Definitions

  • the present invention relates to the field of watchmaking. It relates more particularly to a shock-proof bearing comprising a bearing and a counter-pivot independent from one another.
  • the documents CH 255756 and CH 278334 offer shock-resistant bearings in which the pierced stone, which acts as a cushion, is suspended in a floating manner in its housing by means of an elastic element.
  • This elastic element is held in position by the support of the kitten which carries the counter-pivot.
  • the counter-pivot is subjected to the effect of a return spring which maintains it and which guarantees the axial positioning of the elastic element.
  • the documents CH 333250 , CH 243388 , CH 333591 and CH 296070 disclose bearings in which at least the drilled stone is supported in the housing by means of a one-piece rubber or elastomer ring.
  • the choice of material for the elastic member of these documents is clearly not satisfactory for long-term use of the bearing. Rubber and elastomers typically degrade over time and due to inevitable contact with oil, requiring their periodic replacement. In addition, these materials require a simple one-piece ring shape, which is very limited in terms of possibilities. for the optimization of the mechanical properties of the elastic member.
  • An elastic member of modern shape, having an outer part, a central part, as well as at least one elastic element connecting these two, has significantly more freedom compared to a simple ring in terms of its design, and therefore its properties. mechanical according to all degrees of freedom.
  • the document CH 245429 unveils a bearing comprising a spring element which supports the stone pierced in a central ring.
  • the spring element has bosses located at the end of four elastic arms, the bosses taking place in a groove so that they exert a force on the bottom of the latter.
  • the radial positioning of the drilled stone is very sensitive to the tolerances of the four arms, and its assembly is difficult because it requires the arms to be clipped almost simultaneously into the groove. Furthermore, this groove serves to position the spring element axially.
  • the document CH 313812 discloses a bearing in which a kitten carrying the two stones is supported by means of an elastic ring comprising bulges extending outwardly and inwardly.
  • This elastic ring has very low flexibility perpendicular to its plane, and in view of the fact that the single kitten also carries the counter-pivot, an axial displacement between the housing and the elastic element and / or between the elastic element and the kitten arises during an axial impact.
  • either the kitten will slide against the interior bulges, or the exterior bulges will slide against the wall of the housing, during an axial impact, or both. This slippage will lead to wear of the bulges and / or of the bezel and / or of the housing, and therefore the positioning of the pierced stone is not guaranteed in the long term.
  • the document CH 292136 describes yet another embodiment of a bearing, in which the elastic member consists of a wire spring.
  • This wire spring is maintained and positioned axially in the housing by being wedged between a shoulder and a ring driven into the housing above the wire spring.
  • This bearing is complex and difficult to dismantle for maintenance thanks to said driven ring.
  • the document US 2,700,273 describes a bearing in which a ring of circular section is located at the bottom of the housing and against which a bevelled wall of the kitten rests in order to position the kitten radially, but not axially.
  • the bevelled wall slides on the ring in order to make the kitten move against a spring.
  • the kitten is therefore not integral with the ring, and is free to move relative to the latter, which does not guarantee a good positioning of the pierced stone.
  • the document FR 2020047 describes a bearing integrated into a racket, and is mounted on the rooster through the latter. This level is complex and seems very difficult, if not impossible, to implement while maintaining an acceptable tolerance for the position of the pierced stone. The correct positioning of the latter is therefore difficult to ensure.
  • the document CH 262967 describes a bearing without chaton in which an elastic member carrying the drilled stone, a spacer in the form of a ring and a counterpivot stone are stacked in a housing and are held there by means of the forces of a spring ring applied axially on the upper face of the counterpivot stone. These elements are simply placed on top of each other in the housing with play, which does not ensure their correct positioning at all times.
  • the aim of the invention is to provide anti-shock bearings in which the aforementioned defects are at least partially overcome.
  • the invention relates to a shock-proof bearing for a timepiece according to a first independent claim.
  • This bearing comprises a hollow housing comprising a wall and a bottom, and an opening in said bottom of the housing, intended to receive a rod of an axis, such as an axis of a mobile, for example of a balance axis. .
  • an elastic member comprising an outer part, adapted to position the elastic member in the housing and having for example substantially the shape of a ring, a central part comprising a pad located in front of said opening, and at least one elastic element connecting said outer part to said central part.
  • the bearing comprises, as generally known, a hole intended to receive the extension of the axis.
  • the pad can be formed by a separate part fixed to the central part, such as a pierced stone in synthetic precious stone, a ring in metallic material or in silicon-based material (such as mono- or polycrystalline silicon, its oxide, its nitride, its carbide, also mono or polycrystalline), or can be integral with the central part.
  • a counter-pivot is located in the housing opposite the pad, and is subjected to a force exerted by a return spring arranged to push the counter-pivot towards the bottom of the housing, and therefore to maintain it in its position of rest.
  • the counter-pivot can be a counter-pivot stone made of synthetic precious stone, an element made of metallic material or of silicon-based material (such as mono- or polycrystalline silicon, its oxide, its nitride, its carbide, also mono-. or polycrystalline).
  • the outer part of the elastic member is held in the housing by friction generated by elastic forces exerted between said outer part and the wall of the housing. This friction may be the result of driving in under an elastic regime, or the result of deformations of additional elastic elements such as elastic tongues or fingers or the like.
  • either a kitten which supports said counter-pivot, or the counter-pivot itself in the case of a bearing without a kitten comprises a first bearing surface arranged to be in contact with said outer part of the elastic member in the rest position of the bearing.
  • the elastic member self-positions in the housing, and independently of the force of the return spring.
  • the risk of the resilient member being able to move or tilt relative to the housing is limited, and consequently the positioning of the pad with respect to the housing is improved.
  • the first bearing surface ensures correct axial positioning of the counter-pivot relative to the elastic member and therefore relative to the bearing.
  • a radial clearance exists between the kitten, if present, and the wall of the housing.
  • a radial play exists between the counter-pivot and the chaton, if present.
  • the side wall of the kitten adjacent to the counter-pivot may be cylindrical or conical, a conical wall particularly facilitating the mounting of the counter-pivot in the kitten.
  • the kitten if present, comprises a second bearing surface arranged to be in contact with said central part of the elastic member when the bearing is in the rest position.
  • This second bearing surface is separated from the first bearing surface by an annular groove located between said first bearing surface and said second bearing surface.
  • This groove preferably has a sufficient radial width for said at least one elastic element to remain free with respect to the kitten.
  • This arrangement ensures a greater axial contact distance between the central hole 11a of the bearing 11 and the pivot of the axis.
  • the second bearing surface serves as a stop to avoid any risk that the bearing and the counter-pivot may come into contact during a shock of very great importance.
  • the kitten is not present, the counter-pivot or the elastic member being shaped so that it also takes over the functions of the kitten.
  • the counter-pivot itself comprises a first bearing surface arranged to be in contact with said outer part of the elastic member in the rest position of the bearing.
  • the counter-pivot may also include a second bearing surface arranged to be in contact with said central part of the elastic member in the rest position of the bearing, separated from the first bearing surface by an annular groove located between said first bearing surface and said second bearing surface.
  • this arrangement ensures a greater axial contact distance between the central hole 11a of the pad 11 and the pivot of the axis, and the second bearing surface serves as a stop to avoid any risk that the bearing and the counter-pivot may come into contact during a violent impact.
  • a radial play may exist between the counter-pivot and the wall of the housing, which simplifies the assembly and disassembly of the bearing.
  • the outer part of the resilient member may comprise at least one stop member projecting in the direction opposite to said bottom, that is to say projecting from the upper surface of the part. exterior.
  • This stop element is suitable for axially positioning the counter-pivot when the bearing is in the rest position. This positioning can be carried out, if necessary, either by directly positioning a counter-pivot without a kitten, or by positioning a kitten which carries a counter-pivot.
  • another embodiment is proposed with or without a kitten which has the advantages of the invention.
  • the invention also relates to an anti-shock bearing for a timepiece, as defined in a second independent claim.
  • This bearing comprises a housing comprising a wall and a bottom, and an opening in said bottom, said opening being intended to receive a shank of an axis, such as a balance axis.

  • a counter-pivot is located in the housing opposite the pad, where it is supported by a kitten located in the housing.
  • the counter-pivot is subjected to a force exerted by a return spring arranged to push it in. direction of said housing bottom, and therefore to maintain it in its rest position.

  • the outer part of the elastic member which may for example take substantially the form of a ring, is fixed to the kitten.
  • This fixing can be obtained by welding, brazing, gluing, pinning.
  • the outer part of the elastic member can be held in the kitten by friction generated by elastic forces exerted between said outer part and an internal wall of the kitten by driving under elastic regime, additional elastic tongues or fingers or similar. Consequently, the elastic member is well positioned relative to the kitten and therefore to the counter-pivot at all times, even in the event of a very severe impact.
  • the kitten comprises an inner shoulder in which said outer part takes place.
  • the axial positioning of the elastic element relative to the kitten can therefore be easily guaranteed.
  • said shoulder has a height less than the thickness of said outer part, so that, in the rest position of the bearing, said outer part is in contact with the bottom of the housing, said kitten remaining out of contact with said bottom of the bearing. lodging.
  • chaton and the counter-pivot are integral and therefore be in one piece, for example in the case of manufacture by micromachining.

In fact, the elastic member 9 is maintained in the correct position by itself.
