Definitions

  • the invention relates to the field of watchmaking. It relates to an escapement according to the preamble of the corresponding independent patent claims.
  • WO 01/59529 WO 00/04424 and US 6877893 describe an inhibition in which a Hemmanker and an outer attachment point of the spiral spring of a balance are both attached to a Hemm Kunststoff which rotates about the axis of the balance.
  • the escapement for a mechanical watch thus has a balance which oscillates in conjunction with a balance spring, and an anchor which cooperates with an escapement wheel.
  • the balance is driven by the balance spring.
  • the forces which stimulate the oscillation of the balance are transmitted to the balance by the balance spring.
  • the excitation is done exclusively by the balance spring.
  • the balance on the balance spring mechanically coupled to the anchor, in particular attached to the anchor.
  • a reciprocating motion of the armature on the balance spring is transmitted to the balance, and conversely, the movement of the balance on the balance spring controls the movement of the armature and thus the release of the teeth of the escape wheel.
  • armature and balance there are no other elements required for synchronization and power transmission between armature and balance, such as fork and ellipse.
  • no security elements such as anchor pin, safety knife, etc. are required.
  • In operation in comparison to a classic (Swiss) anchor escapement, due to the resilient connection of the armature there are practically no impacts between the armature and the escapement wheel.
  • the balance spring attached to the armature is deflected in the radial direction in the region of its attachment to the armature.
  • the armature rotates about an armature axis
  • the armature axis is mounted stationary with respect to the movement
  • the escape wheel is rotatably mounted about its axis and driven by a drive wheel.
  • the armature rotates about an armature axis
  • the armature axis is mounted on a pivot arm
  • the pivot arm is rotatably mounted about the axis of the escape wheel.
  • the axis of the escapement wheel here is the symmetry axis (with respect to rotational symmetry) and must, since the The escapement wheel may be mounted fixed with respect to the movement, not an axis around which the escapement wheel can physically rotate.
  • the different axes (armature axis, axis of the escapement wheel, axis of the balance) are preferably parallel to each other. This allows the armature to wander around the escapement wheel on the pivot arm. This is realized with simple means a tourbillon. Due to the low mass of the rotating system of arm and armature - which are elastically decoupled from the rest of the spring - occur in comparison to a traditional tourbillon with rotating bogie - correspondingly low impact between anchor pallets and escape wheel.
  • the escape wheel is thus firmly mounted with respect to the movement, but can be disassembled, for example by means of a clamp connection.
  • the rotary arm is driven in its movement about the axis of the escape wheel by a drive wheel.
  • a balance and a coaxially rotatably mounted to the balance rotating element the balance on at least one side (viewed in the axial direction) mounted on an axle is, which is fixedly mounted with respect to the clockwork, wherein the rotary member is rotatably mounted about the axle pin.
  • the rotary element corresponds to the bogie of the tourbillon.
  • This coaxial bearing of balance and rotating element is thus independent of the aforementioned drive the balance by the coil spring and the rotating armature. But if it is realized in combination, then the rotary element corresponds to the rotary arm, which carries the anchor.
  • the escape wheel is then preferably mounted between the balance and the rotary arm on the axle pin. Preferably, the escape wheel is fixed by clamping on the axle pin so that it can be removed for maintenance.
  • the balance has a bearing stone moved along with the balance, which rests on the tip of the axle pin. This is a storage of the balance with a standard quality respectively low friction possible.
  • the bearing block is elastically mounted in the balance to protect against bumps, in particular by a coaxial to the axis of the balance coil spring. This ensures, together with a shock protection (for example incabloc) of a shaft journal at the opposite end of the balance shaft, a shock-proof bearing of the balance on both sides, without a balance shaft having to pass through the rotary element as far as a circuit board of the movement.
  • a shock protection for example incabloc
  • the rotary member with bearing elements in particular with a pair of annular bearing blocks as a bearing bush, rotatably mounted about the axle pin.
  • This is a simple, low-friction and not realized - such as a ball bearing - susceptible to dust storage of the rotary member.
  • the communication with the balance 101 (triggering, impulse transmission) runs only via the coil spring 102. Thus, there is no impulse via an anchor fork and a lever as usual.
  • the described inhibition can also be realized with a non-fixed escapement wheel 106 which is rotatable about its axis.
  • the escape wheel 106 is driven as in a conventional inhibition, and the armature 103 is not mounted on a revolving rotary arm 104 but fixed.
  • a rotating armature 103 so as a tourbillon, but other benefits are possible.
  • a bogie carries the escapement wheel, the armature and the point of attachment of the coil spring.
  • the rotary arm 104 carries only a very small anchor-shaped part 103 to which the spiral spring outer end is fastened.
  • Another advantage of this inhibition is that it gives only one-sided impulse per period. This is a similar effect to a chronometer escapement, but with the benefit of being self-starting.
  • a one-sided pulse has the great advantage that the disturbance of the period is less than one Double-sided drive (the normal lever escapement), which makes the accuracy much better.
  • the pivot arm 104 which carries the spiral spring outer end of the armature 103, moves stepwise, with the pivot point in the balance center.
  • the coil spring 102 is also tensioned, in addition to the above-mentioned tension by the rotation of the armature 103 about the armature axis.
  • the coil spring 102 is tensioned in two ways: first radially over the movement of the armature (armature-shaped part) 103, and secondly tangentially over the movement of the rotary arm 104.
  • the balance shaft is in the way, whereby one is forced to attach a bearing bush to the balance axis. This may not touch the balance axle even with punches.
  • the bogie bearing for the tourbillon is realized around the balance axis, whereby one obtains an undesirably large and fault-prone bearing diameter. For example, a large bearing diameter requires a ball bearing and is accordingly prone to dust.
  • This problem is solved according to one aspect of the invention by removing the lower part of the balance spring and installing the corresponding bearing, preferably with a shock-proof lock, into the balance 101.
  • This is exemplary in FIG. 2 in combination with the inhibition shown above.
  • the storage is designed, for example, for impact protection with one or more spring-loaded storage stones 112.
  • a bearing of the balance in an upper plate 107 is shown schematically only with a further bearing block 116.
  • a thin axle 109 or axle pin, fixed to the lower board 108 can be used, on which this bearing sits, and around which the bogie (in a conventional tourbillon) respectively the rotary arm 104 (corresponding to the here presented escapement, in which the thin axis 109 is coaxial with the rotational arm axis 114) are mounted.
  • the outer end of this thin axis 109 ie at the of the Sub-board 108 opposite side
  • Both the balance 101 and the bogie respectively the rotary arm 104 are thus supported on thin, simple and robust bearings.
  • the rotary arm 104 can be rotatably mounted around the axle pin 109 with, for example, a pair of annular bearing blocks 115 as a bearing bush.
