La figure 2 représente le dispositif de la figure 1 démonté.Figure 2 shows the device of Figure 1 disassembled.

La figure 3 représente un second mode d'exécution d'un dispositif selon l'invention.FIG. 3 represents a second embodiment of a device according to the invention.

La figure 4 représente la -variante de la figure 3 en position démontée.Figure 4 shows the variant of Figure 3 in the disassembled position.

La figure 1 représente en coupe axiale un dispositif selon l'invention comprenant un premier organe l qui se présente sous la forme générale d'un moyeu rendu solidaire de l'arbre de sortie 5 d'une machine rotative par exemple au moyen d'une goupille 7 de manière à entraRner en rotation un second organe 9 telle une poulie, par exemple, qui vient coiffer extérieurement ledit moyeu en prenant appui sur une collerette extérieure ll de ce dernier et par rapport auquel il est verrouillé à l'aide d'au moins deux et de préférence une pluralité de billes 13 ou à toutes autres pièces de verrouillage disposées chacune dans un logement 15 pratiqué dans l'organe 1 et coopérant avec une encoche 17 prévue sur l'organe 9 tout en étant en contact radial avec le corps 19 d'une piece formant bouchon insérée a l'intérieur du moyeu à ltextremité opposée à celle qui reçoit l'arbre et maintenue dans cette position par l'action d'un ressort 23 disposé entre ledit corps et le fond 25 du second organe qui présente une ouverture centrale traversée par une tige 27 prolongeant le corps 19 et qui se termine par une tête 29 normalement en appui extérieur sur l'organe 9 et destinée a permettre sa saisie par un terminal de préhension pouvant être constitué par un grappin 31 ou même par le bras d'un robot.Figure 1 shows in axial section a device according to the invention comprising a first member l which is in the general form of a hub made integral with the output shaft 5 of a rotary machine for example by means of a pin 7 so as to cause a second member 9 to rotate, such as a pulley, for example, which covers said hub externally by bearing on an external flange ll of the latter and with respect to which it is locked using at least two and preferably a plurality of balls 13 or to any other locking parts each disposed in a housing 15 formed in the member 1 and cooperating with a notch 17 provided on the member 9 while being in radial contact with the body 19 of a piece forming a plug inserted inside the hub at the end opposite to that which receives the shaft and maintained in this position by the action of a spring 23 disposed between said body and the bottom 25 of the second member which near ente a central opening crossed by a rod 27 extending the body 19 and which ends with a head 29 normally in external support on the member 9 and intended to allow its seizure by a gripping terminal which can be constituted by a grapple 31 or even by the arm of a robot.

L'effort de traction axiale F exercé par le grappin sur la tête 29 entratne, par compression du ressort, la tige et le corps 19 qui en est solidaire et dont la partie supérieure se présente sous la forme d'un anneau 33 qui vient prendre appui sur un épaulement interne 35 du second organe auquel il transmet lI effort de traction axiale et qu' il entraine également avec lui après que les billes aient été repoussées radialement vers 1' intérieur hors des encoches 17, les logements 15 étant de préférence conçus de manière à les maintenir prisonnières de l'organe 1 alors libéré (Figure 2).The axial tensile force F exerted by the grapple on the head 29 drives, by compression of the spring, the rod and the body 19 which is integral therewith and the upper part of which is in the form of a ring 33 which takes pressing on an internal shoulder 35 of the second member to which it transmits the axial tensile force and which it also carries with it after the balls have been pushed radially inwards out of the notches 17, the housings 15 preferably being designed to so as to keep them captive of the member 1 then released (Figure 2).

Dans un deuxième temps, le grappin peut également, en saisissant la base 11, retirer de l'enceinte inaccessible ou dangereuse où elle est disposé, la machine d' entrainement liée à l'arbre 5.In a second step, the grapple can also, by grasping the base 11, withdraw from the inaccessible or dangerous enclosure where it is placed, the drive machine linked to the shaft 5.

La figure 3 represente une variante qui permet le retrait des billes 13 avec le second organe 9' qui se présente également sous la forme d'une cloche comportant un épaulement radial 36 en appui sur la base 11 du premier organe 1 qui est sensiblement identique à celui décrit à la figure 1 et qui comporte des encoches 17' avec lesquelles coopèrent les billes 13 maintenues dans des logements 15' pratiqués dans la paroi latérale du second organe tout en étant en contact radial extérieur avec une pièce 19' qui vient coiffer ce dernier en prenant un appui extérieur sur les billes le long d'une paroi sensiblement cylindrique qui se prolonge vers le bas par une raite conique évasée D qui se termine par une aile sensiblement cylindrique 3ladite pièce 19' comprend également une tête 39 présentant une rainure d'appui 41 des achoiresdu grappin 31 et munie d'une tige 27' qui traverse le fond du second organe 9' pour se terminer par une collerette radiale 40 sur laquelle prend appui un ressort 23' dont l'autre extrémité vient contre épaulement 44 ceinturant le passage de la tige 27' à travers le fond de 9'.Le second organe comporte également, dispose intérieurement, un élément rapporté comprenant une base en forme d'un anneau 42 traversé sans contact par la tige 27' entourée de son ressort 23' et dans un trou excentré duquel peut coulisser un guide 45 vissé dans le fond dudit second organe, laquelle base se prolonge par une paroi cylindrique 47 qui se termine par une collerette radiale 49 qui vient au niveau de 1' ext?emité supérieure du moyeu 3 et qui menage-ainsi un espace annulaire cylindrique dans lequel est disposé un ressort sous tension 51 dont les extrémités sont en appui sur le second organe et la collerette 49 respectivement.Figure 3 shows a variant which allows the withdrawal of the balls 13 with the second member 9 'which is also in the form of a bell having a radial shoulder 36 bearing on the base 11 of the first member 1 which is substantially identical to that described in FIG. 1 and which includes notches 17 ′ with which the balls 13 maintained in housings 15 ′ formed in the side wall of the second member while being in external radial contact with a part 19 ′ which covers the latter by taking external support on the balls along a substantially cylindrical wall which extends downwards by a flared conical reat D which ends in a substantially cylindrical wing 3, said part 19 ′ also comprises a head 39 having a groove of support 41 of the grapple grippers 31 and provided with a rod 27 ′ which crosses the bottom of the second member 9 ′ to end in a radial flange 40 on which a spring 23 ′ is supported the other end of which comes against shoulder 44 encircling the passage of the rod 27 ′ through the bottom of 9 ′. The second member also includes, internally, an attached element comprising a base in the form of a ring 42 crossed without contact by the rod 27 'surrounded by its spring 23' and in an eccentric hole which can slide a guide 45 screwed into the bottom of said second member, which base is extended by a cylindrical wall 47 which ends in a radial flange 49 which comes to the level of the upper end of the hub 3 and which thus forms a cylindrical annular space in which a tensioned spring 51 is arranged, the ends of which bear on the second member and the flange 49 respectively.

L'effort de traction exercé par les machoîres du grappin 31 sur le fond de la rainure 41 fait coulisser selon la direction, généralement verticale, la pièce 19' jusqu'au moment où les billes basculent dans l'encoche circulaire 52 créée par la rampe 37 tout en restant maintenues intérieurement par son aile 38 et libèrent ainsi l'organe 1 ; le déplacement vertical de la pince 19' comprime le ressort 23' contre le fond du second organe également libéré qui se trouve ainsi entravé avec elle sur une hauteur h jusqu a ce que les billes prennent appui intérieurement contre la collerette 49 pendant que le guide 45 coulisse sur l'anneau 42 sous l'action du ressort - SI de la mne valeur h.The tensile force exerted by the jaws of the grapple 31 on the bottom of the groove 41 causes the part 19 ′ to slide in the direction, generally vertical, until the balls rock in the circular notch 52 created by the ramp 37 while remaining internally held by its wing 38 and thus release the member 1; the vertical movement of the clamp 19 'compresses the spring 23' against the bottom of the second also released member which is thus hampered with it over a height h until the balls bear internally against the flange 49 while the guide 45 slides on the ring 42 under the action of the spring - SI of the same value h.

Les pièces 19', 9', 42, 45, 51, 13 restent dans leurs positions relativesreprésentees la figure 4, grâce, notamment, A la tête épanouie 53 du guide 45 qui prend appui sur la face inférieure de l'anneau 42, pour être entraidées simultanément par le grappin. Comme indiqué précédemment, les organes peuvent donc être déverrouillés, séparés et retirés à l'aide d'un simple terminal exerçant des efforts de traction selon une direction verticale correspondant sensiblement à l'axe du dispositif. The parts 19 ′, 9 ′, 42, 45, 51, 13 remain in their relative positions represented in FIG. 4, thanks in particular to the open head 53 of the guide 45 which is supported on the underside of the ring 42, to be supported simultaneously by the grapple. As indicated above, the members can therefore be unlocked, separated and removed using a simple terminal exerting tensile forces in a vertical direction corresponding substantially to the axis of the device.

Bien entendu le dispositif selon l'invention est applicable à toutes sortes de machines et notamment à des machines à scier. Of course the device according to the invention is applicable to all kinds of machines and in particular to sawing machines.
