Definitions
- the field of the present invention relates to that of watches, in particular that of coaxial tubes. More precisely, the field of the present invention relates to that of guns for indicators.
- indicator coaxial tubes In the field of watchmaking, indicator coaxial tubes, more commonly known as guns, are tubes assembled coaxially. However, the lubrication of these tubes is made difficult and it is not easy to check whether the lubricating oil is in the desired location after assembly of the parts concerned.
- the lubricant is deposited on the coils of the tubes before assembly, then the latter are assembled axially on each other. During this assembly, the deposited oil can be pushed with one of the tubes, which moves the lubricant on one of the faces of the tube, and, in some cases, causes a sticking in the mechanism and often between 2 wheels. , or with one of the tubes. Summary of the invention
- the present invention relates to a clockwork mechanism comprising at least two coaxial tubes, preferably at least two guns; said at least two coaxial tubes, preferably said at least two guns both comprising a lateral opening so as to be able to be aligned. Thanks to this arrangement, it is possible to lubricate said at least two coaxial tubes, preferably said at least two guns in a single operation and this independently of the number of coaxial tubes. Furthermore, the lubrication of said at least two coaxial tubes, preferably said at least two guns, is guaranteed.
- the clockwork mechanism comprising an outer tube, preferably an outer barrel configured to receive said at least two coaxial tubes, preferably said at least two barrels. Thanks to this arrangement, said outer tube, preferably outer barrel, confines the lubricant in its enclosure and prevents any projections of lubricants at high rotational speed since said outer tube, preferably outer barrel, may not include side openings.
- said outer tube preferably outer barrel, comprises a lateral opening.
- the present invention also relates to a lubrication method for coaxial tubes of a timepiece mechanism according to the invention, said lubrication method comprising at least one step of:
- said lubrication method comprises at least one step of inserting said at least two coaxial tubes, preferably said at least two guns in said outer tube, preferably outer barrel after said at least one injection.
- FIG. 1 shows a sectional view of the watch mechanism 100 according to the invention
- - Figure 2 illustrates a top sectional view of the timepiece mechanism 100 according to the invention
- - Figure 3 shows a lubrication method 500 for coaxial tubes according to the invention.
- a clockwork mechanism 100 comprising at least two coaxial tubes 110, preferably at least two guns 110 and according to the embodiments, said clockwork mechanism 100 also comprises an outer tube 120. , preferably outer barrel 120 configured to receive said at least two coaxial tubes 110, preferably said at least two guns 110.
- said at least two coaxial tubes 110 preferably said at least two guns 110 are, firstly, assembled, according to a lubrication process 500 and more particularly during at least one assembly step 510 of said lubrication method 500.
- Said at least two tubes, preferably said at least two guns 110, shown in FIG. 1 are tubes mounted on a gear wheel, typically called guns as defined in the “Berner Illustrated Professional Dictionary of Watchmaking” such as the seconds wheel, the minute wheel and / or the hour wheel.
- Said at least two coaxial tubes 110, preferably said at least two guns 110 are assembled coaxially and the side openings 111 are aligned 520, according to at least one alignment step 520 of said lubrication method 500.
- At least one step of injecting 530 into said side openings 111 of a lubricant there follows at least one step of injecting 530 into said side openings 111 of a lubricant.
- said clockwork mechanism 100 is lubricated and said at least two coaxial tubes 110, preferably said at least two guns 110 are inserted into said outer tube 120, preferably outer barrel 120 during at least one insertion step 540 so that said outer tube 120, preferably outer barrel 120 confines the lubricant in its enclosure and prevents any projections of lubricants at high rotational speed, since in this embodiment , said outer tube 120, preferably outer barrel 120, may not include side openings 111.
- said outer tube 120 may also include a side opening 111, so as to lubricate the watch mechanism 100 even after assembly.
