Abstract
Description
L'invention a pour objet un mobile destiné à venir en contact avec un autre élément mobile ou fixe.The subject of the invention is a mobile intended to come into contact with another mobile or fixed element.
En horlogerie, par exemple, lors de l'ajout sur un mécanisme existant d'un mobile additionnel, il arrive souvent que l'axe d'un mobile doive passer à travers toute la platine pour afficher, par exemple, une indication sur le cadran. De ce fait, l'axe du mobile peut rencontrer un ou plusieurs composants existants du mouvement. Il survient alors de nombreuses complications si l'on doit changer l'emplacement de l'axe de pivotement du mobile traversant toute la platine. Ce problème a amené la titulaire à proposer un mobile pouvant être contraint à se déplacer par rapport à son axe, de manière à éviter la rencontre avec un axe ou toute autre pièce du mouvement. La contrainte exercée sur le mobile consistera à déplacer l'axe dudit mobile, dont la partie centrale subira une déformation, la périphérie du mobile étant déplacée latéralement. Ainsi, la titulaire se propose de proposer un mobile présentant en son centre une certaine élasticité lui permettant de subir des déplacements sans changer un entre-axe, sans altérer sa fonction et sans changer son rendement.In watchmaking, for example, when adding on an existing mechanism of an additional mobile, it often happens that the axis of a mobile must pass across the board to display, for example, an indication on the dial. Thereby, the axis of the mobile can meet one or more existing components of the movement. It then occurs many complications if you have to change the location of the pivot axis of the mobile crossing the whole plate. This problem led to the holder to offer a mobile that can be forced to move relative to its axis, so as to avoid meeting with an axis or any other piece of the movement. The constraint exerted on the mobile will consist in moving the axis of said mobile, whose central part will undergo a deformation, the periphery of the mobile being moved laterally. Thus, the licensee proposes to offer a mobile presenting in its center a certain elasticity allowing to undergo displacements without changing a center distance, without altering its function and without changing its performance.
Le mobile selon l'invention est caractérisé en ce qu'il comprend un moyeu tournant sur son axe, et une zone de transmission ou de roulement destinée à venir en contact avec l'élément mobile ou fixe, une zone élastique susceptible de subir une déformation étant intercalée entre le moyeu et la zone de transmission.The mobile according to the invention is characterized in that it comprises a hub rotating on its axis, and a transmission or rolling area intended to come into contact with the mobile or fixed element, an elastic zone likely to undergo a deformation being interposed between the hub and the transmission area.
Selon un mode d'exécution préféré, la zone élastique peut être une mousse déformable, ou être constituée par une succession de lamelles reliant le moyeu à la zone de transmission ou de roulement.According to a preferred embodiment, the area elastic may be a deformable foam, or be constituted by a succession of lamellae connecting the hub at the transmission or bearing area.
La zone de transmission ou de roulement peut se présenter sous forme d'une roue dentée.The transmission or rolling area can take the form of a gear wheel.
Le mobile selon l'invention peut être soumis à une pression exercée par un pont ou un étagement appliqué sur la zone de transmission, la pression exercée par le pont amenant le mobile au contact d'un autre mobile à entraíner en déformant la zone élastique et en déplaçant l'axe de rotation dudit mobile.The mobile according to the invention can be submitted at a pressure exerted by a bridge or a stage applied to the transmission area, the pressure exerted by the bridge bringing the mobile into contact another mobile to train by deforming the area elastic and by moving the axis of rotation of said mobile.
Le mobile peut être utilisé comme partie constituante d'un embrayage.Mobile can be used as part component of a clutch.
La zone de transmission du mobile peut présenter une succession de dents butant contre un profilé d'un pont ou d'une noyure fixe, l'avance d'un pas ou d'une dent étant réalisée par la déformation de la zone élastique du mobile. Dans ce cas, le mobile peut se présenter sous forme d'une étoileThe transmission area of the mobile can present a succession of teeth abutting against a profile of a fixed bridge or recess, the advance of a step or a tooth being produced by the deformation of the elastic area of the mobile. In this case, the mobile can be in the form of a star
La zone de transmission du mobile peut être agencée pour réaliser un roulement ou un entraínement à friction. L'invention a également pour objet une utilisation du mobile dans la mécanique en général, en particulier dans l'automobile, l'aviation, la médecine, etc. The transmission area of the mobile can be arranged to produce a bearing or a friction drive. The invention also for object a use of the mobile in the mechanics in general, especially in automotive, aviation, medicine, etc.

Le mobile décrit dans les différents modes d'exécution a été développé pour l'industrie horlogère. Son application n'est cependant pas limitée à ce domaine particulier, et peut être étendue à la mécanique en général, en particulier à l'automobile, à l'aviation, à la micro-mécanique, à la machine-outil, à la médecine, et à tous les domaines de la technique dans lesquels un mobile doit être amené en contact avec un élément mécanique fixe ou un mobile, par une déformation de la structure correspondant à un déplacement de son centre de rotation.The mobile described in the different modes was developed for industry watchmaking. However, its application is not limited to this particular area, and may be extended to mechanics in general, in particular to automotive, aviation, micro-mechanics, the machine tool, medicine, and all technical fields in which a mobile must be brought into contact with a mechanical element fixed or mobile, by a deformation of the structure corresponding to a displacement of sound center of rotation.
Le mobile représenté dans les différents modes d'exécution a été développé pour l'industrie Le mobile représenté dans le mode d'exécution de la figure 1 permet, une fois mis en place, d'engrainer avec un autre mobile ou toute autre sorte de transmission en étant décentré de son axe de pivotement A.The mobile represented in the different execution modes was developed for industry The mobile represented in the embodiment of the Figure 1 allows, once in place, to generate with another mobile or any other kind of transmission by being off-center from its axis of pivoting A.
Le mobile 1 est formé de trois parties distinctes:
- un
moyeu 2, - une partie élastique 3, et
- une zone de
transmission 4
- a
hub 2, - an
elastic part 3, and - a
transmission zone 4
Dans la figure 1, le mobile 1 engraine un
autre mobile 5, et est entraíné par un pignon 6, qui
exerce une pression latérale sur la zone de
transmission 4 et amène celle-ci au contact du
mobile 5, le centre de rotation A du mobile 1 étant
alors légèrement décentré sur la droite.In Figure 1, the
La partie élastique peut être composée d'éléments souples tels que des mousses ou des ressorts. A l'aide des technologies modernes nous pouvons faire en sorte que cette partie soit souple, et néanmoins de dimension réduite.The elastic part can be composed flexible elements such as foams or springs. Using modern technologies we can make this part flexible, and nevertheless of reduced size.
Le mobile décentré peut même être décentré par intermittence en plein mouvement. Cela n'entraíne aucune modification de fonctionnement. Il peut également être décentré de manière permanente.The off-center mobile can even be off-center intermittently in full motion. it does not cause any modification of operation. he can also be permanently off-center.
Le fonctionnement du mobile 1 de la figure 1 sera expliqué en détail en regard de la figure 3.The operation of the mobile 1 of FIG. 1 will be explained in detail with regard to FIG. 3.
La figure 2 montre un des problèmes rencontré par les horlogers, dans lequel un axe traversant la platine d'une montre coïncide avec la périphérie d'un rouage du mouvement.Figure 2 shows one of the problems encountered by watchmakers, in which an axis crossing the platinum of a watch coincides with the periphery of a cog in the movement.
Lors de l'ajout sur un mécanisme existant
d'un module additionnel, il arrive souvent que l'axe
d'un mobile doive passer à travers toute la platine
pour, par exemple, une indication sur le cadran.
De ce fait, l'axe peut rencontrer un ou plusieurs
composants existants, par exemple le mobile 8
engrainant un autre mobile 9. Il survient alors de
nombreuses complications si l'on doit changer l'axe
de pivotement 7 de place. Cette situation a amené la
solution proposée pour parer à ce problème. Il
suffit de contraindre légèrement le mobile pour
éviter l'axe 7 , sans changer un seul entraxe, sans
altérer la fonction, et sans changer les rendements
des mobiles. When adding to an existing mechanism
of an additional module, it often happens that the axis
of a mobile must pass through the whole plate
for example, an indication on the dial.
Therefore, the axis can meet one or more
existing components, for example the mobile 8
causing another motive 9. It then arises from
many complications if you have to change the axis
pivoting 7 place. This situation has led to
proposed solution to deal with this problem. he
just slightly constrain the mobile to
avoid
Cette solution peut aussi compenser des problèmes moindres rencontrés en horlogerie, tels que les défauts de mal ronds des mobiles ou des problèmes d'arc-boutement entre les mobiles. Les défauts mineurs dus aux positionnements des trous de pivotement des différents mobiles peuvent aussi être facilement corrigés.This solution can also compensate for lesser problems encountered in watchmaking, such as that the roundness defects of the mobiles or problems of bridging between mobiles. The minor faults due to the positioning of the pivoting of different mobiles can also be easily corrected.
Dans la vue de la figure 3, le mobile 1 est
en contact avec un pont P ou une pièce quelconque
venant en contact avec la zone de transmission ou
un étagement solidaire de cette zone. La pression
exercée par le pont P, permet de solliciter
l'élasticité de la partie centrale en décentrant
uniquement la partie contenant la zone de
transmission. Celle ci reste en contact avec le
mobile suivant, et le positionnement théorique de
l'axe de pivotement A du moyeu 2 reste inchangé.In the view of Figure 3, the
Le principal avantage réside dans le fait
que le rapport de transmission ou le pas angulaire
est maintenu tout en étant décentré de son axe A de
pivotement. Pas besoin de changer le module ou
l'entraxe ou même le rapport. Il faut juste
contraindre le mobile pour qu'il soit en dehors de
la trajectoire à éviter. Il se peut aussi que ce
soit notre zone de transmission qui reste fixe, et
que le moyeu 2 soit décentré. Le pivotement
dépendrait alors de la bonne tenue axiale de la zone
de transmission 4, ce qui ne pose pas de problèmes
majeurs.The main advantage is that
that the transmission ratio or the angular pitch
is maintained while being off-center from its axis A of
pivoting. No need to change the module or
the center distance or even the relationship. You just have to
constrain the mobile to be outside
the trajectory to avoid. It may also be that
either our transmission zone which remains fixed, and
that the
Le mode d'exécution des figures 4 et 5 montre
un mobile 10 semblable au mobile 1 des figures 1 à
3, avec son moyeu 2, sa partie élastique 4, et sa
zone de transmission 4. Le mobile 10 est destiné à
engrainer un autre mobile 5 comme dans le mode
d'exécution précédent et l'ensemble représenté dans
les figures 4 et 5 fera fonction d'embrayage à
faible course.The embodiment of Figures 4 and 5 shows
a mobile 10 similar to the mobile 1 of FIGS. 1 to
3, with its
L'élasticité du mobile 10 est donc utilisée pour faire un embrayage à faible course, par exemple lors d'un compteur d'heures dans un calibre chronographe. Cette même élasticité peut être utilisée afin de garantir la pénétration des dentures avec des cliquets ou autres, tout en ménageant les pivots des mobiles. Dans la figure 4, l'embrayage est en position de repos, le mobile 5 n'étant pas entraíné, et le mobile élastique 10 pouvant tourner librement sur son axe A. The elasticity of the mobile 10 is therefore used to make a short stroke clutch, for example during an hour counter in a caliber chronograph. This same elasticity can be used to guarantee penetration of teeth with ratchets or others, while sparing the pivots of the mobiles. In Figure 4, the clutch is in the rest position, the mobile 5 not being driven, and the elastic mobile 10 can rotate freely on its axis A.
Dans la figure 5, le pont P subit une
translation, vient au contact du mobile 10, et
presse celui-ci contre le mobile 5 en déplaçant
l'axe de rotation A par une déformation de la zone
3. Le mobile 10 est alors en position d'embrayage.In Figure 5, bridge P undergoes a
translation, comes into contact with the mobile 10, and
press it against mobile 5 by moving
the axis of rotation A by a deformation of the
Dans le module d'exécution des figures 6 et
7, le mobile 20 avec son moyeu 2 , la partie
élastique 3, et sa zone de transmission 4, se
présente sous forme d'une étoile réalisant la
fonction d'un sautoir. La partie élastique 3 de
l'étoile 20 effectue la fonction habituellement
réalisée par une lame ressort. Un profilé 21 du
sautoir fait partie d'un pont P ou d'une noyure
fixe.In the execution module of Figures 6 and
7, the mobile 20 with its
L'étoile 20 avance ainsi d'un cran, ou d'un
pas, par une déformation de la zone élastique 3
comme représenté dans la figure 7, et l'étoile
revient en place après le passage d'une pointe
relativement au profilé 21.The
Toujours dans le domaine de l'horlogerie, le mobile 1, 10, ou 20, peut être utilisé comme anti-choc latéral pour toutes les applications horlogères. Still in the field of watchmaking, the mobile 1, 10, or 20, can be used as anti-shock lateral for all applications watchmaking.
Dans le mode d'exécution des figures 8 et 9,
le mobile 30 comprend un moyeu 2, une zone élastique
3 formée d'une succession de lamelles concentriques
31 solidaires du moyeu 2 et de la zone de
transmission 3. Comme mentionné plus haut, le mode
d'exécution des figures 8 et 9 n'est pas uniquement
destiné au domaine horloger, mais peut s'adapter à
d'autres applications tels que les suspensions des
véhicules par exemple. En effet, ce système adapté
verticalement et directement sur les roues, peut
encaisser des chocs de tous genres et de toutes
directions.In the embodiment of Figures 8 and 9,
the mobile 30 comprises a
