Abstract

The invention relates to the fixing of the rotor of the electric motor of an electronic movement of a watch making it possible to remove this rotor from the bottom plate of the watch without dismantling the train bar. The fixing device for the rotor 1 of the electric motor 2 comprises a pivot 4 which is housed in the train bar 5 of the movement and a pivot 8 whose housing 7 in the bottom plate 6 is open and increased to a diameter greater than that of the rotor 1 and closed by a bearing 10 in order to hold the rotor 1 in place and housed in a cover 9. When, during functioning of the watch, microscopic ferrous impurities are deposited around the rotor 1 and slow down the free running of the rotor until it is immobilised, the application of the invention avoids the dismantling of all the parts of the clockwork movement in order to remove this rotor 1 for cleaning thereof, but the most advantageous application of the invention is illustrated during maintenance when the freeing of the microscopic ferrous impurities by the maintenance liquids renders removal of the rotor for cleaning thereof obligatory.

Description

La présente invention concerne' la fixation du rotor du moteur électrique dtun mouvement électrique d'une montre:, permettant de sortir ce rotor de la platine de la montre sans démontage du pont de rouage, pour faciliter ainsi son entretien. The present invention relates to the fixing of the rotor of the electric motor to an electric movement of a watch:, allowing this rotor to be removed from the plate of the watch without removing the gear train, thereby facilitating its maintenance.

Dans les montres connues de ce genre, le pont de rouage fixé par plusieurs vis sur la platine, contient un logement pour une de deux dparties de l'axe du reter. Une: telle disposition de logement rend l'entretien de la montre: malaisé., chose encore aggravée lors du- nettoyage sans démontage préalable de la montre. En effet, par sa nature d'être un aimant permanent, le rotor attire toutes les particules microscopiques ferreuses, non-dissoutes par le liquide. In known watches of this kind, the cog bridge fixed by several screws on the plate, contains a housing for one of two parts of the reter axis. One: such a housing arrangement makes the maintenance of the watch: awkward, something even worse during cleaning without disassembling the watch beforehand. In fact, by its nature of being a permanent magnet, the rotor attracts all microscopic ferrous particles, not dissolved by the liquid.

Ces particules microscopiques ferreuses bouchent l'espace entre le roter et le stator du moteur électrique jusqu'à son blocage. Pour y remédier, il est nécessaire d'enlever le pont de rouage pour pouvoir sortir ledit rotor en vue de son nettoyage. These microscopic ferrous particles block the space between the rotor and the stator of the electric motor until it blocks. To remedy this, it is necessary to remove the gear train in order to be able to remove said rotor for cleaning.

Be dispositif de fixation de ce rotor selon l'invention permet d'éviter cet inconvénient. Le logement d'une de deux parties de l'axe du rotor est en effet ouvert d'une telle mani8re que le rotor peut titre sorti de son emplacement sans qutil soit nécessaire d'enlever tout le pont de rouage. Afin de maintenir en place: le rotor dans sa position, cette ouverture est fermée par un cou- verole contenant le: coussinet pour l'axe du rotor. Be fixing device of this rotor according to the invention avoids this drawback. The housing of one of two parts of the axis of the rotor is in fact opened in such a way that the rotor can rightly come out of its location without it being necessary to remove the entire gear train. In order to keep in place: the rotor in its position, this opening is closed by a cover containing the: bearing for the axis of the rotor.

Selon une première variante, ce couvercle est maintenu en place par un ressort sdéquet, facilement à enlever et à remettre. According to a first variant, this cover is held in place by a sequential spring, easily removed and replaced.

Selon une deuxième- variante', ce couvercle est maintenu par une bride élastique, fixés par exemple par une via du tout autre moyen. According to a second variant, this cover is held by an elastic flange, fixed for example by a via of any other means.

Le dispositif selon ltinvention permet, en enlevant le' couvercle de l'ouverture de libérer le rotor de son emplacement et de' le- retirer pour son nettoyage, sans qu'il soit; necessaire d'enlever tout la pont: de rouage. The device according to the invention makes it possible, by removing the 'cover of the opening, to free the rotor from its location and to' remove it for cleaning, without it being; necessary to remove the entire bridge: cog.

La dessin annexé est une vue en coupe du dispositif, lorsque le moyen de- fixation du couvercle est un ressort. The accompanying drawing is a sectional view of the device, when the means for fixing the cover is a spring.

Tel qutil est représenté le rotor 1 du moteur électrique 2 qui comporte sur sa partie supérieure la roue dentée d'entraîne- ment 3, est logé par son pivot 4 dans le pont de' rouage' 5 qui à son tour est fixé par plusieurs vie sur la platine du mouvement. As shown, the rotor 1 of the electric motor 2 which has on its upper part the toothed drive wheel 3, is housed by its pivot 4 in the 'gear train' bridge 5 which in turn is fixed by several life on the movement stage.

Dans la platine du mouvement 6 le logement 7 du pivot: B est ouvert dtune manière que le rotor 1 peut être facilement sorti, sans qu'il est nécessaire d'enlever le pont de rouage 5. Pour maintenir le pivot 8 dans sa place, le logement 71 du pivot 8 est fermé par un couvercle: 9 qui comporte un coussinet 10 à son intérieur. Le couvercle 9 est tenu en place par un ressort adéquat 11 sur la platine du mouvement 6. In the movement plate 6 the housing 7 of the pivot: B is open in such a way that the rotor 1 can be easily removed, without it being necessary to remove the gear train 5. To keep the pivot 8 in its place, the housing 71 of the pivot 8 is closed by a cover: 9 which has a pad 10 inside. The cover 9 is held in place by a suitable spring 11 on the plate of the movement 6.

Quand au cours de fonctionnement de la montrez et notamment pendant l'entretien de la montre, les impuretés mieressopiques ferreuses se posent autour du rotor 1, freinant; ainsi la libre marche du rotor jusqu'à son blo-cage total, au lieu de devoir démonter toutes les parties du. mouvement d'horlogerie pour sortir ce rotor 1 en vue de son nettoyage, on n'enlève que le couvercle 9 de la platine du mouvement 6 qui permet la libre sortie du rotor 1.  When during operation of the watch and in particular during the maintenance of the watch, the ferrous mieressopic impurities arise around the rotor 1, braking; thus the free running of the rotor until its total block, instead of having to dismantle all the parts of the. clock movement to remove this rotor 1 for cleaning, only the cover 9 of the movement plate 6 is removed, which allows the rotor 1 to be freely removed.
