io Ce type de dispositif emploie en général un grand nombre de pièces et a un fonctionnement qui est très sensible aux dispersions géométriques de ces pièces. En particulier, lorsque les arbres accouplés sont des arbres cannelés, les défauts géométriques d'orientation des cannelures peuvent entraîner des dysfonctionnements dans la transmission du mouvement (bruits, vibrations, corrosion excessive etc...). De plus, des défauts d'alignements (ou d'excentricité) entre les axes de rotation des arbres accouplés peuvent entraîner de mauvais fonctionnements dans la transmission du mouvement de rotation.  This type of device generally employs a large number of parts and has an operation which is very sensitive to the geometric dispersions of these parts. In particular, when the coupled shafts are splined shafts, the geometrical orientation defects of the splines can cause malfunctions in the transmission of the movement (noise, vibrations, excessive corrosion, etc.). In addition, misalignments (or eccentricity) between the axes of rotation of the coupled shafts can cause malfunctions in the transmission of the rotational movement.

L'invention concerne également des arbres tournants concentriques respectivement intérieur et extérieur, accouplés au moyen d'un dispositif d'accouplement, conforme à l'une quelconque des caractéristiques précédentes.  The invention also relates to concentric rotating shafts respectively inner and outer, coupled by means of a coupling device, according to any one of the preceding characteristics.

D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles: - la figure 1 représente une vue en perspective et partielle de deux arbres concentriques tournant destinés à être io accouplés, - les figures 2 et 3 représentent respectivement des vues en perspectives de deux éléments intermédiaires de liaison du dispositif d'accouplement selon l'invention, - la figure 4 représente une vue en coupe transversale 15 des deux arbres de la figure 1, accouplés au moyen d'un dispositif d'accouplement selon l'invention, - la figure 5 représente une vue en perspective et en coupe longitudinale partielle des arbres accouplés de la figure 4, dans laquelle les axes longitudinaux des deux arbres ne sont pas colinéaires, - la figure 5 représente une vue en coupe longitudinale de l'agencement de la figure 5.  Other particularities and advantages will appear on reading the description below, with reference to the figures in which: FIG. 1 represents a perspective and partial view of two concentric rotating shafts intended to be coupled, FIGS. 2 and 3 respectively represent perspective views of two intermediate connecting elements of the coupling device according to the invention; FIG. 4 represents a cross-sectional view of the two shafts of FIG. 1, coupled by means of a coupling device according to the invention, - Figure 5 shows a perspective view in partial longitudinal section of the coupled shafts of Figure 4, in which the longitudinal axes of the two shafts are not collinear, - Figure 5 shows a longitudinal sectional view of the arrangement of FIG.

Le dispositif d'accouplement selon l'invention va à présent être décrit dans un exemple d'application à deux arbres rotatifs concentriques cannelés (cf. figure 1).  The coupling device according to the invention will now be described in an example of application to two concentric rotating shafts (FIG. 1).

Un premier arbre dit intérieur 1 comporte des cannelures 101 longitudinales formées sur sa surface extérieure cylindrique. Les cannelures 101 sont dites longitudinales car parallèles à l'axe de symétrie longitudinal de l'arbre 1 (qui coïncide de préférence avec l'axe de rotation de l'arbre 1).  A first inner shaft 1 has longitudinal grooves 101 formed on its cylindrical outer surface. The grooves 101 are said to be longitudinal because parallel to the longitudinal axis of symmetry of the shaft 1 (which coincides preferably with the axis of rotation of the shaft 1).

Le deuxième arbre dit extérieur 2 est quant à lui de forme tubulaire et comprend également des cannelures 301 longitudinales formées sur sa surface cylindrique intérieure.  The second outer shaft 2 is itself of tubular shape and also comprises longitudinal grooves 301 formed on its inner cylindrical surface.

Le diamètre intérieur du second arbre 2 est supérieur au 5 diamètre extérieur du premier arbre 1, de façon à accueillir le dispositif d'accouplement entre les deux arbres 1, 2.  The inner diameter of the second shaft 2 is greater than the outer diameter of the first shaft 1, so as to receive the coupling device between the two shafts 1, 2.

Le dispositif d'accouplement comprend un premier élément 3 intermédiaire ayant la forme générale d'une bague cylindrique et destiné à être disposé concentriquement autour io premier arbre 1 (figure 2). La surface intérieure du premier élément 3 intermédiaire a un diamètre et des cannelures 103 adaptés pour s'engrener avec la surface extérieure du premier arbre 1. Le premier élément 3 intermédiaire présente une surface extérieure cylindrique lisse sur laquelle fait saillie quatre doigts 203 orientés radialement vers l'extérieur du corps de l'élément 3. Les quatre doigts 203 sont situés dans un même plan perpendiculaire à l'axe longitudinal de l'élément 3. Les doigts 203 sont par ailleurs répartis angulairement de façon symétrique par rapport à l'axe longitudinal de l'élément 3 (90 degrés entre deux doigts 203 adjacents).  The coupling device comprises a first intermediate element 3 having the general shape of a cylindrical ring and intended to be arranged concentrically around the first shaft 1 (FIG. 2). The inner surface of the first intermediate member 3 has a diameter and grooves 103 adapted to mesh with the outer surface of the first shaft 1. The first intermediate member 3 has a smooth cylindrical outer surface on which four radially oriented fingers 204 project. outside the body of the element 3. The four fingers 203 are located in the same plane perpendicular to the longitudinal axis of the element 3. The fingers 203 are also angularly distributed symmetrically with respect to the axis longitudinal of the element 3 (90 degrees between two adjacent fingers 203).

Le dispositif accouplement comprend un second élément 4 intermédiaire ayant la forme générale d'une bague cylindrique et destiné à être disposé concentriquement autour du premier élément 3 intermédiaire.  The coupling device comprises a second intermediate element 4 having the general shape of a cylindrical ring and intended to be arranged concentrically around the first intermediate element 3.

La surface intérieure du second élément 4 intermédiaire a un diamètre correspondant au diamètre extérieur du premier élément 3, et quatre rainures 204 longitudinales disposées relativement de façon à accueillir les doigts 203 du premier élément 3.  The inner surface of the second intermediate element 4 has a diameter corresponding to the outer diameter of the first element 3, and four longitudinal grooves 204 arranged relatively so as to receive the fingers 203 of the first element 3.

La surface extérieure du second élément 4 intermédiaire a un diamètre et des cannelures 304 longitudinales adaptés pour s'engrener avec la surface intérieure cannelée 301 du second arbre 2.  The outer surface of the second intermediate member 4 has a diameter and longitudinal grooves 304 adapted to mesh with the grooved inner surface 301 of the second shaft 2.

La figure 4 représente le dispositif d'accouplement monté entre les deux arbres concentriques (premier 3 et second 4 éléments intermédiaires enfilés entre les arbres 1, 2). Dès lors, lorsque l'un des deux arbres 1, 2 dit arbre menant a un couple de rotation, les moyens d'accouplement 3, 4 transmettent le couple à l'autre arbre 2, 1 dit mené. Le dispositif d'accouplement selon l'invention est homocinétique. En effet, le rapport de la vitesse de rotation entre l'arbre menant et l'arbre mené est égal à un.  Figure 4 shows the coupling device mounted between the two concentric shafts (first 3 and second 4 intermediate elements threaded between the shafts 1, 2). Therefore, when one of the two shafts 1, 2 said shaft leading to a torque, the coupling means 3, 4 transmit the torque to the other shaft 2, 1 said led. The coupling device according to the invention is homokinetic. Indeed, the ratio of the speed of rotation between the driving shaft and the driven shaft is equal to one.

io La transmission du couple entre le premier élément 3 intermédiaire et le second élément 4 intermédiaire est assurée par les doigts 203 du premier élément 3 qui coopèrent avec les rainures 204 du second élément 4. Ces mêmes moyens de liaison en rotation forme également une liaison rotule entre les deux éléments 3, 4 (et donc une liaison rotule entre les deux arbres 1, 2).  The transmission of the torque between the first intermediate element 3 and the second intermediate element 4 is provided by the fingers 203 of the first element 3 which cooperate with the grooves 204 of the second element 4. These same rotational connection means also form a ball joint between the two elements 3, 4 (and thus a ball joint connection between the two shafts 1, 2).

En effet, les deux paires de doigts 203 alignés forment respectivement deux pivots distincts et perpendiculaires. Les rainures longitudinales autorisent un jeu et donc un déplacement des doigts permettant l'inclinaison d'un arbre 1 par rapport à l'autre 2. Les figures 5 et 6 illustrent les deux arbres accouplés avec un décalage angulaire A de leurs axes de rotation respectifs.  Indeed, the two pairs of aligned fingers 203 respectively form two distinct and perpendicular pivots. The longitudinal grooves allow play and thus a movement of the fingers allowing the inclination of a shaft 1 relative to the other 2. Figures 5 and 6 illustrate the two shafts coupled with an angular offset A of their respective axes of rotation .

De plus, les moyens de liaison en rotation 203, 204 entre 25 les deux éléments 3, 4 peuvent permettre un coulissement longitudinal relatif d'un arbre par rapport à l'autre.  In addition, the rotational linking means 203, 204 between the two elements 3, 4 may allow relative longitudinal sliding of one shaft relative to the other.

Ainsi, tout en étant de structure simple et peu coûteuse, l'invention permet d'accoupler deux arbres en respectant leurs axes de rotation respectifs. L'invention est particulièrement adaptée à la transmission de couple entre deux arbres cannelés non co-axiaux.  Thus, while being simple and inexpensive structure, the invention allows to couple two shafts respecting their respective axes of rotation. The invention is particularly suitable for transmitting torque between two non-coaxial grooved shafts.

L'invention peut s'appliquer, par exemple, à l'accouplement d'une machine électrique (Moteur Hybride) avec l'arbre primaire d'une boîte de vitesses.  The invention can be applied, for example, to the coupling of an electric machine (Hybrid Engine) with the primary shaft of a gearbox.
