Definitions

  • the present invention relates to a tourbillon mechanism for improving the running accuracy of the regulating member and more specifically to improving the mechanical construction of such a mechanism leading to a greater positioning accuracy of the parts forming these mechanisms.
  • Tourbillon mechanisms are known from the first device of this kind devised by A.-L. Breguet in 1801 in a variety of forms of execution.
  • Such a mechanism comprises a cage pivotally mounted in the housing of the timepiece concerned, this cage carrying all the exhaust members and the regulating member. Due to the above-mentioned complexity and purpose of such a mechanism, all elements of a vortex mechanism must be positioned as accurately as possible.
  • the anchor and the escape wheel are subject to possible improvements concerning inter alia their positioning relative to each other using the cage, or even on an element attached to the latter, this in to increase the accuracy of this positioning and guidance of the elements during operation of the mechanism.
  • the object of the present invention is to overcome the aforementioned drawbacks and to allow the realization of a simple vortex mechanism with a number reduced weight and parts at the same time ensuring the concentricity of the elements and the rigidity of the cage as well as guaranteeing the easy and precise positioning of the anchor and the escape wheel on the cage simultaneously ensuring a better guidance of those -this.
  • the object of the present invention is therefore a vortex mechanism distinguished by the features set forth in claim 1 and the dependent claims.
  • the drawing illustrates schematically and by way of example an embodiment of a tourbillon mechanism according to the present invention.
  • the figure 1 shows the cage of the tourbillon mechanism and the elements mounted on the cage, specifically a monolithic bridge for mounting the anchor and the escape wheel.
  • the Figures 2a and 2b show cuts of the cage along line AA of the figure 1 once in plan and once in perspective.
  • the figure 3 is a perspective view of the monolithic bridge for the positioning of the escape wheel and the anchor.
  • a vortex mechanism comprises, as shown schematically in FIG. figure 1 , a cage 1 which is pivotally mounted around a pinion 2 in the housing of the timepiece for which it is intended.
  • this cage comprises an upper part 1a and a lower part 1b intended to be superimposed on each other in order to form the cage 1.
  • the solution envisaged by the present invention ensures the equidistance of the two planes of the upper parts 1a and lower 1b as well as their concentricity and coaxiality all along their length. periphery. While decreasing the number of pieces forming the cage 1 of the mechanism and, therefore, by facilitating the assembly of the cage 1, its rigidity is higher compared to the conventional solution known at this time.
  • the assembly of the cage is done by means of the cylindrical skirts of the upper parts 1a and lower 1b, that is to say walls substantially forming a cylinder body, these cylindrical skirts being adapted to be associated to form the entire cage.
  • Positioning elements 1c of different shapes can provide the desired orientation and positioning of the upper parts 1a and lower 1b one on the other.
  • these positioning elements 1c are made by equipping the cylindrical skirts of the upper part 1a and lower 1b at their end oriented in the center of the cage 1 with a radial narrowing, one inside and the other outside as at Figures 2a and 2b , so that the two parts 1a and 1b fit together and are positioned precisely relative to each other and relative to the axis of the balance.
  • These two parts 1a and 1b are therefore guided as regards their positioning by their cylindrical skirts and more specifically by their positioning elements 1c or interlocking formations, that is to say by elements concentric to the axis of the cage 1, so that the axis of the cage 1 is perfectly aligned on the same axis as the balance, thus defining an optimum concentricity.
  • the fixing of these parts can be done by means of different solutions, for example using screws 1d placed in orifices provided for this purpose in the cylindrical skirts of the upper parts 1a and lower 1b; the skirts may be locally thicker at the locations provided with these orifices intended to receive the screws 1d, these skirts preferably joining the decks of the cage also coming from a workpiece with said skirts carrying the other elements which are not important in the context of the present invention and will not be described in detail here.
  • the two parts 1a, 1b of the cage are made of an aluminum alloy treated with anodic oxidation. In addition to the rigidity of this material and the advantages derived therefrom, this makes the cage also lighter than a cage conventionally matched with the usual three pillars.
  • the present invention guarantees several advantages, even a reduced number of parts and easy assembly of the cage 1, a reduced weight, high rigidity and above all improved precision in terms of the concentricity of the parts forming the cage 1 and elements mounted on the latter relative to the axis of the balance.
  • a tourbillon mechanism comprises a cage 1 associated with a monolithic bridge 7, that is to say in one piece, which ensures the positioning of an escape wheel 3 and simultaneously of an anchor 5 and which is schematically illustrated at the figure 3 .
  • the monolithic bridge 7 preferably has substantially the shape of a circular segment which bypasses the elements in the center of the cage and which is equipped with orifices and housings. This monolithic bridge 7 is concentric with the axis of the cage 1 of the vortex.
  • the escape wheel 3 is pivotally mounted around a pinion of the escape wheel 4, the anchor 5 is mounted around an anchor rod 6.
  • These two supplies 4 and 6 are both mounted, in the case shown in figure 1 at their upper end, on the monolithic bridge 7 in two bearings 7b and 7c receiving the pivots of the anchor and the escape wheel so that the anchor 5 can work with the escape wheel for operation normal of a vortex mechanism which will not be described in more detail later, because this operation is not essential for the invention.
  • this monolithic bridge 7 may comprise a pinion bearing 7b designed to accommodate the pivot of the exhaust pinion which is intended to mesh with still other wheels.
  • the fact mounting the anchor 5 and the escape wheel 3 on a monolithic bridge improves the accuracy of their mutual positioning and guidance. In addition, such a system makes the tourbillon mechanism and its cage 1 equipped with this monolithic bridge 7 more compact.
  • the fixing of the monolithic bridge 7 to the cage 1 is also preferably done by means of screws housed in orifices 7a provided for this purpose at both ends of the monolithic bridge 7 and corresponding threads formed in guide tubes themselves. hunted in the arms of the upper part of the cage 1.
  • the whole of the cage 1 associated with the monolithic bridge 7 makes it possible to ensure an improved accuracy compared to the state of the art as regards the concentricity of the axis of the cage 1 and the balance and the positioning of the the escape wheel 3 and the anchor 5 and thus contributes to improving the running accuracy of the regulating member.
  • the monolithic bridge 7 could be used with a conventional tourbillon cage screwed pillars for fixing the upper and lower cages.
  • the cage 1 with interlocking cylindrical skirts can be used with two bridges, one for the anchor journaling and the other for that of the escape wheel.
