Definitions
- the present invention relates to a motor unit for the watch industry, in particular a motor member with a moment of substantially constant force.
- the clock motor unit according to the invention can be either a motor of a watch movement arranged to drive a finishing gear, or a motor member of an additional mechanism such as a striking mechanism or a mechanism of chronograph.
- a barrel In watchmaking, a barrel has traditionally been used as the driving mechanism of a watchmaking mechanism.
- a barrel is an assembly of at least three elements: a barrel spring consisting of a spiral spring blade, a barrel drum serving as a housing for said spring, said drum being freely rotatable on a barrel shaft (pivoting shaft between bridge and platen), and a barrel cover for closing the barrel drum, said lid also being freely rotatable on the barrel shaft.
- the blade comes out in the shape of an inverted S. The unwinding of the blade, wound against the diameter of the bung of the barrel shaft and seeking to return to its original shape, produces the energy necessary for the operation of the clock mechanism.
- a disadvantage of such a motor member is that its performance is affected by the friction of the turns of the spiral spring against each other and against the inside of the barrel drum, during unwinding of the barrel. To reduce this friction, it is usual to lubricate the turns of the spring and deposit an anti-friction coating in the drum. Despite this, such a drive member suffers energy losses of about 15% due to friction.
- Such a motor unit is therefore expensive and difficult to manufacture.
- the object of the present invention is to provide an alternating drive member to the barrel comprising a spiral spring traditionally used which makes it possible to overcome, at least in part, the aforementioned drawbacks.
- the invention proposes for this purpose a clockwork motor unit comprising at least two monolithic units stacked and connected in series, each of these units comprising a hub and a serge connected by at least one elastic arm.
- the present invention also proposes a clock mechanism comprising such a clock motor unit.
- the motor member according to the invention has the advantage of significantly improving the efficiency (average energy loss between 0 and 3% only against 15% for a traditional spiral spring barrel). Indeed, the monolithic units that compose it do not undergo or very little friction.
- the motor member according to the invention also has the advantage of delivering a moment of force substantially constant, thus improving the isochronism of the watch movement with which it is associated, without require intermediate spring between the drive member and the exhaust.
- FIG. 1 is a perspective view of a part of a watch mechanism incorporating a clockwork motor member according to a particular embodiment of the invention
- FIG. 1 is a top view of the mechanism shown in Figure 1;
- FIG. 3 is a cross-section of the driving member of FIG.

- FIGS. 5a and 5b are views respectively from below and from above of a unit of the motor member equipped with a centering device;
- FIG. 6 is a schematic graphical representation of the moment of elastic return exercised in a unit of the motor unit
- FIG. 7 shows the coordinates of points defining a particular form of elastic arm for each unit of the motor member
- FIG. 8a is a graphical representation of the moment of elastic return exercised in a given unit of the motor unit comprising elastic arms having the shape as represented in FIG. 7;

- the first 1 10 of said units is associated with a toothing 160 for connection with the winding gear 5b.
- This toothing 160 which meshes with the winding gear 5b is typically carried by a winding wheel 170 coaxial and integral with the hub 120 of said first unit 1 10, as shown in Figures 1, 2, 3 and 4a.
- the toothing 160 may be integral with the serge 130 of the first unit 1 10.
- the last 310 of said units is associated with another toothing 360 which meshes with the work train 3 to deliver a moment of force.
- This other toothing 360 is typically integral with the serge 330 of the latter unit 310, as shown in Figures 1, 2, 3 and 4c.

- Intermediate units 210 placed between said first and last 310 units are not associated with a toothing, as shown in FIGS. 1, 3 and 4b.
- each of the units 1 10, 210, 310 according to the invention is unidirectional, that is to say it has, due to the shape of its elastic arms 140, 240, 340, a direction of rotation privileged its serge 130, 230, 330 relative to its hub 120, 220, 320, this sense being defined as that which, from the state of rest of the unit considered, the largest relative angular displacement of its serge 130, 230, 330 with respect to its hub 120, 220, 320.

- the preferred direction of rotation of the first 1 10 and the last 310 units and the choice of the input and output elements (serge or hub) depends on the position of the motor unit 1 in the watch mechanism and depends on the mechanism
- the preferred direction of rotation of the intermediate units 210 is tuned according to their number and in the direction of the first 1 10 and last 310 units.
- the hubs 120, 220, 320 of the units 1 10, 210, 310 of the motor unit 1 comprise bores 150, 250, 350, for example circular, these bores 150, 250, 350 being traversed by the axis 2 of the watch movement, said axis 2 is preferably fixedly mounted relative to the movement, for example in the movement plate.
