Abstract

The pressure ring (13a) of the rotary coupling is solidly coupled in the axial direction to a second ring (14a) whose external surface (A) slopes in the opposite direction and bears against the mating internal surface of an additional external ring (17) forming the piston. The supply union (30) for the hydraulic fluid is connected directly to the cylinder (27). The angle of each taper surface is very slightly greater than the angle of frictional contact between the pairs of surfaces. The axial locking position of the external rings (16,17) can be restricted by a stop (24), e.g. a stop screw on one of them, and adjustable in the axial direction.

Description

Le brevet déposé le 11 Décembre 1980 sous le N 80 26614 concerne l'assemblage hydromécanique d'un moyeu sur un arbre pour lequel le moyeu est glissé sur arbre avec un jeu très faible, l'extérieur du moyeu étant usiné cylindrique avec une tolérence sérrée par rapport à l'alésage également cylindrique de deux anneaux relativement minces qui sont glissés avec un jeu très faible sur l'extérieur du moyeu.Ces deux anneaux ont leur partie extérieure en forme de conte, cône dont le sommet est concourant avec llaxe de l'anneau et dont la valeur de l'angle d'une génératrice par rapport à l'axe est légèrement supérieure à celle de l'angle correspondant au frottement de deux surfaces métal- liques correctement usinées et graissées glissant l'une sur l'autre. tes deux anneaux sont placés sur le moyeu en inversant le sens du canne d'un anneau par rapport à l'autre; les petits diamètres des canes sont appuyés l'un contre l'autre en étant rendus solidaires axialement l'un par rapport à l'autre; ces anneaux sont nunis de contre anneaux dont les alésages ont chacun un cône femelle épousant parfaitement le cône nâle de l'anneau sur lequel il est monté; à sa partie extérieure, l'un des contre anneau comporte, en direction de l'autre contre anneau, un épaulement avec centrage femelle, centrage dans lequel 1' autre contre anneau est engagé; un joint torique assure l'étanchéité vers 1' extérieur du verin hydraulique annulaire formé par les deux contre anneaux; le contre anneau faisant office de piston comporte sur sa périphérie, en prolongation de sa partie piston, un filetage male sur lequel un écrou est vissé.The patent filed on December 11, 1980 under N 80 26614 relates to the hydromechanical assembly of a hub on a shaft for which the hub is slid on the shaft with very little play, the outside of the hub being machined cylindrical with a tight tolerance compared to the also cylindrical bore of two relatively thin rings which are slid with a very weak play on the outside of the hub. These two rings have their outside part in the form of tale, cone whose top is concurring with the axis of l ring whose value of the angle of a generator with respect to the axis is slightly greater than that of the angle corresponding to the friction of two correctly machined and greased metal surfaces sliding one over the other . your two rings are placed on the hub by reversing the direction of the rod from one ring to the other; the small diameters of the canes are pressed against each other while being made axially integral with one another; these rings are provided with counter-rings, the bores of which each have a female cone which conforms perfectly to the male cone of the ring on which it is mounted; at its outer part, one of the counter ring comprises, in the direction of the other against ring, a shoulder with female centering, centering in which the other against ring is engaged; an O-ring seals towards the outside of the annular hydraulic cylinder formed by the two counter rings; the counter ring acting as a piston has on its periphery, in extension of its piston part, a male thread onto which a nut is screwed.

L'objet de la présente addition est de remplacer l'écrou précité par des élixefits mécaniques de blocage plus sinple,plus petits et moins cher, ceci tout particul fièrement lorsque pour l'accouplement d'arbres et de moyeux de très grand diamètre, un très grand écrou pose des problèmes de fabrication et de manutention inhabituels. A cet éffet l'écrou de blocage et sont filetage sont remplacés soit par une cale d'épaisseur réalisées en en deux ou plusieurs segments, soit par des vis nultiples sérrées chacune avec un couple faible, le bout de ces vis servant d'appui. Les Fig. I, II et III sont similaires à la Fig.I du brevet principal et représentent les modifications objet de la présente addition.Pour la Fig II l'écrou (repère 12 sur le brevet principal) est remplacé par une cale en deux parties 1 qui est placée entre les épaulements 2 et 3 des contre anneaux 4 et 5 lorsque ces derniers sont écartés l'un de l'autre par la pression hydraulique, cette cale 1 est coincée entre les épaulements 2 et 3 des contre anneaux 4 et 5 dès que la pression hydraulique est retirée. Pour retirer la cale 1 il suffit de remettre la pression hydraulique entre les contre anneaux 4 et 5, la cale 1 est alors décoincée et peut être retirée facilement.La Fig. II montre le remplacemen
de l'écrou du brevet principal par plusieurs vis 6 égalenent réparties autour de
l'axe 7 sur le rayon 8, ces vis ,de préférence à six pans creux, ont une partie lisse 9 avec un joint torique 10 qui assure l'étancheité hydraulique pour chaque vis dans la partie lisse 11 des trous qui sont taraudés en 12 dans le contre anneau 13. Lorsque les contre anneaux 13 et 14 sont écartés par la pression hydraulique, les vis 6 sont vissées pour prendre appui contre le contre anneau 14, ces vis 6 assurent le maintien de l'écartement des contre anneaux 13 et 14 lorsque la pression hydraulique est retirée. La Fig.III est une variante de la Fig.II dans laquelle les vis 6 sont situées sans joint torique individuel entre le verin annulaire situé entre les joints toriques 15 et 16 et l'anneau 17 du contre anneau 13; le fonctionnement est le mêne que dans le cal de la Fig.II de la présente addition, mais chaque vis 6 et son trou taraudé 12 dans le contre anneau 13 n'a pas besoin ni de partie lisse, ni de jednt torique; par contre ces vis sont plus proche de l'anneau 17 ce qui n'est pas sans influence sur le flux des éfforts de sérrage entre anneau 17 et contre anneau 13. The object of the present addition is to replace the aforementioned nut by more simple, smaller and less expensive mechanical locking elixefits, this especially proudly when for the coupling of shafts and hubs of very large diameter, a very large nut poses unusual manufacturing and handling problems. For this purpose the locking nut and its thread are replaced either by a shim made in two or more segments, or by tightened multiple screws each with a low torque, the end of these screws serving as support. Figs. I, II and III are similar to Fig. I of the main patent and represent the modifications which are the subject of this addition. For Fig II, the nut (reference 12 on the main patent) is replaced by a two-part shim 1 which is placed between the shoulders 2 and 3 of the counter-rings 4 and 5 when the latter are separated from one another by hydraulic pressure, this wedge 1 is wedged between the shoulders 2 and 3 of the counter-rings 4 and 5 as soon as hydraulic pressure is removed. To remove the wedge 1, simply put the hydraulic pressure between the counter rings 4 and 5, the wedge 1 is then loosened and can be removed easily. II shows the replacement
of the main patent nut by several screws 6 also distributed around
axis 7 on spoke 8, these screws, preferably with hexagon socket, have a smooth part 9 with an O-ring 10 which provides hydraulic sealing for each screw in the smooth part 11 of the holes which are tapped at 12 in the counter ring 13. When the counter rings 13 and 14 are separated by hydraulic pressure, the screws 6 are screwed to bear against the counter ring 14, these screws 6 maintain the spacing of the counter rings 13 and 14 when the hydraulic pressure is removed. Fig.III is a variant of Fig.II in which the screws 6 are located without individual O-ring between the annular cylinder located between the O-rings 15 and 16 and the ring 17 of the counter ring 13; the operation is the same as in the cal of Fig.II of the present addition, but each screw 6 and its tapped hole 12 in the counter ring 13 does not need either a smooth part or a toroidal jednt; on the other hand, these screws are closer to the ring 17, which is not without influence on the flow of the clamping forces between ring 17 and against ring 13.
