aucune des fibres travaillantes n'est coupée et dont les extrémités peuvent se déplacer légèrement aussi bien axialement qu'angulairement, comme le montre la Fifure 2, grâce à la souplesse en flexion des flancs 4 et 5 qui conservent cependant leur rigidité a la torsion.The reference 6 designates a disc for fixing to the motor or receiver member, which is provided at the end of the tube and is an integral part of the eyelash
After polymerization of the resin, a monolithic shaft is obtained in which none of the working fibers is cut and the ends of which can move slightly both axially and angularly, as shown in Fifure 2, thanks to the flexibility in bending of the sides 4 and 5 which, however, retain their torsional rigidity.
Si la partie 3 du soufflet a une très faible longueur, c'est-a-dire si ce soufflet a une section relativement pointue, il est possible de ne pas prévoir de nappes de renforcement. If part 3 of the bellows has a very short length, that is to say if this bellows has a relatively pointed section, it is possible not to provide reinforcing plies.
I1 va de soi que la présente invention ne doit pas entre considerée comme limitée au mode de réalisation décrit et représenté, mais en couvre, aucontraire, toutes les variantes. I1 goes without saying that the present invention should not be regarded as limited to the embodiment described and shown, but covers, on the contrary, all variants.
C'est ainsi, par exemple, qu'au lieu du disque 6, on peut prévoir tout autre dispositif de fixation, par exemple un mandrin tubulaire qui peut être collé ou fixe mécaniquement à un arbre. Thus, for example, instead of the disc 6, one can provide any other fastening device, for example a tubular mandrel which can be glued or mechanically fixed to a shaft.
Le soufflet pourrait comporter plus d'une ondulation. Pour augmenter la rigidit6-axiale du corps 1, celui-ci pourrait comporter une ou plusieurs nappes de fibres-parallèles à l'axe de ce corps. The bellows could have more than one corrugation. To increase the axial rigidity of the body 1, the latter could comprise one or more plies of fibers-parallel to the axis of this body.
