Description
Palier pare-chocs pour pivot de balancier de mouvement d'horlogerie. _Le palier pare-chocs, objet de la présente invention, est destiné à, un pivot de balancier d'un mouvement d'horlogerie tournant dans un coussinet. métallique. Dans le cas particu lier, ce coussinet est maintenu librement à l'intérieur du coqueret par un bras faisant ressort et traversant aussi bien le coqueret que la serge de la raquette dans des décou pures prévues à cet effet. On obtient de cette manière un tout susceptible d'absorber aussi bien les composantes radiales que les compo santes axiales des chocs que reçoit la montre et ceci au moyen d'organes dont le coût mi nime peut encore être supporté par le prix de vente de mouvements du genre précité.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution du palier selon la présente invention.
La fig. 1 en est une vue en plan, tandis que la fig. 2 en est une coupe selon la ligne II-II de 1 a fig. 1.
1 désigne la planche du coq du mouvement sur lequel le palier pare-chocs est, monté et sur laquelle le coqueret 2 est maintenu au moyen de vis 3. Autour du coqueret tourne la. raquette 4. Coqueret et raquette ont une dé coupure ou solution de continuité à travers lesquelles passe un ressort 5 ondulé paral lèlement au coq auquel il est fixé par une vis 6, et présentant, à son extrémité une bague 7 fendue et dans laquelle est. maintenu suspendu le coussinet 8 portant le eontre-pivot 9.
Le ressort 5 absorbe aussi bien les compo santes radiales que les composantes axiales des choc que reçoit la montre dans laquelle le palier pare-chocs est monté. Ce serait aussi le cas si ce ressort 5 reposait sur le coq sur toute sa. longueur.
Bumper bearing for clockwork movement balance pivot. _The bumper bearing, object of the present invention, is intended for a balance pivot of a clockwork movement rotating in a bearing. metallic. In the particular case, this pad is held freely inside the cockle by an arm making a spring and crossing both the cockpit and the rim of the racket in cutouts provided for this purpose. In this way, a whole is obtained which is capable of absorbing both the radial components and the axial components of the shocks that the watch receives and this by means of members whose minimal cost can still be borne by the selling price of movements. of the aforementioned kind.
The appended drawing shows, by way of example, an embodiment of the bearing according to the present invention.
Fig. 1 is a plan view thereof, while FIG. 2 is a section along the line II-II from 1 to fig. 1.
1 designates the board of the movement cock on which the bumper bearing is mounted and on which the cockerel 2 is held by means of screws 3. Around the cockle rotates. racket 4. Coqueret and racket have a cut or solution of continuity through which passes a corrugated spring 5 parallel to the cock to which it is fixed by a screw 6, and having, at its end a split ring 7 and in which is. kept suspended the bearing 8 carrying the counter-pivot 9.
The spring 5 absorbs both the radial components and the axial components of the shocks received by the watch in which the bumper bearing is mounted. This would also be the case if this spring 5 rested on the cock over its entire length. length.
