The invention also relates to a portable watch 1000 with at least one energy storage device 20th which is intended with such a mechanism 100 to work together.

In the first variant, which is in 5 until 10 is shown, the assembly of the circumferential flywheel is consequently divided 1 into several different parts, which make it possible to separate the manufacture of its components. Thus, the first guide means, the second guide means and the balls form 90 in a special, non-limiting application, a ball bearing with possibly a cage together 65 or a basket that is from the toothed ring 2 , from the heavy sector, which is the inertial mass 4th forms, and from the flange 7th is separated, which advantageously forms a decoratable ring or a decoratable disc or a decorative cap. Each of the components of the flywheel is simplified to facilitate its manufacture and assembly. In particular, this arrangement makes it possible to avoid the tapping of hard materials such as ceramic, carbide or the like, or of soft and valuable materials such as gold, or to avoid unnecessary punching or milling processes, whereby the geometry of each component is strictly based on its own function and on the constraints of the Assembly with the other components is limited, the constraints being reduced to a minimum by the design of the flywheel according to the invention. Each component has a very simple geometry and is inexpensive to machine; the toothed ring 2 can be made directly by stamping, the inertial mass 4th comprises only smooth surfaces and generally neither a bore nor an internal thread, the bearing ring 6th can in turn be made of steel after conventional processing without any special effort.

The ball bearing comprises a first integral part, which is one of the two grooves 61 , 62 for rolling the balls 90 has, and a second part, which is formed from two components arranged one above the other, which are always expedient here with 361 , 362 are numbered whether they are upright or running, and which are common to the other of the grooves 62 , 61 for rolling the balls 90 define.

To simply ensure the relative geometric alignment of the components, at least one pin is required 21 or, in particular, are several pens 21 between certain components, for example between the inertial mass 4th and the bearing ring 6th , as in 10 to see this first variant, or between the inertial mass 4th and the toothed ring 2 , as in 19th to see for the third variant, which will be explained in more detail later, or the like attached. Thus, the ball bearing in particular is spared additional assembly. The inertial mass 4th is here between a collar 63 on the outer part of the bearing ring 6th is formed on the one hand and on the other hand either by the flange 7th or the toothed ring 2 who is at a lowering 43 the inertial mass 4th and these simple configurations are in no way limiting.

In this first variant, the moving part is located outside the ball bearing, based on the axis of mass D. The assembly of the flywheel 1 , including this ball bearing, is on the structure of the portable watch or the movement that it comprises, by means of screws from the inside in receptacles 31 of a fixed part 30th attached, which includes the ball bearing, three in number, which in the non-limiting variant shown are distributed over 120 °. These screws are accessible from the bottom of the portable watch, which makes the flywheel 1 is independent of the rest of the movement, like a conventional oscillating weight.

The second variant, which is in 11 until 14th is shown, the movable part is still outside of the ball bearing; the moving bearing ring 6th comprises a first conical contact surface 68 that are half of an inner or outer raceway 61 for circulating balls 90 or roles defined, and the toothed ring 2 forms a wreath that has a second conical contact surface 28 includes, in a working position in which the second conical contact surface 28 the first conical contact surface 68 opposite, the other half of the inner or outer running groove 61 Are defined. This cut-off ring is thus integrated into the ball bearing, which optimizes the height of the assembly. This also makes it possible to obtain a more advantageous lift capacity as the inertial mass 4th can be more voluminous. The flange 7th is screwed on from below.

In the in 14th The embodiment shown is the inertial mass 4th in the bearing ring 6th brought in. Complementary shapes, which are incorporated into each part in the manner of the dovetail assembly technique or the like, ensure the radial hold, not limited here by means of a dovetail assembly 604 shown.

The flange 7th has three tenons here 71 made of a material that accepts blind internal threads to pass through the screws 9 to enable its alignment and assembly. As in 13th can be seen is the screw 9 advantageously a bearing screw whose chin of the head 91 on one shoulder of the inertial mass 4th and / or on another shoulder of the bearing ring 6th arrives at the facility; a spring ring or a sealing ring can of course be placed in the stack of the components of the flywheel 1 can be inserted to compensate for their play and to ensure a good grip.

In the third variant, the moving part is located inside the ball bearing. The fixed part is on the outside, with the attachment under the flywheel 1 takes place on the dial side. This option allows the center of the caliber to be exposed, leaving more space for the remaining parts.

As with the first variant 1 the ball bearing has no pre-assembled components. The alignment pins 21 are in the inertial mass 4th brought in. Because this between a collar 63 of the bearing ring 6th on the one hand through the interaction of a contact surface 406 the inertial mass with a complementary contact surface 606 of the bearing ring 6th and the toothed ring 2 on the other hand through the interaction of a contact surface 204 of the ring 2 and a complementary contact surface 402 the inertial mass 4th is held in place is the toothed ring 2 through the screw 9 clamped, their countersunk head 91 on the flange 7th and those with an internal thread 605 of the bearing ring 6th cooperates. A lower surface 206 of the toothed ring 2 lies on an upper surface 602 of the bearing ring 6th at.

The fourth variant is derived from the third variant and comprises its movable part inside the ball bearing. The mass is fastened on the outside, on the bottom side. This is attached to the movement with three screws. Lugs on the periphery of the mass enable coupling.

In this fourth variant is the toothed ring 2 also separated from the ball bearing for ease of manufacture and assembly. The inertial mass 4th consists of two parts 41 and 42 to make it easier to manufacture. An inner or outer undercut groove 6040 is on the bearing ring 6th and on the inertial mass 4th designed to ensure the radial support of the latter.

A fifth variant is in the 25th until 31 shown. This fifth variant is without a flange 7th and only includes the other components of the flywheel 1 . The bearing ring 6th forms the outer part of a ball bearing with balls 90 . The toothed ring 2 is on the bearing ring 6th by screws 9 attached. The bearing ring 6th essentially comprises flat wings 64 that are designed to fit into recesses 46 fit that is the inertial mass 4th includes, and ensure their axial hold along the direction of the mass axis D. Some of the screws 9 be in ledges 609 who have favourited the bearing ring 6th includes on its circumference, and others either directly in internal threads of the inertial mass 4th or via the inertial mass 4th and cooperating with internal threads of the wings 64 screwed in as shown. The bearing ring 6th In the most cost-effective variant shown, it comprises a single outer groove for guiding the balls 90 . The inner part of the ball bearing comprises a first part 361 and a second part 362 , which are stacked on top of each other, each with a conical contact surface, each half of an inner groove for guiding the balls 90 forms.

In one non-limiting embodiment, and as in 28 seen is the second upper part 362 on the first lower part 361 through a flange 710 pressed that a solid part 30th forms that for attachment to a structure of the portable watch by bearing screws 900 is provided that in flange holes 709 inserted and in internal threads 906 are screwed, in particular with the help of positioning pins. The first part advantageously comprises 361 opposite its conical area for guiding balls a second small conical adjustment area, essentially at the same angle as the previous one, which cooperates with a complementary small conical adjustment area which the second part 362 includes, and one of these two conical adjustment areas is limited by a cylindrical stop contact surface in order to perfectly ensure the geometry of the inner groove for the ball guide in the assembled position.

In this fifth variant, the moving part of the flywheel is located outside the ball bearing and in particular outside the diameter of the housing fit, which requires assembly after the movement has been inserted into the middle part and a certain amount of play in the latter. The inertial mass 4th is on the ball bearing through the interaction of their recesses 46 with the wings 64 of the bearing ring 6th attached, which allows an axial and radial hold.

The attachment of the flywheel assembly 1 takes place through three flanges that are secured by bearing bolts 900 be screwed in the manner of classic casing-in in watchmaking. This process is carried out after the movement has been inserted into the central part, before the base is attached. In particular, two positioning pins are used in this fifth variant.

A special version of the fifth variant, shown in 27 and 28 , comprises an integral internal assembly of the ball bearing, an assembly of the heavy part, i.e. the inertial mass 4th , and this time on a pin rather than a dovetail, which requires the inertial mass to be drilled, but is less expensive than turning the dovetail profile. The connection with the plate is similar to that in 25th until 31 shown, but is now made more visible to the user.

28 shows the support surface 903 the bearing screw 900 in contact with the flange 710 with its underside on an upper contact surface 904 of the second part 362 of the fixed bearing ring 36 one of the lower shoulder 901 with an upper shoulder 902 the plate cooperates adjacent. 30th shows the system between two complementary surfaces 1902 the inertial mass 4th and 1901 of the movable bearing ring 6th .

• - die sechste Variante umfasst eine Positionierung mittels einer Platte und einen direkten Halt mittels einer Schraube; die Führung der Trägheitsmasse erfolgt durch eine Bohrung;
• - die siebte Variante umfasst eine Positionierung durch die Schraubenspur und das Halten durch die Schraube.

A sixth variant and a seventh variant are similar to this fifth variant, which is the assembly and mounting part of the inertial mass 4th concerns, they differ in the connection with the plate, the detail of their assembly is described above:

• the sixth variant comprises positioning by means of a plate and direct support by means of a screw; the inertia mass is guided through a hole;
• the seventh variant comprises positioning by the screw track and holding by the screw.

The invention has numerous advantages. In all cases, the lifting capacity is improved by the large diameter of the circumferential flywheel thus formed and the space requirement is improved in relation to the known devices by a substantial gain in overall thickness. Manufacturing is simplified, their cost is reduced, and assembly is easy. The aesthetic appearance of the flange is not affected by the technical restrictions.

The first variant differs in particular in its simple production thanks to its independent components, in its simple assembly, with the flywheel according to the invention being able to be assembled without special tools. The flange is particularly suitable for a versatile decoration.

The second variant differs in particular in its high lift capacity. The overall height can be greatly reduced.

The third variant is characterized by the fact that the aesthetic appearance of the volume contained inside the oscillating weight is not impaired by the technical constraints, and also by the fact that the fastenings on the clockwork protrude into the volume of the mass.

The fourth variant is also characterized by the fact that the aesthetic appearance of the volume that is contained inside the flywheel is not impaired by the technical constraints, and also by the fact that the lift capacity can be optimal.

The fifth variant enables the maximum possible optimization of the lifting capacity of the mass due to its outer movable part. The pivoting part outside the diameter of the case fit allows maximum gain of the available space in the center of the movement for the arrangement of all remaining components. The fastening of the fixed bearing ring with flanges facilitates assembly after the movement has been installed.

The sixth and the seventh variant guarantee good positioning and good fastening of the movable assembly to the plate.

For the variants with a flange 7th this can be made of noble metal due to the small height with which it can be formed, since the rigidity of the flywheel is due to the movable bearing ring 6th and through the toothed ring 2 is essentially guaranteed.
