Definitions

  • the present invention relates to an exhaust system.
  • This exhaust system comprises an anchor provided with a fork intended to cooperate with a pin mounted on a plate, and a rod comprising arms intended to receive pallets in order to cooperate with at least one escape wheel.
  • the technical field of the invention is the technical field of fine mechanics, and more particularly of watchmaking
  • the timepieces include a power source such as the barrel providing energy to the room and in particular to the gear wheels. These wheels cooperate with the exhaust system via the escape wheel.
  • the rotation of the latter is regulated by the anchor of the exhaust system whose pulses are provided by the balance spring.
  • the exhaust system includes an anchor pivotally mounted on an axle.
  • This anchor comprises a rod provided with a fork, at a first end, intended to cooperate with a pin mounted on a plate, and provided with arms, at a second end, intended to receive pallets in order to cooperate with the wheel. exhaust.
  • the anchor pivots on its axis so that the paddles of the arms come into contact with the teeth of the escape wheel in order to regulate the rotation of the wheels.
  • the efficiency of the exhaust is relatively low.
  • the operation of the exhaust system comprises friction, shock and dissipation of energy in the materials components of the wheel and the anchor in particular.
  • a material used is for example 15P or 20AP steel. These materials are crystalline materials Gold, a disadvantage of crystalline metal components is their low mechanical strength when high stresses are applied. Indeed, each material is characterized by its Young's modulus E also called modulus of elasticity (generally expressed in GPa), characterizing its resistance to deformation. Each material is also characterized by its elastic limit ⁇ e (generally expressed in GPa) which represents the stress beyond which the material deforms plastically.
  • the efficiency of an escapement is related to the energy restitution factor during shocks, these shocks being the shocks between the pallets of the anchor of the escape wheel and the shocks between the ankle of the plate and the fork entrance.
  • the kinetic energy accumulated during the displacement of the anchor or the escape wheel is dependent on the moment of inertia which is a function of the mass and the radius of inertia, and therefore dimensions.
  • the maximum energy that can be stored elastically is calculated as the ratio between the square of the elastic limit ⁇ e on the one hand and the Young's modulus E on the other hand, the low elastic limit of the crystalline metals leads to a low level of energy storage capacity.
  • the steels 15P or 20AP are dense and therefore the anchors and escapement wheels have high masses. The moment of inertia is then high and the kinetic energy accumulated during the movements of the anchor and the escape wheel is important.
  • watchmaking traditionally uses hardened sulfur-lead carbon steels that offer good machinability and very good mechanical properties, but which are magnetic.
  • Non-magnetic alternatives are rare and generally more difficult to machine and offer poorer mechanical properties.
  • the invention aims to overcome the disadvantages of the prior art by proposing to provide an exhaust system with higher efficiency and simpler to achieve.
  • the invention relates to the exhaust system cited above which is characterized in that at least a portion of the exhaust system is made of an at least partially amorphous material and comprising at least one metal element.
  • a first advantage of the present invention is to allow the exhaust system to have a better energy restitution factor than current exhausts.
  • an amorphous metal is characterized by the fact that, during its manufacture, the atoms composing these amorphous materials do not arrange according to a particular structure as is the case for crystalline materials.
  • a Amorphous metal is then differentiated by an elastic limit ⁇ eA higher than ⁇ eC of the crystalline metal by a factor of two to three.
  • the elastic limit ⁇ e is increased making it possible to increase the ratio ⁇ e / E so that the stress limit beyond which the material does not return to its initial shape increases, and especially so that the maximum energy that can be stored elastically increases.
  • Another advantage of the present invention is to allow great ease in shaping allowing the development of complicated shapes with greater precision.
  • the amorphous metals have the particular characteristic of softening while remaining amorphous for a certain time in a given temperature range [Tg - Tx] specific to each alloy (with Tx: crystallization temperature and Tg: glass transition temperature ). It is thus possible to shape them under a relatively low pressure stress and a low temperature then allowing the use of a simplified process compared to machining and stamping.
  • the exhaust system 1 comprises a Swiss anchor 7 formed by a main face (visible to the figure 1 ) in projection.
  • the Swiss anchor 7 is mainly formed by a rod 9 connecting the fork 11 and the arms 13.
  • the fork 11 comprises two horns 15 opposite each other which is mounted on a stinger 17 in order to cooperate respectively with a pin fixed on said plate 5 of the balance shaft and the lower part of said plate 5.
  • the rod 9 receives, between the two arms 13, a rod 19 for rotating the anchor between a bridge and the plate of the movement.
  • a pallet 21 intended to come into contact with the escape wheel 23 via its teeth 25.
  • the pallets may, for example, be formed of synthetic ruby.
  • the present invention may also be used for the type coaxial escapement as in watchmaking.
  • At least a part of the exhaust system 1, that is to say the plate 5 or the anchor 7 or the escape wheel 23 is made of an at least partially amorphous material comprising at least a metallic element.
  • This metal element may be valuable such as gold, platinum, palladium, rhenium, ruthenium, rhodium, silver, iridium or osmium. It will be understood by at least partially amorphous material that the material is capable of solidifying at least partially in the amorphous phase.
  • all parts of the exhaust system 1 are made of at least partially amorphous material comprising at least one metal element. Nevertheless, these parts can be made of different amorphous materials.
  • amorphous metal alloys comes from the fact that, during their manufacture, the atoms composing these amorphous materials do not arrange in a particular structure as is the case for crystalline materials. Thus, even if the Young E moduli of a crystalline metal and an amorphous metal are substantially identical, their elastic limits ⁇ e are different. An amorphous metal is then differentiated by an elastic limit ⁇ eA higher than that ⁇ eC of the crystalline metal by a factor substantially equal to two. A higher elastic limit therefore means that a piece of amorphous metal alloy or amorphous metal deforms plastically under a higher stress than the same piece of crystalline metal.
  • the losses of an exhaust system 1 are related to the friction between the pallets 21 of the anchor 7 and the teeth 25 of the escape wheel 23 during the training phase and to the shocks between the teeth 25 of the escape wheel 23 and the pallets 21 of the anchor 7 during the fall phase.
  • the losses due to shocks between the teeth 25 of the escape wheel 23 and the pallets 21 of the anchor 7 during the fall phase are a function of the kinetic energy.
  • This kinetic energy, accumulated during the operation of the exhaust system 1, is dependent on the moment of inertia.
  • This moment of inertia is a function of the mass and the radius of inertia.
  • the maximum specific resistance is of the order of 200-250 MPa * cm 3 / g.
  • the specific resistance of the amorphous alloys is of the order of 300-400 MPa * cm 3 / g.
  • Another solution is to reduce the mass of the part by removing material, preferably in the areas contributing most to the moment of inertia, that is to say in the parts furthest from the axis of rotation of the room. It is possible, for example, to make recesses 29, crossing or not, and / or to locally reduce the thickness 27 of the part.
  • an amorphous alloy having a mechanical strength greater than the crystalline alloy will be chosen. Given the advantageous specific resistance of the amorphous alloys, the density of the amorphous alloy may be chosen to be equal to or slightly less than that of the crystalline alloy and consequently the moment of inertia of the system 1 will be decreased.
  • a third possibility is to reduce the dimensions of the elements of the exhaust system 1 such as the anchor 7 or the wheel 23 or the plate 5.
  • this decrease dimensions and mass do not cause a decrease in the mechanical strength of the exhaust system 1.
  • the specific resistance of the amorphous alloys being greater in comparison with the crystalline alloys, the density of the amorphous alloy chosen may be equal to or less than that of the crystalline alloy used for the standard part, and consequently the moment of inertia and the size of the system 1 may be reduced.
  • the exhaust system 1 which are metal or amorphous metal alloy. This makes it possible to keep the same size as an exhaust system 1 made of crystalline material and thus to keep standard dimensions while having a better resistance to stresses.
  • the use of such a material also makes it possible to reproduce fine geometries very precisely because the viscosity of the alloy decreases sharply as a function of the temperature in the temperature range [Tg-Tx] and the alloy thus allies the details of the negative.
  • the shaping is done around 300 ° C for a viscosity up to 10 3 Pa.s for a stress of 1 MPa, instead of a viscosity of 10 12 Pa. s at the temperature Tg.
  • the use of dies has the advantage of creating three-dimensional pieces of high precision, which can not be cut or stamped.
  • One method used is the hot forming of an amorphous preform.
  • This preform is obtained by melting the metal elements intended to constitute the amorphous alloy in a furnace. Once these elements are melted, they are cast as a semi-finished product, then cooled rapidly to maintain the at least partially amorphous state. Once the preform is made, the hot forming is performed in order to obtain a final piece. This hot forming is performed by pressing in a temperature range between its glass transition temperature Tg and its crystallization temperature Tx for a predetermined time to maintain a totally or partially amorphous structure. This is done in order to maintain the characteristic elastic properties of the amorphous metals.
  • the elements of the exhaust system can be made by casting or injection. This process involves casting the alloy obtained by melting the metal elements in a mold having the shape of the final piece. Once the mold is filled, it is rapidly cooled to a temperature below Tg in order to avoid crystallization of the alloy and thus obtain a system 1 of amorphous or partially amorphous metal.
  • pallets 21 of the anchor 7 are made of metal or amorphous alloy. These pallets 21 can form one and the same piece with said anchor or be overmolded after manufacture of the anchor 7. It then becomes possible that the pallets 21 and the anchor 7 are made of metal or amorphous alloy but different from each other. one of the other.
