Description

La présente invention concerne un dispositif pour l'accouplement d'une machine rotative à un arbre d'entrainement.The present invention relates to a device for coupling a rotary machine to a drive shaft.

Quoique non exclusivement, elle est particulièrement appropriée au montage direct d'une pompe ou d'un moteur hydraulique sur la prise de force d'un tracteur et elle sera plus spécialement décrite cl-aprs en rapport avec cette application.Although not exclusively, it is particularly suitable for the direct mounting of a hydraulic pump or motor on the PTO of a tractor and it will be more particularly described below in connection with this application.

On sait qu'il est usuel d'utiliser la prise de force d'un tracteur pour entrainer une pluralité de machines rotatives, par exemple une pompe ou un moteur hydraulique, et, à cet effet, on prévoit des moyens pour solidariser en rotation l'arbre d'entrainement de ladite prise de force et l'arbre de ladite machine rotative. De plus, on prévoit des moyens de liaison entre le bâti par rapport auquel tourne ledit arbre d'entrainement, c'est-à-dire le châssis du tracteur, et le stator de ladite machine rotative, à la double fin de faire supporter ladite machine rotative par le châssis du tracteur et de bloquer la tendance à la rotation du stator de la machine rotative, pendant l'entraînement de l'arbre de celle-ci par la prise de force.We know that it is usual to use the PTO of a tractor to drive a plurality of rotary machines, for example a pump or a hydraulic motor, and, for this purpose, means are provided for securing in rotation the drive shaft of said PTO and the shaft of said rotary machine. In addition, connection means are provided between the frame with respect to which said drive shaft rotates, that is to say the chassis of the tractor, and the stator of said rotary machine, for the dual purpose of making said support rotary machine by the chassis of the tractor and to block the tendency of the stator of the rotary machine to rotate, during the drive of the shaft thereof by the PTO.

Généralement, ces moyens de liaison comportent une chaîne accrochée d'un côté au stator de la machine rotative et de l'autre au châssis du tracteur. Or, l'expérience a montré que les efforts exercés par la machine rotative sur la chaine empèchant l'entraînement en rotation de son stator étaient très importants et qu'il en résultait souvent la rupture de ladite chaîne.Generally, these connecting means comprise a chain attached on one side to the stator of the rotary machine and on the other to the chassis of the tractor. However, experience has shown that the forces exerted by the rotary machine on the chain preventing the rotational drive of its stator were very high and that the chain often broke.

La présente invention a pour objet un tel dispositif d'accouplement permettant d'éviter cet inconvénient. The present invention relates to such a coupling device making it possible to avoid this drawback.

Il est alors avantageux que les extremités supérieures desdites barres soient solidaires, éventuellement par l'intermédiaire de ladite traverse, d'une pièce de liaison audit bâti et que le point d'ancrage supérieur desdits moyens de suspension se trouve sur ladite pièce de liaison.It is then advantageous for the upper ends of said bars to be secured, possibly via said cross member, to a connecting piece to said frame and for the upper anchoring point of said suspension means to be located on said connecting piece.

On obtient ainsi une unité d'accouplement comportant deux barres anti-couple, une pièce de liaison et des moyens de suspension.A coupling unit is thus obtained comprising two anti-torque bars, a connecting piece and suspension means.

Lorsque, de façon connue sur les tracteurs, ledit bâti comporte deux plaques verticales parallèles pourvues de trous en corespondance horizontale, il est avantageux que ladite pièce de liaison soit un manchon susceptible d'être traversé par une broche traversant également lesdites plaques.When, in a known manner on tractors, said frame comprises two parallel vertical plates provided with holes in horizontal correspondence, it is advantageous that said connecting piece is a sleeve capable of being crossed by a pin also passing through said plates.

On obtient ainsi une possibilité de reglage, pour adapter ledit dispositif à différents matériels. Pour augmenter cette possibilité, il est également avantageux que lesdites barres comportent également une pluralité de trous pour la liaison au stator de la machine rotative et/ou à la traverse.There is thus obtained a possibility of adjustment, to adapt said device to different materials. To increase this possibility, it is also advantageous that said bars also include a plurality of holes for connection to the stator of the rotary machine and / or to the cross-member.

Pour tenir compte du décalage vertical possible entre la pièce de liaison et la machine rotative, dû aux moyens de solidarisation en rotation, il est avantageux de prévoir un liaison mécanique entre ladite pièce de liaison et les extrêmités supérieures des barres. Pour pouvoir s'adapter a maximum de matériel possible, cette liaison peut être règlable en longueur.To take account of the possible vertical offset between the connecting piece and the rotary machine, due to the means for securing in rotation, it is advantageous to provide a mechanical connection between said connecting piece and the upper ends of the bars. To be able to adapt to the maximum possible material, this link can be adjustable in length.

Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. Sur ces figures, des références identiques désignent des éléments semblables. The figures of the appended drawing will make it clear how the invention can be implemented. In these figures, identical references designate similar elements.

A cette fin, selon l'invention, le dispositif pour l'accouplement d'une machine rotative à un arbre d'entralnement, comportant des moyens pour solidariser en rotation ledit arbre d'entraînement et l'arbre de ladite machine rotative, ainsi que des moyens de support mécanique disposés entre le bâti par rapport auquel tourne ledit arbre d'entrainement et le stator de ladite machine rotative1 afin de supporter celle-ci et d'empêcher l'entraînement en rotation dudit stator, est remarquable en ce que lesdits moyens de support comportent deux barres reliées, à leur partie inférieure, en deux points verticalement symétriques du stator de ladite machine rotative et, à leur partie supérieure, entre elles et audit bâti.To this end, according to the invention, the device for coupling a rotary machine to a centering shaft, comprising means for securing in rotation said drive shaft and the shaft of said rotary machine, as well as mechanical support means disposed between the frame with respect to which said drive shaft rotates and the stator of said rotary machine1 in order to support the latter and prevent the rotational drive of said stator, is remarkable in that said means support comprises two bars connected, at their lower part, at two vertically symmetrical points of the stator of said rotary machine and, at their upper part, between them and to said frame.

Ainsi, l'une desdites barres travaille en traction et l'autre en compression, et, à leur partie supérieure, les efforts exercés sur l'une sont équilibrés par les efforts exercés sur l'autre. Par suite, on obtient un système anti-couple équilibré, résistant particulièrement bien aux efforts importants résultant du blocage en rotation du stator.Thus, one of said bars works in tension and the other in compression, and, at their upper part, the forces exerted on one are balanced by the forces exerted on the other. As a result, a balanced anti-torque system is obtained, which is particularly resistant to the large forces resulting from the stator being blocked in rotation.

De préférence, lesdites barres sont parallèles entre elles et reliées, à leur partie inférieure, en deux points diamètralement opposés du stator de ladite machine rotative et, à leur partie supérieure, à une traverse reliée audit bâti. Dans ce cas, l'équilibrage des efforts est réalisé par l'intermédiaire de ladite traverse.Preferably, said bars are mutually parallel and connected, at their lower part, at two diametrically opposite points of the stator of said rotary machine and, at their upper part, to a crosspiece connected to said frame. In this case, the balancing of the forces is carried out by means of said crosspiece.

Dans un mode de réalisation avantageux, lesdits moyens de liaison comportent de plus des moyens de suspension, tels qu'un ressort par exemple, pour faire supporter la plus grande partie du poids de ladite machine rotative audit bâti, de sorte que lesdites barres ne supportent pratiquement que les efforts de couple exercés par le stator. In an advantageous embodiment, said connecting means further comprises suspension means, such as a spring for example, to support most of the weight of said rotary machine on said frame, so that said bars do not support practically only the torque forces exerted by the stator.

La figure 1 est une vue en perspective d'un dispositif selon l'invention.Figure 1 is a perspective view of a device according to the invention.

La figure 2 est une vue de dessus éclatée d'un dispositif selon l'invention.Figure 2 is an exploded top view of a device according to the invention.

Les dispositifs selon l'invention, montrés par les figures 1 et 2, sont destinés à accoupler une machine rotative 1, par exemple une pompe ou un moteur hydraulique, à l'arbre cannelé 2 de la prise de force 3 d'un tracteur, dont seule la partie arrière 4 est représentée schématiquement. Ces dispositifs comportent des moyens 5 pour solidariser en rotation l'arbre 2 de la prise de force 3 et 11 arbre 6 de la machine rotative 1.The devices according to the invention, shown in FIGS. 1 and 2, are intended to couple a rotary machine 1, for example a pump or a hydraulic motor, to the splined shaft 2 of the PTO 3 of a tractor, of which only the rear part 4 is shown diagrammatically. These devices include means 5 for securing in rotation the shaft 2 of the power take-off 3 and 11 shaft 6 of the rotary machine 1.

De façon connue, à l'arrière 4 du tracteur sont prévues deux plaques verticales et parallèles 7 et 8 respectivement, pourvues d'une pluralité de trous 9 et 10, échelonnés verticalement et deux à deux en correspondance horizontale.In known manner, at the rear 4 of the tractor are provided two vertical and parallel plates 7 and 8 respectively, provided with a plurality of holes 9 and 10, staggered vertically and two by two in horizontal correspondence.

Selon l'invention, pour supporter la machine rotative 1 et empecher son stator de tourner sous l'effet de la rotation de son arbre 6, on prévoit deux barres 11 et 12, une traverse 13, un manchon 14, une liaison 15 entre la traverse 13 et le manchon 14, une broche 16 et un ressort 17.According to the invention, to support the rotary machine 1 and prevent its stator from rotating under the effect of the rotation of its shaft 6, two bars 11 and 12 are provided, a cross member 13, a sleeve 14, a connection 15 between the cross member 13 and the sleeve 14, a pin 16 and a spring 17.

Les deux barres 11 et 12 sont disposées verticalement et sont pourvues d'une pluralité de trous 18 et 19, échelonnés verticalement et traversés par des boulons 20,21 cooperant avec des écrous et éventuellement des contre-ecrous 22,23 pour solidariser la partie inférieure desdites barres avec deux points diamétralement opposés d'une bride 24 du stator de la machine rotative 1. D'autres boulons 25,26 traversent les trous 18 et 19 et coopèrent avec des écrous (et éventuellement des contre-écrous) 27,28 pour solidariser la partie supérieure desdites barres 11 et 12 des extrémité3 horizontalement opposées de la traverse 13. La partie médiane de ladite traverse 13 est solidaire du manchon 14 par une liaison 15, éventuellement réglable en longueur (voir la figure 2).The two bars 11 and 12 are arranged vertically and are provided with a plurality of holes 18 and 19, staggered vertically and traversed by bolts 20,21 cooperating with nuts and possibly locknuts 22,23 to secure the lower part said bars with two diametrically opposite points of a flange 24 of the stator of the rotary machine 1. Other bolts 25,26 pass through the holes 18 and 19 and cooperate with nuts (and possibly locknuts) 27,28 for securing the upper part of said bars 11 and 12 of the horizontally opposite end3 of the cross member 13. The middle part of said cross member 13 is secured to the sleeve 14 by a link 15, possibly adjustable in length (see FIG. 2).

Le manchon 14 est disposé entre les plaques 7 et 8 et est rendu solidaire de celles-ci par la broche 16 qui le traverse longitudinalement en prenant appui sur deux trous 9,10 en regard. Une goupille 29 traversant un trou 30 de la broche 16 rend celle-ci prisonnière desdites plaques 7 et 8.The sleeve 14 is disposed between the plates 7 and 8 and is made integral with the latter by the pin 16 which passes through it longitudinally by resting on two opposite holes 9,10. A pin 29 passing through a hole 30 in the pin 16 makes the latter captive of said plates 7 and 8.

Le ressort 17 s'accroche par ses extrêmités, à des anneaux 31 et 32, respectivement solidaires du stator de la machine rotative 1 et du manchon 14.The spring 17 is hooked at its ends to rings 31 and 32, respectively integral with the stator of the rotary machine 1 and the sleeve 14.

On voit que, grâce au dispositif selon l'invention, la machine 1 est supportée par le ressort 17 et empechée de tourner par les barres 11 et 12, la traverse 13, la liaison 15, le manchon 14 et la broche 16. L'effet anticouple exercé par ledit dispositif est équilibré. Grâce aux trous 9,10,18,19 et éventuellement à la liaison réglable 15, de nombreuses possibilités de réglage sont possibles pour s'adapter à ia machine 1 et à son arbre 6. Eventuellement, pour rattraper des défauts d'alignement, on peut prévoir des jeux dans les liaisons au moyen des boulons 20,21,25 et 26. We see that, thanks to the device according to the invention, the machine 1 is supported by the spring 17 and prevented from rotating by the bars 11 and 12, the cross member 13, the connection 15, the sleeve 14 and the spindle 16. The anti-torque effect exerted by said device is balanced. Thanks to the holes 9, 10, 18, 19 and possibly to the adjustable link 15, numerous adjustment possibilities are possible to adapt to the machine 1 and to its shaft 6. Optionally, to make up for misalignments, may provide clearances in the connections by means of bolts 20, 21, 25 and 26.

D'ailleurs, une certaine capacité d'adaptation est due à la liaison lâche entre le manchon 14, la broche 16 et les plaques 7 et 8. Besides, a certain adaptability is due to the loose connection between the sleeve 14, the spindle 16 and the plates 7 and 8.
