Abstract

In the mechanical selfwinding watch movement with an oscillating winding weight, the winding weight and the spring barrel driving the movement are pivoted coaxially, in the center of the movement, above the winding and the movement gears. The winding weight and the spring barrel have substantially the same thickness and they are on the same level. The spring barrel occupies almost the whole space in the path of the heavy sector of the winding weight. Due to the permissible size of such a spring barrel, the latter is able to store up an energy sufficient to keep the movement running during eight days at least.

Description

La présente invention a trait aux mouvements de montre mécaniques à remontage automatique par masse oscillante.The present invention relates to mechanical watch movements with automatic winding by oscillating weight.

Elle vise principalement à créer un tel mouvement qui ait une longue durée de marche en tous cas de plus de 72 h mais de préférence de l'ordre de huit jours, lorsqu'il est remonté complètement.Its main aim is to create such a movement which has a long running time in any case of more than 72 hours but preferably of the order of eight days, when it is completely wound up.

De nombreux mouvements de montre à durée de marche de cet ordre sont connus. Aucun n'est cependant équipé d'un mécanisme de remontage automatique. Un inconvénient important de ces mouvements connus à remontage manuel est que le porteur de la montre ne mémorise pas les jours nécessitant un remontage : ou bien il remonte le mouvement trop souvent, quand cela ne serait pas nécessaire, ou alors il oublie de le remonter et la montre s'arrête à des moments qui peuvent être fort inopportuns.Many watch movements with a running time of this order are known. None, however, are fitted with an automatic winding mechanism. An important drawback of these known movements with manual winding is that the wearer of the watch does not memorize the days requiring winding: either he wind the movement too often, when this would not be necessary, or he forgets to wind it and the watch stops at times which may be very inappropriate.

Selon l'invention, le barillet est logé dans la masse oscillante, coaxialement à celle-ci, au centre du mouvement. Les dimensions que cet agencement confère au barillet permettent d'y loger un ressort à grand nombre de spires, capable d'entraîner le mouvement pendant huit jours au moins, en développant un couple suffisant et constant pendant la presque totalité de son temps de désarmage. La montre équipée d'un tel mouvement peut par exemple, n'être portée que le dimanche et, ce jour-là, être remontée suffisamment pour rester en marche jusqu'au dimanche suivant.According to the invention, the barrel is housed in the oscillating mass, coaxial to it, in the center movement. The dimensions that this arrangement gives to the barrel make it possible to accommodate a spring with a large number of turns, capable of driving the movement for at least eight days, developing sufficient and constant torque during almost all of its disarming time. The watch fitted with such a movement can, for example, only be worn on Sunday and, on that day, be wound enough to stay on until the following Sunday.

Une forme d'exécution du mouvement selon l'invention est représentée schématiquement et à simple titre d'exemple au dessin annexé dans lequel:

  • la Fig. 1 en est une vue en plan avec deux petites parties arrachées ;
  • la Fig. 2 une coupe à plus grande échelle selon les lignes II-II-II de la Fig. 1, et
  • la Fig. 3 une coupe, comme la Fig. 2, selon la ligne III-III de la Fig. 1.
An embodiment of the movement according to the invention is shown schematically and simply by way of example in the appended drawing in which:
  • Fig. 1 is a plan view with two small parts torn off;
  • Fig. 2 a section on a larger scale along the lines II-II-II of FIG. 1, and
  • Fig. 3 a section, as in FIG. 2, along line III-III of FIG. 1.

Le remontage automatique du mouvement 1 est assuré par une masse oscillante 2. Cette masse est composée d'un secteur de couronne semi-circulaire pesant 3, qui est fixé à une couronne 4. Cette dernière présente une gorge périphérique 5 de profil rectangulaire dans sa face interne et une denture 6 dans un rebord externe inférieur 7. La masse 2 est montée de façon rotative coaxialement au mouvement 1 par cinq galets à roulement à billes 8. Le chemin de roulement externe des galets 8 est engagé dans la gorge 5 de la couronne 4, tandis que leur chemin de roulement interne est solidaire d'un tenon 9, dont les extrémités sont enchâssées dans des couronnes fixes, respectivement inférieure 10 et supérieure 11. Quant à la denture 6, elle est en prise avec un pignon 12 pivoté en porte-à-faux dans un roulement à billes 13, dont le chemin de roulement externe est engagé à force dans une forure de la platine 14 du mouvement 1.The automatic winding of the movement 1 is ensured by an oscillating mass 2. This mass is composed of a semicircular crown sector weighing 3, which is fixed to a crown 4. The latter has a peripheral groove 5 of rectangular profile in its internal face and a toothing 6 in a lower external rim 7. The mass 2 is rotatably mounted coaxially with the movement 1 by five ball bearing rollers 8. The external raceway of the rollers 8 is engaged in the groove 5 of the crown 4, while their path of internal bearing is integral with a lug 9, the ends of which are encased in fixed crowns, respectively lower 10 and upper 11. As for the toothing 6, it is engaged with a pinion 12 pivoted in overhang in a ball bearing 13, the external raceway of which is forcibly engaged in a hole in the plate 14 of movement 1.

Par ses rotations dans un sens et dans l'autre, la masse 2 arme un ressort 15 contenu dans le barillet 16. Ce dernier est logé à l'intérieur de la masse oscillante 2. Il occupe pratiquement tout l'espace libre à l'intérieur du chemin parcouru par le secteur 3 de cette masse. La Fig. 2 montre que le barillet 16 et la masse 2 ont approximativement la même épaisseur et que leurs faces supérieures et inférieures sont approximativement au même niveau.By its rotations in one direction and in the other, the mass 2 arms a spring 15 contained in the barrel 16. The latter is housed inside the oscillating mass 2. It occupies practically all the free space in the inside the path traveled by sector 3 of this mass. Fig. 2 shows that the barrel 16 and the mass 2 have approximately the same thickness and that their upper and lower faces are approximately at the same level.

Le tambour 17 du barillet 16 monté de façon rotative, coaxialement à la masse 2, sur cinq galets à roulement à billes 18. A cet effet, la face externe de la paroi latérale du tambour 17 présente une gorge périphérique 19, de profil rectangulaire, dans laquelle plongent les chemins de roulement externes des galets 18. A l'instar des galets 8, les chemins de roulement internes des galets 18 sont solidaires de tenons 20, dont les extrémités sont aussi enchassées dans les couronnes 10, 11. La Fig. montre que chaque tenon 20 est planté dans les couronnes 10, 11 à égale distance des tenons 9 d'une paire de galets 8 adjacents. Ces couronnes 10, 11 sont fixées sur la platine 14 de façon non représentée. La Fig. 2 montre qu'elles n'accroissent nullement l'épaisseur du mouvement 1.The drum 17 of the barrel 16 rotatably mounted, coaxially with the mass 2, on five rollers with ball bearings 18. For this purpose, the external face of the side wall of the drum 17 has a peripheral groove 19, of rectangular profile, into which the external raceways of the rollers 18 plunge. Like the rollers 8, the internal raceways of the rollers 18 are integral with tenons 20, the ends of which are also embedded in the crowns 10, 11. FIG. shows that each stud 20 is planted in the crowns 10, 11 equidistant from the studs 9 of a pair of adjacent rollers 8. These rings 10, 11 are fixed to the plate 14 in a manner not shown. Fig. 2 shows that they in no way increase the thickness of movement 1.

L'ouverture centrale du tambour 17 du barillet 16 est engagée à force sur l'extrémité d'un manchon 21, dont la forme centrale 22 permet de soutenir l'arbre de la roue de centre ou grande moyenne 23, lors de la pose des aiguilles . La bonde du barillet 16 est constituée par un simple manchon 24 sur lequel est formé le crochet d'ancrage 25 de l'extrémité interne du ressort 15. Les chemins de roulement externes de deux galets 26 à roulement à billes sont enchâssés dans le manchon 24, tandis que les chemins de roulement internes de ces galets 26 sont solidaires du manchon 21. A sa base, le manchon 24 présente 2 ergots 27, qui sont engagés dans des découpures correspondantes du rochet 28 et fixés à ce dernier de manière à solidariser celui-ci et le manchon 24.The central opening of the drum 17 of the barrel 16 is forcibly engaged on the end of a sleeve 21, the central shape of which 22 makes it possible to support the shaft of the center or large medium wheel 23, when installing the needles. The plug of the barrel 16 is constituted by a simple sleeve 24 on which is formed the anchoring hook 25 of the internal end of the spring 15. The external raceways of two rollers 26 with ball bearings are embedded in the sleeve 24 , while the internal raceways of these rollers 26 are integral with the sleeve 21. At its base, the sleeve 24 has 2 pins 27, which are engaged in corresponding cutouts of the ratchet 28 and fixed to the latter so as to secure that and the sleeve 24.

Le rouage de remontage (Fig. 1 et 3), qui relie au rochet 28 le pignon 12, en prise avec la denture 6 de la couronne 4 de la masse 2, comprend un inverseur 29 de type connu et trois mobiles de démultiplication 30, 31, 32. L'inverseur 29 est composé de deux paires de roues 33, 34; 35, 36.The winding train (Fig. 1 and 3), which connects the pinion 12 to the ratchet 28, in engagement with the toothing 6 of the crown 4 of the mass 2, comprises an inverter 29 of known type and three reduction gears 30, 31, 32. The reverser 29 is composed of two pairs of wheels 33, 34; 35, 36.

Chacune de ces paires est pivotée en porte-­à-faux dans un galet à roulement à billes 37, 38, dont le chemin de roulement externe est engagé à force dans une forure de la platine 14. Les roues supérieures 33 et 35 ont le même diamètre et sont en prise l'une avec l'autre. Tandis que les roues inférieures 34 et 36, également de même diamètre, mais plus petit que celui des roues supérieures 33, 35, sont montées folles sur leur arbre respectif, les roues supérieures 33 et 35 sont solidaires des chemins de roulement externes de deux galets à roulement à billes 39, 40, dont les chemins de roulement internes sont solidaires des arbres correspondants.Each of these pairs is pivoted in overhang in a roller with ball bearing 37, 38, the external raceway of which is forcibly engaged in a borehole of the plate 14. The upper wheels 33 and 35 have the same diameter and are engaged with each other. While the lower wheels 34 and 36, also of the same diameter, but smaller than that of the upper wheels 33, 35, are mounted idly on their respective shafts, the upper wheels 33 and 35 are integral with the external raceways of two rollers at ball bearing 39, 40, the internal raceways of which are integral with the corresponding shafts.

Seule la roue supérieure 33 est en prise avec le pignon 12, alors que les deux roues inférieures 34, 36 sont toutes deux en prise avec la roue du premier mobile de démultiplication 30. Des billes de blocage 41 sont insérées entre les deux roues de chacune des paires de l'inverseur 29. Ces billes 41 ont pour effet de solidariser les roues inférieures 34, 36 aux roues supérieures 33, 35 respectives, lorsque ces dernières tournent dans un sens, par exemple horaire dans la Fig. 1, et de laisser libres les roues inférieures 34, 36 quand les roues supérieures 33, 35 tournent dans l'autre sens, antihoraire.Only the upper wheel 33 is engaged with the pinion 12, while the two lower wheels 34, 36 are both engaged with the wheel of the first reduction gear 30. Locking balls 41 are inserted between the two wheels of each pairs of the reverser 29. These balls 41 have the effect of securing the lower wheels 34, 36 to the respective upper wheels 33, 35, when the latter rotate in a direction, for example clockwise in FIG. 1, and to leave the lower wheels 34, 36 free when the upper wheels 33, 35 rotate in the opposite direction, counterclockwise.

Ainsi, si le pignon 12 tourne dans ie sens antihoraire, ia roue 33 tournera dans le sens horaire et entraînera la roue 34 avec elle. Cette dernière entraînera alors la roue du mobile 30 dans le sens antihoraire. De son côté, la roue 35 sera entraînée par la roue 33 dans le sens antihoraire et cette dernière laissera tourner librement la roue 36, entraînée dans le sens horaire par la roue du mobile 30.Thus, if the pinion 12 rotates counterclockwise, the wheel 33 will rotate clockwise and drive the wheel 34 with it. The latter will then drive the wheel of the mobile 30 counterclockwise. For its part, the wheel 35 will be driven by the wheel 33 counterclockwise and the latter will allow the wheel 36 to rotate freely, driven in the clockwise direction by the wheel of the mobile 30.

Au contraire, si le pignon 12 tourne dans le sens horaire, il entraînera la roue 33 dans le sens antihoraire et celle-ci entraînera à son tour la roue 35 dans le sens horaire. La roue 36 sera alors solidarisée à la roue 35 et elle entraînera la roue du mobile 30 dans le sens antihoraire. La roue 33 laissera alors tourner librement la roue 34, qui sera entraînée dans le sens horaire par la roue du mobile 30.On the contrary, if the pinion 12 rotates clockwise, it will drive the wheel 33 counterclockwise and this in turn will drive the wheel 35 clockwise. The wheel 36 will then be secured to the wheel 35 and it will drive the wheel of the mobile 30 counterclockwise. The wheel 33 will then allow the wheel 34 to rotate freely, which will be driven clockwise by the wheel of the mobile 30.

Que le pignon 12 et par conséquent la masse 2 tournent dans un sens ou dans l'autre, le mobile 30 sera toujours entraîné dans le même sens antihoraire par l'inverseur 29. Les mobiles de démultiplication 31 et 32 transmettent ainsi toutes les rotations du mobile 30 au rochet 28 dans le sens d'armage du ressort 15.Whether the pinion 12 and consequently the mass 2 rotate in one direction or the other, the mobile 30 will always be driven in the same counterclockwise direction by the reverser 29. The reduction mobile 31 and 32 thus transmit all the rotations of the movable 30 to the ratchet 28 in the winding direction of the spring 15.

Comme les roues de l'inverseur 29, les mobiles de démultiplication 30, 31, 32 sont pivotés à l'aide de galets à roulement à billes 42, 43, 44 dont les chemins de roulement externes sont enchâssés dans des forures de la platine 14, les mobiles 30 et 32 étant montés en porte-à-faux.Like the wheels of the reverser 29, the reduction gears 30, 31, 32 are pivoted by means of rollers with ball bearings 42, 43, 44 whose external raceways are embedded in the holes of the plate 14 , the mobiles 30 and 32 being mounted in cantilever.

De son côté, le barillet 16 engrène avec le pignon 45 d'une première roue de huitaine 46, elle-­même en prise avec le pignon 47 d'une seconde roue de huitaine 48. Cette roue 48 est en prise avec le pignon 49 de la grande moyenne 23, qui entraîne un rouage de finissage conventionnel, comprenant notamment une petite moyenne 50, une roue de champ ou de seconde 51, une roue d'ancre 52 et un échappement comprenant une ancre (non représentée), pivotée en 53 et un balancier 54.For its part, the barrel 16 meshes with the pinion 45 of a first eighth wheel 46, itself engaged with the pinion 47 of a second eighth wheel 48. This wheel 48 is engaged with the pinion 49 of the large medium 23, which drives a conventional gear train, comprising in particular a small medium 50, a field or second wheel 51, an anchor wheel 52 and an escapement comprising an anchor (not shown), pivoted at 53 and a pendulum 54.

A part le premier mobile de huitaine 45, 46 qui, en raison de l'effort auquel il ist soumis par le barillet 16, a les extrémités de son arbre pivotées dans deux galets à roulement à billes 55, 56 dont les chemins de roulement externes sont enchâssés respectivement dans la platine 14 et la couronne supérieure 11, tous les autres mobiles 47, 48; 49, 23; 50; 51; 52 et 54 sont pivotés dans un seul galet à roulement à billes 57, 58, 59, 60, certains en porte-à-faux. Cet agencement connu des rouages du mouvement 1 a notoirement pour effet de réduire l'épaisseur du mouvement par rapport à ceux dont les mobiles sont supportés par deux paliers, dans lesquels sont engagés des pivots formés aux extrémités de leur arbre. Le mouvement 1 comprend, enfin, une roue des minutes ou chaussée 61, calée sur l'arbre 22 de la grande moyenne 23 et portant une aiguille des minutes 62, ainsi qu'une roue à canon des heures 63, pivotée autour de la chaussée 61 et portant une aiguille des heures 64. Le mouvement 1, dont le diamètre est celui d'un mouvement usuel de montre d'homme, peut être construit avec une épaisseur de l'ordre de 3 mm.Apart from the first eight week mobile 45, 46 which, due to the force to which it is subjected by the barrel 16, has the ends of its shaft pivoted in two rollers with ball bearings 55, 56 including the external raceways are respectively embedded in the plate 14 and the upper crown 11, all other mobiles 47, 48; 49, 23; 50; 51; 52 and 54 are pivoted in a single roller with ball bearings 57, 58, 59, 60, some in overhang. This known arrangement of the cogs of movement 1 has the notorious effect of reducing the thickness of the movement relative to those whose mobiles are supported by two bearings, in which are engaged pivots formed at the ends of their shaft. Movement 1 includes, finally, a minute wheel or pavement 61, wedged on the shaft 22 of the large average 23 and carrying a minute hand 62, as well as a cannon wheel of hours 63, pivoted around the pavement 61 and carrying an hour hand 64. Movement 1, the diameter of which is that of a usual movement for a men's watch, can be constructed with a thickness of the order of 3 mm.
