Definitions
- the present invention relates to a clockwork, in particular a clockwork with a microgenerator.
- the present invention also relates to a test method for such movements.
- the present invention is based on the finding that, surprisingly, this is not the case. In such watches, severe signs of wear appear after a short time:
- An object of the invention is to build a clockwork with a microgenerator in which these problems do not occur.
- Another goal is to build a clockwork with a microgenerator that is at least as durable as a conventional mechanical clockwork.
- Another goal is to build a cheap and also reliable clockwork that is regulated by a generator and in which these wear problems do not occur.
- the rotor receives a position torque that is significantly greater than the drive torque that is available on the generator, which causes the generator to stop.
- the axis in question was now made of copper berylium (CuBe). This solution has already been described in the above-mentioned application EP0851322. Copper-berylium tends to form oxide layers. If this oxide layer is thick enough and the surface pressures in the transmission are small, the rotor 10 and the wheel 51 and the pinion 50 (Inter 2) which drives the rotor can be electrically insulated from the rest of the clockwork.
- the pinion 50 and the wheel 51 are now electrically insulated from the other parts of the clockwork, they can become electrically charged by frictional electricity and / or by stray fields of the rotor which induce a voltage in the wheel 50-51. As soon as the voltage reaches a certain value, sparking can occur, as described later, which can cause faster wear of the gear train and rapid destruction of the lubrication.
- the insulated wheels and the rotor can be charged in particular by friction electricity. When two surfaces are in contact and then separate, electrons are carried away from one surface. As a result, one body is negatively charged, the other positively. If the bodies are not electrically isolated from one another, the charges are simply exchanged again the next time they are contacted.
- the rotor 10 If the rotor 10 is now electrically isolated from the rest of the clockwork, which could be proven by measurements of the electrical resistance between the circuit board 30 and the rotor 10, it charges up, be it through air friction, through charge separation as described above or by induction of voltage in the wheel 50-51 through the magnetic stray fields of the rotor 10.
- discharges occur. These can be spark discharges in the tooth mesh, but other discharges can also occur, for example directly between the rotor 10 and the circuit board 30. These discharges cause the following damage to the clockwork:
- the electronics 81 may be disturbed by the discharges.
- the transmission is grounded in a first embodiment of the invention. This prevents the rotor and the gear from being charged electrically.
- the gearbox can be grounded, for example, via the tooth mesh, or via the
- Axes for example in the bearings or by means of sliding contacts on the axes.
- charge separations are prevented.
- Charge separation can be prevented, for example, by using materials that have approximately the same electrochemical potential and / or the same dielectric constant. If the materials that are in contact with one another have roughly the same surface properties, the tendency is not very great that electrons are entrained when the materials are separated. For example, materials or surfaces that have good tribological properties and a hardness greater than 200HV can be used.
- an oil is used which is resistant to ozone. This allows that To keep lubrication intact even if ozone is regularly produced by radio waves within the clockwork.
- bearing stones are used which protect the oil as well as possible against oxidation. This is achieved by closing the jewels as much as possible so that the oil is held in the bearing by the capillary action and on the other hand so that the oil is not exposed to oxygen and any ozone that may be present.
- Figure 1 shows a cross section through part of the transmission and the micro-generator of a clockwork.
- Figure 2 is a plan view of a module equipped with a micro-generator and the associated electronics.
- FIG. 1 shows a side section of a microgenerator mounted in a clockwork according to the invention, only the parts of the clockwork necessary for understanding the invention being shown.
- the movement contains a mechanical energy store in the form of a spring, not shown.
- the spring is wound by an elevator device, not shown, or preferably by a mass vibrated by the movements of the watch carrier arm.
- the spring drives the various hands and displays of the watch, in particular the second hand, which is mounted on the second axis 70, via a conventional gear (not shown).
- the second wheel 71 mounted on the second axis 70 drives a first intermediate pinion 60 (Inter 1), which in turn drives a second intermediate pinion 50 (Inter 2) via the first intermediate wheel 61.
- the first Intermediate pinion 60 and its axis are made, for example, of steel or another suitable metal; the second intermediate pinion 50 and its axis, on the other hand, are made of a non-magnetizable material, preferably a copper-beryllium alloy, so that a position torque is not exerted on the generator due to the force of the magnet on the intermediate wheel.
- the second pinion 50 in turn drives the axis 10 of the rotor of the generator via the second intermediate gear 51 and the pinion 15.
- the axis 10 is held between two synthetic shock-absorbing bearings 31 and 41 rotating.
- the first shock-absorbing bearing 31 is connected to the circuit board 30 of the factory, while the second shock-absorbing bearing 41 is connected to a bridge 40.
- the rotor consists of an upper disk 11 and a lower disk 13, which are firmly connected to the axis 10.
- the lower surface of the upper disk 11 contains six individual magnets 12, which are arranged at regular intervals near the periphery of the disk.
- the upper surface of the lower disk 13 is equipped in the same way with six individual magnets 14, which are arranged symmetrically to the six magnets of the upper disk.
- the stator contains three induction coils 20, 21 and 22, which are mounted between the disks 11 and 13.
- the generator is mounted between the circuit board 30 and a bridge 40, which allows the entire generator including the coils to be hidden.
- FIG. 2 shows a top view of the module 80 equipped with a micro generator.
- the three coils 20, 21, 22 of the stator of the microgenerator are mounted on the module 80 and connected in series between the points 800 and 803 of the electronic module 80.
- An IC 81 is mounted on the module 80. The purpose of this IC is to monitor the speed of rotation of the microgenerator and to regulate this speed by the value of a variable load resistance is changed by the IC with which the microgenerator can be loaded.
- an oxide layer can be formed on the wheel 51 and the copper beryllium pinion 50 which electrically isolates these wheels from the other wheels 61, 71 and from the circuit board 30.
- This problem exists especially in clockworks with a micro-generator, because the forces between the wheels and thus also the surface pressure during engagement are very small, so that there is no good electrical contact between the wheels.
- the forces in a mechanical watch are approximately of the same order of magnitude, the unrest that regulates the speed is electrically connected to the circuit board by means of the spiral spring, so that it cannot charge up.
- Embodiment of the invention at least a part of the wheels 51, 61, 71 and pinion 50, 60, 70 grounded. Materials or coatings which have very good electrical contact properties are preferably used for the wheels, so that no strong surface pressure is necessary to produce good electrical contact.
- the formation of charge separation is prevented by using materials in the transmission which have approximately the same electrochemical potential and / or the same dielectric constant. If the materials that are in contact with each other are roughly the same surface quality, the tendency is not so great that electrons are entrained when the materials are separated.
- a material or at least a surface for the wheels and pinions 50, 51, 60, 61, 70 and / or 71 is used, which at the same time prevents charge separation and also allows electronic contact in the case of weak surface pressure between wheels.
- a material is preferably used which has good electrical properties, on which no oxide layer forms and which also has good tribological properties.
- wheels and pinions made of a cheaper material can be used, such as plastic, CuBe, aluminum, brass or steel (for wheels and pinions that are not affected by the magnetic field of the rotor), which are then coated with a carefully selected material become.
- the layer thickness is preferably less than 1 ⁇ m, the hardness greater than 200HV, the coating material must not be magnetic and must adhere well to the base material.
- a combination of materials must be used in which the base material of the gears does not diffuse into the coating.
- the coating can consist, for example, of gold, a gold alloy or electrically conductive oxides.
- wheels and pinions made entirely of gold, silver, an electrically conductive material, Ceramicor, an electrically conductive plastic or a similarly good conductive material can also be used.
- the teeth on the wheels and pinions must not be epilamized, since the Epilam acts like an insulator.
- the transmission can also be grounded through the axles.
- Rubies which are good electrical insulators, are normally used to store axles in the watch industry.
- a bearing material 41 is used which has good tribological properties, but also electrically is leading. In this way, the gear unit can also be grounded via the bearing points.
- lubrication is used in the bearings, for example in the form of an electrically conductive grease or oil, so that the gear can be grounded via the bearing points.
- the oil used is also resistant to ozone, so that the lubrication remains intact longer, even if radio waves occur.
- a dry lubricant or a mixture of oil and a dry lubricant can also be used.
- jewels or rubies are used which protect the oil as well as possible against oxidation by oxygen or ozone. This is achieved by closing the bearing stones as far as possible so that the oil is held in the bearing by the capillary action on the one hand and on the other hand so that the oil is not exposed to oxygen and any ozone that may be present.
- bearings which are designed in such a way that the oil is completely protected against oxidation.
- bearing elements can be used, inter alia, for the generator, for the Inter 2 and the Inter 1.
- Duofix, Duobil and Duokif bearing stones from KIF Parechoc AG which have capstone plates that hold the oil in an almost closed space.
- Such bearings also have the advantage that the oil remains better in the bearing due to the capillary action compared to the bearing stones normally used and has less tendency to run out.
- oils can also be used that do not have a very high surface tension, such as perfluorinated oils such as the Fomblin Z 25.
- the present invention also relates to a test method which can be used to check whether wheels in a clockwork are earthed. With this test procedure different materials and coatings can be tested.
- the functioning clockwork that is being tested is bombarded with electrons in a scanning electron microscope SEM. Parts that are not electrically grounded are charged. Now if certain parts, for example the rotor and the pinion / wheels 50/51 are electrically isolated from the circuit board or other components, these parts will charge up until the voltage at any point in the gear train becomes so great that a discharge by a spark. At this point there is a little damage. In this way it can now be determined whether the wheels are grounded. If the clockwork in the REM runs perfectly for a certain time and no damage to the wheels can be determined after this test, this means that the wheels are electrically connected.
- an electrical charge is applied to the rotor without contact.
- a high-voltage source is connected to the clockwork by connecting one pole to the circuit board 30 and positioning the other pole as close as possible to the rotor 10, 11, 13. If there is a spark on the rotor, the rotor is charged electrically. When the rotor and the gear train are electrically grounded, the charges are distributed in the clockwork and there is no reason for a spark between the gears that are in mesh with each other. This means that no damage should be visible on the gears. If, however, the gearwheels are not well connected to each other electrically, a spark can occur in the meshing of the teeth. In this case, the teeth will be damaged.
- the resistance between the rotor and the circuit board is measured.
- the spring must be wound so that the gears are engaged and the surface pressure in engagement corresponds approximately to the surface pressure that is necessary for normal operation.
- the rotor must not be subjected to high mechanical loads, since otherwise the anti-shock elements are deflected and the rotor axis is electrically connected to the circuit board.
- the best way to measure is with a thin wire that contacts the rotor. The rotor must be brought to a standstill by touching the wire.
- the present invention also relates to watches that have been tested using these test methods.
