Definitions
- the present invention relates to a ferrule, made in one piece with the spiral of a sprung-balance balance system of a clockwork mechanical movement, and whose shape has been studied to minimize the risk of breakage at the ferrule-spiral junction. case of shock.
- the balance-sprung adjusting system constitutes one of the most fragile parts of the mechanism, in particular in the event of shocks that can cause the tigerons of the balance shaft to rupture, or even the rupture of the spiral at the level of the junction ferrule-spiral.
- shock absorbing bearings such as the landing called "Incabloc”.
- Such damping bearings also help to protect the hairspring but are insufficient when an impact causes a large clearance of the hairspring and creates a tension at the junction ferrule-curve inside the hairspring.
- the risk of breakage at this junction is greater when the curve inside is of the Grossmann type with a ring-shaped shell, that is to say when the first turn of the curve inside has a no larger than that of the following turns, making the space between this first turn and the ferrule is relatively large.
- the risk of rupture is further increased when the hairspring is made of a brittle material, such as silicon, monocrystalline quartz or glass, and / or when it is made in one piece at the same time as the ferrule by techniques of micromachining techniques or by photolithography and galvanic growth, as described in patent EP 1 445 670.
- the present invention therefore aims to overcome the disadvantages of the aforementioned prior art by providing, for a spiral balance adjusting system, a ferrule whose particular contour makes it possible to minimize the risk of rupture at the ferrule-spiral junction in the event of violent shocks.
- the subject of the invention is an impact-resistant shell formed of a plate comprising an opening for its attachment to a balance shaft of a balance-balance and balance-fixing system of a balance spring.
- ferrule is characterized in that it has a non-circular asymmetric contour which follows at least space in place at a small distance d_ substantially constant the contour of the first turn of the curve inside.
- the outline of the shell may be continuous or scalloped. In the latter case the distance d_ is the distance between the first turn of the ends of the festoon teeth.
- This construction has the advantage of limiting the deflection of the first turn during violent shocks, and thereby significantly reduce the risk of rupture at the junction ferrule-spiral, especially when the ferrule is made of a sensitive brittle material impact, which will be more particularly illustrated in the following description by a material such as silicon, quartz or glass,
- Virollage can be achieved by any known means such as a pin-like flange or laser welding.
- the ferrule and the spiral are made in one piece. It will be observed that the asymmetric contour of the ferrule creates an imbalance that the center of gravity of the ferrule or the ferrule-spiral assembly does not coincide with the balance axis, which has a negative effect on isochronism.
- the plate forming the ferrule comprises recesses whose surfaces and distribution are chosen to reposition said center of gravity on the balance shaft. These recesses can further communicate with the hunting opening to give it a certain elasticity.
- FIG. 1 shows a first embodiment
- FIG. 3 represents a third embodiment
- FIG. 4 shows a fourth embodiment.
- the ferrule and the spiral form a single piece made of the same material Recent technologies well known to those skilled in the art allow in fact to achieve almost any contour with great precision and with a high aspect ratio. If the material used is a metal or an alloy, the technique of photolithography and electroforming will be used. If the material used is an amorphous or crystalline material, such as glass, quartz or silicon, using a micro-machining process, already used for example in the manufacture of integrated circuits, will be used.
- FIG. 1 represents a first embodiment of a shell made in one piece at the same time as the spiral 7, that is to say without discontinuity of material at the junction 2 between the plate 1 of the shell and the first turn 1 1 of the curve inside.
- the plate 1 has an opening 3 for fixing the ferrule on the balance shaft 5.
- contour 9 follows at a substantially constant distance d_ the inner contour of the first turn 11, that is to say the turn which starts from the junction 2 and which makes a complete turn to find itself radially at the same level that said junction 2.
- the outline of the ferrule is not continuous and has a scalloped shape having a succession of grooves 10 and teeth 12 whose ends are at the distance d_ from the first turn 1 1.
- Figure 3 shows how it is possible to eliminate the aforementioned drawback.
- the center of gravity g. can be repositioned on the balance shaft 5 forming in the plate 1 of the ferrule recesses 13 whose surfaces decrease in the opposite direction of the coil winding.
- these recesses 13 may also be joined.
- the distribution and surfaces of these recesses are computational - AT -
- FIG. 4 shows a third embodiment which differs from the previous embodiment in that the recesses 13 communicate through through-passages 15 with the opening 3, recesses and passages being further distributed in order to refocus the center of gravity of the ferrule-spiral assembly.
- This construction also has the advantage of providing a certain elasticity to the driving opening, which is particularly useful when the material used to make the ferrule-spiral assembly is a brittle material, such as glass, quartz or silicon.
- the ferrule when the ferrule has a scalloped contour, it is possible to reposition the center of gravity g. the ferrule or the ferrule-spiral assembly on the balance shaft by gradually increasing the depth of the recesses 12 between the teeth 10 as one moves away from the function 2 between the spiral and the ferrule .
