Definitions
- the present invention relates to a winding watch automatic, including an automatic winding weight, having a central part surrounded by paths of rolling a ball bearing, one of which is integral of said central part and the other is integral positioning means and removable attachment to the frame of the watch, a train of reducing gears to connect this mass of automatic winding to a barrel shaft and a reversing mechanism, to transform the movement of bidirectional rotation of said automatic winding weight in a unidirectional rotational movement, transmitted to said barrel tree.
- a watch of this type has already been proposed in the CH 1237-1269.
- This watch has a double clutch mechanism unidirectional formed by two stressed discs each by an eccentric force exerted by a driving finger so that each disc is locked against the surface interior of a drum secured to the oscillating weight in one direction of rotation and slides in the other direction of rotation, the two discs working in opposite direction one the other.
- These driving fingers are integral with two independent coaxial gears meshing with the cog of reassembly of the barrel.
- Such a mechanism is relatively complex and delicate, especially for a small caliber such than a ladies' caliber.
- a typical example of this accumulation of mobiles at center of movement is illustrated for example in CH-363 298, in which, in addition to the indicator cog of the watch necessarily placed in the center of the movement, we must add a bridge for fixing the mass pivot shaft of automatic winding, the board of this mass of automatic winding pivotally mounted on this shaft, and two inverters between this bridge and this ground board of automatic winding, unidirectional drive system of each of these inverters, as well as the spaces necessary between these different superimposed elements to allow them to rotate around this same pivot axis.
- the reversing mechanism is mounted coaxially on the axis of barrel.
- the volume which can thus be subtracted from the barrel to accommodate the mainspring reduces energy likely to be stored in it.
- the object of the present invention is to remedy, less in part, to the various drawbacks mentioned above, in in particular reducing the size of the winding mechanism automatic and allowing more rational use of space, especially at the center of the movement.
- this invention relates to a watch with automatic winding as defined in the claim 1.
- One of the main advantages of this invention is to use a large diameter ball bearing, allowing to provide a substantial volume in the center of the movement to accommodate the reversing mechanism.
- the space gained at the center of the movement does not require increasing the movement height, since the raceways of the ball bearing, used for pivoting the mass of automatic winding on the watch frame, surround the reversing mechanism and can therefore occur naturally on the same level as him. This provision therefore allows space saving in height, since it avoids overlapping above.
- the central part of the frame of the watch is no longer occupied by the pivoting members of the automatic winding weight which are distant outward, although its pivot axis coincides with the center of the movement and that the diameter of this mass therefore remains maximum.
- the gears of the reversing mechanism and therefore those who drive the gear train can therefore have a small diameter, since the central part of the movement is thus released and that these gables are inside and no longer outside of the ball bearing. Having drive sprockets small diameter gear train allows to reduce the number of mobiles in the reduction gear train, since these gables already constitute a first stage of reduction.
- the fact that inverters are integral with the oscillating mass also allows limit the blind spot, when reversing the direction of rotation of the automatic winding weight, to that of reverse gears.
- the gear train can also occupy a relatively clustered position around the center of the movement and thus leave the periphery free for mass automatic winding.
- the couple that can be transmitted by this is indeed a function of its inertia and, by consequently, of the mass which is located far from its axis of pivoting.
- the present invention therefore saves space also in plan, thanks to the grouping of the cog in the center and the reduced number of mobiles in the gear train.
- This winding mechanism includes a winding mass automatic formed of two parts, one central 2 to which an external part 1 in the general shape of a semicircle is fixed.
- the external part 1 presents a central opening 1a, engaged on an annular bearing 2a of the central part 2 ( Figure 2).
- An annular face oblique delimits, with the bearing 2a, a projection 2b.
- This oblique face of the projection 2b serves as a bearing surface for allow to create, using an appropriate tool, a centripetal deformation on the surface 2a on which the opening 1a is adjusted, thus making it possible to fix one to the other the two parts 1 and 2 forming the winding weight automatic.
- a ball bearing 3 is provided around the central part 2.
- a path of internal bearing 3a is provided, on the one hand at the periphery of this central part 2, on the other hand at the periphery of a ring 4 driven out on a cylindrical portion 2c of the central part 2 and used to retain a bearing ring 3c.
- An external raceway 3b is provided in an opening of an annular positioning member 5 and fixing to a bridge 6 of the watch frame, provided with a cylindrical opening 6a ( Figure 2) to receive a surface cylindrical complementary 5th of the annular member 5.
- the organ ring 5 still has at least two fixing lugs diametrically opposed 5a, 5b ( Figure 3), which extend to the outside of its cylindrical surface 5e.
- These legs fixing 5a, 5b are crossed by openings 5c, 5d surrounded by respective screw grooves, to allow fix these tabs 5a, 5b to the bridge 6 of the watch frame ( Figure 1) by means of screws 22, one of which is visible on the figure 2.
- a tubular portion 2d is formed concentrically with the axis of rotation of the central part 2 of the mass of automatic winding and extends downwards.
- a first inverter 7 is arranged in a 2nd groove (FIG. 3) formed concentrically with the pivot axis of this mass of automatic winding, on the upper side of the part central 2.
- This first inverter 7 (FIG. 2) has a tubular pivoting part 7a, engaged in the passage cylindrical of the tubular portion 2d which serves as bearing.
- a second inverter 8, integral with a pinion 9 is engaged from below on the external cylindrical surface of the tubular portion 2d which serves as its bearing.
- a pinion 10, integral with a threaded rod 10a, is screwed from underneath inside the tubular part of the first reverser 7, having a thread 7b complementary to the rod thread 10a. This assembly allows to join this pinion 10 with this reverser 7 and to retain axially the reverser 8 and the pinion 9 on the tubular element 2d, while leaving them free to rotate.
- Each reverser 7, 8 is engaged with a pinion satellite 11, respectively 12, pivotally mounted on a post 13, respectively 14. These tenons 13, 14 are driven out from the top, respectively from below the part central 2 of the winding weight.
- the teeth of each satellite pinion 11, 12 has a shape which does not allow, each satellite reverser-pinion system 7, 11; 8, 12 of ne rotate that in one direction, the rotation of the respective satellites 11, 12 in the opposite direction, causing the blocking of respective inverters 7, 8, which thus become integral in rotation of the winding weight 1, 2.
- the two inverters 7, 8 and their respective satellites 11, 12 are mounted coaxially with the pivot axis of the self-winding weight, but their pivot axes respective are sort of turned 180 ° one compared to each other.
- their respective relative rotations are reversed with respect to the common axis of rotation, when observes them from the same side of the automatic winding weight.
- the self-winding weight 1, 2 therefore carries its center two pinions 9, 10 whose diameters can be small since the pivoting of the mass is around the central part 2 carrying the reversing mechanism. This allows to have a reduction directly to from winding weight 1, 2 and back and forth rotation thereof.
- the reversing mechanism forms a single module, mounted on the central part 2 of the automatic winding weight. So to remove it, unscrew the two screws which fix the tabs 5a, 5b of the annular fixing member 5 to frame 6 of the watch. This allows very easy access to this mechanism for cleaning, lubricating and for carry out control operations.
- the two satellites 11, 12 being identical, there is no no risk of error between the one above and below. Their pivoting on tenons 13, 14 does not generate cantilevered. The fixing by these chased tenons removes the risk of losing these small satellite gears 11, 12.
- cutting the teeth of the entire mechanism can be obtained by generation. This allows to realize finer teeth than by cutting. Cutting per generation is more precise than cutting, as well from the point of view of the regularity of the profile of the teeth that of wheel diameter. It also gives a better state of tooth surface. Manufacturing tolerances can therefore be reduced, thereby increasing the range in which the reversing system can work properly.
- Blind spots when changing direction of rotation of the automatic winding weight 1, 2 are directly those of the planet gears and can be adjusted in particular by the pitch chosen for the teeth, or by the number of satellites 11, 12 working with inverters 7 and 8.

Description
La présente invention se rapporte à une montre à remontage automatique, comprenant une masse de remontage automatique, présentant une partie centrale entourée par des chemins de roulement d'un roulement à billes, dont l'un est solidaire de ladite partie centrale et l'autre est solidaire de moyens de positionnement et de fixation amovible au bâti de la montre, un train d'engrenages réducteurs pour relier cette masse de remontage automatique à un arbre de barillet et un mécanisme inverseur, pour transformer le mouvement de rotation bidirectionnelle de ladite masse de remontage automatique en un mouvement de rotation unidirectionnelle, transmis audit arbre de barillet.The present invention relates to a winding watch automatic, including an automatic winding weight, having a central part surrounded by paths of rolling a ball bearing, one of which is integral of said central part and the other is integral positioning means and removable attachment to the frame of the watch, a train of reducing gears to connect this mass of automatic winding to a barrel shaft and a reversing mechanism, to transform the movement of bidirectional rotation of said automatic winding weight in a unidirectional rotational movement, transmitted to said barrel tree.
Une montre de ce type a déjà été proposée dans le CH 1237/69. Cette montre comporte un double mécanisme d'embrayage unidirectionnel formés par deux disques sollicités chacun par une force excentrique exercée par un doigt entraíneur de sorte que chaque disque est bloqué contre la surface intérieure d'un tambour solidaire de la masse oscillante dans un sens de rotation et glisse dans l'autre sens de rotation, les deux disques travaillant en sens inverse l'un de l'autre. Ces doigts entraíneurs sont solidaires de deux pignons coaxiaux indépendants engrenant avec le rouage de remontage du barillet. Un tel mécanisme est relativement complexe et délicat, notamment pour un petit calibre tel qu'un calibre dame.A watch of this type has already been proposed in the CH 1237-1269. This watch has a double clutch mechanism unidirectional formed by two stressed discs each by an eccentric force exerted by a driving finger so that each disc is locked against the surface interior of a drum secured to the oscillating weight in one direction of rotation and slides in the other direction of rotation, the two discs working in opposite direction one the other. These driving fingers are integral with two independent coaxial gears meshing with the cog of reassembly of the barrel. Such a mechanism is relatively complex and delicate, especially for a small caliber such than a ladies' caliber.
La plupart des mécanismes de remontage automatique sont pourvus d'un mécanisme inverseur pour permettre de faire tourner l'arbre de barillet, solidaire de l'extrémité interne du ressort de barillet, dans le sens de l'armage de ce ressort, quel que soit le sens de rotation de la masse de remontage automatique. Sans un tel mécanisme inverseur, la moitié des mouvements angulaires de la masse de remontage automatique est en effet perdue, nécessitant donc le double de mouvement de la masse de remontage automatique pour le même degré d'armage du ressort de barillet.Most automatic winding mechanisms are provided with a reversing mechanism to allow turn the barrel shaft, integral with the internal end of the barrel spring, in the winding direction of this spring, whatever the direction of rotation of the mass of automatic winding. Without such a reversing mechanism, the half of the angular movements of the winding weight automatic is indeed lost, thus requiring double of movement of the automatic winding weight for the same degree of winding of the barrel spring.
Le problème posé par les mécanismes inverseurs est celui de l'encombrement, aussi bien en surface qu'en hauteur, quel que soit le système choisi. Il est bien évident que ce problème est d'autant plus difficile à résoudre que le diamètre du mouvement est petit. Lorsque le mécanisme inverseur se situe au début de la chaíne cinématique reliant la masse de remontage automatique à l'arbre de barillet, on se retrouve de plus avec le problème d'une accumulation d'organes montés pivotants autour de l'axe central du mouvement et donc d'une augmentation d'épaisseur de celui-ci. Ce problème est également d'autant plus gênant que le diamètre du mouvement est petit. The problem with reversing mechanisms is the size, both on the surface and in height, whatever system you choose. It is quite obvious that this problem is all the more difficult to solve since the diameter of the movement is small. When the mechanism reverser is located at the start of the kinematic chain connecting the mass of automatic winding to the barrel shaft, we moreover finds itself with the problem of an accumulation of organs mounted pivoting around the central axis of the movement and therefore an increase in thickness thereof. This problem is also all the more troublesome since the diameter of the movement is small.
Un exemple typique de cette accumulation de mobiles au centre du mouvement est illustré par exemple dans CH-363 298, dans lequel, en plus du rouage indicateur de la montre disposé forcément au centre du mouvement, on doit ajouter un pont pour la fixation de l'arbre de pivotement de la masse de remontage automatique, la planche de cette masse de remontage automatique montée pivotante sur cet arbre, et deux inverseurs entre ce pont et cette planche de masse de remontage automatique, le système d'entraínement unidirectionnel de chacun de ces inverseurs, ainsi que les espaces nécessaires entre ces différents éléments superposés pour leur permettre de tourner autour de ce même axe de pivotement.A typical example of this accumulation of mobiles at center of movement is illustrated for example in CH-363 298, in which, in addition to the indicator cog of the watch necessarily placed in the center of the movement, we must add a bridge for fixing the mass pivot shaft of automatic winding, the board of this mass of automatic winding pivotally mounted on this shaft, and two inverters between this bridge and this ground board of automatic winding, unidirectional drive system of each of these inverters, as well as the spaces necessary between these different superimposed elements to allow them to rotate around this same pivot axis.
Parmi les nombreuses solutions proposées pour résoudre les problèmes d'encombrement, on a déjà utilisé, dans le CH-329 448, la masse de remontage automatique pour y loger le mécanisme inverseur. L'inconvénient d'une telle solution est de réduire l'inertie de cette masse, puisqu'il faut l'évider pour y loger ce mécanisme qui comporte une grande proportion de vide. Par conséquent, on réduit le couple qui peut être transmis au ressort de barillet pour l'armer.Among the many solutions proposed to solve space problems, we have already used, in the CH-329 448, the automatic winding weight to accommodate the reversing mechanism. The downside of such a solution is to reduce the inertia of this mass, since it must be hollowed out to house this mechanism which has a large proportion empty. Therefore, we reduce the torque which can be transmitted to the barrel spring to arm it.
Selon d'autres solutions CH-308 939 et CH-308 940, le mécanisme inverseur est monté coaxialement sur l'axe de barillet. Or, le volume qui peut ainsi être soustrait au barillet pour y loger le ressort moteur, réduit l'énergie susceptible d'être emmagasinée dans celui-ci.According to other solutions CH-308 939 and CH-308 940, the reversing mechanism is mounted coaxially on the axis of barrel. However, the volume which can thus be subtracted from the barrel to accommodate the mainspring, reduces energy likely to be stored in it.
Le but de la présente invention est de remédier, au moins en partie, aux divers inconvénients susmentionnés, en réduisant notamment l'encombrement du mécanisme de remontage automatique et en permettant une utilisation plus rationnelle de l'espace, en particulier au centre du mouvement.The object of the present invention is to remedy, less in part, to the various drawbacks mentioned above, in in particular reducing the size of the winding mechanism automatic and allowing more rational use of space, especially at the center of the movement.
A cet effet, cette invention a pour objet une montre à
remontage automatique telle que définie dans la revendication
1. For this purpose, this invention relates to a watch with
automatic winding as defined in the
L'un des avantages principaux de cette invention consiste à utiliser un roulement à billes de grand diamètre, permettant de ménager un volume substantiel au centre du mouvement pour loger le mécanisme inverseur. L'espace gagné au centre du mouvement ne nécessite pas d'augmenter la hauteur du mouvement, puisque les chemins de roulement du roulement à billes, servant au pivotement de la masse de remontage automatique sur le bâti de la montre, entourent le mécanisme inverseur et peuvent donc se situer naturellement au même niveau que lui. Cette disposition permet donc un gain de place en hauteur, puisqu'elle évite la superposition susmentionnée.One of the main advantages of this invention is to use a large diameter ball bearing, allowing to provide a substantial volume in the center of the movement to accommodate the reversing mechanism. The space gained at the center of the movement does not require increasing the movement height, since the raceways of the ball bearing, used for pivoting the mass of automatic winding on the watch frame, surround the reversing mechanism and can therefore occur naturally on the same level as him. This provision therefore allows space saving in height, since it avoids overlapping above.
Grâce à cette disposition, la partie centrale du bâti de la montre n'est plus occupée par les organes de pivotement de la masse de remontage automatique qui sont éloignés vers l'extérieur, bien que son axe de pivotement coïncide avec le centre du mouvement et que le diamètre de cette masse reste donc maximum. Les pignons du mécanisme inverseur et donc ceux qui entraínent le rouage démultiplicateur, peuvent de ce fait avoir un petit diamètre, étant donné que la partie centrale du mouvement est ainsi libérée et que ces pignons se trouvent à l'intérieur et non plus à l'extérieur du roulement à billes. Le fait d'avoir des pignons d'entraínement du rouage démultiplicateur de petit diamètre permet de réduire le nombre de mobiles du train d'engrenages démultiplicateurs, étant donné que ces pignons constituent déjà un premier étage de démultiplication. Le fait que les inverseurs sont solidaires de la masse oscillante permet également de limiter l'angle mort, lors de l'inversion du sens de rotation de la masse de remontage automatique, à celui des pignons inverseurs.Thanks to this arrangement, the central part of the frame of the watch is no longer occupied by the pivoting members of the automatic winding weight which are distant outward, although its pivot axis coincides with the center of the movement and that the diameter of this mass therefore remains maximum. The gears of the reversing mechanism and therefore those who drive the gear train, can therefore have a small diameter, since the central part of the movement is thus released and that these gables are inside and no longer outside of the ball bearing. Having drive sprockets small diameter gear train allows to reduce the number of mobiles in the reduction gear train, since these gables already constitute a first stage of reduction. The fact that inverters are integral with the oscillating mass also allows limit the blind spot, when reversing the direction of rotation of the automatic winding weight, to that of reverse gears.
Grâce à la position centrale de l'inverseur double et au petit diamètre des pignons d'entraínement qui leurs sont solidaires, le rouage démultiplicateur peut aussi occuper une position relativement groupée autour du centre du mouvement et laisser ainsi la périphérie libre pour la masse de remontage automatique. Le couple qui peut être transmis par celle-ci est en effet fonction de son inertie et, par conséquent, de la masse qui se situe éloignée de son axe de pivotement.Thanks to the central position of the double reverser and the small diameter of the drive sprockets which are united, the gear train can also occupy a relatively clustered position around the center of the movement and thus leave the periphery free for mass automatic winding. The couple that can be transmitted by this is indeed a function of its inertia and, by consequently, of the mass which is located far from its axis of pivoting.
La présente invention permet donc de gagner de la place aussi en plan, grâce au regroupement du rouage au centre et au nombre réduit de mobiles du rouage démultiplicateur.The present invention therefore saves space also in plan, thanks to the grouping of the cog in the center and the reduced number of mobiles in the gear train.
D'autres avantages apparaítront au cours de la description
qui suit, relative à une forme d'exécution d'une montre
à remontage automatique objet de la présente invention,
donnée à titre d'exemple et illustrée à l'aide du dessin
schématique annexé dans lequel,
Seules les parties relatives au mécanisme de remontage automatique de la montre sont illustrées, le reste du mécanisme de la montre n'étant pas nécessaire à la compréhension de la présente invention.Only the parts relating to the winding mechanism automatic watch are illustrated, the rest of the mechanism of the watch is not necessary for understanding of the present invention.
Ce mécanisme de remontage comporte une masse de remontage
automatique formée de deux parties, l'une centrale 2 à
laquelle une partie externe 1 en forme générale de demi-cercle
est fixée. A cet effet, la partie externe 1 présente
une ouverture centrale 1a, engagée sur une portée annulaire
2a de la partie centrale 2 (figure 2). Une face annulaire
oblique délimite, avec la portée 2a, une saillie 2b. Cette
face oblique de la saillie 2b sert de surface d'appui pour
permettre de créer, à l'aide d'un outil approprié, une
déformation centripète sur la portée 2a sur laquelle l'ouverture
1a est ajustée, permettant ainsi de fixer l'une à
l'autre les deux parties 1 et 2 formant la masse de remontage
automatique.This winding mechanism includes a winding mass
automatic formed of two parts, one central 2 to
which an
Comme illustré par la figure 2, un roulement à billes 3
est ménagé autour de la partie centrale 2. Un chemin de
roulement interne 3a est ménagé, d'une part à la périphérie
de cette partie centrale 2, d'autre part à la périphérie
d'une bague 4 chassée sur une portion cylindrique 2c de la
partie centrale 2 et servant à retenir une bague de roulement
3c. Un chemin de roulement externe 3b est ménagé dans
une ouverture d'un organe annulaire 5 de positionnement et
de fixation à un pont 6 du bâti de la montre, muni d'une
ouverture cylindrique 6a (figure 2) pour recevoir une surface
cylindrique complémentaire 5e de l'organe de annulaire 5.As illustrated in Figure 2, a ball bearing 3
is provided around the
Ces surfaces cylindriques complémentaires 5e, 6a,
servent à positionner la masse de remontage automatique 1, 2
concentriquement au centre du bâti de la montre. L'organe
annulaire 5 comporte encore au moins deux pattes de fixation
diamétralement opposées 5a, 5b (figure 3), qui s'étendent à
l'extérieur de sa surface cylindrique 5e. Ces pattes de
fixation 5a, 5b sont traversées par des ouvertures 5c, 5d
entourées de noyures de vis respectives, pour permettre de
fixer ces pattes 5a, 5b au pont 6 du bâti de la montre
(figure 1) au moyen de vis 22 dont une est visible sur la
figure 2.These complementary
Une portion tubulaire 2d est ménagée concentriquement à
l'axe de rotation de la partie centrale 2 de la masse de
remontage automatique et s'étend vers le bas. Un premier inverseur
7 est disposé dans une noyure 2e (figure 3) formée
concentriquement à l'axe de pivotement de cette masse de
remontage automatique, sur la face supérieure de la partie
centrale 2. Ce premier inverseur 7 (figure 2) présente une
partie tubulaire de pivotement 7a, engagée dans le passage
cylindrique de la portion tubulaire 2d qui lui sert de
palier.A
Un second inverseur 8, solidaire d'un pignon 9, est
engagé depuis dessous sur la surface cylindrique externe de
la portion tubulaire 2d qui lui sert de palier. Un pignon
10, solidaire d'une tige filetée 10a, est vissé depuis
dessous à l'intérieur de la partie tubulaire du premier
inverseur 7, présentant un taraudage 7b complémentaire au
filetage de la tige 10a. Cet assemblage permet de solidariser
ce pignon 10 avec cet inverseur 7 et de retenir axialement
l'inverseur 8 et le pignon 9 sur l'élément tubulaire
2d, tout en les laissant libre de tourner.A second inverter 8, integral with a pinion 9, is
engaged from below on the external cylindrical surface of
the
Chaque inverseur 7, 8 est en prise avec un pignon
satellite 11, respectivement 12, monté pivotant sur un tenon
13, respectivement 14. Ces tenons 13, 14 sont chassés depuis
le dessus, respectivement depuis le dessous de la partie
centrale 2 de la masse de remontage. Comme on peut le
remarquer sur les figures 3 et 4, la denture de chaque
pignon satellite 11, 12 présente une forme qui ne permet, à
chaque système inverseur-pignon satellite 7, 11; 8, 12 de ne
tourner que dans un sens, la rotation des satellites respectifs
11, 12 en sens inverse, provoquant le blocage des
inverseurs respectifs 7, 8, qui deviennent ainsi solidaires
en rotation de la masse de remontage 1, 2.Each
Les deux inverseurs 7, 8 et leurs satellites respectifs
11, 12 sont montés coaxialement à l'axe de pivotement de la
masse de remontage automatique, mais leurs axes de pivotement
respectifs sont en quelque sorte tournés de 180° l'un
par rapport à l'autre. En d'autres termes, l'un des systèmes
inverseurs, comprenant l'inverseur 7 et son satellite 11,
monté sur la face supérieure de la partie centrale 2, présente
une symétrie miroir par rapport à l'autre système
inverseur comprenant l'inverseur 8 et son satellite 12,
monté sur la face inférieure de la partie centrale 2. Par
conséquent, leurs rotations relatives respectives sont
inversées par rapport à l'axe de rotation commun, lorsqu'on
les observe d'un même côté de la masse de remontage automatique.The two
Par conséquent, puisque les axes de pivotement des
satellites 11, 12 sont constamment solidaires de la masse de
remontage automatique 1, 2, lorsque ceux-ci bloquent les
inverseurs 7, respectivement 8, ils les rendent solidaires
en rotation de cette masse de remontage 1, 2 et leurs permettent
donc de transmettre la rotation de cette dernière.
En sens inverse, les inverseurs 7, 8 sont libres par rapport
à la masse de remontage 1, 2 et ne transmettent donc aucun
mouvement. Cependant, puisque les deux inverseurs travaillent
en sens inverse l'un de l'autre, il y en a donc toujours
un qui transmet la rotation de la masse de remontage
automatique.Therefore, since the pivot axes of the
Cette transmission de la rotation et donc du couple
moteur de la masse de remontage, est effectuée par les
pignons 9, 10 solidaires des inverseurs 8, respectivement 7.
De ce fait, ces pignons 9, 10 tournant, comme les inverseurs
8, 7, dans deux sens opposés, il est nécessaire que chacun
d'eux soit en prise avec deux mobiles différents du train
d'engrenages réducteurs, tournant eux-mêmes en sens opposés
l'un de l'autre.This transmission of rotation and therefore of torque
winding weight motor, is carried out by the
C'est ainsi que le pignon 9, solidaire de l'inverseur 8
est en prise avec un premier mobile 15 du train d'engrenages
réducteurs, tandis que le pignon 10, solidaire de l'inverseur
7 est en prise avec un deuxième mobile 16 de ce même
train d'engrenages réducteurs. Le premier mobile 15 est en
prise avec ce deuxième mobile 16 par l'intermédiaire d'un
pignon 15a. Un troisième mobile 17 engrène avec un pignon
16a du deuxième mobile et son pignon 17a engrène finalement
avec un rochet de barillet 18 solidaire de l'axe 19 du
barillet auquel est fixée l'extrémité interne du ressort de
barillet (non représenté). Comme dans toutes les montres, ce
rochet 18 coopère avec un cliquet 20 sollicité par un
ressort 21, qui ne lui permet de tourner que dans le sens de
l'armage du ressort de barillet.This is how the pinion 9, integral with the reverser 8
is engaged with a first mobile 15 of the gear train
reducers, while the
La masse de remontage automatique 1, 2 porte donc en
son centre deux pignons 9, 10 dont les diamètres peuvent
être petits puisque le pivotement de la masse se trouve
autour de la partie centrale 2 portant le mécanisme inverseur.
Ceci permet d'avoir une démultiplication directement à
partir de la masse de remontage 1, 2 et dans les deux sens
de rotation de celle-ci.The self-winding
Le mécanisme inverseur forme un seul module, monté sur
la partie centrale 2 de la masse de remontage automatique.
Il suffit donc pour l'enlever, de dévisser les deux vis qui
fixent les pattes 5a, 5b de l'organe de fixation annulaire 5
au bâti 6 de la montre. Ceci permet d'accéder très facilement
à ce mécanisme pour le nettoyer, le lubrifier et pour
effectuer les opérations de contrôle.The reversing mechanism forms a single module, mounted on
the
Comme on a déjà pu le remarquer, lorsque les pignons 9,
10 transmettent le couple de rotation de la masse de remontage
au train d'engrenages démultiplicateurs, ils sont solidaires
en rotation de la masse de remontage et ne tournent
donc pas sur leurs pivotements. Le rendement est donc excellent
puisqu'il n'est pas réduit par les forces de frottement
résultant du pivotement.As we have already noticed, when the
Les deux satellites 11, 12 étant identiques, il n'y a
pas de risque d'erreur entre celui du dessus et du dessous.
Leur pivotement sur des tenons 13, 14 n'engendre pas de
porte-à-faux. La fixation par ces tenons chassés supprime le
risque de perdre ces petits pignons satellites 11, 12.The two
Contrairement à certains mécanismes inverseurs dans lesquels les pignons inverseurs sont en prise avec des dentures intérieures qui ne peuvent être taillées que par découpage, le taillage des dentures de l'ensemble du mécanisme peut être obtenu par génération. Ceci permet de réaliser des dentures plus fines que par découpage. Le taillage par génération est plus précis que le découpage, aussi bien du point de vue de la régularité du profil des dents que du diamètre des roues. Il donne également un meilleur état de surface des dents. Les tolérances de fabrications peuvent donc être réduites, augmentant ainsi la plage dans laquelle le système inverseur peut fonctionner correctement.Unlike some reversing mechanisms in which the reverse gears are engaged with teeth interiors which can only be cut by cutting, cutting the teeth of the entire mechanism can be obtained by generation. This allows to realize finer teeth than by cutting. Cutting per generation is more precise than cutting, as well from the point of view of the regularity of the profile of the teeth that of wheel diameter. It also gives a better state of tooth surface. Manufacturing tolerances can therefore be reduced, thereby increasing the range in which the reversing system can work properly.
Les angles morts lors du changement de sens de rotation
de la masse de remontage automatique 1, 2 sont directement
ceux des pignons satellites et peuvent être ajustés notamment
par le pas choisi pour la denture, ou par le nombre de
satellites 11, 12 travaillant avec les inverseurs 7 et 8.Blind spots when changing direction of rotation
