Description

Dispositif de variation de vitesse d'un groupe motopropulseur pour l'entraînement d'un véhicule automobile, notamment de type hybride.  Device for varying the speed of a powertrain for driving a motor vehicle, particularly of the hybrid type.
La présente invention se rapporte à un dispositif de variation de vitesse d'un groupe motopropulseur pour l'entraînement d'un véhicule automobile de type hybride.  The present invention relates to a speed variation device of a powertrain for driving a hybrid type of motor vehicle.
Comme cela est déjà connu, ce type de véhicule comporte un groupe motopropulseur qui utilise seul ou en combinaison, comme mode d'entraînement en traction/propulsion, un moteur thermique à combustion interne avec un dispositif de variation de vitesse, et une machine rotative motrice/génératrice, généralement un moteur électrique, reliée à une source électrique, telle qu'une ou plusieurs batteries. Cette combinaison a pour avantage d'optimiser les performances de ce véhicule, notamment en réduisant les émissions de polluants dans l'atmosphère et en diminuant la consommation en carburant. As is already known, this type of vehicle comprises a powertrain that uses alone or in combination, as a traction / propulsion drive mode, an internal combustion engine with a speed variation device, and a rotary power machine. generator, generally an electric motor, connected to an electrical source, such as one or more batteries. This combination has the advantage of optimizing the performance of this vehicle, including reducing emissions of pollutants into the atmosphere and reducing fuel consumption.
Ainsi, lorsque l'on souhaite déplacer le véhicule avec un couple important sur une grande plage de vitesses tout en limitant l'émission de polluants la génération de gaz d'échappement et de bruit, comme dans un site urbain, l'utilisation de la machine électrique est privilégiée pour entraîner en déplacement ce véhicule. Thus, when it is desired to move the vehicle with a large torque over a wide range of speeds while limiting the emission of pollutants the generation of exhaust gas and noise, as in an urban site, the use of the electric machine is preferred to drive on the move this vehicle.
Par contre, le moteur thermique est utilisé pour déplacer ce véhicule lors d'utilisations où une puissance d'entraînement élevée et une grande autonomie de fonctionnement sont demandées.  On the other hand, the engine is used to move this vehicle for uses where high driving power and a long operating autonomy are required.
Généralement comme cela est mieux illustré sur les figures 1 et 2 illustrant l'art antérieur, ce type de groupe motopropulseur comprend un moteur à combustion interne 10 dont le vilebrequin 12 est relié à un arbre moteur 14 d'un dispositif de variation de vitesse 1 6 qui transmet son mouvement de rotation à un arbre récepteur 18 accouplé à l'essieu moteur 20 du véhicule par un pont différentiel 22. Cet arbre récepteur 18 est également relié, ici par l'intermédiaire d'une bande 24 refermée sur elle-même, comme une courroie ou une chaîne, au rotor 26 d'une machine motrice/génératrice 28, comme un moteur électrique, hydraulique ou pneumatique, qui est rapportée et fixée sur le carter du dispositif de variation de vitesse. Generally as best illustrated in Figures 1 and 2 illustrating the prior art, this type of powertrain comprises an internal combustion engine 10 whose crankshaft 12 is connected to a drive shaft 14 of a speed variation device 1 6 which transmits its rotational movement to a receiver shaft 18 coupled to the drive axle 20 of the vehicle by a differential bridge 22. This receiving shaft 18 is also connected, here by means of a band 24 closed on itself, like a belt or a chain, to the rotor 26 of a driving / generating machine 28, such as an electric, hydraulic or pneumatic, which is reported and fixed on the housing of the speed variation device.
L'inconvénient que présente une telle disposition du moteur électrique sur le carter est de ne pas pouvoir adapter l'encombrement de l'ensemble formé par le dispositif de variation de vitesse et le moteur électrique à l'espace disponible pour implanter cet ensemble. The disadvantage of such an arrangement of the electric motor on the housing is not to adapt the size of the assembly formed by the speed variation device and the electric motor to the space available to implement this set.
De ce fait, il faut modifier la fixation du moteur électrique sur le carter pour chaque type d'implantation, ce qui entraîne des coûts non négligeables et une complexité d'élaboration en multipliant le nombre de pièces en fonction de l'implantation désirée.  Therefore, it is necessary to change the attachment of the electric motor on the housing for each type of implantation, which entails significant costs and complexity of development by multiplying the number of parts depending on the desired location.
La présente invention se propose de remédier aux inconvénients mentionnés ci-dessus grâce à dispositif de fixation du moteur électrique de conception simple qui peut être utilisé pour une majorité d'implantations. A cet effet, la présente invention concerne un dispositif de variation de vitesse d'un groupe motopropulseur pour l'entraînement d'un véhicule automobile de type hybride, comprenant un carter logeant un arbre moteur et un arbre récepteur, ledit arbre récepteur étant reliée cinématiquement au rotor d'une machine motrice/génératrice, caractérisé en ce que la machine est portée par une platine fixée par une embase sur le carter et munie d'un réglage de l'entraxe entre l'arbre récepteur et le rotor. The present invention proposes to overcome the drawbacks mentioned above by means of electric motor fixing device of simple design that can be used for a majority of implantations. To this end, the present invention relates to a speed variation device of a powertrain for driving a hybrid type of motor vehicle, comprising a housing housing a motor shaft and a receiving shaft, said receiver shaft being connected kinematically. the rotor of a driving / generating machine, characterized in that the machine is carried by a plate fixed by a base on the housing and provided with a setting of the distance between the receiver shaft and the rotor.
La platine peut comporter des lumières oblongues pour régler la position du rotor de la machine par rapport à l'arbre récepteur. The plate may comprise oblong slots to adjust the position of the rotor of the machine relative to the receiving shaft.
La platine peut comporter deux parties télescopiques pour régler la position du rotor de la machine par rapport à l'arbre récepteur. La platine peut comporter un évidement coopérant avec une protubérance portée par la machine en étant excentrée par rapport l'axe du rotor. The plate can have two telescopic parts to adjust the position of the rotor of the machine relative to the receiving shaft. The plate may comprise a recess cooperating with a protrusion carried by the machine being eccentric with respect to the axis of the rotor.
La protubérance peut porter de cannelures sur sa périphérie pour coopérer avec des cannelures complémentaires de l'évidement. The protuberance may carry grooves on its periphery to cooperate with complementary grooves of the recess.
La protubérance peut porter des crans sur son extrémité libre pour coopérer avec des crans complémentaires de l'évidement. La protubérance peut porter un passage de fixation. The protuberance may carry notches on its free end to cooperate with complementary notches of the recess. The protuberance may carry a fixing passage.

Sur les figures 1 et 2 de l'art antérieur, le groupe motopropulseur illustré comprend un moteur thermique 10, notamment un moteur à combustion interne, avec un arbre moteur 14, ici issu du vilebrequin 12 de ce moteur, un dispositif de variation de vitesse 1 6, une machine motrice/génératrice 28 et un essieu moteur 20 qui permet d'entraîner les roues motrices du véhicule, avantageusement par l'intermédiaire d'un pont différentiel 22. Le dispositif de variation de vitesse 1 6 peut être de tout type, comme une boîte de vitesse conventionnelle avec un arbre moteur, un arbre récepteur, des pignons portés par ces arbres et des baladeurs. In FIGS. 1 and 2 of the prior art, the illustrated powertrain comprises a heat engine 10, in particular an internal combustion engine, with a drive shaft 14, here coming from the crankshaft 12 of this engine, a speed variation device. 1 6, a driving machine / generator 28 and a drive axle 20 which can drive the drive wheels of the vehicle, preferably via a differential bridge 22. The speed variation device 1 6 can be of any type , like a conventional gearbox with a motor shaft, a receiver shaft, pinions carried by these trees and walkmans.
Dans la suite de la description, il est fait mention, uniquement à titre d'exemple, d'un autre type de dispositif de variation de vitesse comportant un arbre moteur, un arbre récepteur et un double train épicycloïdal, comme cela est mieux décrit dans la demande brevet WO 2012/007661 du demandeur. In the remainder of the description, mention is made, by way of example only, of another type of speed variation device comprising a driving shaft, a receiving shaft and a double epicyclic gear train, as is better described in FIG. patent application WO 2012/007661 of the applicant.
Plus précisément illustré à la figure 3, ce dispositif de variation de vitesse comprend un train épicycloïdal principal 30, baptisé train épicycloïdal de moteur thermique, avec deux accouplements à commande contrôlée 32, 34 et deux accouplements unidirectionnels automatiques, comme des roues libres 36, 38.  More precisely illustrated in FIG. 3, this speed variation device comprises a main epicyclic gear train 30, called the epicyclic heat engine gear train, with two controlled-control couplings 32, 34 and two automatic unidirectional couplings, such as freewheels 36, 38. .
Le train épicycloïdal de moteur comprend un planétaire 40 monté fixement sur un arbre creux 42, dit arbre de planétaire, venant coiffer l'arbre 14 du moteur et s'appuyant sur la roue libre 38 placée sur le carter 44 du dispositif de variation de vitesse, une couronne 46 reliée à un arbre creux 48, dit arbre de couronne, venant entourer l'arbre creux 42 du planétaire. Cette couronne est reliée extérieurement au carter du dispositif de variation de vitesse par la roue libre 36. Ce train épicycloïdal de moteur comprend également un porte-satellites 50 avec des satellites 52 engrenant avec la couronne et le planétaire et relié à un palier tubulaire 54, dit palier de porte-satellites, qui vient entourer l'arbre de planétaire 42. The epicyclic motor train comprises a sun gear 40 fixedly mounted on a hollow shaft 42, said sun gear shaft, which cap the motor shaft 14 and resting on the free wheel 38 placed on the housing 44 of the speed variation device , a ring 46 connected to a hollow shaft 48, said crown shaft, surrounding the hollow shaft 42 of the sun gear. This ring is connected externally to the casing of the speed variation device by the freewheel 36. This epicyclic motor train also comprises a planet carrier 50 with satellites 52 meshing with the ring gear and the sun gear and connected to a tubular bearing 54, said bearing planet carrier, which surrounds the planet shaft 42.
Dans l'exemple de la figure 1 , les extrémités libres des arbres creux du planétaire et de la couronne portent chacune un accouplement à commande contrôlée 32 et 34, de préférence un embrayage à friction permettant de relier l'arbre moteur 14 à l'un et/ou l'autre des arbres creux.  In the example of FIG. 1, the free ends of the hollow shafts of the sun gear and the ring each carry a controlled-control coupling 32 and 34, preferably a friction clutch for connecting the drive shaft 14 to one and / or the other hollow trees.
Par cela, T'arbre 14, et l'arbre creux de planétaire 42 et/ou l'arbre creux de couronne 48 forme(nt) l'arbre moteur du dispositif de variation de vitesse 1 6.  By this, the shaft 14, and the hollow sun shaft 42 and / or the hollow crown shaft 48 form (s) the motor shaft of the speed variation device 1 6.
Comme mieux illustré sur la figure 1 , le porte-satellites 50 comprend un anneau denté 56 qui coopère avec un bandeau denté 58 porté par un train épicycloïdal additionnel 60, dénommé dans la suite de la description train épicycloïdal de machine. As best illustrated in Figure 1, the planet carrier 50 comprises a toothed ring 56 which cooperates with a toothed strip 58 carried by an additional epicyclic train 60, hereinafter referred to as the machine epicyclic train description.
Cet autre train épicycloïdal 60 est placé sur un arbre fixe 62 relié au carter 44 en étant sensiblement parallèle aux arbres creux du train épicycloïdal de moteur. Ce train épicycloïdal de machine comprend une couronne 64 comprenant le bandeau dentée 58, un planétaire 66 et un porte-satellites 68 avec des satellites 70 engrenant avec la couronne et le planétaire. Comme mieux visible sur la figure 1 , la couronne, le porte-satellites et le planétaire sont concentriques à l'arbre 62.  This other epicyclic gear train 60 is placed on a fixed shaft 62 connected to the housing 44 being substantially parallel to the hollow shafts of the epicyclic motor train. This epicyclic machine train comprises a ring 64 comprising the toothed strip 58, a sun gear 66 and a planet carrier 68 with satellites 70 meshing with the ring gear and the sun gear. As best seen in Figure 1, the ring gear, the planet carrier and the sun gear are concentric with the shaft 62.
Le porte-satellites est porté par un arbre ceux 72 qui porte également une roue dentée 74 qui coopère avec une autre roue dentée 76 liée à l'essieu moteur 20. Cet ensemble des deux roues dentées forme ainsi une voie de transmission de mouvement entre le train épicycloïdal de machine 60 et l'essieu 20.  The planet carrier is carried by a shaft 72 which also carries a toothed wheel 74 which cooperates with another gear wheel 76 connected to the driving axle 20. This set of two toothed wheels thus forms a motion transmission path between the Machine epicyclic train 60 and axle 20.
Le planétaire 66 est relié à un arbre tubulaire 78, dit arbre de planétaire additionnel, qui vient entourer l'arbre fixe 62. L'extrémité libre de l'arbre tubulaire 78 porte fixement une roue 80, ici une roue dentée, qui coopère avec une bande refermée sur elle-même, comme une chaîne 24 qui coopère avec une roue 84, ici une roue dentée, portée par le rotor 26 de la machine motrice/génératrice 28.  The sun gear 66 is connected to a tubular shaft 78, said additional sun gear shaft, which surrounds the fixed shaft 62. The free end of the tubular shaft 78 fixedly supports a wheel 80, here a toothed wheel, which cooperates with a band closed on itself, like a chain 24 which cooperates with a wheel 84, here a toothed wheel, carried by the rotor 26 of the driving / generating machine 28.
Le train épicycloïdal de machine 60 porte également un accouplement à commande contrôlée 90, avantageusement un actionneur à griffe à deux positions actives et une position neutre, permettant de relier sa couronne 64, soit au carter 44 du dispositif de variation de vitesse, soit au porte-satellites 68 avec son arbre creux 72 qui forme alors l'arbre récepteur du dispositif de variation de vitesse. Ainsi, l'arbre récepteur du dispositif de variation de vitesse est formé soit par l'arbre tubulaire 78, soit par l'arbre creux 72, soit par l'association des deux arbres creux. The machine epicyclic train 60 also carries a controlled-control coupling 90, advantageously a claw actuator with two active positions and a neutral position, making it possible to connect its crown 64 either to the casing 44 of the speed variation device or to the door -satellites 68 with its hollow shaft 72 which then forms the receiving shaft of the speed variation device. Thus, the receiving shaft of the speed variation device is formed either by the tubular shaft 78, or by the hollow shaft 72, or by the combination of the two hollow shafts.
Dans le cas où la machine 28 est utilisée en tant que machine motrice, l'arbre tubulaire 78 devient un arbre moteur et reçoit le mouvement de rotation de cette machine pour le transmettre à l'essieu moteur via la voie de transmission de mouvement des roues 74 et 76.  In the case where the machine 28 is used as a prime mover, the tubular shaft 78 becomes a driving shaft and receives the rotational movement of this machine for transmission to the driving axle via the wheel motion transmission path. 74 and 76.
Pour des raisons de simplification dans la suite de la description, cet arbre récepteur/moteur 78 sera uniquement dénommé arbre récepteur. For reasons of simplification in the following description, this receiver / motor shaft 78 will only be called receiver shaft.
Comme mieux visible sur la figure 3, la machine électrique 28 est portée de manière fixe par une extrémité haute 92 d'une platine 94 dont l'extrémité basse 96 est fixée sur le carter 44 par tous moyens, comme par vissage. As best seen in Figure 3, the electric machine 28 is fixedly supported by an upper end 92 of a plate 94 whose lower end 96 is fixed on the housing 44 by any means, such as by screwing.
Sur le premier exemple de réalisation des figures 4A et 4B, la platine 94, ici verticale, de forme allongée comporte à son extrémité basse 96, une embase 100, ici circulaire, comprenant un alésage 102 pour le passage de la roue dentée 80 portée par l'arbre creux 78 de planétaire avec un diamètre plus grand que le diamètre extérieur de la roue. Cette embase est également munie d'une multiplicité de trous de fixation 104 régulièrement repartis circonférentiellement autour de l'alésage 102 pour la fixation sur le carter 44. In the first embodiment of FIGS. 4A and 4B, the plate 94, here vertical, of elongate shape has at its lower end 96, a base 100, here circular, comprising a bore 102 for the passage of the toothed wheel 80 carried by the sun shaft 78 with a larger diameter than the outer diameter of the wheel. This base is also provided with a multiplicity of fixing holes 104 regularly distributed circumferentially around the bore 102 for attachment to the casing 44.
A l'extrémité haute 92, la platine comporte des lumières oblongues de fixation 106 et de déplacement 108.  At the high end 92, the plate has oblong fixing and displacement slots 108.
Les lumières de fixation 106 sont réalisées verticalement et sont disposées sensiblement symétriquement par rapport à l'axe général vertical XX de la platine alors que la lumière oblongue de déplacement 108, également verticale, est placée dans l'axe de la platine entre les lumières de fixation. Cette lumière de déplacement présente une dimension en largeur plus grande que le rotor 26 de la machine 28 et une dimension en hauteur correspond sensiblement à celle des lumières de fixation.  The fixing holes 106 are made vertically and are arranged substantially symmetrically with respect to the vertical general axis XX of the plate while the oblong displacement light 108, also vertical, is placed in the axis of the plate between the lights of fixation. This displacement light has a greater width dimension than the rotor 26 of the machine 28 and a height dimension corresponds substantially to that of the fixing lights.
La platine est tout d'abord placée verticalement sur le carter 44 de façon à ce que la roue 80 de l'arbre 78 traverse l'alésage 102 puis cette platine est fixée par tous moyens connus sur le carter, comme par des vis traversant les trous 104 et coopérant avec des taraudages (non représentés) prévus sur le carter. The plate is first placed vertically on the housing 44 so that the wheel 80 of the shaft 78 passes through the bore 102 and this plate is fixed by all known means on the housing, such as by screws through the holes 104 and cooperating with threads (not shown) provided on the housing.
Une fois cette fixation réalisée, la machine 28 est présentée en regard de l'extrémité haute de la platine de façon à ce que la lumière de déplacement 108 et le passage circulaire central 109 de son flasque 1 10 soient traversés par le rotor 26 de la machine. Une fois que la position souhaitée du rotor de la machine 28 par rapport à l'axe de l'arbre récepteur 78 est atteinte (entraxe E), les lumières de fixation 106 sont alors traversées par des moyens de fixation, comme des vis (non représentés) et la machine est immobilisée sur la platine par le serrage des vis sur le flasque 1 10.  Once this fixation is made, the machine 28 is presented facing the upper end of the plate so that the displacement light 108 and the central circular passage 109 of its flange 1 10 are traversed by the rotor 26 of the machine. Once the desired position of the rotor of the machine 28 relative to the axis of the receiving shaft 78 is reached (center distance E), the fixing holes 106 are then traversed by fastening means, such as screws (no shown) and the machine is immobilized on the plate by tightening the screws on the flange 1 10.
Bien entendu, au préalable de ce serrage, la roue dentée 84 est placé sur le rotor 26 et la chaîne est mise en place sur les roues dentées 80 et 84 pour assurer, après fixation, la transmission du mouvement de rotation entre la machine et l'arbre 78. Of course, prior to this clamping, the toothed wheel 84 is placed on the rotor 26 and the chain is put in place on the gears 80 and 84 to ensure, after fixation, the transmission of the rotational movement between the machine and the machine. tree 78.
Ce premier exemple de réalisation permet ainsi de régler d'une manière simple et sûre l'entraxe E entre le rotor 26 de la machine 28 et l'axe de l'arbre 78 (symbolisé sur la figure par deux traits d'axes orthogonaux) et cela selon une multitude d'entraxes possibles dépendant de la longueur des lumières.  This first embodiment thus makes it possible to adjust in a simple and safe way the distance between the rotor 26 of the machine 28 and the axis of the shaft 78 (symbolized in the figure by two lines of orthogonal axes) and this in a multitude of possible distances depending on the length of the lights.
Le deuxième exemple de réalisation des figures 5A et 5B permet également de régler de manière simple et sûre l'entraxe entre le rotor de la machine et l'arbre 78. The second embodiment of FIGS. 5A and 5B also makes it possible to simply and securely adjust the distance between the rotor of the machine and the shaft 78.
Cet exemple se distingue du précédent par le fait que, après fixation de la platine sur le carter comme précédemment décrit, la machine 28 est placée et fixée sur l'extrémité haute de la platine par la fixation avec le flasque 1 10.  This example differs from the previous in that, after fixing the plate on the housing as previously described, the machine 28 is placed and fixed on the upper end of the plate by fixing with the flange 1 10.
Pour pouvoir assurer le réglage de l'entraxe E entre le rotor 26 de la machine et l'arbre 78, la platine est conçue en deux parties télescopiques 94a et 94b et permet une translation de l'extrémité haute par rapport à l'extrémité basse fixé sur le carter.  In order to be able to adjust the center distance E between the rotor 26 of the machine and the shaft 78, the plate is designed in two telescopic parts 94a and 94b and allows translation of the upper end relative to the lower end. fixed on the housing.
Un fois atteint l'entraxe souhaité et après mise en place de la chaîne, les deux parties télescopiques sont fixées l'une avec l'autre comme par un système de lumières oblongues portées par l'une des parties et de vis portées par l'autre partie (non représenté). L'exemple de réalisation de la figure 6 concerne la possibilité de régler l'entraxe E entre le rotor 26 de la machine et l'arbre 78 par un système d'excentrique 1 12. Pour cela, l'extrémité haute 92 de la platine 94 comporte un évidement borgne 1 14, ici circulaire, et le flasque 1 10 porte une protubérance 1 1 6, ici cylindrique, qui est placée de manière excentrée (distance D) par rapport au passage circulaire 109 du flasque 1 10 dans lequel est placé le rotor 26 de la machine 28. Once reached the desired distance and after installation of the chain, the two telescopic parts are fixed with each other as a system of oblong lights carried by one of the parts and screws carried by the other party (not shown). The embodiment of Figure 6 relates to the possibility of adjusting the distance between E the rotor 26 of the machine and the shaft 78 by an eccentric system 1 12. For this, the high end 92 of the plate 94 has a blind recess 1 14, here circular, and the flange 1 10 carries a protrusion 1 1 6, here cylindrical, which is placed eccentrically (distance D) relative to the circular passage 109 of the flange 1 10 in which is placed the rotor 26 of the machine 28.
De plus, l'extrémité haute 92 de la platine 94 porte une lumière oblongue courbe 1 18 (symbolisée par un trait d'axe) pour le passage et le déplacement du rotor au travers de cette extrémité haute.  In addition, the upper end 92 of the plate 94 carries a curved oblong slot 1 18 (symbolized by a center line) for the passage and movement of the rotor through this high end.
Lors de l'assemblage, la protubérance est mise en place dans l'évidement puis, le flasque 1 10 est amené à pivoter autour de l'axe de l'ensemble protubérance/évidement jusqu'à obtenir l'entraxe souhaité. Une fois la position atteinte par le flasque pour cet entraxe, la machine 28 est présentée en regard de l'extrémité haute de la platine de façon à ce que la lumière oblongue courbe 1 18 et le passage circulaire 109 du flasque 1 10 soient traversées par le rotor 26 de la machine.  During assembly, the protrusion is placed in the recess and then the flange 1 10 is pivoted about the axis of the protrusion / recess assembly until the desired distance between centers. Once the position reached by the flange for this distance, the machine 28 is presented opposite the upper end of the plate so that the oblong curved light 1 18 and the circular passage 109 of the flange 1 10 are traversed by the rotor 26 of the machine.
Par la suite, la machine 28 est fixée sur la platine 94 par des vis qui coopèrent avec des trous 120 prévus sur le flasque.  Subsequently, the machine 28 is fixed on the plate 94 by screws which cooperate with holes 120 provided on the flange.
L'exemple de réalisation la figure 7 et la coupe de la figure 8 selon la ligne 8- 8 de la figure 7 illustre une variante du flasque 1 10 avec sa protubérance 1 1 6. The embodiment of Figure 7 and the section of Figure 8 along the line 8-8 of Figure 7 illustrates a variant of the flange 1 10 with its protuberance 1 1 6.
Dans cette variante, la protubérance présente sur sa périphérie circulaire extérieure des cannelures 122 et un passage 124 de fixation.  In this variant, the protuberance has on its outer circular periphery grooves 122 and a passage 124 fixing.
L'évidement 1 14 présente également des cannelures (non représentées) de forme et de disposition complémentaires à celle de la protubérance ainsi qu'un alésage de fixation (également non représenté), comme un taraudage, en concordance avec le passage de fixation 124.  The recess 1 14 also has grooves (not shown) of complementary shape and disposition to that of the protuberance and a fixing bore (also not shown), such as a tapping, in accordance with the fixing passage 124.
Ainsi pour régler l'entraxe, il suffit d'indexer la protubérance 1 1 6 dans l'évidement 1 14 en faisant coïncider les cannelures de la protubérance avec celle de l'évidement pour la position recherchée puis d'immobiliser la protubérance dans l'évidement en utilisant tous moyens connus, comme une vis qui traverse le passage 124 pour coopérer avec l'alésage de fixation. Thus to adjust the distance, it is sufficient to index the protuberance 1 1 6 in the recess 1 14 by aligning the grooves of the protuberance with that of the recess for the desired position and to immobilize the protuberance in the recess using any known means, such as a screw which passes through the passage 124 to cooperate with the fixing bore.
L'autre variante de la figure 6, telle qu'illustrée par la figure 9 et la coupe de la figure 10 selon la ligne 10-10 de la figure 9, se démarque de la précédente variante par le fait que l'extrémité libre 126 de la protubérance 1 1 6 porte des crans 128, ici des crans radiaux, qui sont prévus pour coopérer avec des crans complémentaires (non représentés) prévus dans le fond de l'évidement borgne 1 14. The other variant of FIG. 6, as illustrated by FIG. 9 and the section of FIG. 10 along line 10-10 of FIG. 9, differs from the previous variant in that the free end 126 the protrusion 1 1 6 carries notches 128, here radial notches, which are provided to cooperate with complementary notches (not shown) provided in the bottom of the blind recess 1 14.
Comme pour la variante des figures 7 et 8, la mise en place de la protubérance dans l'évidement est réalisée par indexage des deux éléments et par vissage de l'un des éléments sur l'autre.  As for the variant of Figures 7 and 8, the introduction of the protuberance in the recess is performed by indexing the two elements and by screwing one of the elements on the other.
Il est à noter que les exemples de réalisations des figures 6 à 10 permettent non seulement de régler l'entraxe entre l'arbre 78 et le rotor de la machine 28 mais aussi la position angulaire a entre l'axe passant par les axes du rotor 26 de l'arbre 78 et un axe vertical. It should be noted that the exemplary embodiments of FIGS. 6 to 10 make it possible not only to adjust the distance between the shaft 78 and the rotor of the machine 28 but also the angular position a between the axis passing through the axes of the rotor. 26 of the shaft 78 and a vertical axis.
L'exemple illustré sur la figure 1 1 permet de régler l'entraxe entre l'arbre 78 et le rotor de la machine 28 grâce au pas angulaire β des trous de fixation 104 prévus sur l'embase 100 de l'extrémité basse 96 de la platine et des taraudages prévus sur le carter. The example illustrated in FIG. 11 makes it possible to adjust the distance between the shaft 78 and the rotor of the machine 28 thanks to the angular pitch β of the fixing holes 104 provided on the base 100 of the lower end 96 of FIG. the plate and tappings provided on the housing.
Ainsi pour pouvoir régler l'entraxe E, il suffit, à partir de la position verticale de la platine montrée à la figure 1 1 , de faire pivoter cette platine autour de l'axe de l'arbre 78 d'un ou plusieurs pas β puis, une fois arrivé à la position souhaitée P1 avec une nouvelle concordance des trous de fixations 104 avec les taraudages du carter, à fixer la platine 94 sur le carter par vissage.  Thus, in order to adjust the center distance E, it is sufficient, from the vertical position of the plate shown in FIG. 1 1, to rotate this plate about the axis of the shaft 78 by one or more steps β then, once arrived at the desired position P1 with a new match of the fixing holes 104 with the threads of the housing, to fix the plate 94 on the housing by screwing.
La figure 12 illustre un autre exemple de réalisation pour lequel les trous de fixation de l'embase 100 de l'extrémité basse 96 sont des trous oblongues 130 d'étendue angulaire δ, ce qui permet de faire pivoter la platine d'un angle qui correspond à l'entendue angulaire de ces trous oblongues. FIG. 12 illustrates another exemplary embodiment for which the holes for fixing the base 100 of the low end 96 are oblong holes 130 of angular extent δ, which makes it possible to pivot the plate by an angle which corresponds to the angular heard of these oblong holes.
Bien entendu et cela sans sortir du cadre de l'invention, il peut être prévu de combiner cet exemple de réalisation avec celui de la figure 1 1 en faisant pivoter la platine 94 d'un pas angulaire β puis d'affiner le réglage de l'entraxe en faisant pivoter cette platine selon l'étendue angulaire δ des trous oblongues. Of course, and without departing from the scope of the invention, it may be provided to combine this embodiment with that of FIG. 1, by rotating the platinum 94 angular step β and then refine the setting of the center distance by rotating the plate according to the angular extent δ oblong holes.
La figure 13 illustre un autre exemple de réalisation, qui est issu de la figure 12, pour lequel aux trous oblongues 130 de l'embase 100 de la partie basse 96 sont associés des encoches 132, ici des encoches radiales, aptes à coopérer avec des encoches complémentaires prévues sur le carter 44. FIG. 13 illustrates another exemplary embodiment, which comes from FIG. 12, for which the oblong holes 130 of the base 100 of the lower part 96 are associated with notches 132, here radial notches, able to cooperate with additional notches provided on the housing 44.
Les exemples de réalisation des figures 1 1 à 13 permettent ainsi de régler l'entraxe entre l'arbre 78 et le rotor de la machine 28 mais aussi la position angulaire entre ce rotor et l'arbre 78. The exemplary embodiments of FIGS. 1 to 13 thus make it possible to adjust the spacing between the shaft 78 and the rotor of the machine 28 but also the angular position between this rotor and the shaft 78.
