Description

ROULEMENT A CAPTEUR D'INFORMATIONS.BEARING WITH INFORMATION SENSOR.

L'invention concerne un roulement à capteur d'informations qui comprend une bague fixe et une bague tournante présentant des chemins de roulement pour des corps roulants disposés dans une cage de retenue et de positionnement angulaire desdits corps.The invention relates to an information sensor bearing which comprises a fixed ring and a rotating ring having raceways for rolling bodies arranged in a cage for retaining and angular positioning of said bodies.

Les mécanismes constitutifs par exemple des robots industriels, des boîtes de vitesses, variateurs ou ralentisseurs utilisent des roulements à corps roulants qui assurent avec précision la rotation de certains organes de ces mécanismes. Le contrôle-du mouvement de ces organes nécessite des dispositifs extérieurs mécaniques, pneumatiques, électriques ou électroniques qui mesurent notamment une vitesse de rotation et sa variation.The constituent mechanisms, for example industrial robots, gearboxes, variators or retarders use rolling body bearings which precisely ensure the rotation of certain members of these mechanisms. The control of the movement of these organs requires external mechanical, pneumatic, electric or electronic devices which in particular measure a speed of rotation and its variation.

La publication FR-A- 1 604 461 décrit un dispositif d'exploration de la vitesse entreWdeux élements en rotation relative qui utilise des pôles tournants et une bobine rendant possible le changement de flux dans le circuit magnétique de la bobine. Ce dispositif est difficilement adaptable à un roulement.The publication FR-A-1 604 461 describes a device for exploring the speed between two elements in relative rotation which uses rotating poles and a coil making it possible to change the flux in the magnetic circuit of the coil. This device is difficult to adapt to a bearing.

La publication FR-A- 2 267 476 décrit un palier à roulement avec détecteur d'usure à capteur disposé entre les bagues extérieure et intérieure du roulement qui est relié à un dispositif de signalisation.The publication FR-A-2 267 476 describes a rolling bearing with wear sensor sensor disposed between the outer and inner rings of the bearing which is connected to a signaling device.

Le problème à la base de l'invention réside en la recherche d'un dispositif de montage du capteur d'informations sur un roulement qui ne nécessite aucune modification du roulement pour l'adaptation du capteur. The problem underlying the invention lies in the search for a device for mounting the information sensor on a bearing which does not require any modification of the bearing for the adaptation of the sensor.

L'invention a également pour objet un roulement associé à un capteur fixé à la bague fixe du roulement devant lequel tourne un anneau codeur fixé à un élément tournant du roulement.The invention also relates to a bearing associated with a sensor fixed to the fixed ring of the bearing in front of which rotates an encoder ring fixed to a rotating element of the bearing.

Conformément à l'invention, le problème est résolu en ce que la bague fixe du roulement possède une portée de montage du capteur tandis qu'au moins la bague tournante possède une surface de retenue d'un élément codeur disposé en vis-à-vis du capteur.According to the invention, the problem is solved in that the fixed ring of the bearing has a mounting surface for the sensor while at least the rotating ring has a retaining surface of an encoder element arranged opposite. of the sensor.

Selon le mode de réalisation préférentiel de l'invention, les portées de montage du capteur et les surfaces de retenue de l'élément codeur sont constituées par les portées et les gorges de montage des disposés tifs d'étanchéité du roulement.According to the preferred embodiment of the invention, the mounting surfaces of the sensor and the retaining surfaces of the encoder element are constituted by the mounting surfaces and grooves of the sealing elements arranged in the bearing.

D'autres objets et avantages de l'invention ressortiront de la description qui va suivre faite en référence au dessin annexé dans lequei - la figure 1 est une vue en élévation d'une partie du

bearing - Figure 2 is an axial sectional view of the bearing
shown in Figure 1, along line 2-2 thereof - Figures 3 to 7 show views in axial section of the bearing relating to mounting variants of the sensor - Figures 8, 9 show views in axial section

cation of the invention.

En référencedesfigures 1, 2, le roulement représenté possède une bague extérieure 1 et une bague intérieure 2 susceptibles d'être au choix fixe ou tournante en fonction du montage utilisé. With reference to Figures 1, 2, the bearing shown has an outer ring 1 and an inner ring 2 which can be either fixed or rotating depending on the assembly used.

Les bagues 1 et 2 possèdent des chemins de roulement pour des corps roulants 3 disposés dans une cage 4 qui en assure la retenue et le positionnement angulaire.The rings 1 and 2 have raceways for rolling bodies 3 arranged in a cage 4 which ensures their retention and angular positioning.

Un moyen d'étanchéité 5 est constitué par un anneau 6 monté dans une gorge 11 qui porte des lèpres d'étanchéité 7, 7' en appui axial et radial. L'anneau 6 est solidaire de la bague extérieure l-supposée montée tournante par rapport à l'autre bague 2. Les Ièvres d'étanchéité 7, 7' sont en appui sur une surface d'étanchéité 8 portée par exemple par un déflecteur 9 solidaire de la bague intérieure 2.A sealing means 5 is constituted by a ring 6 mounted in a groove 11 which carries sealing lips 7, 7 ′ in axial and radial support. The ring 6 is integral with the outer ring l-supposed to be rotatably mounted relative to the other ring 2. The sealing lips 7, 7 ′ are supported on a sealing surface 8 carried for example by a deflector 9 secured to the inner ring 2.

Selon l'invention, l'une des faces latérales du roulement possède une portée de montage d'un capteur 10 solidarisé avec la bague fixe 2 par emmanchement ou par élasticité. Le capteur 10 peut être formé à titre d'exemple par un condensateur ou par une bobine et directement monté sur la bague non tournante 2 comme représenté aux figures 5 et 6 ou rendu solidaire du déflecteur 9 comme représenté auxwfigures 2, 3, 4, 7.According to the invention, one of the lateral faces of the bearing has a mounting surface for a sensor 10 secured to the fixed ring 2 by fitting or by elasticity. The sensor 10 can be formed by way of example by a capacitor or by a coil and directly mounted on the non-rotating ring 2 as shown in FIGS. 5 and 6 or made integral with the deflector 9 as shown in FIGS. 2, 3, 4, 7 .

La bague tournante 1 porte une surface de retenue réalisée par une gorge 11 comme représenté sur les figures 3, 6 ou une portée 12 comme représenté sur les figures 2, 4,5,7. La gorge 11 et la portée 12 assurent le maintien d'un disque codeur 13 qui s'étend radialement devant le capteur 10 et qui peut être une partie intégrante de l'anneau 6.The rotating ring 1 carries a retaining surface produced by a groove 11 as shown in Figures 3, 6 or a bearing 12 as shown in Figures 2, 4,5,7. The groove 11 and the bearing surface 12 maintain an encoder disc 13 which extends radially in front of the sensor 10 and which can be an integral part of the ring 6.

Le disque codeur 13 est situé à une distance appropriée du capteur 10 et porte des graduations magnétiques 14 angulairement espacées à la périphérie du disque qui sont montées à défilement devant le capteur correspondant 10 au cours de la rotation de la bague tournante 1. The encoder disc 13 is located at an appropriate distance from the sensor 10 and carries magnetic graduations 14 angularly spaced at the periphery of the disc which are mounted to scroll in front of the corresponding sensor 10 during the rotation of the rotating ring 1.

Selon un mode de réalisation, le disque 13 porte des ouvertures de passage du lubrifiant.According to one embodiment, the disc 13 carries openings for the passage of the lubricant.

Lors de la rotation du disque 13 devant-le capteur 10, un signal électrique alternatif est généré en fonction de la vitesse et du pas de la graduation 14. Des sorties de fils sont ménagées dans la partie fixe du roulement afin de pouvoir transmettre et traiter les informations électriques qui donneront la vitesse relative des deux bagues de roulements.When the disc 13 rotates in front of the sensor 10, an alternating electrical signal is generated as a function of the speed and the pitch of the graduation 14. Wire outlets are provided in the fixed part of the bearing in order to be able to transmit and process the electrical information which will give the relative speed of the two bearing rings.

Le comptage des impulsions pendant un temps donné permet de la sorte la mesure de la vitesse ainsi qu'une mesure de la position angulaire de la bague tournante 1 par rapport à la bague fixe 2.The counting of the pulses during a given time thus allows the measurement of the speed as well as a measurement of the angular position of the rotating ring 1 relative to the fixed ring 2.

Afin d'améliorer la précision de la mesure de position de la bague tournante, une deuxième graduation magnétique 14', coaxiale à la graduation 14, équipe le disque codeur et permet à l'aide d'un deuxième capteur un comptage plus précis à la manière d'un vernier. Les pas des graduations peuvent être divers comme montré à la figure 1 (côté gauche ). Les graduations 14, 14' de la figure 1 permettent un comptage binaire.In order to improve the accuracy of the measurement of the position of the rotating ring, a second magnetic graduation 14 ', coaxial with the graduation 14, equips the encoder disc and allows, using a second sensor, a more precise counting at the like a vernier. The steps of the graduations can be varied as shown in Figure 1 (left side). The graduations 14, 14 ′ in FIG. 1 allow binary counting.

Le nombre de graduations coaxiales du disque 13 codeur peut être supérieur à 2. La précision de la mesure de positionnement peut être accrue en fixant un disposés tif capteur important des éléments capables de générer des signaux de caractéristiques différentes, en lieu et place du deuxième joint ou déflecteur d'étanchéité du roulement. Cet autre dispositif, associé au premier, est capable après traitement des informations.The number of coaxial graduations of the encoder disc 13 can be greater than 2. The accuracy of the positioning measurement can be increased by fixing a large sensor arrangement of elements capable of generating signals of different characteristics, in place of the second seal. or bearing sealing deflector. This other device, associated with the first, is capable after processing the information.

de conférer à l'ensemble du système une très grande performance. Enfin, lé capteur et le disque codeur peuvent être entièrement intégrés à une cartouche joint d'étanchéité 15, 25 dans le but de réaliser un roulement étanche et graissé à vie comme représenté aux figures 7, 9.to give the whole system a very high performance. Finally, the sensor and the encoder disc can be fully integrated into a seal cartridge 15, 25 in order to produce a sealed bearing and greased for life as shown in FIGS. 7, 9.

Sans sortir du cadre de l'invention, il est bien entendu possible d'adapter le capteur aux butées axiales étant sous-entendu que l'élément codeur et -le support du capteur possèderont une configuration cylindrique.Without departing from the scope of the invention, it is of course possible to adapt the sensor to the axial stops, it being understood that the encoder element and the sensor support will have a cylindrical configuration.

Les figures 8, 9 décrivent des roulements à plusieurs capteurs d'informations qui permettent de déceler les mouvements relatifs de leurs divers composants par rapport au mouvement théorique de chacun d'eux dans le but de détecter les anomalies éventuelles de fonctionnement. Les capteurs permettent en particulier de procéder à la mesure de l'angle de contact des corps roulants avec leurs chemins de roulement ; mettre en évidence le glissement non désirés'd'un élément du roulement ; contrôler la précharge d'un ensemble mecanique monté associé à plusieurs roulements ; suivre l'évolution du jeu de fonctionnement du roulement détecter les premiers signes d'une détérioration des chemins de roulement ou des corps roulants.FIGS. 8, 9 describe bearings with several information sensors which make it possible to detect the relative movements of their various components with respect to the theoretical movement of each of them in order to detect possible operating anomalies. The sensors make it possible in particular to measure the contact angle of the rolling bodies with their raceways; highlight the unwanted sliding of a bearing element; check the preload of a mounted mechanical assembly associated with several bearings; follow the evolution of the bearing operating clearance detect the first signs of deterioration of the raceways or rolling bodies.

A cet effet, la bague fixe 2 du roulement possède une portée de montage d'un capteur 10 et d'un capteur additionnel 20 montés sur un même déflecteur 9 ou sur deux déflecteurs 9, 9' agencés de part et d'autre du roulement par rapport aux faces latérales opposées de la bague 2. L'élément codeur 13 disposé en vis-à-vis du capteur 10 est retenu par la bague tournante 1 et un élément codeur additionnel 23, disposé en vis-àvis du capteur 20, est porté par la cage 4 ou intégré à la matière constitutive de celle-ci. To this end, the fixed ring 2 of the bearing has a mounting range of a sensor 10 and an additional sensor 20 mounted on the same deflector 9 or on two deflectors 9, 9 'arranged on either side of the bearing. with respect to the opposite lateral faces of the ring 2. The encoder element 13 disposed opposite the sensor 10 is retained by the rotating ring 1 and an additional encoder element 23, disposed opposite the sensor 20, is carried by the cage 4 or integrated into the material constituting it.

Le deuxième ensemble capteur 20 - élément codeur 23 permet de déterminer la vitesse relative de la cage 4 par rapport à la bague fixe 2. The second sensor 20 - encoder element 23 assembly makes it possible to determine the relative speed of the cage 4 relative to the fixed ring 2.

Selon la figure 9, l'élément codeur 13 est perméable aux signaux émis par l'élément codeur 23 porté par la cage 4. A cet effet, l'élément 13 est formé par un anneau muni de fenêtres devant lesquelles défile l'élément codeur 23 et qui assurent un passage de lubrifiant. According to FIG. 9, the coding element 13 is permeable to the signals emitted by the coding element 23 carried by the cage 4. For this purpose, the element 13 is formed by a ring provided with windows in front of which the coding element scrolls. 23 and which provide a lubricant passage.
