Description

L'invention a trait à un dispositif de projection de produit de revêtement comprenant un élément rotatif de pulvérisation, tel qu'un bol ou une coupelle, entraîné en rotation à haute vitesse par des moyens d'entraînement tels qu'un rotor d'une turbine à air. L'invention a également trait à un élément rotatif de pulvérisation pouvant être utilisé avec ce dispositif.The invention relates to a coating product spraying device comprising a rotary spray element, such as a bowl or cup, rotated at high speed by drive means such as a rotor of a air turbine. The invention also relates to a rotary spray element that can be used with this device.

Dans une installation de projection de produit de revêtement, liquide ou particulaire, il est connu de pulvériser le produit au moyen d'un bol ou d'une coupelle alimentée en produit et tournant à une vitesse de l'ordre de 30 000 tours/minute. A une telle vitesse de rotation, il est souhaitable que le bol ou la coupelle soit le plus léger possible et équilibré afin d'éviter, autant que faire se peut, les balourds, notamment si la turbine d'entraînement est une turbine à palier à air et/ou magnétique.In a liquid or particulate coating product spraying installation, it is known to spray the product by means of a bowl or cup which is fed with product and rotating at a speed of the order of 30,000 revolutions / minute. . At such a rotational speed, it is desirable that the bowl or cup is as light as possible and balanced in order to avoid, as far as possible, unbalance, especially if the drive turbine is a turbine with a bearing. air and / or magnetic.

Il est connu d'assembler un élément rotatif de pulvérisation au rotor d'une turbine au moyen d'une tige filetée s'étendant axialement par rapport au rotor et d'un taraudage axial de l'élément rotatif ou bol ou par des boulons répartis circonférentiellement autour de l'axe de rotation de cet élément. Un tel type d'assemblage alourdit considérablement l'ensemble tournant alors que les opérations de montage et de démontage sont longues et fastidieuses, ce qui n'est pas forcément compatible avec les temps de maintenance disponibles, notamment sur une chaîne de production de véhicules automobiles.It is known to assemble a rotary spray element to the rotor of a turbine by means of a threaded rod extending axially with respect to the rotor and of an axial thread of the rotary element or bowl or by bolts distributed circumferentially around the axis of rotation of this element. Such a type of assembly considerably weighs the rotating assembly while assembly and disassembly operations are long and tedious, which is not necessarily compatible with the maintenance time available, especially on a production line of motor vehicles .

WO-A-94/12286 divulgue un dispositif de projection comprenant un bol relié au rotor d'un pulvérisateur grâce à une couronne d'emboîtement susceptible d'expansion radiale. Ce système donne satisfaction.WO-A-94/12286 discloses a projection device comprising a bowl connected to the rotor of a sprayer by means of a nesting ring capable of radial expansion. This system gives satisfaction.

US-A-4,473,188 divulgue un matériel d'épandage comprenant une buse rotative entraînée par un moteur électrique. L'accouplement entre cette buse et l'arbre de sortie du moteur a lieu par appui d'une bague métallique solidaire de la buse sur un aimant entraîné par cet arbre. Cet appui surfacique pré-suppose un positionnement précis de la buse par rapport à l'arbre, ce qui limite la vitesse de rotation de la buse. En outre, si des particules métalliques se déposent sur l'aimant, l'appui surfacique de la bague n'est plus possible, ce qui gêne l'accouplement entre la buse et l'arbre du moteur. De plus, les mises en places successives de buses sur l'arbre peuvent abimer la surface de l'aimant destinée à recevoir, en appui, les bagues des buses. Ce dispositif n'est donc pas adapté à la projection de produit de revêtement pour laquelle il doit être régulièrement procédé au nettoyage et/ou à l'échange d'un bol, avec mise en place subséquente de ce bol ou d'un nouveau bol.US-A-4,473,188 discloses spreading equipment comprising a rotary nozzle driven by an electric motor. Coupling between this nozzle and the motor output shaft takes place by support of a metal ring integral with the nozzle on a magnet driven by this shaft. This surface support presupposes a precise positioning of the nozzle relative to the shaft, which limits the speed of rotation of the nozzle. In addition, if metal particles are deposited on the magnet, the surface support of the ring is no longer possible, which hinders the coupling between the nozzle and the motor shaft. In addition, the successive places of nozzles on the shaft can damage the surface of the magnet intended to receive, in support, the rings of the nozzles. This device is not suitable for the projection of coating product for which it must be regularly cleaned and / or exchanged a bowl, with subsequent introduction of this bowl or a new bowl .

L'invention vise à proposer une solution alternative à celle connue de WO-A-94/12286 qui est particulièrement simple sur le plan structurel, donc fiable et d'un prix de revient attractif, et compatible avec la projection de produit de revêtement.The invention aims to provide an alternative solution to that known from WO-A-94/12286 which is particularly simple structurally, therefore reliable and an attractive cost, and compatible with the projection of coating product.

Dans cet esprit, l'invention concerne un dispositif de projection de produit de revêtement du type précité qui comprend des moyens de couplage magnétique entre l'élément rotatif de pulvérisation et les moyens d'entraînement associés et qui est caractérisé en ce qu'un entrefer est ménagé entre ces moyens de couplage magnétique.In this spirit, the invention relates to a coating product spraying device of the aforementioned type which comprises means for magnetic coupling between the rotary spray element and the associated drive means and which is characterized in that a gap is provided between these magnetic coupling means.

Grâce à l'utilisation de moyens de couplage magnétique, le montage et le démontage de l'élément rotatif de pulvérisation sur ses moyens d'entraînement sont particulièrement rapides puisqu'il suffit d'approcher l'élément rotatif suffisamment près des moyens d'entraînement pour que le couplage magnétique produise un effet de solidarisation efficace. Ces moyens de couplage permettent également un centrage magnétique de l'élément rotatif par rapport au rotor. Comme un entrefer est ménagé entre les moyens de couplage magnétique, il n'y a pas de risque de matage des surfaces en regard des moyens de couplage, même après plusieurs mises en place de bol. De plus, un éventuel dépôt de particules métalliques ou d'impuretés sur l'une de ces surfaces en regard ne gêne pas le fonctionnement des moyens de couplage. La mise en place d'un bol ne requiert donc pas de précautions particulières.Thanks to the use of magnetic coupling means, the assembly and disassembly of the rotary spray element on its drive means are particularly rapid since it is sufficient to approach the rotary element sufficiently close to the drive means for the magnetic coupling to produce an effective bonding effect. These coupling means also allow magnetic centering of the rotary element relative to the rotor. As an air gap is provided between the magnetic coupling means, there is no risk of matting of the surfaces facing the coupling means, even after several bowl implementations. In addition, a possible deposition of metal particles or impurities on one of these surfaces opposite does not interfere with the operation of the coupling means. The establishment of a bowl does not require special precautions.

Selon un premier mode de réalisation de l'invention, l'élément rotatif est équipé d'au moins un aimant apte à coopérer avec un élément de bouclage magnétique porté par les moyens d'entraînement.According to a first embodiment of the invention, the rotary element is equipped with at least one magnet adapted to cooperate with a magnetic looping element carried by the drive means.

Selon un autre mode de réalisation avantageux de l'invention, les moyens d'entraînement sont équipés d'au moins un aimant apte à coopérer avec un élément de bouclage magnétique porté par l'élément rotatif.According to another advantageous embodiment of the invention, the drive means are equipped with at least one magnet capable of cooperating with a magnetic looping element carried by the rotary element.

Selon un troisième mode de réalisation de l'invention, l'élément rotatif et le rotor sont chacun pourvus d'un aimant, les polarités de ces aimants étant orientées de telle sorte qu'une force d'attraction est générée entre ces aimants lors du montage de l'élément rotatif sur le rotor.According to a third embodiment of the invention, the rotating element and the rotor are each provided with a magnet, the polarities of these magnets being oriented so that a force of attraction is generated between these magnets during the mounting the rotary member on the rotor.

Quel que soit le mode de réalisation considéré, l'aimant permanent peut être en forme d'anneau ou de secteur d'anneau centré sur l'axe de rotation de l'élément rotatif. En variante, plusieurs aimants en forme de secteurs d'anneau ou de plots sont répartis autour de l'axe de rotation. De même, l'élément de bouclage peut être un anneau métallique centré sur l'axe de rotation de l'élément rotatif.Whatever the embodiment considered, the permanent magnet may be in the form of a ring or ring sector centered on the axis of rotation of the rotary element. Alternatively, several magnets in the form of ring sectors or pads are distributed around the axis of rotation. Similarly, the looping element may be a metal ring centered on the axis of rotation of the rotary element.

Selon un autre aspect avantageux de l'invention, l'aimant et/ou l'élément de bouclage est emmanché à force dans un logement ménagé dans l'élément rotatif ou dans les moyens d'entraînement.According to another advantageous aspect of the invention, the magnet and / or the looping element is forced into a housing formed in the rotary element or in the drive means.

Selon un autre aspect avantageux de l'invention, le dispositif comprend des moyens de centrage mécanique de l'élément rotatif de pulvérisation par rapport aux moyens d'entraînement. Ces moyens de centrage permettent un pré-positionnement des moyens de couplage magnétique lors de la mise en place de l'élément de pulvérisation sur les moyens d'entraînement. Ces moyens de centrage contribuent également au bon maintien de l'élément de pulvérisation sur ses moyens d'entraînement. Dans ce cas, on peut prévoir que l'élément rotatif comprend au moins une surface tronconique de portée contre une surface tronconique correspondante des moyens d'entraînement. Avantageusement, une surface tronconique de l'élément rotatif est ménagée sensiblement autour des moyens de couplage magnétique. On peut, en outre, prévoir qu'une surface tronconique des moyens d'entraînement est ménagée au niveau d'un bord libre d'une jupe définissant un volume de réception partielle de l'élément rotatif.According to another advantageous aspect of the invention, the device comprises means for mechanical centering of the rotary spray element relative to the drive means. These centering means allow a pre-positioning of the magnetic coupling means during the introduction of the spray element on the drive means. These centering means also contribute to the proper maintenance of the spray element on its drive means. In this case, it can be provided that the rotary element comprises at least one frustoconical bearing surface against a corresponding frustoconical surface of the means drive. Advantageously, a frustoconical surface of the rotary element is formed substantially around the magnetic coupling means. It can further be provided that a frustoconical surface of the drive means is provided at a free edge of a skirt defining a partial receiving volume of the rotating element.

Selon un autre aspect avantageux de l'invention, les moyens de couplage magnétique constituent également des moyens d'auto-centrage de l'élément rotatif sur le rotor, ce qui permet d'envisager la suppression totale ou partielle des moyens de centrage mécanique.According to another advantageous aspect of the invention, the magnetic coupling means also constitute self-centering means for rotating the element on the rotor, which makes it possible to envisage the total or partial elimination of the mechanical centering means.

L'invention concerne également un élément rotatif ou bol de pulvérisation et un organe d'entraînement susceptibles d'être utilisés avec un dispositif tel que précédemment décrit. L'élément rotatif de pulvérisation porte des moyens aptes à coopérer avec des moyens complémentaires prévus sur un organe d'entraînement pour la solidarisation par couplage magnétique du bol et de l'organe en question, alors que le bol est pourvu d'une surface d'appui contre une surface correspondante de cet organe dans une position telle qu'un entrefer est ménagé entre les moyens de couplage magnétique précités qui coopèrent.The invention also relates to a rotary element or spray bowl and a drive member that can be used with a device as previously described. The rotary spray element carries means adapted to cooperate with complementary means provided on a drive member for the magnetic coupling connection of the bowl and the member in question, while the bowl is provided with a surface of pressing against a corresponding surface of this member in a position such that an air gap is provided between the aforementioned magnetic coupling means which cooperate.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre de deux modes de réalisation d'un dispositif de projection de produit de revêtement conformes à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

Aux figures 1 et 2, le rotor 1 d'une turbine à palier à air est partiellement représenté. Il est symétrique autour de son axe de rotation X-X' et forme deux surfaces tronconiques 11 et 12 également centrées sur l'axe X-X' et évasées en direction de l'extérieur de la turbine à laquelle appartient le rotor 1, c'est-à-dire vers l'avant du dispositif de projection de l'invention.In Figures 1 and 2, the rotor 1 of an air bearing turbine is partially shown. It is symmetrical about its axis of rotation XX 'and forms two frustoconical surfaces 11 and 12 also centered on the axis XX' and flared in direction of the outside of the turbine to which belongs the rotor 1, that is to say towards the front of the projection device of the invention.

Compte tenu de son mode d'entraînement par une turbine à palier à air, le rotor 1 peut atteindre des vitesses de rotation de plusieurs dizaines de milliers de tour à la minute, par exemple de l'ordre de 30 000 tr/mn, voire de 80 000 tr/mn pour une turbine dite "à haute vitesse".Given its drive mode by an air bearing turbine, the rotor 1 can reach rotational speeds of several tens of thousands of revolutions per minute, for example of the order of 30,000 rpm, or even 80,000 rpm for a turbine called "high speed".

Dans la présente description, les qualificatifs "avant" et "arrière" s'entendent par rapport à une configuration de fonctionnement du dispositif, le côté avant étant orienté vers l'objet à revêtir alors que le côté arrière est orienté à l'opposé.In the present description, the qualifiers "front" and "back" refer to an operating configuration of the device, the front side being oriented towards the object to be coated while the rear side is facing the opposite.

Le rotor 1 forme également une jupe 13 globalement cylindrique et centrée sur l'axe X-X', la surface 12 étant ménagée au niveau du bord libre 13a de la jupe 13, radialement à l'intérieur de ce bord libre.The rotor 1 also forms a generally cylindrical skirt 13 and centered on the axis X-X ', the surface 12 being provided at the free edge 13a of the skirt 13, radially inwardly of the free edge.

Le rotor 1 forme également un logement 14 de réception d'un anneau 2 réalisé en fer doux. Le logement 14 comprend un épaulement 14a et une surface radiale externe 14b contre lesquels l'anneau 2 est emmanché à force comme représenté par les flèches F1 à la figure 1, l'anneau 2 étant immobilisé dans le logement 14 par coopération de formes.The rotor 1 also forms a housing 14 for receiving a ring 2 made of soft iron. The housing 14 includes a shoulder 14a and a radially outer surface 14 b against which the ring 2 is press-fitted as shown by arrows F 1 in Figure 1, the ring 2 being fixed in the housing 14 by cooperation of forms.

Un bol 3 est destiné à être monté sur le rotor 1 afin d'être entraîné en rotation à haute vitesse autour de l'axe X-X'. Ce bol comprend une partie centrale 31 destinée à être disposée dans le volume interne de la jupe 13 en regard du débouché 51 d'un tube 5 d'alimentation du bol 3 en produit de revêtement, ce tube 5 étant également centré sur l'axe X-X'. Le tube 5 permet une alimentation axiale, par son côté arrière, du bol 3. La partie centrale 31 du bol 3 est reliée à un bord de pulvérisation 32 par un voile 33 sur lequel le produit de revêtement se répartit par centrifugation. Des canaux 34 ménagés dans la partie 31 permettent l'écoulement du produit de revêtement de la face arrière 31a de la partie 31 vers la face avant 33a du voile 33, puis vers le bord 32.A bowl 3 is intended to be mounted on the rotor 1 in order to be rotated at high speed around the axis X-X '. This bowl comprises a central portion 31 intended to be disposed in the internal volume of the skirt 13 facing the outlet 51 of a tube 5 for feeding the bowl 3 with a coating product, this tube 5 being also centered on the axis XX '. The tube 5 allows axial feeding, by its rear side, of the bowl 3. The central portion 31 of the bowl 3 is connected to a spray edge 32 by a web 33 on which the coating product is distributed by centrifugation. Channels 34 formed in the part 31 allows the flow of the coating material of the rear face 31a of the portion 31 towards the front face 33 a of the plate 33 and towards the edge 32.

Une première surface tronconique 35 est prévue au niveau du bord arrière 36 du bol 3, à l'extérieur de celui-ci, cette surface 35 étant convergente en direction de l'amont du tube 5. L'angle α1 d'ouverture de la surface 35 autour de l'axe X-X' est sensiblement égal à l'angle α2 d'ouverture de la surface 11 autour de ce même axe, de sorte qu'une portée surfacique de la surface 35 sur la surface 11 peut être envisagée.A first frustoconical surface 35 is provided at the the rear edge 36 of the bowl 3, outside thereof, this surface 35 being convergent towards the upstream of the tube 5. The angle α 1 of opening of the surface 35 about the axis XX is substantially equal to the angle α 2 of opening of the surface 11 around this same axis, so that a surface area of the surface 35 on the surface 11 can be considered.

Le bol 3 forme également une seconde surface tronconique 37 également convergente vers l'axe X-X' en direction de l'amont du tube 5 et dont on note β1 l'angle d'ouverture. Cet angle est sensiblement égal à l'angle β2 d'ouverture de la surface 12 autour de l'axe X-X'.The bowl 3 also forms a second frustoconical surface 37 also converging towards the axis XX 'towards the upstream of the tube 5 and whose opening angle is noted β 1 . This angle is substantially equal to the opening angle β 2 of the surface 12 around the axis X-X '.

La distance d1 entre les zones médianes des surfaces 11 et 12 est sensiblement égale à la distance d 2 entre les zones médianes des surfaces 35 et 36, de sorte qu'un appui simultané des surfaces 35 et 37 respectivement sur les surfaces 11 et 12 peut être obtenu. En pratique, la coopération des surfaces 35 et 11 d'une part, 37 et 12 d'autre part permet, de par l'orientation de ces surfaces, d'obtenir un centrage du bol 3 sur l'axe X-X'. Un guidage ou pré-positionnement pourrait également être obtenu avec un seul jeu de surfaces coopérantes 35 et 11 ou 37 et 12.The distance d 1 between the median regions of the surfaces 11 and 12 is substantially equal to the distance d 2 between the median areas of the surfaces 35 and 36, so that a simultaneous pressing of the surfaces 35 and 37 respectively on the surfaces 11 and 12 can be obtained. In practice, the cooperation of the surfaces 35 and 11 on the one hand, 37 and 12 on the other hand, by the orientation of these surfaces, to obtain a centering of the bowl 3 on the axis X-X '. Guiding or pre-positioning could also be obtained with a single set of cooperating surfaces 35 and 11 or 37 and 12.

Conformément à l'invention, le bol 3 est équipé d'un aimant permanent 4 de forme annulaire qui est monté dans un logement 38 ménagé au niveau du bord arrière 36 du bol 3. Le logement 31 forme un épaulement 38a et une surface radiale 38b globalement cylindrique qui permettent un emmanchement à force de l'aimant 4 dans le logement 38 comme représenté par les flèche F2.According to the invention, the bowl 3 is equipped with a permanent magnet 4 of annular shape which is mounted in a housing 38 formed at the rear edge 36 of the bowl 3. The housing 31 forms a shoulder 38 and has a radial surface 38 b generally cylindrical which allow a force fitting of the magnet 4 in the housing 38 as represented by the arrow F 2 .

L'aimant 4 est annulaire mais un anneau comprenant plusieurs aimants permanents pourrait être également utilisé à la place de l'aimant 4. Selon une autre alternative, plusieurs aimants en forme de plots peuvent être répartis à l'arrière du bol 3, par exemple trois aimants répartis à 120°.The magnet 4 is annular but a ring comprising several permanent magnets could also be used in place of the magnet 4. According to another alternative, several magnets in the form of pads may be distributed at the rear of the bowl 3, for example three magnets distributed at 120 °.

Lorsque le bol 3 est monté sur le rotor 1 comme représenté sur la figure 2, l'aimant 4 est disposé en regard de l'anneau en fer doux 2, un entrefer e étant ménagé du fait de la portée de la surface 35 et 37 sur les surfaces 11 et 12.When the bowl 3 is mounted on the rotor 1 as shown in FIG. 2, the magnet 4 is arranged opposite the soft iron ring 2, an air gap e being formed because of the range of the surface 35 and 37. on surfaces 11 and 12.

Les éléments 2 et 4 permettent de réaliser un couplage magnétique intense entre le rotor 1 et le bol 3, l'anneau 2 permettant de refermer le champ magnétique généré par l'aimant 4. On obtient ainsi un effort d'attraction représenté par les flèche F3 à la figure 3, cet effort contribuant à plaquer fortement les surfaces 35 et 37 sur des surfaces 11 et 12, ce qui contribue à une immobilisation axiale et en rotation du bol 3 par rapport au rotor 1. Le bol 3 est immobilisé en rotation par rapport au rotor 1 grâce aux forces de frottement entre leurs surfaces en contact. On peut en outre envisager un blocage en rotation du bol 3 sur le rotor 1 par un dispositif mécanique, par exemple du type clavette.The elements 2 and 4 make it possible to carry out an intense magnetic coupling between the rotor 1 and the bowl 3, the ring 2 making it possible to close the magnetic field generated by the magnet 4. This gives an attraction force represented by the arrow F 3 in FIG. 3, this force contributing to strongly pressing the surfaces 35 and 37 on surfaces 11 and 12, which contributes to axial immobilization and rotation of the bowl 3 with respect to the rotor 1. The bowl 3 is immobilized by rotation relative to the rotor 1 thanks to the friction forces between their surfaces in contact. It is also possible to envisage blocking of the bowl 3 on the rotor 1 by a mechanical device, for example of the key-type, in rotation.

Lors de la mise en place du bol 1 sur le rotor 3, il suffit à un opérateur d'approcher le bol 3 du rotor 1 en utilisant les surfaces 11, 12, 35 et 36 comme moyens de guidage jusqu'à ce que l'entrefer e entre l'aimant 4 et l'anneau 2 soit suffisamment faible pour que la force d'attraction magnétique entre les éléments 2 et 4 plaque fermement le bol 3 sur le rotor 1.When placing the bowl 1 on the rotor 3, it is sufficient for an operator to approach the bowl 3 of the rotor 1 by using the surfaces 11, 12, 35 and 36 as guiding means until the The gap e between the magnet 4 and the ring 2 is small enough that the magnetic attraction force between the elements 2 and 4 firmly plates the bowl 3 on the rotor 1.

La forme des surfaces 12 et 35 définit la largeur de l'entrefer e. The shape of the surfaces 12 and 35 defines the width of the gap e.

Les éléments de couplage magnétique 2 et 4 sont disposés autour du tube 5. En d'autres termes, le dispositif de l'invention est compatible avec une alimentation axiale ou centrale du bol en produit de revêtement, par son côté arrière.The magnetic coupling elements 2 and 4 are arranged around the tube 5. In other words, the device of the invention is compatible with an axial or central feed of the bowl coating product, by its rear side.

Lorsqu'il convient de démonter le bol 3 par rapport au rotor 1, il suffit d'exercer sur le bol 3 un effort d'extraction globalement parallèle à l'axe x-x' et opposé à l'effort d'attraction magnétique représenté par les flèches F3.When it is necessary to disassemble the bowl 3 relative to the rotor 1, it is sufficient to exert on the bowl 3 an extraction force generally parallel to the axis xx 'and opposite to the magnetic attraction force represented by the arrows F 3 .

Aucun outillage spécifique n'est nécessaire, le montage et le démontage du bol 3 étant particulièrement simples et rapides.No specific tools are necessary, the assembly and disassembly of the bowl 3 being particularly simple and fast.

Dans le second mode de réalisation de l'invention représenté à la figure 3, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 100.In the second embodiment of the invention shown in FIG. 3, elements similar to those of the first embodiment carry identical references increased by 100.

Le bol 103 de ce mode de réalisation est destiné à être monté sur un rotor 101 d'une turbine à air. Le bol 103 est équipé d'un anneau 102 en fer doux, emmanché dans un logement 138 ménagé à proximité du bord arrière 136 du bol 103. Le rotor 101 est équipé d'un anneau 104 formé de plusieurs aimants 104a, 104b, 104c etc .... en forme de secteurs d'anneau.The bowl 103 of this embodiment is intended to be mounted on a rotor 101 of an air turbine. The bowl 103 has a ring 102 of soft iron, fitted in a recess 138 formed near the rear edge 136 of the bowl 103. The rotor 101 has a ring 104 formed of a plurality of magnets 104 a, 104 b, 104 c etc .... in the form of ring sectors.

L'anneau 104 est reçu dans un logement 114 formé à l'intérieur du rotor 101.The ring 104 is received in a housing 114 formed inside the rotor 101.

Comme les éléments 2 et 4, les éléments 102 et 104 ont sensiblement le même rayon, de sorte qu'il permettent d'obtenir un couplage magnétique efficace entre le bol 103 et le rotor 101, un entrefer e étant ménagé entre eux.Like the elements 2 and 4, the elements 102 and 104 have substantially the same radius, so that they make it possible to obtain an effective magnetic coupling between the bowl 103 and the rotor 101, an air gap e being formed between them.

Des surfaces tronconiques 112 et 135 sont respectivement prévues sur le rotor 111 et le bol 103. Elles définissent la position relative des éléments 101 et 103 sous l'effet de l'attraction exercée par les éléments de couplage 102 et 104. En particulier, la largeur de l'entrefer e dépend de la position de ces surfaces.Frustoconical surfaces 112 and 135 are respectively provided on the rotor 111 and the bowl 103. They define the relative position of the elements 101 and 103 under the effect of the attraction exerted by the coupling elements 102 and 104. In particular, the gap width e depends on the position of these surfaces.

Ce mode de réalisation présente l'avantage particulier que l'anneau 104 qui constitue la partie active des moyens de couplage magnétique entre le rotor et le bol est logé à l'intérieur du rotor 101, de sorte qu'il est protégé contre d'éventuelles impuretés, l'anneau 102 ne risquant pas d'attirer des particules métalliques ou de la limaille lorsqu'il est démonté et stocké à l'extérieur de l'installation de projection à laquelle appartient le dispositif de l'invention.This embodiment has the particular advantage that the ring 104 which constitutes the active part of the magnetic coupling means between the rotor and the bowl is housed inside the rotor 101, so that it is protected against possible impurities, the ring 102 not likely to attract metal particles or filings when disassembled and stored outside the projection installation to which the device of the invention belongs.

Ce mode de réalisation permet en outre de prévoir que les aimants 104a, 104b, 104c .... de l'anneau 104 sont des électro-aimants commandés par des moyens appropriés montés sur le rotor 101. Ceci permet d'activer ou non ces aimants en fonction du montage ou du démontage du bol 103.This embodiment also makes it possible to provide that the magnets 104 a , 104 b , 104 c, of the ring 104 are electromagnets controlled by appropriate means mounted on the rotor 101. This makes it possible to activate or not these magnets according to the assembly or disassembly of the bowl 103.

Il est également possible de prévoir dans ce second mode de réalisation, un seul électro-aimant de forme annulaire, de façon analogue à ce qui est décrit en référence au premier mode de réalisation de l'invention.It is also possible to provide in this second embodiment, a single annular electromagnet, similar to that described with reference to the first embodiment of the invention.

Les anneaux 2 et 102 peuvent être monobloc ou réalisés en plusieurs pièces. Ils sont en métal, de préférence en fer doux, en acier ou en un autre matériau ferromagnétique.The rings 2 and 102 may be monobloc or made in several pieces. They are made of metal, preferably iron soft, steel or other ferromagnetic material.

Selon une variante non représentée de l'invention, deux aimants permanents peuvent être utilisés pour réaliser le couplage magnétique. Un aimant est monté sur le bol alors que le second est monté sur le rotor, les polarités de ces aimants étant orientées pour obtenir une attraction d'un aimant par rapport à l'autre lorsqu'on montre le bol sur le rotor. En fait, dans ce cas, l'élément de bouclage magnétique, qui est constitué par les anneaux 2 et 102 des modes de réalisation décrits, est constitué par le second aimant.According to a not shown variant of the invention, two permanent magnets can be used to perform the magnetic coupling. A magnet is mounted on the bowl while the second is mounted on the rotor, the polarities of these magnets being oriented to obtain an attraction of a magnet relative to the other when showing the bowl on the rotor. In fact, in this case, the magnetic looping element, which is constituted by the rings 2 and 102 of the embodiments described, is constituted by the second magnet.

Quel que soit le mode de réalisation considéré, les moyens de couplage magnétique entre le bol et le rotor, qui sont essentiellement symétriques autour de l'axe de rotation du rotor et du bol, permettent d'obtenir un auto-centrage du bol sur le rotor.Whatever the embodiment considered, the magnetic coupling means between the bowl and the rotor, which are essentially symmetrical about the axis of rotation of the rotor and the bowl, make it possible to obtain a self-centering of the bowl on the rotor.
