Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, an anti-shock bearing comprising a bearing and a counter-pivot independent of one another.
  • the documents CH 255756 and CH 278334 propose anti-shock bearings in which the pierced stone, which acts as a cushion, is suspended floating in its housing by means of an elastic element.
  • This elastic element is held in position by the support of the kitten who carries the counter-pivot.
  • the counter-pivot is subjected to the effect of a return spring which maintains it and which ensures the axial positioning of the elastic element.
  • the positioning of the elastic element, and therefore of the pad, is consequently dependent on the kitten.
  • the elastic member In the case of a large axial or diagonal shock that would raise the counter-pivot and the kitten, the elastic member is no longer held in position by the return spring and the kitten, nor with respect to the housing, nor by report to the counter-pivot. It may therefore happen that the elastic element moves in an undesired manner, either relative to the housing, or relative to the counter-pivot. Therefore, the proper positioning of the breakthrough stone is not guaranteed at all times.
  • the documents CH 333250 , CH 243388 , CH 333591 and CH 296070 disclose bearings in which at least the pierced 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 because of unavoidable contact with oil, requiring periodic replacement. Moreover, these materials require a simple one-piece ring shape, which is very limited in terms of the possibilities for the optimization of the mechanical properties of the elastic member.
  • An elastic member of modern form, having an outer part, a central part, and 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. mechanics according to all degrees of freedom.
  • the document CH 245429 reveals a bearing comprising a spring element that supports the stone pierced in a central ring.
  • the spring element comprises bosses located at the end of four resilient 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 pierced stone is very sensitive to the tolerances of the four arms, and its mounting is difficult because it requires that the arms are clipped almost simultaneously in the groove.
  • this groove serves to position the spring element axially.
  • the document CH 313812 discloses a bearing in which a kitten carrying both stones is supported by means of an elastic ring comprising bulges extending outwardly and inwardly.
  • This elastic ring has a 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 elastic element. kitten comes out during an axial shock. Indeed, either the kitten will slide against the inner bulges, or the outer bulges will slide against the housing wall, during an axial impact, or both. This sliding will cause wear of the bulges and / or the kitten and / or housing, and thus the positioning of the pierced stone is not assured in the long term.
  • the document CH 292136 discloses yet another embodiment of a bearing, wherein the resilient member is constituted by a wire spring.
  • This wire spring is held and positioned axially in the housing being wedged between a shoulder and a ring driven into the housing above the wire spring.
  • This bearing is complex and difficult to disassemble for its maintenance with said ring driven.
  • the document FR 2020047 describes a bearing integrated with a racket, and is mounted on the cock through the latter. This bearing is complex and seems very difficult, if not impossible, to implement while maintaining an acceptable tolerance of 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 a kitten in which an elastic member carrying the pierced stone, a ring-shaped spacer and a counterpane stone are stacked in a housing and are held there by the efforts of a spring ring applied axially on the upper face of the counterpoise stone. These elements are simply placed on each other in the housing with play, which does not ensure their good positioning at any time.
  • the object of the invention is to provide anti-shock bearings in which the aforementioned defects are at least partially overcome.
  • the invention relates to a shockproof 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 spindle of an axis, such as an axis of a mobile, for example a balance shaft .
  • an elastic member comprising an outer portion, adapted to position the elastic member in the housing and having for example substantially the shape of a ring, a central portion comprising a pad located opposite said opening, and at least one elastic element connecting said outer portion to said central portion.
  • the pad comprises, as generally known, a hole for receiving the extension of the axis.
  • the pad may be formed by a separate piece attached to the central portion, such as a pierced stone of synthetic gemstone, a ring of metal material or silicon-based material (such as monocrystalline silicon, its oxide, its nitride, its carbide, also mono-or polycrystalline), or can be come from matter 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 tending to push the pivot against the bottom of the housing, and thus to maintain it in its position. rest.
  • the counter-pivot may be a counter-pivot stone of synthetic precious stone, an element made of metallic material or silicon-based material (such as mono- or polycrystalline silicon, its oxide, its nitride, its carbide, also mono- or polycrystalline).
  • the outer portion of the elastic member is held in the housing by friction generated by elastic forces exerted between said outer portion and the housing wall. These friction can be the result of a driving under 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 portion of the elastic member in the rest position of the bearing.
  • the elastic member self-positions in the housing, and regardless of the force of the return spring. In case of significant impact, it limits the risk that the elastic member can move or tilt relative to the housing, and therefore, the positioning of the pad relative to the housing is improved. Furthermore, the first bearing surface ensures good axial positioning of the pivot against the elastic member and thus relative to the pad.
  • a radial clearance exists between the kitten, if present, and the wall of the housing.
  • a radial clearance exists between the pivot and the kitten, 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 portion 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 radial width sufficient for said at least one elastic element remains free from the kitten.
  • This arrangement provides a greater axial distance of contact between the central hole 11a of the pad 11 and the pivot axis.
  • the second bearing surface serves as a stop to avoid any risk that the pad and the counter-pivot can come into contact during a shock of great importance.
  • the kitten is not present, the counter-pivot or the elastic member being shaped so that it also takes the functionality of the kitten.
  • the counter-pivot itself comprises a first bearing surface arranged to be in contact with said outer portion of the resilient member in the rest position of the bearing.
  • the counter-pivot may also comprise 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 situated between said first bearing surface bearing surface and said second bearing surface.
  • this arrangement provides a greater axial distance of contact 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 pad and the counter-pivot can come into contact during a violent impact.
  • a radial clearance may exist between the pivot and the housing wall, which simplifies the assembly and disassembly of the bearing.
  • the outer portion of the elastic member may comprise at least one abutment member projecting in a direction opposite to said bottom, that is to say projecting from the upper surface of the part. exterior.
  • This stop element is adapted to position axially against the pivot when the bearing is in the rest position. This positioning can be made, if necessary, either by directly positioning a counter-pivot without a kitten, or by positioning a kitten which carries a counter-pivot.
  • This positioning can be made, if necessary, either by directly positioning a counter-pivot without a kitten, or by positioning a kitten which carries a counter-pivot.
  • 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 tigeron of an axis, such as a balance shaft.
  • an elastic member Arranged in the housing is an elastic member having an outer portion adapted to position the resilient member, a central portion comprising a pad located opposite said opening, and at least one elastic member connecting said outer portion to said central portion.
  • the pad comprises, as generally known, a hole for receiving the extension of the axis.
  • the pad may be formed by a separate piece attached to the central portion, such as a pierced stone of synthetic gemstone, a ring of metal material or silicon-based material (such as monocrystalline silicon, its oxide, its nitride, its carbide, also mono-or polycrystalline), or can be come from matter with the central part.
  • a counter-pivot is located in the housing in front of 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 thus to maintain it in its rest position.
  • the counter-pivot may be a counter-pivot stone of synthetic precious stone, an element made of metallic material or 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 which can take for example substantially the shape of a ring, is fixed to the kitten.
  • This fixing can be obtained by welding, brazing, gluing, pinning.
  • the outer portion of the elastic member may be held in the kitten by friction generated by elastic forces exerted between said outer portion and an inner wall of the kitten by hunting under elastic regime, additional elastic tongues or fingers or similar. Therefore, the elastic member is well positioned relative to the kitten and therefore to the counter-pivot at any time, even in case of shock very important.
  • the kitten comprises an inner shoulder in which said outer portion takes place.
  • the axial positioning of the elastic element relative to the kitten can thus be easily guaranteed.
  • said shoulder has a height less than the thickness of said outer portion, such that, in the rest position of the bearing, said outer portion is in contact with the bottom of the housing, said kitten remaining out of contact with said bottom of the housing.
  • the kitten and the counter-pivot came from material and therefore be monoblock, for example in the case of manufacturing by micro-machining.
  • the bottom of the housing comprises a shoulder arranged to be in contact with the outer portion of the elastic member. Consequently, the elastic element and the central part of the elastic member are not in contact with the bottom of the housing, and applies for any embodiment stated above.
  • FIGS. 1 to 4 illustrate an anti-shock bearing according to the invention in the rest position.
  • the geometric axis of the bearing is defined as being perpendicular to the intersection of axes AA and BB indicated on the figure 2 .
  • the "radial” and “axial” directions therefore refer to the axis of the landing.
  • This bearing comprises, as is generally the case, a housing 3 in which are housed the components of the bearing.
  • this housing 3 is formed in a cup intended to be secured to a frame member of a watch movement, such as a platinum or a bridge.
  • the housing 3 can be formed directly in the body of a plate or a bridge, by machining it directly.
  • the housing is delimited by a bottom 3a, extending in a plane perpendicular to the axis of the bearing 1, and by a substantially cylindrical wall 3b, which extends perpendicular to the plane of the bottom 3a and parallel to the bearing axis 1.

  • the outer part 9a can be positioned either by driving with elastic deformation, or by additional elastic elements such as tongues or fingers extending outwardly from the outer part 9a, and bearing against the cylindrical wall of the housing 3.
  • the outer portion 9a bears resiliently against the housing wall, which generates mutually complementary forces on the wall and on the outer portion 9a in a substantially radial direction. These forces generate a friction that is sufficient to secure these components with each other during operation of the bearing.

  • the level proposed in these figures therefore has fewer components than the embodiment of the Figures 1 to 4 and is more economical to implement. Nevertheless, the same principle also applies to an embodiment having a kitten, and this, particularly in the case where the kitten is a simple ring, circular or split, driven flush around the counter-pivot 13.
  • the counter pivot 13 and the kitten 15 of the embodiment of the Figures 1 to 4 can come from a room for the case where no clearance between these components is deemed necessary, the shape of the kitten 15, and particularly that of the first and second bearing surfaces 15a, 15b and that of the groove 15c being taken over in the form of the counter pivot 13. This variant is not illustrated.

  • Level 1 of Figures 9-11 differs from those Figures 1-8 in that the elastic member 9 is no longer held directly in the housing 3, but is fixed in the kitten 15. This attachment can be achieved by means of the friction generated by elastic forces exerted between said outer portion 9a and the wall of the kitten (hunting, elastic elements, as mentioned above), or by gluing, welding, brazing, pinning or the like.

  • the inner shoulder 15a has a height less than the thickness of the outer portion 9a, so that the kitten 15 does not come into contact with the bottom 3a of the housing 3. Therefore, the outer portion 9a remains in contact with the the shoulder 7 of the bottom 3a of the housing 3.
  • said height is greater than said thickness, or that these two are equal.
  • the periphery 17b of the return spring 17 is not in contact with the kitten or against the pivot 13 in its rest position. Nevertheless, said periphery 17b can serve as an axial stop to limit the axial displacement of the kitten 15 during a strong impact.
  • the counter-pivot 13 is driven, welded, brazed or glued into the upper part of the kitten 15, which is tubular in shape, but it is also possible for the counter-pivot 13 to take a position against a suitable shoulder, as is the case in Figures 1 to 6 , with or without play between these two elements.
