Definitions

  • the present invention relates to a movement, in particular a movement with a microgenerator.
  • the present invention also relates to a test method for such movements.
  • Abrasion has also been observed in areas where the teeth never touch, for example at the tips of the teeth.
  • a lot of abrasion in the oil can be found on the storage stones. The faster that Wheel rotates, the more the oil is destroyed at the bearings of the wheel in question.
  • An object of the invention is to build a movement with a microgenerator in which these problems do not occur.
  • Another goal is to build a movement with a microgenerator that is at least as durable as a conventional mechanical movement.
  • Another goal is to build a cheap and reliable movement, which is controlled by a generator and in which these wear problems do not occur.
  • the present invention also relates to a method for testing the movements according to the invention.
  • the generator 10 the pinion 50 and the wheel 51 are electrically isolated from the other parts of the movement, they can be electrically charged by static electricity and / or stray fields of the rotor which induce a voltage in the wheel 50-51. Once the voltage reaches a certain level, sparking can occur, as described later, which can cause faster wear of the gear train and rapid destruction of lubrication.
  • the insulated wheels and the rotor can be charged in particular by frictional electricity.
  • the rotor 10 charges, whether by air friction, by charge separation as described above or by inducing voltage in the wheel 50-51 by the magnetic stray fields of the rotor 10.
  • the transmission is grounded via the axles. This prevents the rotor and gearbox from being able to charge electrically.
  • the gearbox can be earthed, for example, in the bearings or by sliding contacts on the axles.
  • charge separations are prevented.
  • the generation of charge separations can be prevented by using materials having approximately the same electrochemical potential and / or the same dielectric constant. If the materials in contact with each other have approximately the same surface finish, there is little tendency for electrons to be entrained in the separation of the materials. Thus, for example, materials or surfaces having good tribological properties and a hardness greater than 200HV can be used. In an embodiment according to claim 6, a material is used on which no oxide layer is formed.
  • an oil which is resistant to ozone is used is. This allows lubrication to be kept intact when ozone is regularly produced by radio shock within the movement.
  • bearing blocks are used, which protect the oil as well as possible against the oxidation. This is achieved by keeping the jewels as close together 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.
  • FIG. 1 shows a side section of a mounted in a clockwork microgenerator according to the invention, wherein only necessary for understanding the invention parts of the movement are shown.
  • the movement contains a mechanical energy storage in the form of a spring, not shown.
  • the spring is wound by an elevator device, not shown, or preferably by a brought into vibration by the movements of the Uhrmonarms mass.
  • the spring drives, via a conventional transmission, not shown, the various hands and indicators of the watch, in particular the second hand mounted on the seconds axis 70.
  • the second wheel 71 mounted on the second axle 70 drives a first intermediate pinion 60 (Inter 1), which in turn drives a second intermediate pinion 50 (Inter 2) via the first intermediate gear 61.
  • the first Intermediate pinion 60 and its axis consists for example of steel or other suitable metal; the second intermediate pinion 50 and its axis, however, made of a non-magnetizable material, preferably a copper-beryllium alloy, so that not because of the force of the magnets on the idler a positional torque is exerted on the generator.
  • the second pinion 50 in turn drives via the second intermediate 51 and the pinion 15 to the axis 10 of the rotor of the generator.
  • the axle 10 is held rotating between two synthetic shock absorbing bearings 31 and 41.
  • the first shock-absorbing bearing 31 is connected to the board 30 of the factory, while the second shock-absorbing bearing 41 is connected to a bridge 40.
  • the rotor consists of an upper disc 11 and a lower disc 13, which are fixedly connected to the axis 10.
  • the lower surface of the upper disc 11 in this example includes six individual magnets 12 arranged at regular intervals near the periphery of the disc.
  • the upper surface of the lower disc 13 is equally equipped with six individual magnets 14, which are arranged symmetrically to the six magnets of the upper disc.
  • the stator includes three induction coils 20, 21 and 22 mounted between the discs 11 and 13.
  • the generator is mounted between the clockwork board 30 and a bridge 40, which allows to conceal the entire generator including coils.
  • FIG. 2 shows a top view of the module 80 equipped with a microgenerator.
  • 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 rotational speed of the microgenerator and to control that velocity by the value of a variable load resistor is changed by the IC, with which the microgenerator can be charged.
  • an oxide layer on the wheel 51 and pinion 50 may form copper-beryllium, which electrically isolates these wheels from the other wheels 61, 71 and from the board 30.
  • This problem is especially in movements with a micro-generator, because the forces between the wheels and thus the surface pressure in engagement are very small, so that no good electrical contact between the wheels comes about.
  • the forces in a mechanical timepiece are approximately of the same order of magnitude, in this case the restlessness which regulates the speed is electrically connected to the circuit board by means of the coil spring, so that it can not recharge.
  • At least a portion of the wheels 51, 61, 71 and pinion 50, 60, 70 are grounded.
  • wheels or materials are used for the wheels, which have very good electrical contact properties, so that no strong surface pressure is necessary to make a 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.
  • materials in contact with each other are approximately the same surface finish The tendency is not so great that electrons become entrained in the separation of the materials.
  • a material or at least a surface for the wheels and pinions 50, 51, 60, 61, 70 and / or 71 is used, which simultaneously prevents the charge separation and also allows electronic contact with low surface pressure between wheels.
  • a material which has good electrical properties, on which no oxide layer is formed and which also has good tribological properties.
  • wheels and pinions made of a cheaper material, such as plastic, CuBe, aluminum, brass, or steel (for wheels and pinions that are not affected by the magnetic field of the rotor), may be coated with a carefully selected material become.
  • the layer thickness is preferably less than 1 micron, the hardness greater than 200HV, the coating material may 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 may for example consist of gold, a gold alloy or electrically conductive oxides. But it can also wheels and pinions are completely made of gold, of silver, of an electrically conductive material, of Ceramicor, of an electrically conductive plastic or a similarly good conductive material can be used.
  • the teeth of the wheels and pinions must not be epilated because the epilam acts like an insulator.
  • the gear can also be earthed through the axles.
  • rubies which are good electrical insulators, are used for axle mounting in the watch industry.
  • a bearing material 41 is used, which has good tribological properties, but also electrically is conductive.
  • the gear can also be grounded through the bearings.
  • 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 according to the invention, so that the lubrication remains intact longer, even if radio shocks occur. It is also possible to use a dry lubricant, or a mixture of oil and a dry lubricant.
  • bearing stones or rubies are used which protect the oil as well as possible against the oxidation by oxygen or ozone. This is achieved by the bearing blocks are closed as possible, so on the one hand the oil is held by the capillary action in the camp and on the other hand so that the oil is not exposed to the oxygen and the possibly existing ozone.
  • bearing stones for the bearings, which are designed so that the oil is completely protected as possible 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 capillary action makes the oil better in the bearing compared to the normally used bearing stones and less likely to run in the cylinder.
  • oils which do not have a very high surface tension such as e.g. perfluorinated oils such as the Fomblin Z 25.
  • the present invention also relates to a test method with which it can be checked whether wheels are grounded in a clockwork. With this test method different materials and coatings can be tested.
  • the functioning clockwork being tested is bombarded with electrons in a scanning electron microscope SEM. Parts that are not electrically grounded will be charged. Now, if certain parts, such as the rotor and pinions / wheels 50/51, are electrically isolated from the board or other components, these parts will recharge until the voltage at any point in the gear train becomes so great that a discharge takes place by a spark. At this point, then a small damage. In this way it can now be determined whether the wheels are grounded. If the movement in the SEM runs properly for a certain time and no damage to the wheels can be detected 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 movement by the one pole is connected to the board 30, and the other pole as close to the rotor 10, 11, 13 is positioned.
  • the resistance between the rotor and the 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, which is necessary for normal operation.
  • the rotor must not be heavily loaded mechanically, otherwise the anti-shock elements are deflected and the rotor axis is electrically connected to the board. It is best to measure with a thin wire that contacts the rotor. The rotor must be brought to a standstill by the contact with the wire.
  • the present invention also relates to watches that have been tested with these test methods.
