摘要:
The invention relates to a composite balance (45, 45′) formed in a layer of silicon-based material (21) and including a hub (39, 39′) connected to a felloe (37, 37′) by at least one arm (40, 41, 42, 43). According to the invention, the felloe (37, 37′) includes at least one additional part approximately in the shape of a notched ring (23, 23′) of higher the than the silicon-based material, which increases the inertia of the balance. The invention also relates to a method 1 of manufacturing this type of balance. The invention concerns the field of timepiece movements.

An oscillating mechanism for a timepiece movement, including a first rigid element and a second rigid element, each one fixed on a different element of the movement and at least one of which is mobile relative to the other and pivots about an axis. The mechanism is monobloc and flexible with a variable geometry, and includes a first elastic restoring mechanism producing an elastic connection between the first rigid element and an intermediate rigid element, and a second elastic restoring mechanism producing an elastic connection between the intermediate element and the second rigid element, which all are coplanar according to one plane and configured to be deformed according to the plane.

The invention relates to a single piece coaxial escape wheel set (100, 100′) including a first toothing (108, 108′) formed at the periphery of a plate (103, 103′) and a second toothing (113, 113′). According to the invention, the second toothing (113, 113′) is formed in a single piece with the plate (103, 103′) of the first toothing (108, 108′) so as to reduce any problems of alignment of one in relation to the other and to decrease the overall mass of the wheel set (100, 100′).The invention concerns the field of timepieces.

The invention relates to a timepiece component (1) that has an aperture (7) for receiving a support element (3) and includes a clamping system (13) for exerting radial force, enabling said timepiece component to be secured to said support element. According to the invention, the clamping system (13) includes a radial clamping device (15) that has a crown (6) for exerting said radial force and a concentric, blind recess (8) spaced apart from said aperture, to allow a travel for the crown. Moreover, the clamping system (13) further includes a device allowing a travel (17) that has a second, concentric, blind recess (10), spaced apart from said first blind recess (8), and located on the opposite surface to said first recess, to allow said crown a greater degree of freedom relative to said support element.The invention concerns the field of timepieces.
摘要:
A balance set for a timepiece, with inertia adjustment for adjusting inertia and/or balancing and/or oscillation frequency of the balance, with a balance including an insert inserted into a recess of a felloe connected to a hub by a joining surface. The balance includes on the felloe thereof an elastic holding mechanism including two antagonistic elastic lips which, when stressed, allow insertion of the insert into the recess and which, when released, prevent removal of the insert from the recess. A sprung balance or a timepiece can incorporate such a balance.

The invention relates to a gear train (51, 51′) including an arbour (53, 53′) a first end of which is fitted with an integral collar (52, 52′), a first wheel set (55, 55′) made of micro-machinable material being fitted onto the second end of the arbour (53, 53′). According to the invention, the gear train (51, 51′) includes a second wheel set (57, 57′) made of micro-machinable material, which is independent of the movements of said first wheel set and which includes an aperture (58, 58′) whose wall is mounted opposite said arbour so that the second wheel set (57, 57′) is freely mounted on said first end of the arbour (53, 53′).
