Description

"Machine électrique tournante comportant des moyens de positionnement angulaire de la carcasse par rapport à la plaque porte-charbons" "Rotating electric machine comprising means for angular positioning of the carcass relative to the carbon holder plate"
L'invention concerne une machine électrique tournante comportant des moyens de positionnement angulaire de la carcasse par rapport à la plaque porte-charbons.The invention relates to a rotary electrical machine comprising means for angular positioning of the carcass with respect to the carbon holder plate.
L'invention concerne plus particulièrement un moteur électrique, pour l'entraînement en balayage alterné d'un système d'essuie-glace.The invention relates more particularly to an electric motor, for the drive in alternating sweeping of a wiper system.
L'invention concerne ainsi une machine électrique tournante du type qui comporte un rotor qui tourne autour d'un axe longitudinal de rotation, et qui porte à une extrémité longitudinale arrière un collecteur alimenté électriquement par au moins deux balais qui s'étendent selon une direction sensiblement radiale et dans un plan transversal sensiblement perpendiculaire à l'axe longitudinal de rotation, et qui sont guidés par des moyens fixés sur une plaque transversale porte-charbons, et du type qui comporte une carcasse cylindrique coaxiale de section circulaire de support de ferrites formant stator.The invention thus relates to a rotary electric machine of the type which comprises a rotor which rotates about a longitudinal axis of rotation, and which carries at a rear longitudinal end a collector electrically supplied by at least two brushes which extend in a direction substantially radial and in a transverse plane substantially perpendicular to the longitudinal axis of rotation, and which are guided by means fixed on a carbon brush transverse plate, and of the type which comprises a coaxial cylindrical carcass of circular section supporting ferrites forming stator.
Les moteurs conventionnels comportent chacun une carcasse annulaire cylindrique et une plaque porte-charbons. Ces deux éléments sont fixés sur un socle appartenant par exemple à une structure de liaison notamment avec le dispositif d'essuyage. Afin d'avoir un bon fonctionnement du moteur, l'axe de commutation défini par les charbons doit être positionné angulairement avec précision par rapport l'axe magnétique de la carcasse.Conventional motors each have a cylindrical annular carcass and a carbon plate. These two elements are fixed on a base belonging for example to a connection structure in particular with the wiping device. In order to have a good functioning of the motor, the switching axis defined by the coals must be positioned angularly with precision relative to the magnetic axis of the carcass.
Le montage de la carcasse sur le socle est actuellement réalisé par sertissage, ou par vissage.The mounting of the carcass on the base is currently carried out by crimping, or by screwing.
Le sertissage permet un montage indémontable des deux pièces, cependant, il ne permet pas de positionner la carcasse par rapport à la plaque porte-charbons avec suffisamment de précision. Le montage par vissage consiste soit à utiliser des tirants entre la carcasse et le socle, soit à visser des oreilles aménagées sur la carcasse avec des oreilles du socle. Ces deux modes de fixation sont tous les deux coûteux car ils nécessitent des aménagements particuliers de chaque pièce, et ils accroissent le temps de montage total de la machine.The crimping allows a non-removable mounting of the two parts, however, it does not allow the carcass to be positioned relative to the brush holder plate with sufficient precision. The assembly by screwing consists either in using tie rods between the carcass and the base, or in screwing ears fitted on the carcass with ears of the base. These two methods of attachment are both expensive since they require special arrangements for each part, and they increase the total assembly time of the machine.
Il est en outre connu des documents US 3 745 393 et GB 216 370 de prévoir un socle sur une première face transversale duquel la plaque porte-charbons est fixée, et sur une seconde face transversale duquel la carcasse est fixée, et en ce que le socle comporte des moyens pour positionner angulairement la carcasse par rapport à la plaque porte-charbons par coopération de formes complémentaires.It is further known from documents US Pat. No. 3,745,393 and GB 216,370 to provide a base on a first transverse face from which the carbon holder plate is fixed, and on a second transverse face from which the carcass is fixed, and in that the base includes means for angularly positioning the carcass relative to the brush holder plate by cooperation of complementary shapes.
Cependant les moyens de positionnement prévus dans ces documents n'assurent pas un positionnement angulaire précis de la carcasse par rapport à la plaque porte-charbons.However, the positioning means provided in these documents do not ensure precise angular positioning of the carcass relative to the carbon brush plate.
L'invention a pour but de proposer un montage de la carcasse sur le support qui permette de positionner angulairement la carcasse par rapport à la plaque porte-charbons avec précision, et indépendamment des moyens de fixation de la carcasse sur le socle.The object of the invention is to propose a mounting of the carcass on the support which allows the carcass to be angularly positioned relative to the carbon holder plate, and independently of the means for fixing the carcass to the base.
Dans ce but, l'invention propose une machine électrique tournante du type décrit précédemment, caractérisée en ce que les moyens de positionnement consistent en une combinaison de premiers moyens de positionnement entre le socle et la plaque et de deuxièmes moyens de positionnement entre le socle et la carcasse.To this end, the invention provides a rotary electrical machine of the type described above, characterized in that the positioning means consist of a combination of first positioning means between the base and the plate and second positioning means between the base and the carcass.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the description which follows, identical, similar or analogous elements will be designated by the same reference numbers.
On a représenté à la figure 1 une machine tournante électrique 10, ici un moteur utilisé pour l'entraînement d'un mécanisme d'essuyage conventionnel (non représenté). Le moteur 10 comporte un rotor (non représenté) qui tourne autour d'un axe A longitudinal de rotation, et un stator (non représenté) monté à l'intérieur d'une carcasse ou chemise statorique 12.FIG. 1 shows an electric rotary machine 10, here a motor used for driving a conventional wiping mechanism (not shown). The motor 10 comprises a rotor (not shown) which rotates around a longitudinal axis A of rotation, and a stator (not shown) mounted inside a carcass or stator jacket 12.
Le rotor porte à son extrémité axiale arrière un collecteur (non représenté) qui est alimenté électriquement par des charbons (non représentés). Pour garantir un contact constant entre les charbons (non représentés) et le collecteur, ceux-ci sont montés sur des balais (non représentés) qui s'étendent radialement dans un plan transversal perpendiculaire à l'axe de rotation du rotor.The rotor carries at its rear axial end a collector (not shown) which is electrically powered by coals (not shown). To guarantee constant contact between the coals (not shown) and the collector, these are mounted on brushes (not shown) which extend radially in a transverse plane perpendicular to the axis of rotation of the rotor.
Les balais sont aptes à coulisser radialement par rapport au rotor et ils sont guidés en coulissement par des moyens de guidage 14 fixés sur une plaque dite "porte-charbons" 16 qui comporte aussi des moyens (non représentés) pour l'alimentation électrique des charbons.The brushes are capable of sliding radially with respect to the rotor and they are guided in sliding by guide means 14 fixed on a plate called "carbon holder" 16 which also includes means (not shown) for the electrical supply of the coals.
La carcasse 12 est un élément cylind rique annulaire de section circulaire qui est coaxial au rotor. Elle est fermée à son extrémité axiale avant 18, et elle comporte en son centre un renflement 20 qui s'étend vers l'avant qui porte en son centre un palier de guidage en rotation du rotor (non représenté).The carcass 12 is an annular cylindrical element of circular section which is coaxial with the rotor. It is closed at its front axial end 18, and it has at its center a bulge 20 which extends forward which carries in its center a bearing for guiding the rotor in rotation (not shown).
Le moteur 1 0 comporte aussi un socle 22 qui reçoit sur une première face transversale arrière 24 la plaque porte-charbons 16 et qui reçoit sur une seconde face transversale avant 26 la carcasse 12. Les deux faces sont décalées axialement et la première face 24 est disposée en arrière de la seconde face 26 et elles délimitent un logement cylindrique 28 de section circulaire coaxial au rotor, et de longueur sensiblement égale à la longueur du collecteur du rotor.The motor 1 0 also includes a base 22 which receives on a first rear transverse face 24 the carbon holder plate 16 and which receives on a second front transverse face 26 the carcass 12. The two faces are axially offset and the first face 24 is disposed behind the second face 26 and they define a cylindrical housing 28 of circular section coaxial with the rotor, and of length substantially equal to the length of the rotor collector.
Le centre 48 de la première face 24 est ouvert et il reçoit un palier (non représenté) de guidage en rotation du rotor.The center 48 of the first face 24 is open and it receives a bearing (not shown) for guiding the rotor in rotation.
La première face arrière 24 et la plaque porte-charbons 16 sont circulaires et de même diamètre égal au diamètre intérieur du logement 28, permettant ainsi le centrage de la plaque porte- charbons 16 par rapport à l'axe A de rotation du rotor. La seconde face 26 est annulaire et s'étend radialement vers l'extérieur à partir de l'extrémité axiale avant du logement 28.The first rear face 24 and the carbon holder plate 16 are circular and of the same diameter equal to the inside diameter of the housing 28, thus allowing the centering of the carbon holder plate 16 relative to the axis A of rotation of the rotor. The second face 26 is annular and extends radially outwards from the front axial end of the housing 28.
Le socle 22 comporte une portée 30 annulaire cylindrique qui s'étend axialement vers l'avant depuis la face transversale avant 26 de sorte à prolonger le logement 28 au-delà de la seconde face transversale 26.The base 22 has a cylindrical annular surface 30 which extends axially forwards from the front transverse face 26 so as to extend the housing 28 beyond the second transverse face 26.
La face cylindrique extérieure 32 convexe de la portée 30 est reçue dans un logement cylindrique concave 33 de la carcasse 12 pour la fixation de la carcasse 12 sur le socle 22.The convex outer cylindrical face 32 of the bearing surface 30 is received in a concave cylindrical housing 33 of the carcass 12 for fixing the carcass 12 to the base 22.
Pour que le moteur 10 fonctionne avec un meilleur rendement, il faut que son axe de commutation, défini par les charbons, soit positionné angulairement le plus précisément possible par rapport à l'axe magnétique du stator, défini par la carcasse 12.For the motor 10 to operate with better efficiency, its switching axis, defined by the coals, must be angularly positioned most precisely possible with respect to the magnetic axis of the stator, defined by the casing 12.
Ainsi, le montage de la carcasse 12 par rapport à la plaque porte-charbons 16 doit être effectué avec un positionnement angulaire précis.Thus, the mounting of the carcass 12 relative to the carbon holder plate 16 must be carried out with precise angular positioning.
Pour cela, et conformément aux enseignements de l'invention, le socle 22 comporte des moyens pour positionner angulairement la carcasse 12 par rapport à la plaque porte- charbons 16. Le socle 22 comporte tout d'abord deux doigts d'indexationFor this, and in accordance with the teachings of the invention, the base 22 comprises means for angularly positioning the carcass 12 relative to the carbon holder plate 16. The base 22 firstly comprises two indexing fingers
32 qui coopèrent chacun avec une encoche 36 complémentaire de la plaque porte-charbons 16, comme on l'a représenté aux figures 2 et 4.32 which each cooperate with a notch 36 complementary to the carbon holder plate 16, as shown in FIGS. 2 and 4.
Chaque doigt 34 consiste ici en une nervure qui s'étend longitudinalement vers l'avant depuis la première face 24 du socle, et qui s'étend rad ialement vers l'intérieur depuis la paroi longitudinale intérieure concave du logement 28. De plus, le doigt 34 a la forme d'un triangle dont la base est sur la première face 24 du socle 22, et le sommet est au niveau de l'extrémité axiale avant du logement 28.Each finger 34 here consists of a rib which extends longitudinally forwards from the first face 24 of the base, and which extends radially inwards from the concave inner longitudinal wall of the housing 28. In addition, the finger 34 has the shape of a triangle, the base of which is on the first face 24 of the base 22, and the apex is at the level of the front axial end of the housing 28.
Selon un mode de réalisation préféré de l'invention, les deux doigts 34 sont diamétralement opposés et symétriques par rapport à l'axe A de rotation du rotor, de sorte à définir un plan axial P1 d'indexation . Comme on l'a représenté aux figures 2 et 3, le socle 22 comporte aussi un pion d'indexation 38 qui coopère avec un cran 40 complémentaire de la carcasse 12.According to a preferred embodiment of the invention, the two fingers 34 are diametrically opposite and symmetrical with respect to the axis A of rotation of the rotor, so as to define an axial plane P1 of indexing. As shown in FIGS. 2 and 3, the base 22 also includes an indexing pin 38 which cooperates with a notch 40 complementary to the carcass 12.
Le pion 38 s'étend axialement vers l'avant depuis la seconde face transversale 26. Il est ainsi disposé radialement à l'extérieur de la portée 30. De plus, selon un mode de réalisation préféré de l'invention, le pion 38 est disposé dans le plan axial P1 d'indexation.The pin 38 extends axially forward from the second transverse face 26. It is thus arranged radially outside of the bearing surface 30. In addition, according to a preferred embodiment of the invention, the pin 38 is arranged in the axial plane P1 of indexing.
L'extrémité axiale arrière ouverte de la carcasse 12 comporte une collerette annulaire 42 qui s'étend radialement vers l'extérieur et dans laquelle est formé le cran 40. La face transversale annulaire arrière 44 de la collerette 42 est en appui axial contre la seconde face transversale 26 du socle 22, permettant ainsi d'assurer un parallélisme des axes de la carcasse 12 et de la plaque porte-charbons 16.The open rear axial end of the carcass 12 has an annular flange 42 which extends radially towards the outside and in which the notch 40 is formed. The rear annular transverse face 44 of the flange 42 is in axial abutment against the second transverse face 26 of the base 22, thus making it possible to ensure parallelism of the axes of the carcass 12 and of the brush holder plate 16.
Pour assurer le positionnement ou indexation angulaire de la carcasse 12 par rapport à la plaque porte-charbons 16, les encoches 36 sont positionnées angulairement par rapport aux charbons de sorte à former un angle déterminé avec l'axe de commutation du moteur 10.To ensure the angular positioning or indexing of the carcass 12 relative to the carbon brush plate 16, the notches 36 are angularly positioned relative to the carbon brushes so as to form a determined angle with the switching axis of the motor 10.
De la même manière, le cran 40 est positionné angulairement sur la collerette 42 de sorte à être disposé dans un second plan axial P2 qui forme le même angle avec l'axe magnétique de la carcasse 12. Puisque le pion 38 et les doigts 34 sont disposés dans un même plan axial P1 , l'égalité entre l'angle entre les encoches 36 et l'axe de commutation et l'angle entre le second plan axial P2 et l'axe magnétique de la carcasse 12 permet par exemple d'obtenir un positionnement angulaire précis de la carcasse 12 par rapport à la plaque porte-charbons 16.Similarly, the notch 40 is angularly positioned on the flange 42 so as to be disposed in a second axial plane P2 which forms the same angle with the magnetic axis of the carcass 12. Since the pin 38 and the fingers 34 are arranged in the same axial plane P1, the equality between the angle between the notches 36 and the switching axis and the angle between the second axial plane P2 and the magnetic axis of the carcass 12 makes it possible for example to obtain precise angular positioning of the carcass 12 relative to the carbon holder plate 16.
De ce fait, la précision du positionnement angulaire des deux éléments est indépendante des moyens de fixation de la carcasse 12 sur le socle 22.As a result, the precision of the angular positioning of the two elements is independent of the means for fixing the carcass 12 to the base 22.
De préférence, la carcasse 12 est fixée au socle 22 par l'intermédiaire d'une bague de tolérance 46 interposée entre la portée 30 et le logement 33 de la carcasse 12.Preferably, the carcass 12 is fixed to the base 22 by means of a tolerance ring 46 interposed between the bearing surface 30 and the housing 33 of the carcass 12.
La bague de tolérance 46 est généralement constituée d'une bande ondulée en feuillard d'acier pour ressort, par exemple du type commercialisé par la société RENCOL. Les dimensions de la bague de tolérance 46 , notamment sa longueur "L" et son épaisseur "e" (figure 1 ), sont déterminées pour assurer la fixation de la carcasse 12 sur le socle 22 en fonction des efforts subis. La bague de tolérance 46 est disposée radialement vers l'intérieur par rapport à la collerette 42 et le pion 38, ce qui permet, lors du montage, de positionner angulairement la carcasse 12 par rapport au socle 22 sans être gêné par les moyens de fixation de la carcasse 12 constitués par la bague de tolérance 46.The tolerance ring 46 generally consists of a corrugated strip of steel strip for a spring, for example of the type sold by the company RENCOL. The dimensions of the tolerance ring 46, in particular its length "L" and its thickness "e" (Figure 1), are determined to ensure the fixing of the carcass 12 on the base 22 according to the forces undergone. The tolerance ring 46 is arranged radially inwards relative to the collar 42 and the pin 38, which allows, during assembly, to angularly position the carcass 12 relative to the base 22 without being hindered by the fixing means of the carcass 12 formed by the tolerance ring 46.
L'utilisation de la bague de tolérance 46 permet d'augmenter les tolérances de fabrication de la porté 30 et du logement 33 de la carcasse 12. En effet, la bague de tolérance 46 autorise un certain défaut de coaxialité entre la carcasse 12 et la portée 30. Le centrage de la carcasse 12 est obtenu au montage par l'intermédiaire des différents paliers de guidage du rotor montés au centre de la première face transversale 24, et dans le renflement 20. Pour le montage de la carcasse 12 sur le socle 22, on monte d'abord le bague de tolérance 46 sur la face cylindrique extérieure 32 de la portée 30. Ensuite, le socle est emboîté dans la carcasse de sorte que la bague de tolérance 46 se loge dans le logement 33 de la carcasse 12, jusqu'à ce que la face avant 26 du socle 22 vienne en butée axiale contre la face transversale arrière de la collerette 42.The use of the tolerance ring 46 makes it possible to increase the manufacturing tolerances of the bearing 30 and of the housing 33 of the carcass 12. In fact, the tolerance ring 46 allows a certain lack of coaxiality between the carcass 12 and the range 30. The centering of the carcass 12 is obtained during assembly by means of the various guide bearings of the rotor mounted at the center of the first transverse face 24, and in the bulge 20. For the mounting of the carcass 12 on the base 22, the tolerance ring 46 is first mounted on the outer cylindrical face 32 of the bearing surface 30. Then, the base is fitted into the carcass so that the tolerance ring 46 is housed in the housing 33 of the carcass 12 , until the front face 26 of the base 22 comes into axial abutment against the rear transverse face of the flange 42.
Selon une variante de l'invention (non représentée), la fixation de la carcasse 12 sur le socle 22, est réalisée par l'intermédiaire de plusieurs bagues de tolérance 46. Selon un mode préféré de cette variante, les bagues de tolérance 46 sont d'épaisseurs croissantes, en se rapprochant de la seconde face transversale 26 su socle, ce qui permet de faciliter le montage et la fixation de la carcasse 12, tout en améliorant sa fixation sur le socle 22. L'étanchéité du montage est obtenue au moyen d'un joint torique ou à lèvre (non représenté) qui est interposé entre la portée 30 et la carcasse 12. L'épaisseur de la bague de tolérance permet de disposer d'un espace entre la carcasse 12 et la portée 30, à l'intérieur duquel il est possible de loger le joint. Il n'est alors plus nécessaire d'usiner une de ces deux pièces pour réaliser un logement pour le joint qui est comprimé axialement à l'issue du montage.According to a variant of the invention (not shown), the fixing of the carcass 12 to the base 22 is carried out by means of several tolerance rings 46. According to a preferred embodiment of this variant, the tolerance rings 46 are increasing thicknesses, approaching the second transverse face 26 of the base, which makes it easier to assemble and fix the carcass 12, while improving its attachment to the base 22. The seal of the assembly is obtained at by means of an O-ring or lip seal (not shown) which is interposed between the bearing surface 30 and the carcass 12. The thickness of the tolerance ring makes it possible to have a space between the carcass 12 and the bearing surface 30, inside of which it is possible to house the seal. It is not then no longer necessary to machine one of these two parts to produce a housing for the seal which is compressed axially at the end of the assembly.
Il sera aussi compris que des inversions mécaniques simples peuvent constituer des variantes de réalisation de l'invention. Par exemple, la portée 30 peut être de diamètre supérieur, et la première face 24 et la seconde face 26 du socleIt will also be understood that simple mechanical inversions can constitute alternative embodiments of the invention. For example, the bearing surface 30 may be of greater diameter, and the first face 24 and the second face 26 of the base
22 peuvent être situées dans un même plan transversal.22 can be located in the same transverse plane.
De même, les doigts 34 et les encoches 36 peuvent définir un plan P1 décalé angulairement par rapport au plan P2 défini par le pion et le cran, l'angle formé entre ces deux plans étant connu.Similarly, the fingers 34 and the notches 36 can define a plane P1 angularly offset from the plane P2 defined by the pin and the notch, the angle formed between these two planes being known.
L'invention permet donc un montage précis du stator d'un moteur électrique par rapport à la plaque porte-charbons permettant ainsi d'améliorer le rendement du moteur. De plus, l'utilisation d'une bague de tolérance permet de réduire les usinages nécessaires pour le montage de la carcasse sur le socle, réduisant de ce fait les coûts de fabrication. The invention therefore allows precise mounting of the stator of an electric motor relative to the brush holder plate, thereby improving the efficiency of the motor. In addition, the use of a tolerance ring makes it possible to reduce the machining operations necessary for mounting the carcass on the base, thereby reducing manufacturing costs.
