Definitions

  • the invention relates to a TourbiUon, or a tourbillon module, according to the preamble of the independent claim.
  • Movements with a TourbiUon are known from the prior art, which are generally of complex construction. This creates disadvantages in production and maintenance. In addition, there is no way to achieve a TourbiUon with a particularly flat structure.
  • TourbiUon is mounted in front of a barrel. This structure is very complex in terms of assembly and maintenance and therefore expensive. In the event of a defect in particular, it is necessary to dismantle the entire movement in order to gain access to the TourbiUon. The TourbiUon is also only visible from the front.
  • the object of the invention disclosed here is to show a TourbiUon, or a tourbillon module with a maintenance-friendly, simple structure and improved accuracy, which if necessary has a particularly low overall height of the tourbillon.
  • the TourbiUon according to the invention preferably has a modular structure.
  • the actual tourbillon mechanism, including all essential parts, are preferably combined in a tourbillon module, which has a standardized interface to the rest of the movement and can be detached from it in a simple manner.
  • the TourbiUon preferably has a platform that is supported on one side (flying TourbiUon).
  • a ball bearing (main bearing) is preferably used for the storage, the outer ring of this ball bearing also rotating with the platform of the tourbillon.
  • the platform and the outer ring can be formed in one piece if necessary.
  • the inner ring of the central bearing of the platform is fixed to a base and does not rotate. So that the bearing play can be easily adjusted, it is possible to design the inner and / or the outer ring in two parts.
  • a balance is supported by an upper and a lower balance bearing. In certain embodiments, both balance bearings rotate with the platform. Alternatively, there is the option of arranging the lower balance bearing fixed on the side of the base. Depending on the design, this has an advantageous effect on the overall height.
  • the tourbillon constructions known from the prior art generally have the disadvantage that it is not possible to adjust and maintain the tourbillon or the bearings of the tourbillon in the installed state. If a TourbiUon is to be serviced, the entire movement must usually be dismantled.
  • the TourbiUon disclosed here has a structure that enables easy maintenance.
  • the bearings are preferably arranged so that they can be easily checked, adjusted and serviced even when installed. So that both a lower bearing of the balance (balance bearing) and the main bearing of the platform of the tourbillon are freely accessible, the inner ring of the main bearing of the platform preferably has a diameter that is so large that the lower bearing of the balance (balance bearing) in it Mitte finds space and is accessible when needed, especially for maintenance purposes.
  • a coaxial arrangement ensures that forces due to external shocks and impacts are dissipated particularly efficiently.
  • a further advantage is that the balance bearings can be arranged far apart in a coaxial arrangement, so that the balance axis has a comparatively maximum length, whereby the reaction forces due to occurring moments are comparatively minimized.
  • manufacturing tolerances generally have less influence.
  • the invention enables very flat tourbillons to be built, the height of which is less than 5 mm and, if necessary, less than 4 mm.
  • the means for mounting the tourbillon platform (for a ball bearing, the balls) are preferably arranged approximately at the level of the main level of the tourbillon platform.
  • the tourbillon platform assigns a correspondingly large opening for this purpose.
  • the outer ring of the main bearing of the platform is preferably integrated into the platform.
  • the means for mounting the tourbillon platform come to lie approximately at the level of the base, the outer ring of the main bearing being stationary and the inner ring being arranged in a rotating manner.
  • the balls of the main bearing are arranged approximately at the level of the platform or the base, it makes sense to arrange the lower bearing of the balance inside the main bearing coaxially on the fixed side (clockwork side). This further reduces the overall height if necessary.
  • the lower bearing of the balance wheel and the main bearing of the platform of the tourbillon are preferably arranged essentially coaxially, since mechanical shocks and vibrations are thereby particularly well dissipated.
  • an industrial warehouse can also be used.
  • this increases the number of parts and, depending on the embodiment, the bearing play cannot be optimally adjusted.
  • Finished bearings are preferably attached by pressing or gluing.
  • Figure 1 shows a first embodiment of a tourbillon module in a plan view.
  • FIG. 2 shows a section through the tourbillon module according to FIG. 1;
  • FIG. 3 shows a second embodiment of a tourbillon module in a perspective view
