- Such a barrel assembly is bulky in the thickness of the watch movement or in the direction of the axis of the barrel shaft. This is particularly disadvantageous for creating an extra-flat watch movement.
- the aim of the invention is to provide a watch assembly remedying the drawbacks mentioned above and improving the watch assemblies known from the prior art.
- the invention proposes a simple watch assembly, which can be dismantled and allows mounting of a barrel shaft on a movement blank while minimizing the bulk in the direction of the thickness of the watch movement. Summary of the invention
- the invention relates to a watch assembly of a shaft, in particular a barrel shaft, on a blank, in particular a bridge or a plate.
- the shaft comprises a first axis and a bearing extending at least in a direction radial to the first axis.
- the blank includes a groove oriented along a second axis.
- the shaft and the blank are configured and/or arranged so as to:
- a watch movement is defined by claim 7.
- a timepiece is defined by claim 12.
- a watchmaking device is defined by claim 16.
- Figure 1 is a view of one embodiment of a timepiece according to the invention, one embodiment of a watch movement according to the invention being shown in more detail in perspective section.
- Figure 2 is a perspective view of the embodiment of the watch movement according to the invention, the barrel ratchet, the barrel shaft and the barrel spring being removed.
- Figure 3 is a partial sectional view of the embodiment of the timepiece according to the invention, the section being made at the level of the barrel shaft.
- Figure 4 is a perspective view of an assembled barrel ratchet-shaft assembly.
- Figure 5 is a perspective view of the embodiment of the watch movement according to the invention.
- the timepiece 200 is for example a watch, in particular a wristwatch.
- the timepiece 200 comprises a watch movement 100, intended to be mounted in a case or a timepiece box in order to protect it of the external environment.
- the watch movement 100 can be a mechanical movement, in particular an automatic movement.
- the 100 watch movement includes:
- a frame 90 in particular a blank or a plate 91, and
- the watch movement 100 also includes a watch assembly 1 of a shaft 81 of the barrel on the frame 90, in particular the blank 91, in particular the plate 91.
- the assembly makes it possible to link the barrel to the frame, in particular to mechanically link the barrel shaft 81 and a wheel 84, in particular a ratchet, to the frame.
- the mechanical connection is preferably a pivot connection from the shaft 81 to the blank 91, in particular a pivot connection around an axis A80 constituting the axis of the shaft 81.
- the plate 91 also constitutes a back, or even a middle back.
- the back and the plate can be made in the same single piece.
- the case or timepiece box is advantageously closed by a glass 10.
- Barrel 80 includes:
- a driving spring (not shown) mechanically linking the toothed ring 85 to a bung 812 formed by an external surface of the shaft 81.
- the toothed wheel 83 is fixed on the shaft 81 using a screw 84. More precisely, the toothed wheel 83 and the shaft 81 preferably comprise complementary conformations which fit together. in the others by translation along axis A80 and held in nested configuration by screw 84.
- a mainspring housing is delimited by:
- the diameter of the toothed wheel 83 is greater than the diameter of the toothed ring 85 or toothed ring 85.
- the toothed ring 85 is guided in rotation on the frame 90, in particular on the blank 91 or on bridges attached to the blank 91, by rollers 70, in particular ruby rollers.
- rollers 70 in particular ruby rollers.
- three rollers 70 are preferably used.
- a single roller 70 is shown in the figures. The rollers are arranged to roll on a cylindrical peripheral surface 851 of the toothed ring.
- the rollers can be pivoted around axes 71 driven into a blank.
- the movement comprises pins 98 adjustable in position parallel to the first axis A80.
- the pins 98 are preferably arranged so as to define, by contact with the toothed wheel 83, a movement of the toothed wheel 83 along the first axis A80 and to maintain the toothed wheel 83 parallel to the blank 91 and to the ice 10, even in the presence of forces acting on the teeth of the toothed wheel 83.
- the shaft 81 comprises a bearing surface 82 extending at least in a radial direction to the first axis A80
- - the blank 91 comprises a groove 92 oriented along a second axis A90, the shaft and the blank being configured and/or arranged so as to:
- the barrel shaft has at one of its ends 813, a groove 814, one of the flanks 82 of which forms the surface 82.
- the groove can be constituted by the assembly of several components.
- the groove 92 made in the blank 91 is a T-section groove opening at only one of its ends. This groove is made along the second axis A90.
- a sidewall 96 of the groove is arranged to cooperate with the surface 82.
- the shaft having at least at its end 813 a geometry of revolution and/or the groove having at its non-opening end a geometry of revolution the shaft can rotate freely in the groove around the A80 axis.
- the groove opens at one of its ends allows the introduction of the shaft 81 into the groove by moving it in the direction of the second axis A90. Of course, this movement is only possible when the wheel 83 is removed from the end 81 1 of the shaft 81.
- the surface 82 and the side 96 each form a plane perpendicular to the first axis A80, both planes acting on one another to limit, along the axis A80, the translation of the shaft 81 relative to the blank 91.
- the surface 82 could be frustoconical and could cooperate with a frustoconical surface in the groove and/or with surfaces in inclined planes in the groove.
- the blank 91 may comprise a plug 93 driven into a hole 94 made in the main part of the blank 91 (i.e. in the rest of the blank 91), in particular a through hole 94.
- the plug 93 is glued in the hole 94, in particular so as to create a watertight connection.
- the blank 91 preferably comprises a plug 93 driven into a main part 91. This makes it possible to make the main part of the blank 91 and the groove 92 in different materials, the groove 92 being made in the plug 93.
- the hole 94 can be bordered by an extra thickness formed on the main part of the blank 91 (i.e. on the rest of the blank 91). This extra thickness is advantageously local and/or provided locally around the hole 94.
- the hole and the plug can be generally cylindrical in shape or polygonal in shape.
- the mainspring is placed in the housing by connecting it to the bung 812 and the toothed ring 85.
- the shaft and the spring can first be attached to each other, then the assembly thus formed can be mounted in the toothed ring previously mounted on the blank 91 or on frame 90.
- the invention also relates to such an assembly method and to the assembly obtained by implementing this method.
- the toothed wheel 83 or ratchet 83 is intended to mesh with a reference 89, like a reference of a watch winding kinematic chain.
- this reference is arranged to mesh with the toothed wheel 83 or the ratchet 83 in a place such that the actions applied by the reference 89 on the toothed wheel 83 or on the ratchet 83 prevent the movement of the shaft 81 in translation in the direction A90 the groove 92.
- the actions may have a tendency to push the shaft 81 in translation towards the bottom of the groove 92.
- the thickness of the timepiece is minimized.
- the thickness of the timepiece can be broken down (without taking into account functional games) in the sum of:
- the assembly has been described applied to the assembly of a barrel shaft on a blank, in particular a plate.
- the assembly can be used to mount any type of watch shaft on a blank, or even more widely on a watch component.
- the shaft 81 in particular the barrel shaft, is preferably mounted cantilevered, that is to say mechanically linked to the frame 90 or to the blank 91 via a bearing, or more generally via a guide, at only one of these ends. This makes it possible in particular to obtain a space-saving assembly in the longitudinal direction of the shaft or along the A80 axis.
- the shaft 81 in particular the barrel shaft, is preferably mounted on the blank 91 or on the frame 90 without passing through the latter in the longitudinal direction to the shaft or in the direction of the axis A80. This makes it possible in particular to ensure a seal between two spaces limited by faces of the blank 91 or of the frame 90 extending at least substantially perpendicular to the shaft or to the axis A80.
- the toothed ring 85 is preferably not guided in rotation on the shaft 81. This makes it possible to do without a mechanical element connecting the toothed ring to the shaft and therefore to obtain a space-saving assembly in the longitudinal direction of the shaft or along the A80 axis.
