摘要:
The timepiece escapement includes first (3) and second (4) impulse pallet stones secured to the balance (2) directly cooperating with the teeth of the escape wheel set (1) and a brake lever (5) periodically driven by the balance, the brake lever being provided with first (6) and second (7) locking pallet stones arranged for cooperating with the teeth of the escape wheel set (1).
摘要:
The mobile element includes a central rigid zone (2) provided with arms (6) extending radially from the central zone (2) towards a peripheral zone including teeth (8). The arms (6) are flexible to allow a small tangential and/or radial movement of the teeth (8) in order to absorb shocks. The invention is characterized in that the arms (6) are curved and bend gradually towards an orientation tangential to the rotation of the mobile element, in that the thickness of the arms gradually decreases, and finally, in that the ends of the arms form the teeth.
摘要:
The process comprises the following steps:a) a first element (3) or a plurality of said first elements (3) is/are machined in a first silicon wafer (1) keeping said elements (3) joined together via material bridges (5); b) step a) is repeated with a second silicon wafer (2) in order to machine a second element (4), differing in shape from that of the first element (3), or a plurality of said second elements (4); c) the first and second elements (3, 4) or the first and second wafers (1, 2) are applied, face to face, with the aid of positioning means (6, 7); d) the assembly formed in step c) undergoes oxidation; and e) the parts (10) are separated form the wafers (1, 2). Micromechanical timepiece parts obtained according to the process.
摘要:
The resonator (1) for a timepiece results from coupling a first, low frequency resonator (2) with a second, higher frequency resonator (3). The first resonator (2) has a first balance (4) associated with a first balance spring (5). The second resonator (3) has a second balance (6) associated with a second balance spring (7). A third balance spring is arranged between the first (4) and second (6) balances to couple said first (2) and second (3) resonators.
摘要:
The escapement includes two distinct escape wheel sets (1, 2), a roller (3) including a first impulse pallet stone (5) cooperating with the first wheel set (1) and a third impulse pallet stone (12) cooperating with the second wheel set (2). An anchor piece (6) articulated on a pivot (7) cooperates with an impulse pin (4) via a fork (8) fitted to the anchor piece. This anchor piece carries second (9) and fourth (13) impulse pallet stones respectively cooperating with the first (1) and second (2) wheel sets. The same anchor piece carries first (10) and second (11) locking pallet stones cooperating with the second wheel set (2).
摘要:
The invention concerns an escapement (1) for a timepiece comprising an anchor (2) articulated on a stem (3) and co-operating with an escapement mobile (4) articulated on an axis (5), said mobile comprising a plurality of teeth (8; 15, 16) uniformly spaced around said mobile, said anchor including an entry pallet (6) and an exit pallet (7) arranged to receive alternately an impulse from one of the teeth borne by the mobile and for acting as rest plane for said tooth. The invention is characterized in that the escapement mobile (4) comprises first and second integral and coaxial wheels (13, 14) including each the same number of teeth (15, 16), in that the entry and exit pallets (6, 7) co-operate respectively with the first and second wheels (13, 14) and in that the peripheral radius (R1) of the first wheel (13) is greater than the peripheral radius (R2) of the second wheel (14).
摘要:
The lever escapement includes at least one escape wheel (2). The pallet assembly (5) is fitted with locking pallet stones (6, 7) and a first impulse pallet stone (8) cooperating with the teeth of the wheel (2). The pallet assembly (5) drives an auxiliary wheel set (9) carrying a second impulse pallet stone (10) cooperating with the teeth of the wheel (2).

摘要:
The housing (6) of the bearing block (1), locks the peripheral ring (11) of a spring (10) with axial and radial deformation further comprising a substantially annular rigid central support (13) which cooperates with a cap (23), fitted by means of lugs (25) to the outside of the central support (13), to hold the pierced stone (4) and the endstone (5). The resilient part (12) of the spring (10) is for example formed of bent arms.
