Description

Domaine technique : Technical field :

L'invention concerne un actionneur d'entraînement d'un écran d'occultation enroulable, et plus particulièrement, d'un écran de fermeture tel qu'une grille, une porte enroulable ou un volet.The invention relates to a driving actuator for a roll-up blinding screen, and more particularly to a closing screen such as a grid, a roll-up door or a shutter.

Etat de la technique : State of the art :

Habituellement, une installation de fermeture comprend un tube, immobilisé par rapport à un bâti, sur lequel est fixé un actionneur. Celui-ci permet l'enroulement d'un tablier souple autour d'une couronne appartenant à l'actionneur. Compte tenu de la taille et du poids de l'écran, l'installation comprend souvent des moyens élastiques de compensation du poids de l'écran, de manière à faciliter son déplacement. Ceci permet d'optimiser le dimensionnement de l'actionneur, celui-ci nécessitant moins de puissance que si aucun moyen de compensation n'est prévu.Usually, a closure installation comprises a tube, immobilized relative to a frame, on which is fixed an actuator. This allows the winding of a flexible apron around a crown belonging to the actuator. Given the size and weight of the screen, the installation often includes elastic means of compensation of the weight of the screen, so as to facilitate its movement. This optimizes the dimensioning of the actuator, the latter requiring less power than if no means of compensation is provided.

La structure d'un tel actionneur est décrite dans les demandes de brevet FR-A-2 394 667 et FR-A-2 783 866 . Elle comprend un moteur électrique fixé sur un tube et qui entraîne en rotation une couronne sur laquelle est attachée une extrémité du tablier souple à enrouler. Généralement, l'actionneur comprend également un dispositif de comptage, solidaire des moyens de fixation du moteur sur le tube et permettant de connaître la position du tablier.The structure of such an actuator is described in the patent applications FR-A-2,394,667 and FR-A-2 783 866 . It comprises an electric motor fixed on a tube and which rotates a crown on which is attached one end of the flexible deck to wind. Generally, the actuator also comprises a counting device, secured to the motor fixing means on the tube and to know the position of the deck.

Dans la demande FR-A-2 394 667 , l'immobilisation de l'actionneur sur le tube est réalisée par deux vis, disposées à 180°, exerçant chacune une pression directe sur le tube. Une vis est en prise avec un siège en forme de U et l'autre en prise avec un chapeau complémentaire. Cette solution présente l'inconvénient d'un serrage local sur une faible zone. En conséquence, pour assurer une bonne tenue de l'actionneur, la pression exercée par les vis doit être importante, ce qui peut détériorer le tube. D'autre part, les vis sont sollicitées de façon importante, de même que le siège et le chapeau, ce qui impose un dimensionnement plus strict. Enfin, le risque de désolidarisation de l'actionneur par dévissage est double dans la mesure où le dévissage peut avoir lieu au niveau de chacune des deux vis.In the request FR-A-2,394,667 immobilization of the actuator on the tube is performed by two screws, arranged at 180 °, each exerting a direct pressure on the tube. One screw is engaged with a U-shaped seat and the other engaged with a complementary cap. This solution has the disadvantage of a local clamping on a small area. Consequently, to ensure good behavior of the actuator, the pressure exerted by the screws must be high, which can damage the tube. On the other hand, the screws are solicited significantly, as well as the seat and the hat, which imposes a sizing more strict. Finally, the risk of uncoupling of the actuator by unscrewing is double insofar as the unscrewing can take place at each of the two screws.

Dans la demande FR-A-2 783 866 , les moyens de fixations sont constitués d'un support et d'une bride montée sur le support. La tenue de l'actionneur sur le tube est obtenue par pression de la bride et du support contre le tube. Cette pression est réalisée par un boulon dont la tige traverse la bride, le support et le tube. Cette solution nécessite de percer le tube de part en part afin de réaliser deux trous diamétralement opposés pour le passage de la tige du boulon. Ces trous résultent d'opérations supplémentaires qui fragilisent le tube. Pour des actionneurs à fort couple, cette solution peut détériorer les moyens de fixations ou le tube, sans un dimensionnement strict des éléments.In the request FR-A-2 783 866 , the fastening means consist of a support and a flange mounted on the support. The holding of the actuator on the tube is obtained by pressing the flange and the support against the tube. This pressure is achieved by a bolt whose rod passes through the flange, the support and the tube. This solution requires drilling the tube from side to side to make two diametrically opposed holes for the passage of the bolt rod. These holes result from additional operations that weaken the tube. For high torque actuators, this solution can damage the fastening means or the tube, without a strict dimensioning of the elements.

Il est par ailleurs connu de FR-A-2 549 890 d'utiliser deux brides et des boulons pour monter un ensemble motorisé sur un arbre fixe. Les boulons sont au contact de l'arbre qu'ils peuvent mater et affaiblir mécaniquement. En outre, les deux brides pincent l'arbre entre elles car elles exercent un effort de blocage sur deux portions diamétralement opposées du tube.It is also known from FR-A-2,549,890 use two flanges and bolts to mount a motorized assembly on a fixed shaft. The bolts are in contact with the tree that they can mater and weaken mechanically. In addition, the two flanges pinch the shaft between them because they exert a locking force on two diametrically opposite portions of the tube.

Exposé de l'invention : Presentation of the invention

L'invention propose un actionneur d'entraînement d'un écran enroulable autour d'un tube fixe comprenant des moyens de fixation au tube. Cet actionneur est caractérisé en ce que les moyens de fixation comportent au moins trois pièces aptes à exercer chacune, par contact direct avec le tube, un effort de serrage sur le tube lorsque deux des trois pièces sont rapprochées par des moyens de réglage de l'effort de serrage, ces moyens de réglage étant distants de la surface extérieure du tube.The invention proposes a drive actuator for a screen that can be wound around a fixed tube comprising tube attachment means. This actuator is characterized in that the fastening means comprise at least three parts each capable of exerting, by direct contact with the tube, a clamping force on the tube when two of the three parts are brought together by adjustment means of the clamping force, these adjustment means being remote from the outer surface of the tube.

Ainsi ces moyens de réglage se situent radialement, au-delà du diamètre extérieur du tube. Ils ne sont pas nécessairement très éloignés du tube car ce qui importe, c'est surtout de permettre d'éviter tout contact, entre ces moyens de réglage et le tube, de nature à fragiliser le tube. De ce fait, ces moyens de réglage ne traversent pas le tube.Thus these adjustment means are located radially, beyond the outer diameter of the tube. They are not necessarily very far from the tube because what matters is mainly to avoid any contact between these adjustment means and the tube, such as to weaken the tube. As a result, these adjustment means do not pass through the tube.

Cette disposition particulière des moyens de réglage de l'effort de serrage permet d'assurer la fixation de l'actionneur en s'affranchissant d'une découpe diamétrale du tube pouvant le fragiliser. L'utilisation d'au moins deux pièces en contact avec le tube permet de répartir la pression de serrage et donc de diminuer la contrainte exercée sur le tube.This particular arrangement means for adjusting the clamping force ensures the attachment of the actuator by avoiding a diametrical cut of the tube may weaken. The use of at least two parts in contact with the tube distributes the clamping pressure and thus reduces the stress exerted on the tube.

Comme les moyens de fixation comportent au moins trois pièces aptes à exercer chacune une pression de serrage sur le tube, la pression de serrage est mieux répartie et plus équilibrée. Les moyens de fixation contraignent plus faiblement le tube.As the fixing means comprise at least three parts each capable of exerting a clamping pressure on the tube, the clamping pressure is better distributed and more balanced. The fixing means constrain the tube more weakly.

Préférentiellement, I trois pièces sont utilisées et forment un support et deux mors mobiles par rapport au support. Le rapprochement des deux mors l'un par rapport à l'autre a pour effet de pousser le tube vers le support. Une fois les trois pièces en contact avec le tube, si on poursuit le rapprochement des deux mors, on influe directement sur le serrage sur le tube. Par cette configuration, la fixation de l'actionneur sur le tube est facilitée car il suffit d'une seule opération consistant à rapprocher les deux mors. En conséquence, en utilisant un seul moyen de réglage de l'écartement des deux mors, on peut maîtriser la pression de serrage des moyens de fixation. Ces moyens de réglage de l'écartement des mors correspondent à des moyens de réglage de l'effort de serrage. Ce peut être un boulon ou tout autre moyen approprié. Les moyens de réglage du serrage ne permettent pas forcément plusieurs niveaux de serrage. Par exemple, la fixation de l'actionneur est obtenue lorsque les mors ont un certain écartement grâce à un moyen de verrouillage permettant de maintenir ses positions indexées.Preferably, three pieces are used and form a support and two movable jaws relative to the support. The approximation of the two jaws relative to each other has the effect of pushing the tube towards the support. Once the three parts in contact with the tube, if we continue the approximation of the two jaws, it directly affects the clamping on the tube. By this configuration, the attachment of the actuator on the tube is facilitated because it is sufficient to a single operation of bringing the two jaws. In Consequently, by using a single means for adjusting the spacing of the two jaws, it is possible to control the clamping pressure of the fastening means. These means for adjusting the distance of the jaws correspond to means for adjusting the clamping force. It can be a bolt or any other suitable means. The tightening adjustment means do not necessarily allow several tightening levels. For example, the attachment of the actuator is obtained when the jaws have a certain distance through a locking means to maintain its indexed positions.

Pour diminuer l'encombrement des moyens de fixation, une solution consiste à faire pivoter chaque mors autour d'un arbre solidaire du support ou appartenant au support. L'amplitude du mouvement des mors peut ainsi être réduite.To reduce the size of the fastening means, one solution is to rotate each jaw around a shaft secured to the support or belonging to the support. The amplitude of the movement of the jaws can thus be reduced.

Pour faciliter la réalisation du support, celui-ci peut être composé d'éléments standards et/ou simples à fabriquer. Ainsi, il peut comprendre deux plaques reliées par des arbres dont au moins deux permettent le pivotement des mors.To facilitate the realization of the support, it may be composed of standard elements and / or simple to manufacture. Thus, it may comprise two plates connected by shafts, at least two of which allow the jaws to pivot.

Le montage de l'actionneur peut également être facilité en prévoyant des moyens d'assemblage permettant de limiter le déplacement des mors indépendamment du moyen de réglage de l'effort de serrage. Ainsi, le débattement des mors peut varier entre une position proche du contact avec le tube et une autre position correspondant à un serrage sur le tube.The mounting of the actuator can also be facilitated by providing assembly means for limiting the movement of the jaws independently of the means for adjusting the clamping force. Thus, the movement of the jaws may vary between a position close to the contact with the tube and another position corresponding to a clamping on the tube.

De manière avantageuse, les moyens de fixation permettent d'exercer un effort de serrage sur au moins trois zones distinctes, afin d'améliorer la répartition de la pression exercée sur le tube. Préférentiellement, ces zones sont disposées de manière à ce que l'angle, entre les centres de deux zones de serrage adjacentes par rapport à l'axe du tube, est compris entre 85° et 135°. Au sens de l'invention, une zone de pression ou de serrage correspond à la zone de contact d'une pièce avec le tube sur laquelle s'exerce une pression entre les deux pièces. La zone de pression peut être discontinue. Les zones de pression ne sont pas forcément au même niveau axial.Advantageously, the fastening means make it possible to exert a clamping force on at least three distinct zones, in order to improve the distribution of the pressure exerted on the tube. Preferably, these zones are arranged in such a way that the angle between the centers of two adjacent clamping zones with respect to the axis of the tube is between 85 ° and 135 °. For the purposes of the invention, a pressure or clamping zone corresponds to the zone of contact of a part with the tube on which pressure is exerted between the two parts. The pressure zone may be discontinuous. The pressure zones are not necessarily at the same axial level.

L'immobilisation en rotation et/ou axialement de l'actionneur par rapport à l'axe du tube est obtenue par le serrage via les moyens de fixation. Elle peut être renforcée par un élément des moyens de fixation coopérant avec un relief du tube. Ce peut être par exemple, un téton du support coopérant avec un orifice ménagé dans le tube.The immobilization in rotation and / or axially of the actuator relative to the axis of the tube is obtained by clamping via the fastening means. It can be reinforced by an element of the fastening means cooperating with a relief of the tube. This may be for example, a nipple of the support cooperating with an orifice in the tube.

Pour rendre compact l'actionneur, les moyens de fixation peuvent être disposés au moins partiellement à l'intérieur de la couronne entraînée par le moteur électrique.To compact the actuator, the fastening means may be arranged at least partially inside the ring gear driven by the electric motor.

Description des modes de réalisation : Description of the embodiments :

Dans l'installation de fermeture I représentée à la figure 1, un actionneur 1 selon l'invention est destiné à enrouler d'un tablier souple non représenté, autour d'un tube 2 fixe par rapport à un bâti non représenté. On note X2 l'axe longitudinal du tube 2.In the closing device I represented at figure 1 , an actuator 1 according to the invention is intended to wind a not shown flexible apron around a fixed tube 2 relative to a not shown frame. X 2 is the longitudinal axis of the tube 2.

L'actionneur 1 comprend deux moteurs électriques 31 et 32 fixés sur le tube grâce à des moyens de fixation 4. Dans ce mode de réalisation, les moyens de fixation portent des roulements 5a, 5b et 5c de guidage, en rotation autour de l'axe X2, d'une couronne 6. Cette couronne 6 est entraînée en rotation respectivement par les pignons de sortie 311 et 321 des moteurs 31 et 32.The actuator 1 comprises two electric motors 31 and 32 fixed to the tube by means of fixing means 4. In this embodiment, the fixing means carry bearings 5a, 5b and 5c for guiding, rotating around the X axis 2 , a ring 6. This ring 6 is rotated respectively by the output gears 311 and 321 of the motors 31 and 32.

Les moyens de fixation 4 supportent également un dispositif 7 de comptage du nombre de tours réalisés par la couronne 6 grâce à un pignon 701 en prise avec cette couronne. La couronne 6 est composée de deux demi-couronnes 61 et 62. Une extrémité du tablier est attachée sur la couronne par une vis 8, représentée par son axe et vissée dans un taraudage 611 prévu à cet effet sur la couronne 61.The fixing means 4 also support a device 7 counting the number of turns made by the ring 6 by a pinion 701 engaged with this ring. The ring 6 is composed of two half-rings 61 and 62. One end of the apron is attached to the ring by a screw 8, represented by its axis and screwed into a tapping 611 provided for this purpose on the ring 61.

Les moyens de fixation sont décrits en référence aux figures 2 à 5 illustrant le tube 2 et ces moyens. Ces moyens de fixation 4 comprennent deux plaques identiques 410 et 420 en acier, espacées parallèlement à l'axe X2, d'une distance d4. Pour simplifier la description, les caractéristiques d'une seule plaque seront détaillées, à savoir celles de la plaque 410, la seconde plaque 420, qui est omise sur les figures 3 à 5, reprenant les mêmes spécificités.The fixing means are described with reference to Figures 2 to 5 illustrating the tube 2 and these means. These fastening means 4 comprise two identical steel plates 410 and 420 spaced parallel to the axis X 2 by a distance d 4 . To simplify the description, the characteristics of a single plate will be detailed, namely those of the plate 410, the second plate 420, which is omitted on the Figures 3 to 5 , taking again the same specificities.

La plaque 410 comprend deux pattes 417a et 417b délimitant entre elles une ouverture 411, la plaque 410 étant globalement en forme de « U ». L'ouverture 411 est destinée à recevoir le tube 2. Au fond de l'ouverture 411, un téton 412 s'étend, à partir du bord 411 A de cette ouverture, vers l'intérieur de l'ouverture 411. La plaque 410 comprend également deux trous 413 permettant de faire passer les pignons 311 et 321. La plaque 410 comprend également un trou 414 assurant le passage du pignon 701. La plaque 410 comporte plusieurs trous 415 permettant de fixer les moteurs 31 et 32, ainsi que le dispositif de comptage 7, au moyen de vis non représentées.The plate 410 comprises two tabs 417a and 417b delimiting between them an opening 411, the plate 410 being generally shaped "U". The opening 411 is intended to receive the tube 2. At the bottom of the opening 411, a pin 412 extends, from the edge 411 A of this opening, towards the inside of the opening 411. The plate 410 also includes two holes 413 for passing the pinions 311 and 321. The plate 410 also comprises a hole 414 ensuring the passage of the pinion 701. The plate 410 has several holes 415 for fixing the motors 31 and 32, and the device counting 7, by means of screws not shown.

La plaque 410 comprend également des trous 416 permettant de fixer des arbres filetés 43a, 43b et 43c au moyen d'écrous borgnes 434. Les arbres 43a, 43b et 43c assurent le support des trois roulements 5a, 5b et 5c et de bagues 441a, 442a, 441b, 442b, 441c et 442c disposées respectivement de part et d'autre de ces roulements, le long de ces arbres. La bague 442c n'est pas visible sur les figures mais sa position se déduit de celle des bagues 442b et 442a. Chaque paire de bagues et la bague interne du roulement correspondant servent d'entretoises et maintiennent l'écartement axial entre les plaques 410 et 420 à la valeur choisie de la distance d4. Cette distance d4 correspond donc à la somme des longueurs de deux bagues, du type de la bague 441a, avec la largeur de la bague interne d'un roulement. Les roulements permettent de guider la couronne 6 autour de l'axe X2 du tube 2. Les bagues 441a, 442a, 441b et 442b permettent également à deux mors 45a et 45b de pivoter autour des axes longitudinaux X43a et X43b des arbres 43a et 43b.The plate 410 also comprises holes 416 for fixing threaded shafts 43a, 43b and 43c by means of blind nuts 434. The shafts 43a, 43b and 43c provide support for the three bearings 5a, 5b and 5c and rings 441a, 442a, 441b, 442b, 441c and 442c disposed respectively on either side of these bearings, along these trees. The ring 442c is not visible in the figures but its position is deduced from that of the rings 442b and 442a. Each pair of rings and the inner ring of the corresponding bearing serve as spacers and maintain the axial spacing between the plates 410 and 420 at the chosen value of the distance d 4 . This distance d 4 thus corresponds to the sum of the lengths of two rings, of the type of the ring 441a, with the width of the inner ring of a bearing. The bearings make it possible to guide the ring 6 around the axis X 2 of the tube 2. The rings 441a, 442a, 441b and 442b also allow two jaws 45a and 45b to pivot about the longitudinal axes X 43a and X 43b of the shafts 43a. and 43b.

Les axes X43a et X43b sont parallèles à l'axe X2 lorsque l'arbre 2 est reçu dans le logement 411.The X axes 43a and X 43b are parallel to the axis X 2 when the shaft 2 is received in the housing 411.

Les roulements 5a et 5b sont omis aux figures 3 à 5, pour la clarté du dessin.The bearings 5a and 5b are omitted at Figures 3 to 5 , for the sake of clarity.

Les arbres 43a et 43b sont montés respectivement sur les pattes 417a et 417b, donc positionnés de part et d'autre de l'ouverture 411. Ils sont proches de l'extrémité de chaque patte 417a et 417b. Chaque patte 417a ou 417b de la plaque 410 comporte un flanc ou bord 419a ou 419b et est pourvue d'une ouverture 418a ou 418b à proximité de son extrémité.The shafts 43a and 43b are respectively mounted on the tabs 417a and 417b, thus positioned on either side of the opening 411. They are close to the end of each leg 417a and 417b. Each tab 417a or 417b of the plate 410 has a flank or edge 419a or 419b and is provided with an opening 418a or 418b near its end.

La plaque 420 est identique à la plaque 410. Elle a une forme globale en U et comprend également des pattes 427a et 427b définissant entre elles une ouverture 421 de réception du tube 2, ces pattes comprenant respectivement chacune, à proximité de leur extrémité, un flanc ou bord 429a ou 429b et une ouverture 428a ou 428b. La plaque 420 est pourvue de trous 433, 424 et 425 analogues aux trous 413, 414 et 415 de la plaque 410.The plate 420 is identical to the plate 410. It has an overall U shape and also comprises tabs 427a and 427b defining between them an opening 421 for receiving the tube 2, these tabs respectively comprising, each near their end, a flank or edge 429a or 429b and an opening 428a or 428b. The plate 420 is provided with holes 433, 424 and 425 similar to the holes 413, 414 and 415 of the plate 410.

Les plaques 410 et 420 et les arbres 43a, 43b et 43c constituent ensemble un support 40 globalement en forme de U sur lequel sont rapportés, entre autres, les moteurs 31 et 32 et le dispositif de comptage 7.The plates 410 and 420 and the shafts 43a, 43b and 43c together constitute a generally U-shaped support 40 on which are mentioned, inter alia, the motors 31 and 32 and the counting device 7.

Les moyens de fixation 4 sont immobilisés axialement et en rotation par coopération entre des tétons 412 et 422 des deux plaques 410 et 420 et des orifices 21 pratiqués dans le tube. Les deux mors 45a et 45b sont identiques. La description d'un seul mors est détaillée dans ce qui suit, ses caractéristiques étant reproduites à l'identique sur l'autre mors. Le mors 45b est formé par une plaque de métal pliée en « U », avec deux pattes symétriques 4511b et 4512b perpendiculaires à une base 452b. Une découpe 4531b, 4532b en arc de cercle est ménagée sur un des deux bords latéraux de chaque extrémité des pattes 4511b et 4512b. Ces deux découpes 4531b et 4532b sont du même coté et viennent coopérer respectivement avec la surface radiale externe des bagues 441b et 442b pour permettre le pivotement du mors 45b autour de l'axe X432. Chaque patte 4511b ou 4512b comprend également une languette déformable 4541b ou 4542b située sur le même bord latéral que la découpe 4531b ou 4532b et proche de celle-ci. Cette languette 4541b ou 4542b s'étend vers l'extérieur du « U » formé par le mors 45b.The fastening means 4 are immobilized axially and in rotation by cooperation between pins 412 and 422 of the two plates 410 and 420 and orifices 21 made in the tube. The two jaws 45a and 45b are identical. The description of a single jaw is detailed in the following, its characteristics being reproduced identically on the other jaw. The jaw 45b is formed by a metal plate bent "U", with two symmetrical lugs 4511b and 4512b perpendicular to a base 452b. A cutout 4531b, 4532b in an arc of circle is formed on one of the two lateral edges of each end of the tabs 4511b and 4512b. These two cutouts 4531b and 4532b are on the same side and cooperate respectively with the outer radial surface of the rings 441b and 442b to allow the jaw 45b to pivot about the X axis 432 . Each tab 4511b or 4512b also includes a deformable tab 4541b or 4542b located on the same side edge as the cut 4531b or 4532b and close thereto. This tongue 4541b or 4542b extends outwardly of the "U" formed by the jaw 45b.

La base 452b est pourvue d'une ouverture 4521b de passage de la tige 91 d'une vis 9 associée à un écrou 10. Ce sont cette vis 9 et cet écrou 10 qui constituent, pour ce mode de réalisation, les moyens de réglage de l'effort de serrage, au sens de l'invention.The base 452b is provided with an opening 4521b for the passage of the rod 91 of a screw 9 associated with a nut 10. It is this screw 9 and this nut 10 which constitute, for this embodiment, the adjustment means of the clamping force, within the meaning of the invention.

Le mors 45a comprend également deux pattes 4511a et 4512a perpendiculaires à une base 452a et dans lesquelles sont respectivement ménagées deux découpes 4531a et 4532a à proximité desquelles s'étendent deux languettes élastiques déformables 4541a et 4542a. Grâce aux découpes 4531 a et 4532a, le mors 45a peut être articulé autour de l'axe X43a de l'arbre 43a, en appui sur les bagues 441a et 442a. La base 452a est percée d'une ouverture 4521a de passage de la tige 91.The jaw 45a also comprises two tabs 4511a and 4512a perpendicular to a base 452a and in which are respectively formed two cutouts 4531a and 4532a near which extend two deformable resilient tongues 4541a and 4542a. With the cutouts 4531a and 4532a, the jaw 45a can be articulated around the X axis 43a of the shaft 43a, bearing on the rings 441a and 442a. The base 452a is pierced with an opening 4521a for passage of the rod 91.

Lorsque les mors 45a et 45b sont respectivement articulés sur les arbres 43a et 43b, il est possible d'amener leurs bases 452a et 452b en regard l'une de l'autre, en alignant sensiblement les ouvertures 4521a et 4521b, puis d'y engager la tige 91 de la vis 9. Ceci permet, en serrant l'écrou 10 sur la tige 91, de régler la position des mors 45a et 45b autour de l'axe X2 et d'exercer un effort de serrage plus ou moins intense sur le tube 2 en place dans l'ouverture 411.When the jaws 45a and 45b are respectively articulated on the shafts 43a and 43b, it is possible to bring their bases 452a and 452b facing each other, substantially aligning the openings 4521a and 4521b, and then engage the rod 91 of the screw 9. This allows, by tightening the nut 10 on the rod 91, to adjust the position of the jaws 45a and 45b around the axis X 2 and exert a more or less intense clamping force on the tube 2 in place in the opening 411.

Pour faciliter ce réglage, les ouvertures 4521a et 4521b sont de formes oblongues dans le sens radial par rapport au tube 2. La largeur de ces ouvertures est légèrement supérieure au diamètre de la tige 91.To facilitate this adjustment, the openings 4521a and 4521b are oblong in the radial direction relative to the tube 2. The width of these openings is slightly greater than the diameter of the rod 91.

Les moyens de fixation 4 comprennent donc le support 40, les deux mors 45a et 45b et les moyens de réglage de l'effort de serrage formés par la vis 9 et l'écrou 10.The fastening means 4 thus comprise the support 40, the two jaws 45a and 45b and the means for adjusting the clamping force formed by the screw 9 and the nut 10.

Le montage de l'actionneur 1 sur le tube 2 est représenté aux figures 6 à 8.The mounting of the actuator 1 on the tube 2 is shown in Figures 6 to 8 .

Dans une première étape représentée à la figure 6, on déplace le support 40 équipé ou non de moteurs 31 et 32 et/ou d'un dispositif de comptage 7 vers le tube 2 selon une direction centripète par rapport à l'axe X2, comme représenté par la flèche F1, jusqu'à engager les tétons 412 dans les orifices 21. On peut alors monter les mors 45a et 45b sur les arbres 43a et 43b, comme représenté par les flèches F2a et F2b à la figure 7. Pour ce faire, on coiffe les bagues 441a, 442a, 441b et 442b respectivement avec les découpes 4531 a, 4532a, 4531b et 4532b des mors 45a et 45b. Dans cette position, les mors sont maintenus en position grâce à la coopération d'une part, des bagues 441a, 442a, 441b et 442b respectivement avec les découpes 4531a, 4532a, 4531b et 4532b, et d'autre part, des languettes 4541a, 4541b, 4542a et 4542b respectivement avec les flancs 419a, 419b, 429a et 429b.In a first step represented in figure 6 , the support 40 with or without motors 31 and 32 and / or a counting device 7 is moved towards the tube 2 in a centripetal direction with respect to the axis X 2 , as represented by the arrow F 1 , until to engage the nipples 412 in the orifices 21. The jaws 45a and 45b can then be mounted on the shafts 43a and 43b, as represented by the arrows F 2a and F 2b at the figure 7 . To do this, the rings 441a, 442a, 441b and 442b are capped respectively with the cutouts 4531a, 4532a, 4531b and 4532b of the jaws 45a and 45b. In this position, the jaws are held in position by cooperation on the one hand, the rings 441a, 442a, 441b and 442b respectively with the cuts 4531a, 4532a, 4531b and 4532b, and on the other hand, the tabs 4541a, 4541b, 4542a and 4542b respectively with flanks 419a, 419b, 429a and 429b.

On peut alors rabattre les mors 45a et 45b en direction du tube 2, comme représenté par les flèches F3a et F3b à la figure 8, de telle sorte que les bases 452a et 452b sont sensiblement en regard l'une de l'autre. Pour obtenir cette configuration, le déplacement des mors implique la déformation élastique des languettes 4541a, 4541b, 4542a et 4542b vers l'intérieur du « U » formé par un mors. Une fois placé dans cette configuration, les languettes reprennent une position plus stable en s'engageant respectivement dans les ouvertures 418a, 418b, 428a et 428b des plaques 410 et 420. Plus précisément, les languettes 4541a et 4541b sont respectivement engagées dans les ouvertures 428a et 428b de la plaque 420, alors que les languettes 4542a et 4542b sont engagées dans les ouvertures 418a et 418b de la plaque 410. Ceci permet de retenir les mors 45a et 45b en configuration de pré-serrage où ils ne sont pas forcement en appui contre le tube 2 mais où leurs bases 452a et 452b sont proches l'une de l'autre, dans une configuration où il est relativement facile pour l'operateur d'engager la tige 91 de la vis 9 dans les ouvertures 4521a et 4521b, comme représenté par la flèche F4 puis de venir visser l'écrou 10 sur cette tige, comme représenté par la flèche F5.We can then fold the jaws 45a and 45b towards the tube 2, as represented by the arrows F 3a and F 3b at the figure 8 , so that the bases 452a and 452b are substantially facing each other. To obtain this configuration, the displacement of the jaws involves the elastic deformation of the tongues 4541a, 4541b, 4542a and 4542b towards the inside of the "U" formed by a jaw. Once placed in this configuration, the tabs take up a more stable position by engaging respectively in the openings 418a, 418b, 428a and 428b of the plates 410 and 420. More specifically, the tabs 4541a and 4541b are respectively engaged in the openings 428a. and 428b of the plate 420, while the tongues 4542a and 4542b are engaged in the openings 418a and 418b of the plate 410. This makes it possible to hold the jaws 45a and 45b in pre-clamping configuration where they are not necessarily in support against the tube 2 but where their bases 452a and 452b are close to each other, in a configuration where it is relatively easy for the operator to engage the rod 91 of the screw 9 in the openings 4521a and 4521b, as represented by the arrow F 4 and then to screw the nut 10 on this rod, as represented by the arrow F 5 .

Lorsque les languettes déformées sont en place dans les ouvertures 418a et 418b, l'opérateur peut lâcher les mors 45a et 45b pour attraper la vis 9 et l'écrou 10, sans risque que les mors ne pivotent vers la configuration de la figure 3, puisque les languettes limitent le pivotement des mors. Ainsi, l'actionneur ne risque pas de se désengager inopinément du tube, les ouvertures 4521a et 4521b sont sensiblement alignées ce qui facilite la mise en place ultérieure de la tige 91 dans ces ouvertures.When the deformed tongues are in place in the openings 418a and 418b, the operator can release the jaws 45a and 45b to catch the screw 9 and the nut 10, without the risk that the jaws will pivot to the configuration of the figure 3 , since the tabs limit the pivoting of the jaws. Thus, the actuator is not likely to disengage unexpectedly from the tube, the openings 4521a and 4521b are substantially aligned which facilitates the subsequent introduction of the rod 91 in these openings.

Une fois la vis 9 et l'écrou 10 en place, le serrage de l'écrou 10 sur la tige 91 a pour effet de rapprocher les bases 452a et 452b au point que les mors 45a et 45b sont fermement plaqués contre la surface radiale externe du tube 2. La vis 9 et l'écrou 10 permettent de régler l'intensité de l'effort de serrage ou d'appui des mors 45a et 45b sur le tube 2. Les mors 45a et 45b sont en contact direct de la surface extérieure 22 du tube 2.Once the screw 9 and the nut 10 are in place, the tightening of the nut 10 on the rod 91 has the effect of bringing the bases 452a and 452b so close that the jaws 45a and 45b are firmly pressed against the outer radial surface 2. The screw 9 and the nut 10 make it possible to adjust the intensity of the force of clamping or supporting the jaws 45a and 45b on the tube 2. The jaws 45a and 45b are in direct contact with the surface. outside 22 of the tube 2.

On est alors dans la position de la figure 4 où le mors 45a exerce sur le tube 2 un effort centripète de serrage Ea dirigé vers l'axe X2. De la même façon, le mors 45b exerce sur le tube 2 un effort de serrage centripète Eb dirigé vers l'axe X2. Les efforts Ea et Eb plaquent fermement le tube 2 au creux de l'étrier, sur les bords 411 A et 421 A des ouvertures 411 et 421, ce qui a pour effet, d'une part, d'assurer un contact direct entre la surface extérieure 22 du tube 2 et les plaques 410 et 420 et, d'autre part, de générer un effort de réaction ER, également centripète et dirigé vers l'axe X2. En pratique, l'effort ER est exercé par les plaques 410 et 420 directement sur la surface 22. Cet effort ER est la combinaison de deux efforts individuels ERa et ERb qui s'exercent de part et d'autre du téton 412 de chaque plaque 410 ou 420. Les deux efforts ERa et ERb ont pour résultante l'effort ER qui s'exerce sous la forme de deux composantes unitaires dans le prolongement de chaque téton 412, c'est-à-dire au niveau des plaques 410 et 420.We are in the position of the figure 4 where the jaws 45a exerts on the tube 2 a centripetal clamping force E directed towards the axis X 2. In the same way, the jaw 45b exerts on the tube 2 a centripetal tightening force E b directed towards the axis X 2 . The forces E a and E b firmly clamp the tube 2 in the hollow of the stirrup, on the edges 411 A and 421 A of the openings 411 and 421, which has the effect, on the one hand, of ensuring a direct contact between the outer surface 22 of the tube 2 and the plates 410 and 420 and, secondly, to generate a reaction force E R , also centripetal and directed towards the axis X 2 . In practice, the force E R is exerted by the plates 410 and 420 directly on the surface 22. This effort E R is the combination of two individual forces E Ra and E Rb which are exerted on both sides of the nipple 412 of each plate 410 or 420. The two efforts E Ra and E Rb result in the effort E R which is exercised in the form of two unitary components in the extension of each pin 412, that is to say at the plates 410 and 420.

Comme les mors 45a et 45b sont situés axialement entre les plaques 410 et 420, les efforts Ea et Eb s'exercent axialement entre les composantes unitaires de l'effort ER. Les efforts Ea et Eb, d'une part et les deux composantes unitaires de l'effort ER exercées par les plaques 410 et 420 sont donc décalés axialement le long de l'axe X2.As the jaws 45a and 45b are located axially between the plates 410 and 420, the forces E a and E b are exerted axially between the unit components of the force E R. The forces E a and E b , on the one hand, and the two unitary components of the force E R exerted by the plates 410 and 420, are therefore axially offset along the axis X 2 .

Les efforts Ea, Eb et ER concourent à l'immobilisation ferme et pérenne de l'actionneur 1 sur le tube 2, sans qu'il soit nécessaire de percer de part en part le tube 2, d'une façon qui aurait tendance à l'affaiblir.Efforts E a , E b and E R contribute to the firm and lasting immobilization of the actuator 1 on the tube 2, without the need to drill through the tube 2, in a manner that would have tendency to weaken it.

A cet égard, la vis 9 et l'écrou 10, qui permettent de régler l'effort de serrage des moyens de fixation 4 sur le tube 2, c'est-à-dire l'intensité des efforts Ea, Eb et ER, sont situés radialement à l'extérieur du tube 2 qu'ils ne traversent pas. En d'autres termes, la vis 9 et l'écrou 10 sont distants de la surface extérieure 22 du tube 2. Ils n'interagissent pas directement avec le tube qu'ils ne fragilisent donc pas.In this respect, the screw 9 and the nut 10, which make it possible to adjust the clamping force of the fastening means 4 on the tube 2, that is to say the intensity of the forces E a , E b and E R , are located radially outside the tube 2 they do not cross. In other words, the screw 9 and the nut 10 are spaced from the outer surface 22 of the tube 2. They do not interact directly with the tube so they do not embrittle.

Comme il ressort plus particulièrement de la figure 4, les efforts Ea, Eb et ER sont repartis sensiblement à 120° autour de l'axe X2, dans un plan perpendiculaire à cet axe.As is clear from the figure 4 , the forces E a , E b and E R are distributed substantially at 120 ° around the axis X 2 , in a plane perpendicular to this axis.

On définit la zone de pression Za du mors 45a sur le tube 2 comme la zone au niveau de laquelle s'exerce l'effort de serrage Ea. De la même façon, on définit la zone de pression Zb du mors 45b sur le tube 2 comme la zone au niveau de laquelle s'exerce l'effort Eb. Les zones Za et Zb sont formées par les bords des pattes 4511a, 4512a, 4511b et 4512b opposées aux découpes 4531a, 4532a, 4531a et 4532a. Ces zones de pression sont également réparties le long de l'axe X2, de fait de l'écartement axial entre les pattes 4511a et 4512a, d'une part, 4511b et 4512b, d'autre part.The pressure zone Z a of the jaw 45a is defined on the tube 2 as the zone at which the clamping force E a is exerted. In the same way, the zone of pressure Z b of the jaw 45b is defined on the tube 2 as the zone at which the force E b is exerted. The zones Z a and Z b are formed by the edges of the tabs 4511a, 4512a, 4511b and 4512b opposite the cutouts 4531a, 4532a, 4531a and 4532a. These pressure zones are also distributed along the axis X 2 , due to the axial spacing between the tabs 4511a and 4512a, on the one hand, 4511b and 4512b, on the other hand.

On définit la zone ZR dans laquelle s'applique l'effort ER comme la zone voisine du téton 412 de chaque ouverture 411.Zone Z R is defined in which the force E R applies as the zone adjacent to the pin 412 of each opening 411.

Les zones Za, Zb et ZR sont réparties à environ 120° autour de l'axe X2, dans le plan de la figure 4. On note respectivement α1, α2 et α3 les angles, autour de l'axe X2 et dans un plan perpendiculaire à cet axe, entre les centres respectifs des zones Za et ZR, Zb et ZR et Za et ZR. En pratique, les angles α1, α2 et α3 ont une valeur comprise entre 85° et 135°.The zones Z a , Z b and Z R are distributed at about 120 ° around the axis X 2 , in the plane of the figure 4 . Α 1 , α 2 and α 3 respectively denote the angles, around the axis X 2 and in a plane perpendicular to this axis, between the respective centers of the zones Z a and Z R , Z b and Z R and Z a and Z R. In practice, the angles α 1 , α 2 and α 3 have a value between 85 ° and 135 °.

Cette répartition régulière ou quasi-régulière des zones de pression ou de serrage de l'actionneur 1 sur le tube 2 limite les déformations localisées du tube 2.This regular or quasi-regular distribution of the pressure or clamping zones of the actuator 1 on the tube 2 limits the localized deformations of the tube 2.

Lorsque l'écrou 10 a été vissé sur la tige 91, avec utilisation éventuelle d'un contre écrou ou tout autre moyen permettant de maintenir le serrage, il est possible de constituer la couronne 6 en rapprochant les deux demi-couronnes 61 et 62, comme représenté par les flèches F61 et F62 à la figure 8. Ces demi-couronnes peuvent alors être solidarisées, d'une façon connue en soi, notamment au moyen de vis non représentées, pour constituer la couronne 6.When the nut 10 has been screwed onto the rod 91, with the possible use of a locknut or any other means making it possible to maintain the tightening, it is possible to constitute the crown 6 by bringing the two half-rings 61 and 62 together, as represented by the arrows F 61 and F 62 at the figure 8 . These half-crowns can then be secured, in a manner known per se, in particular by means of screws not shown, to form the crown 6.

Il convient de relever que la couronne 6 est disposée axialement entre les plaques 410 et 420, de sorte qu'une partie des moyens de fixation formés par les éléments 9, 10, 45a, 45b, 43a et 43b est disposé à l'intérieur de la couronne 6.It should be noted that the ring gear 6 is disposed axially between the plates 410 and 420, so that a part of the fastening means formed by the elements 9, 10, 45a, 45b, 43a and 43b is disposed inside the the crown 6.

Lorsque l'actionneur 1 est immobilisé sur le tube 2, les dentures internes 612 et 622 de la couronne 6 sont en prise respectivement avec les pignons 311, 321 et 701, de sorte qu'il est possible d'entraîner la couronne 6 en rotation, dans un sens ou dans l'autre autour de l'axe X2, grâce aux moteurs 31 et 32, et de contrôler cette rotation, grâce au dispositif de comptage 7.When the actuator 1 is immobilized on the tube 2, the internal teeth 612 and 622 of the ring gear 6 are respectively engaged with the pinions 311, 321 and 701, so that it is possible to drive the ring gear 6 in rotation , in one direction or the other around the axis X 2 , thanks to the motors 31 and 32, and to control this rotation, thanks to the counting device 7.

Il est alors possible de solidariser à la couronne 6 le tablier qui doit être manoeuvré, grâce à la vis 8 et au taraudage 611 mentionnés ci-dessus.It is then possible to secure to the crown 6 the apron to be operated, through the screw 8 and tapping 611 mentioned above.

Il est clair que le mode de réalisation décrit précédemment peut être sujet à variantes. Ainsi, le serrage de l'actionneur sur le tube via les mors peut suffire pour l'immobilisation axiale et en rotation de l'actionneur. En conséquence, les tétons 412 et les orifices 21 du tube pourraient être supprimés. Alternativement, il n'y a qu'un moteur 31 fixé sur le support 40 et/ou il n'y a pas de dispositif de comptage 7 fixé sur ce même support. Les languettes 4541a, 4541b, 4542a et 4542b sont facultatives pour réaliser le serrage. Telles qu'elles sont décrites et représentées, elles permettent de faciliter l'assemblage. Cependant, selon une variante, ces languettes pourraient constituer les moyens de réglage de l'effort de serrage. Les ouvertures 418a, 418b, 428a et 428b sont alors dimensionnées et positionnées de manière à permettre une indexation des mors. Lorsque les mors sont positionnés de manière à assurer un bon serrage, les languettes des mors coopèrent avec les ouvertures pour maintenir les mors dans cette configuration. On peut également imaginer l'aménagement des ouvertures afin d'obtenir plusieurs positions indexées de serrage. D'autres moyens de réglage de l'effort de serrage peuvent être envisagés.It is clear that the embodiment described above may be subject to variations. Thus, the clamping of the actuator on the tube via the jaws can suffice for the axial immobilization and rotation of the actuator. As a result, the nipples 412 and the orifices 21 of the tube could be removed. Alternatively, there is only one motor 31 fixed on the support 40 and / or there is no counting device 7 fixed on the same support. The tabs 4541a, 4541b, 4542a and 4542b are optional for making the clamping. As they are described and represented, they facilitate assembly. However, according to one variant, these tongues could constitute the means for adjusting the clamping force. The openings 418a, 418b, 428a and 428b are then dimensioned and positioned so as to allow indexing of the jaws. When the jaws are positioned to ensure proper clamping, the tongues of the jaws cooperate with the openings to hold the jaws in this configuration. One can also imagine the arrangement of the openings to obtain several indexed clamping positions. Other means of adjusting the clamping force can be envisaged.
