Avantageusement, le câble (13) peut être mis en arc de cercle dans ladite zone moins large du carter. On peut prévoir que le câble peut s'enrouler sur une bordure interne (14) formée sur le diamètre intérieur du carter, ou même former une hélice grâce à un évidement (12) prévu dans la partie large (8) du carter.The housing (8) of the sensor (7) has at least one zone of narrower width than the rest, and the connection cable (13) comes out of the widest part of this housing, in a tangential direction relative to the bearing. . Advantageously, the cable (13) can be placed in an arc in said narrower zone of the casing. It can be provided that the cable can be wound on an internal border (14) formed on the inside diameter of the casing, or even form a helix thanks to a recess (12) provided in the wide part (8) of the casing.
Description
L'invention concerne un roulement comportant un capteur et plusThe invention relates to a bearing comprising a sensor and more.
précisément un roulement comportant un capteur destiné à contrôler les conditions de fonctionnement de ce roulement, ce capteur étant disposé dans un carter de capteur, lui-même placé séparément à côté du roulement ou intégré dans celui-ci, et les signaux de sortie du capteur étant dirigés sur un dispositif d'interprétation, par l'intermédiaire d'un câble de raccordement. Des roulements comportant des capteurs sont connus depuis de nombreuses années (voir, par exemple, les precisely a bearing comprising a sensor intended to control the operating conditions of this bearing, this sensor being disposed in a sensor casing, itself placed separately next to the bearing or integrated in it, and the sensor output signals being directed on an interpretation device, via a connection cable. Bearings with sensors have been known for many years (see, for example,
documents EP-05 53 716 Ai ou DE-A- 19 11 513). documents EP-05 53 716 Ai or DE-A- 19 11 513).
Le capteur est, en règle générale, disposé The sensor is, as a rule, arranged
latéralement, contre la bague extérieure fixe du roulement. laterally, against the fixed outer ring of the bearing.
Le câble sort du roulement en direction axiale ou radiale. The cable leaves the bearing in the axial or radial direction.
De nombreuses structures de l'entourage permettent un tel passage de câble. Mais, comme la plupart du temps, le volume d'implantation est étroitement limité en direction axiale et radiale, on ne peut pas, dans beaucoup de cas, Many surrounding structures allow such a cable passage. But, as most of the time, the implantation volume is tightly limited in axial and radial direction, one cannot, in many cases,
installer sans difficulté de tels roulements à capteurs. install such sensor bearings without difficulty.
Dans le cas de tels volumes d'implantation, on doit fortement replier le câble, ce qui conduit facilement à des points de cisaillement et à des ruptures de câble. De plus, le roulement doit être monté dans une position déterminée, afin que le câble puisse en sortir sans devoir être enroulé autour de l'arbre, avec un risque de frotter sur l'arbre In the case of such installation volumes, the cable must be strongly folded back, which easily leads to shear points and cable breaks. In addition, the bearing must be mounted in a determined position, so that the cable can come out without having to be wrapped around the shaft, with a risk of rubbing on the shaft.
en rotation.in rotation.
Dans le cas de câbles s'éloignant axialement, il se pose, en plus, le problème que, dans le cas de ce montage, il ne peut y avoir, en direction axiale, aucune In the case of cables moving away axially, there is also the problem that, in the case of this mounting, there can be, in the axial direction, no
compensation de longueur.length compensation.
Le but de l'invention est donc d'améliorer un roulement du type décrit au début, comportant un capteur, de telle façon qu'il puiss être installé de façon universelle, même dans le cas d'un volume d'implantation étroit radialement et/ou axialement, qu'il n'impose pas un faible rayon de courbure au câble de raccordement, qu'il évite, de façon sûre, tout contact entre le câble de raccordement et les pièces tournantes voisines, et permette The object of the invention is therefore to improve a bearing of the type described at the start, comprising a sensor, in such a way that it can be installed universally, even in the case of a radially narrow installation volume and / or axially, that it does not impose a small radius of curvature on the connection cable, that it safely avoids any contact between the connection cable and the neighboring rotating parts, and allows
une compensation de longueur du câble de raccordement. length compensation of the connection cable.
La solution du problème est donnée, selon l'invention, en prévoyant que le carter de capteur présente, au moins le long d'une zone, une largeur plus faible que le reste, et que le câble de raccordement du capteur sort de la partie plus large du carter de capteur, en suivant une The solution to the problem is given, according to the invention, by providing that the sensor casing has, at least along one zone, a narrower width than the rest, and that the connection cable of the sensor leaves the part wider of the sensor housing, following a
direction tangentielle par rapport au roulement. tangential direction with respect to the bearing.
Avantageusement le câble de raccordement peut être mis Advantageously the connection cable can be laid
en arc de cercle, dans la zone la plus étroite du capteur. in an arc, in the narrowest area of the sensor.
Dans ce cas, de préférence, le carter de capteur présente axialement, sur son diamètre intérieur, une bordure, ou des segments de bordure, sur lesquels le câble In this case, preferably, the sensor casing has axially, on its internal diameter, an edge, or edge segments, on which the cable
de raccordement peut s'enrouler.connection can be rolled up.
De façon intéressante, on prévoit alors que le carter de capteur, dans sa zone large, présente un évidement dans lequel, en coordination avec la bordure, on peut déposer Interestingly, provision is then made for the sensor housing, in its wide area, to have a recess in which, in coordination with the edge, it is possible to deposit
en hélice le câble de raccordement. helical connection cable.
Le carter de capteur est réalisé de façon à présenter, sur au moins un segment circulaire, une largeur plus faible. On fait sortir le câble de raccordement du capteur de la partie la plus large du carter de capteur, dans la direction de la tangente au roulement. Il n'est pas alors obligatoire que le câble de raccordement s'éloigne aussitôt radialement ou axialement, mais, au contraire, on peut le disposer en arc de cercle dans la zone plus étroite du carter du capteur, sans que cela provoque un élargissement The sensor housing is made so as to have, on at least one circular segment, a smaller width. The sensor connection cable is taken out of the widest part of the sensor housing, in the direction of the tangent to the bearing. It is not then obligatory for the connection cable to immediately move away radially or axially, but, on the contrary, it can be arranged in an arc of a circle in the narrower area of the sensor housing, without this causing widening.
de l'ensemble du système.of the whole system.
Dans une forme d'exécution préférée, sur le diamètre intérieur, est réalisée, en plus, dans la zone libre du câble, une bordure, ou des segments de bordure. Cela empêche que l'arc de câble déposé le long du capteur frotte sur des pièces qui tournent avec la bague intérieure tournante du roulement. Si le câble de raccordement est guidé d'abord en s'enroulant en arc de cercle autour de l'arbre, le frottement de la spire sur la bordure, ou sur les segments de bordure, produit une réduction de l'effet de traction du raccordement du câble au capteur, ce qui augmente, de plus, la sécurité de fonctionnement du capteur. Egalement, l'arc du câble permet de compenser des coulissements axiaux entre le capteur et la structure In a preferred embodiment, on the inside diameter, is made, in addition, in the free area of the cable, an edge, or edge segments. This prevents the cable arc deposited along the sensor from rubbing against parts that rotate with the rotating inner ring of the bearing. If the connection cable is first guided by winding in an arc around the shaft, the friction of the coil on the edge, or on the edge segments, produces a reduction in the traction effect of the connection of the cable to the sensor, which further increases the operational safety of the sensor. Also, the arc of the cable makes it possible to compensate for axial sliding between the sensor and the structure
environnante lors du montage et en fonctionnement. surrounding during assembly and operation.
Selon une autre forme d'exécution, dans la zone plus large du carter de capteur, il est prévu un évidement permettant un enroulement en hélice du câble de raccordement à côté du roulement, sans conduire à un élargissement de l'ensemble du système. Cela améliore encore plus la diminution de l'effet de traction et la According to another embodiment, a recess is provided in the wider area of the sensor housing allowing helical winding of the connection cable next to the bearing, without leading to an enlargement of the whole system. This further improves the decrease in the pulling effect and the
possibilité de compensation axiale de la longueur. possibility of axial length compensation.
On décrira ci-après l'invention sur un exemple The invention will be described below on an example
d'exécution.of execution.
La figure 1 est une vue en coupe d'un roulement selon l'invention. La figure 2 est une vue de profil, d'un roulement Figure 1 is a sectional view of a bearing according to the invention. Figure 2 is a side view of a bearing
selon l'invention.according to the invention.
Sur la figure 1, on a désigné par 1 la bague intérieure du roulement, par 2 les corps de roulement, par 3 la cage, par 4 la bague extérieure, par 5 le joint d'étanchéité, et par 6 le générateur d'impulsions. En face du générateur d'impulsions 6, se trouve un capteur 7, qui In FIG. 1, the inner ring of the bearing is designated by 1, the bearing bodies by 2, the cage by 3, the outer ring by 4, by 5 the seal, and by 6 the pulse generator . In front of the pulse generator 6 is a sensor 7, which
est disposé dans un carter de capteur 8. is arranged in a sensor housing 8.
Le carter de capteur 8 est, par exemple, encliqueté, au moyen d'une saillie périphérique 9, dans une rainure 10, The sensor casing 8 is, for example, engaged, by means of a peripheral projection 9, in a groove 10,
réalisée dans l'alésage de la bague extérieure. made in the bore of the outer ring.
Comme il ressort de la figure 2, le carter de capteur 8 a, sur au moins une zone 11, une largeur plus faible et il présente un évidement 12 dans lequel passe le câble de raccordement 13. Le câble de raccordement 13 sort tangentiellement du carter de capteur 8 et est enroulé sur une bordure 14, évitant ainsi un contact avec des pièces As can be seen from FIG. 2, the sensor casing 8 has, over at least one zone 11, a narrower width and it has a recess 12 through which the connection cable 13 passes. The connection cable 13 tangentially exits the housing sensor 8 and is wound on a border 14, thus avoiding contact with parts
