Definitions
- the present invention relates to a constant force device for precise gear control of mechanical movements by means of a even power transmission from the escape wheel to the regulating element of the watch, this device being integrable into a tourbillon mechanism.
- constant force devices have been known for some time and mostly become a certain preload at any time owning additional spring, which realizes the by the decaying tension the tension spring variable drive of the clockwork replaced and is periodically tightened by a certain, constant quantity. While their voltage reduction to maintain the vibration of the The watch's regulating element can transmit the force transmitted as being far more constant can be viewed as the sole drive of the regulator only via the Mainspring.
- the escape wheel is in this Case controlled by a first anchor and periodically released, which at Anchor escapement is common. At the same time, the escape wheel is above one Driven by a so-called constant wheel and also oversteers a Reuleaux cam a second anchor, which in turn engages with a stop wheel.
- This stop wheel is concentric with that named constant wheel, which gives an approximately constant torque to the Regulators passes, arranged, one between these wheels preloaded coil spring is placed, which by mutual rotation these wheels are subject to said periodic re-tensioning.
- the CH 120028 patent also specifies such a constant force device represents, with the biased additional spring between the stop wheel and finds the escape wheel arranged concentrically to this. In this case gives the escape wheel an almost constant torque to the regulator further.
- the transmission of an almost constant torque is based despite different design of the device and a different arrangement the associated anchor essentially on the same principle as the above Execution. While conventional constant force devices of this type definitely deliver improvements, such as one no longer due to the sluggishness of the Wheel movement influenced inhibition, the possibility of the wheel train appropriate construction to beat in full seconds, and in particular to achieve the transmission of a relatively constant torque, there are various disadvantages.
- the aim of the present invention is to overcome the aforementioned Difficulties as well as in particular the transfer of one actually constant torque to the regulator of the watch as well as the Consideration of the non-concentric placement of the Stop wheels relative to the constant torque wheel and advantages in integration in a tourbillon mechanism.
- the subject of the invention is a constant force device, which is characterized by the features listed in claim 1.
- the attached figures exemplify an embodiment a constant force device according to the present invention.
- Figure 1 is a top view of one with an inventive Constant force device equipped tourbillon mechanism.
- Figure 2 shows the tourbillon mechanism including the Constant force device in section along the line A - A according to Figure 1.
- Figure 3 shows the essential components for better understanding the device without the tourbillon cage as in Figure 1 in a plan view.
- FIG. 4 is a top view of the main part of FIG Constant-force device.
- FIG. 5 is a section of the constant force device along the line A - A according to Figure 4, about the integrated force compensation mechanism there in detail display.
- FIG. 6 schematically illustrates the functioning of the Force balance mechanism.
- the Tourbillon mechanism shown in Figure 1 is a Constant force device integrated according to the present invention.
- the Tourbillon mechanism has a tourbillon cage 1, one in the center Balance 2 is rotatably mounted, a coil spring 3, a drive wheel 13 and a fixed second wheel 14, and possibly a not shown, concentric to this second fixed second wheel with a different number of teeth or of different diameters.
- the fixed second wheel 14, or if it is present, the second fixed Second wheel is in engagement with a stop wheel drive 12a, which with a Stop wheel 12 is firmly connected and not rotatable in the tourbillon cage 1 is appropriate.
- This stop wheel 12 has in the reproduced here Embodiment two teeth, one with the anchor pallets 11 a and 11 b cooperate second anchor 11 of the constant force device, which in the example shown pivoted in the axis of the tourbillon mechanism is appropriate.
- Said anchor 11 is by means of a fork-shaped Anchor pallets 11 a and 11 b of the opposite part 11 c of this anchor 11 controlled by a Reuleaux cam 5, the Reuleaux cam 5 the shape an equilateral triangle, the three sides of which are circular sections instead of lines form, owns. These three sides of the Reuleaux cam 5 cooperate on conventional manner with the fork-shaped part 11c of the armature 11 to its To control swivel movements.
- the Reuleaux cams 5 part of another complex of the constant force device, which in turn is not centered in the tourbillon cage 1 and in particular is not attached concentrically to the stop wheel 12.
- the axis of this in the Figures 4 to 6 as a plan view, section and shown in its operation
- the complex is formed by the escape wheel shaft 9, which rotates in the tourbillon cage 1 is embedded and on which in the upper section of the Reuleaux cams 5 and including an escape wheel 6 are attached.
- This escape wheel 6 has the in the customary shaped teeth, thus allowing the movement of the Anchor wheel 6 by means of a seated on the tourbillon cage 1 and by the balance 2 controlled first anchor 4, the two with the teeth of the Lock wheel has alternately engaged anchor pallets to block or release.
- the escape wheel shaft 9 In the lower section of the escape wheel shaft 9 is rotatable about the same Tension ring drive 8 attached to which a tension ring 7 is attached.
- the Tension ring drive 8 is carried by a socket 26 and is analogous to Stop wheel drive 12a in engagement with the fixed second wheel 14, which is when integrated a constant force device according to the present invention in one Tourbillon mechanism the possibilities for the relative location of these two Can specify elements.
- This force balancing mechanism initially has one on the attached to the escape wheel 6 opposite side of the tension ring 7 Force balancing eccentric 20, whose axis is opposite the axis of the Anchor wheel shaft 9 and the axis of rotation identical to the latter Tension ring drive 8 is moved in parallel.
- a force compensation plate 21 is rotatably mounted, which in present example two opposite arms as points of attack (21a, 21b) has, but of course quite different, functionally identical shape can accept.
- the balance wheel 2 is driven by the preloaded Coil spring 10, the reset of the balance by the second coil spring 3.
- the stop wheel 12 as well the cage 1 of the tourbillon mechanism over the Reuleaux cams 5 and second anchor 11 released.
- the stop wheel 12 then rotates one determined by its number of teeth, in the present case by 90 °, and is stopped again by an anchor pallet of anchor 11.
- the energy stored by the tension of this spiral spring 10 can be passed on to maintain the oscillation of the balance 2 in the form of a torque, the tension decreasing until the spring is re-tensioned only slightly, but noticeably for the desired precision.
- the energy transfer therefore takes place by means of the special force balancing mechanism, which ensures the transfer of an actually constant torque.
- the tensioned coil spring 10 fastened at one end to the mobile coil spring roller 22 exerts a force on the pin 25 located in this coil spring roller 22, which pin 25 transmits this force as torque to one of the arms of the force compensation disk 21.
- the other arm of the force compensation disk 21 acts on the pin 25 fastened in the fixed spiral spring roller 23 and thus transmits the torque to this fixed spiral spring roller 23 and the escape wheel 6.
- the escape wheel 6 With each half-oscillation of the balance 2, the escape wheel 6 becomes the first Armature 4 released and rotates under the influence of the tensioned coil spring 10 by an angle ⁇ about its axis, as is the fixed spiral spring roller 23 and the force compensation plate 21, while the tension ring 7 and the stop wheel 12 are blocked.
- the non-concentric arrangement of the Stop wheels relative to the wheel transmitting the constant torque in in this case to the escape wheel 6, various advantages.
- the Constant force device in a tourbillon mechanism can also change the position of the stop wheel around the fixed second wheel can be freely selected, it can be over its drive also with a second fixed second wheel of a different diameter are engaged.
- the - in the described embodiment included - possibility of integrating such a Constant force device in a tourbillon mechanism of great interest, insofar as the complementary properties of these two systems precise control of the clockwork can be combined in an effective manner. So the escapement is no longer influenced by the inertia of the gear train. With appropriate construction, so that the stop wheel once per second released, the mechanism can display full seconds.
- the one Tourbillon mechanism usual blows when stopping the tourbillon cage, which have a detrimental effect on the dynamics are Coil spring and strong due to the introduction of the force balancing mechanism reduced.
- the tourbillon cage is instead of an abrupt stop previously braked.
- the arrangement of the axis of rotation of the second armature is in the Center of the tourbillon cage advantageous. This will influence the Moment of inertia of the tourbillon cage through the anchor in contrast to one avoided elsewhere and optimized the dynamics of the system.
- the exemplary embodiment is in no way restrictive insofar as the additional features shown there such as the non-concentric position of the stop wheel relative to the constant Torque transmitting wheel, the placement of the second anchor in the center of the bogie or integration into a tourbillon mechanism can be omitted or just like the detailed design of the Force balancing mechanism subject to functionally identical changes can.
