Abstract
Description
La présente invention se rapporte aux palettes 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 equilibrium support or of pallet bonding 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 Falette 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 Falette 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 et vise une palette caractérisée en ce qu'elle montre une portion courbe de contact avec la surface d'application statorique, améliorant le frottement et une portion compensatrice exposée à la pression prépondérante du fluide, pour que cette pression s'exerce sensiblement perpendiculairement à la surface d'application statorique, de sorte que tout soulèvement ou décollement intempestif de la palette dû notamment à la portion courbe de celle-ci, soit immédiatement compensé par ladite pression venant suppléer au moyen existant d'application de palette. The present invention intends to improve the friction of each pallet on the stator application surface while keeping constant support of the pallet on this surface and aims at a pallet characterized in that it shows a curved portion of contact with the surface of stator application, improving friction and a compensating portion exposed to the preponderant pressure of the fluid, so that this pressure is exerted substantially perpendicular to the surface of stator application, so that any untimely lifting or detachment of the pallet due in particular to the curved portion thereof, either immediately offset by said pressure supplementing the existing means of pallet application.
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'inzentronX représentée dans son logement rotorique et venant en appui d'équilibre de palette contre le stator du dispositif
- 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 InzentronX represented in its rotor housing and coming into pallet balance support against the stator of the device
- 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 (S1) 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 represented in FIG. 1, a pallet according to the invention (1) shows a curved or rounded portion (2) of surface (S1) coming, according to a generator (G) in equilibrium contact of the pallet with 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 surface of stator application.
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 (S1) et (S2) sont choisies égales de manière à obtenir l'équilibre de palette recherché. In the embodiment shown in Figure 1 the surfaces (S1) 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 pallet. . 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 zone 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 de celle de la figure 1, à la différence toutefois, que la surface (S2) est choisie supérieure à la surface (S1) 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 of that of Figure 1, with the difference however, that the surface (S2) is chosen greater than the surface (S1) so that the pallet is in support of bonding against the stator application surface (3A).
En vue d'obtenir un contact satisfaisant d'appui de collage la portion courbe de surface (S1) 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 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 (fig. 1) ou le contact d'appui de collage (fig. 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 (fig. 1) or the bonding support contact (fig. 2) are chosen according to the possible use version of the hydraulic or electro-hydraulic rotary device considered: pump, motor version, brake or retarder.

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 .
