Definitions

  • the subject of the invention is a mobile intended to come into contact with another mobile or fixed element.
  • the mobile according to the invention is characterized in that it comprises a hub rotating on its axis, and a transmission or rolling area intended to come into contact with the mobile or fixed element, an elastic zone likely to undergo a deformation being interposed between the hub and the transmission area.
  • the area elastic may be a deformable foam, or be constituted by a succession of lamellae connecting the hub at the transmission or bearing area.
  • the transmission or rolling area can take the form of a gear wheel.
  • the mobile according to the invention can be submitted at a pressure exerted by a bridge or a stage applied to the transmission area, the pressure exerted by the bridge bringing the mobile into contact another mobile to train by deforming the area elastic and by moving the axis of rotation of said mobile.
  • Mobile can be used as part component of a clutch.
  • the transmission area of the mobile can present a succession of teeth abutting against a profile of a fixed bridge or recess, the advance of a step or a tooth being produced by the deformation of the elastic area of the mobile.
  • the mobile can be in the form of a star
  • the transmission area of the mobile can be arranged to produce a bearing or a friction drive.
  • the invention also for object a use of the mobile in the mechanics in general, especially in automotive, aviation, medicine, etc.
  • the attached drawing represents, as example, several modes of execution of a mobile likely to be off-center from its axis.
  • the mobile described in the different modes was developed for industry watchmaking. However, its application is not limited to this particular area, and may be extended to mechanics in general, in particular to automotive, aviation, micro-mechanics, the machine tool, medicine, and all technical fields in which a mobile must be brought into contact with a mechanical element fixed or mobile, by a deformation of the structure corresponding to a displacement of sound center of rotation.
  • the mobile represented in the different execution modes was developed for industry
  • the mobile represented in the embodiment of the Figure 1 allows, once in place, to generate with another mobile or any other kind of transmission by being off-center from its axis of pivoting A.
  • the mobile 1 generates a other mobile 5, and is driven by a pinion 6, which exerts lateral pressure on the area of transmission 4 and brings it into contact with the mobile 5, the center of rotation A of mobile 1 being then slightly off-center on the right.
  • the elastic part can be composed flexible elements such as foams or springs. Using modern technologies we can make this part flexible, and nevertheless of reduced size.
  • the off-center mobile can even be off-center intermittently in full motion. it does not cause any modification of operation. he can also be permanently off-center.
  • Figure 2 shows one of the problems encountered by watchmakers, in which an axis crossing the platinum of a watch coincides with the periphery of a cog in the movement.
  • This solution can also compensate for lesser problems encountered in watchmaking, such as that the roundness defects of the mobiles or problems of bridging between mobiles.
  • the minor faults due to the positioning of the pivoting of different mobiles can also be easily corrected.
  • the mobile 1 is in contact with a P bridge or any part coming into contact with the transmission area or an integral tiering of this area.
  • Pressure exerted by bridge P allows to solicit the elasticity of the central part by decentering only the part containing the area of transmission. This remains in contact with the next mobile, and the theoretical positioning of the pivot axis A of the hub 2 remains unchanged.
  • the main advantage is that that the transmission ratio or the angular pitch is maintained while being off-center from its axis A of pivoting. No need to change the module or the center distance or even the relationship. You just have to constrain the mobile to be outside the trajectory to avoid. It may also be that either our transmission zone which remains fixed, and that the hub 2 is off-center. The pivoting would then depend on the good axial behavior of the area 4, which is fine major.
  • FIGS. 4 and 5 shows a mobile 10 similar to the mobile 1 of FIGS. 1 to 3, with its hub 2, its elastic part 4, and its transmission zone 4.
  • the mobile 10 is intended for generate another mobile 5 as in the mode previous execution and the set represented in Figures 4 and 5 will act as a clutch to weak stroke.
  • the elasticity of the mobile 10 is therefore used to make a short stroke clutch, for example during an hour counter in a caliber chronograph. This same elasticity can be used to guarantee penetration of teeth with ratchets or others, while sparing the pivots of the mobiles.
  • the clutch is in the rest position, the mobile 5 not being driven, and the elastic mobile 10 can rotate freely on its axis A.
  • bridge P undergoes a translation, comes into contact with the mobile 10, and press it against mobile 5 by moving the axis of rotation A by a deformation of the area 3. The mobile 10 is then in the clutch position.
  • the mobile 20 with its hub 2, the part elastic 3, and its transmission zone 4, is present in the form of a star achieving the function of a jumper.
  • the elastic part 3 of star 20 usually performs the function produced by a leaf spring.
  • a profile 21 of long necklace is part of a P bridge or a drowning fixed.
  • the star 20 thus advances a notch, or a not, by a deformation of the elastic zone 3 as shown in figure 7, and the star comes back in place after passing a tip relative to the profile 21.
  • the mobile 1, 10, or 20 can be used as anti-shock lateral for all applications watchmaking.
  • the mobile 30 comprises a hub 2, an elastic zone 3 formed by a succession of concentric lamellae 31 integral with hub 2 and the area of transmission 3.
  • the mode of Figures 8 and 9 is not only intended for the watchmaking field, but can be adapted to other applications such as suspensions of vehicles for example. Indeed, this adapted system vertically and directly on the wheels, can absorb shocks of all kinds and all directions.
