Description

La présente invention se rapporte auxpalettes coulissantes de rotor de dispositifs hydrauliques ou électrohydrauliques rotatifs, lesquelles palettes sont susceptibles de venir en appui d'équilibre de palette ou en appui de collage de palette contre une surface d'application statorique.The present invention relates to rotor sliding pallets of rotary hydraulic or electrohydraulic devices, which pallets are capable of coming into pallet balance support or pallet gluing support against a stator application surface.

Une usure importante peut se produire entre les arêtes vives de chaque palette et la surface d'application statorique, allant jusqu'à une détérioration rapide, d'autant plus si ladite surface d'application est une rampe, les variations de profil de la rampe accentuant encore le frottement.Significant wear can occur between the sharp edges of each pallet and the stator application surface, up to a rapid deterioration, all the more if said application surface is a ramp, the variations in profile of the ramp further accentuating the friction.

Il doit être remarqué, par ailleurs, que l'appui des palettes coulissantes sur la surface d'application statorique ou rampe doit être constant. Cet appui est généralement obtenu à l'aide d'un moyen d'application de palette qui peut être constitué par un ressort, un aimant - ou une bobine d'attraction.It should also be noted that the support of the sliding pallets on the stator application surface or ramp must be constant. This support is generally obtained using a pallet application means which can be constituted by a spring, a magnet - or an attraction coil.

La présente invention entend améliorer le frottement de chaque palette sur la surface d'application statorique tout en gardant un appui constant de la palette sur cette surface, cette palette coulissante devant, par ailleurs, fonctionner suivant les deux sens de rotation possibles du rotor du dispositif hydraulique rotatif qui comporte ladite palette (ou lesdites palettes).The present invention intends to improve the friction of each pallet on the stator application surface while keeping a constant support of the pallet on this surface, this sliding pallet having, moreover, to operate according to the two possible directions of rotation of the rotor of the device. rotary hydraulic which comprises said pallet (or said pallets).

On connaît un moteur ou une pompe à palettes radiales à un seul sens de rotation. Chaque palette de ce moteur ou de cette pompe montre une arête aiguë contre une surface statorique.There is known a motor or a radial vane pump with a single direction of rotation. Each pallet of this motor or pump shows a sharp edge against a stator surface.

Des méplats sont réalisés devant et derrière l'arête, l'un de ces méplats étant plus grand que l'autre.Flats are made in front of and behind the ridge, one of these flats being larger than the other.

Suivant le sens de rotation unique adopté, le méplat étroit constitue un méplat avant. Dans une zone active de fonctionnement, le méplat étroit est exposé à la haute pression ce qui force la palette radialement vers l'intérieur du rotor.According to the unique direction of rotation adopted, the narrow flat constitutes a front flat. In an active operating zone, the narrow flat part is exposed to high pressure, which forces the paddle radially towards the inside of the rotor.

Une autre surface est réalisée à l'opposé du méplat étroit pour constituer un moyen d'application de la palette contre la surface statorique.Another surface is created opposite the narrow flat to constitute a means of application of the pallet against the stator surface.

Une autre surface s'étendant latéralement à la palette permet l'exercice d'une pression latérale sur la palette, de manière à l'appliquer contre la paroi de son logement.Another surface extending laterally to the pallet allows lateral pressure to be exerted on the pallet, so as to apply it against the wall of its housing.

Il s'agit, dans l'ensemble, d'un type connu de palette.It is, on the whole, a known type of palette.

On connait un moteur rotatif à palettes coulissantes radialement et susceptible de tourner dans les deux sens. La palette montre, de part et d'autre d'elle-même, une entaille. Un canal permet à la pression de fluide de s'exercer contre la palette pour la "pousser" contre la paroi opposée du logement recevant la palette.We know a rotary motor with radially sliding vanes and capable of rotating in both directions. The palette shows, on both sides of itself, a notch. A channel allows the fluid pressure to be exerted against the pallet to "push" it against the opposite wall of the housing receiving the pallet.

Aucune disposition n'est cependant prévue pour améliorer le frottement de la palette contre la surface statorique.No provision is however made to improve the friction of the pallet against the stator surface.

On connait, enfin, un dispositif dans lequel. une palette est flottante dans un logement statorique. La palette agit radialement sous l'action d'un ressort. Des cavités latérales sont pratiquées sur la palette et une pluralité de petits passages relient une cavité à la cavité aval. En fonctionnement, la haute pression est transmise par des passages à la- cavité aval de la palette de manière à équilibrer la force qui s'exerce sur la cavité opposée.We know, finally, a device in which. a pallet is floating in a stator housing. The pallet acts radially under the action of a spring. Lateral cavities are formed on the pallet and a plurality of small passages connect a cavity to the downstream cavity. In operation, the high pressure is transmitted through passages to the downstream cavity of the pallet so as to balance the force exerted on the opposite cavity.

Cette disposition vise à conserver à la palette son caractère flottant dans un dispositif rotatif formant pompe ou moteur à un seul sens de rotation.This provision aims to keep the pallet its floating character in a rotary device forming a pump or motor with a single direction of rotation.

La présente invention vise une palette coulissante de rotor de dispositifs hydrauliques rotatifs, laquelle palette est susceptible de venir en appui d'équilibre de palette ou en appui de collage de palette contre une surface d'application statorique, du type à moyen d'application de palette tel un ressort et/ou une surface d'application exposée à la pression du fluide et pouvant être, de plus, pourvu d'une surface s'étendant latéralement et se poursuivant sur une certaine longueur à l'intérieur du logement de la palette pratiqué dans le rotor, laquelle palette est caractérisée en ce qu'elle est symétrique de part et d'autre d'un axe médian (Z-Z), et en ce qu'elle montre de part et 'd'autre d'elle-même une portion courbe (2) de contact avec la surface d'application statorique (3), améliorant le frottement, tout soulèvement ou décollement intempestif de la palette, dû notamment à ladite portion courbe, étant immédiatement compensé par le moyen existant d'application de palette qui est associé à cette portion courbe, le comportement de la palette étant le même, que la pression vienne d'un côté ou de l'autre par rapport audit axe (Z-Z).The present invention relates to a rotor sliding pallet of rotary hydraulic devices, which pallet is capable of coming into pallet balance support or pallet gluing support against a stator application surface, of the type with application of pallet such as a spring and / or an application surface exposed to the pressure of the fluid and which may also be provided with a surface extending laterally and continuing over a certain length inside the pallet housing formed in the rotor, which pallet is characterized in that it is symmetrical on either side of a median axis (ZZ), and in that that it shows on both sides of itself a curved portion (2) of contact with the stator application surface (3), improving friction, any untimely lifting or detachment of the pallet, due in particular to said curved portion, being immediately compensated for by the existing means of applying a pallet which is associated with this curved portion, the behavior of the pallet being the same, whether the pressure comes from one side or the other with respect to said axis (ZZ).

D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre faite en regard du dessin annexé sur lequel :

  • la figure 1 est une vue en coupe schématique d'une palette coulissante selon l'invention, représentée dans son logement rotorique et venant en appui d'équilibre de palette contre le stator du dispositif ; et
  • la figure 2 est une vue en coupe schématique, semblable à celle de la figure 1, dans laquelle la palette est en appui de collage de palette contre le stator du dispositif.
Other characteristics and advantages of the present invention will emerge from the description which follows made with reference to the appended drawing in which:
  • Figure 1 is a schematic sectional view of a sliding pallet according to the invention, shown in its rotor housing and coming into pallet balance support against the stator of the device; and
  • Figure 2 is a schematic sectional view, similar to that of Figure 1, in which the pallet is in abutment for gluing the pallet against the stator of the device.

Dans la forme de réalisation représentée à la figure 1, une palette selon l'invention (1) montre une portion courbe ou arrondie (2) de surface (Sl) venant, suivant une génératrice (G) en contact d'équilibre de palette avec le stator (3) aussi bien du côté amont (pression prépondérante HP) que du côté aval (pression xP). Ces pressions s'exercent sur les portions courbes et ont tendance à soulever la palette, mais cette tendance est immédiatement combattue du fait d'une portion compensatrice (4) de la palette, de surface (S2), sur laquelle la pression de fluide s'exerce sensiblement perpendiculairement à la surface d'application statorique (3A) du stator. La surface de la portion compensatrice (4) de la palette est donc sensiblement parallèle à ladite surface d'application statorique.In the embodiment shown in FIG. 1, a pallet according to the invention (1) shows a curved or rounded portion (2) of surface (Sl) coming, according to a generator (G) in equilibrium contact with the pallet the stator (3) both on the upstream side (preponderant pressure HP) and on the downstream side (pressure xP). These pressures are exerted on the curved portions and tend to lift the pallet, but this tendency is immediately combated due to a compensating portion (4) of the pallet, of surface (S2), on which the fluid pressure s 'exercises substantially perpendicular to the stator application surface (3A) of the stator. The surface of the compensating portion (4) of the pallet is therefore substantially parallel to said stator application surface.

La palette (1) est percée d'au moins un canal d'équilibrage hydraulique (5)'une pression (x'P) régnant alors à l'intérieur de la palette et du logement (6) qui la reçoit dans le rotor (7) avec interposition d'un moyen d'application de palette (8) qui, en l'occurrence, est un ressort. Les pressions (xP) et (x'P) sont inférieures à la pression (HP).The pallet (1) is pierced with at least one hydraulic balancing channel (5) ' a pressure (x'P) then prevailing inside the pallet and the housing (6) which receives it in the rotor ( 7) with the interposition of a pallet application means (8) which, in this case, is a spring. The pressures (xP) and (x'P) are lower than the pressure (HP).

Dans la forme de réalisation représentée à la figure 1, les surfaces (Sl) et (S2) sont choisies égales de manière à obtenir l'équilibre de palette recherché.In the embodiment shown in Figure 1, the surfaces (Sl) and (S2) are chosen equal so as to obtain the desired pallet balance.

Par ailleurs, la palette (1) est pourvue d'une surface supplémentaire (S3) exposée à la pression (HP), cette surface s'étendant latéralement à la palette et se poursuivant à l'intérieur du logement sur une certaine longueur de la palette. La surface (S3), creusée latéralement dans la palette, permet d'éviter tout basculement de celle-ci sous l'action de la pression prépondérante (HP) dans la zone de la palette normalement exposée à cette pression. L'exercice de la pression (HP) sur la surface latérale (S3) permet, de plus, d'établir une étanchéité de la palette contre son logement, sur une ligne de contact (9) de ces deux pièces, se situant en arête arrière de la face latérale de la palette, opposée à celle exposée à la pression (HP).Furthermore, the pallet (1) is provided with an additional surface (S3) exposed to pressure (HP), this surface extending laterally to the pallet and continuing inside the housing over a certain length of the palette. The surface (S3), hollowed out laterally in the pallet, makes it possible to avoid any tilting of the latter under the action of the preponderant pressure (HP) in the area of the pallet normally exposed to this pressure. The exercise of pressure (HP) on the lateral surface (S3) also makes it possible to establish a seal of the pallet against its housing, on a contact line (9) of these two parts, located at the edge back of the side face of the pallet, opposite to that exposed to pressure (HP).

Il doit être remarqué que la palette est symétrique de part et d'autre de son axe de symétrie (Z-Z) de sorte que le comportement de la palette soit le même, que la pression (HP) vienne d'un côté ou de l'autre, par rapport à cet axe.It should be noted that the pallet is symmetrical on either side of its axis of symmetry (ZZ) so that the behavior of the pallet is the same, whether the pressure (HP) comes from one side or from the other, in relation to this axis.

La forme de réalisation de la figure 2 montre les mêmes caractéristiques et dispositions que celles de la figure 1, à la différence toutefois que la surface (S2) est choisie supérieure à la surface (Sl) de sorte que la palette soit en appui de collage contre la surface d'application statorique (3A).The embodiment of Figure 2 shows the same characteristics and provisions as those of Figure 1, with the difference however that the surface (S2) is chosen greater than the surface (Sl) so that the pallet is in bonding support against the stator application surface (3A).

En vue d'obtenir un contact satisfaisant d'appui de collage, la portion courbe de surface (Sl) est suivie d'une zone ou bandeau (10) de contact avec la surface d'application statorique (3A). On a vu que dans la forme de réalisation de la figure 1 le contact se résume à une génératrice (G).In order to obtain satisfactory contact with the bonding support, the curved surface portion (S1) is followed by a zone or strip (10) in contact with the stator application surface (3A). We have seen that in the embodiment of FIG. 1, the contact comes down to a generator (G).

Le contact d'appui d'équilibre (figure 1) ou le contact d'appui de collage (figure 2) sont choisis en fonction de la version d'utilisation possible du dispositif hydraulique ou électrohydraulique rotatif considéré : version pompe, moteur, frein ou ralentisseur.The balance support contact (Figure 1) or the bonding support contact (Figure 2) are chosen according to the possible use version of the hydraulic or electro-hydraulic rotary device considered: pump, motor, brake or retarder.

Il est bien entendu que la présente invention n'a été décrite et représentée qu'à titre d'exemple préférentiel et qu'on pourra apporter des équivalences sans, pour autant, sortir du cadre de ladite invention qui est défini dans les revendications qui suivent.It is understood that the present invention has only been described and shown as a preferred example and that equivalences can be made without, however, departing from the scope of said invention which is defined in the claims which follow .
