Tent drive

The present invention relates to an electric tent drive with one electronic drive stage and one to be driven Part, such as a mechanical vibrator, and is especially for use in pocket watches, alarm clocks and similar Ze Itanzelge devices.

A well-known time work experience is a permanent magnet with a mechanical vibrator or a rotating part. In a Control coil and a drive coil on the input or output side an electronic amplifier will be used for the tent work Induced voltages required for the vibrator drive. the Clockwork drives either work with a coil induced, sinusoidal voltage or with voltage impulses more defined Width, the perlode of which is essentially given.

In the first operating mode, there is once a driving force per perlode exerted on the vibrator. The live phase of the Drive stage takes a relatively long time, and the resulting Drive angle of rotation is correspondingly large. The result is a low level of efficiency of the drive stage, since the current components that are ineffective for the drive increase sharply. 009887/0469

The use of a small drive rotation angle is a necessary one Demand for the stabilization of the drive period.

The second of the operating modes described above enables no complete two-fold division of the driving force during a perlode. The disadvantages of an unstable mode of action, caused by the irregular waveform of the voltages induced in the coils and by fluctuations in the orbital tent due to temperature changes are avoided by the present invention.

Another feature of the drive stages that have been common up to now is that Starting by self-excitement. Do the way of working between Drive stage and mechanical vibrator are two main types differentiated. In the first case, the oscillation perlode is the Drive level equal to that of the mechanical vibrator while they in the second case differs from this. Starting by self-excitation is easy to implement in the first case. The one that occurs accelerated growth of vibration is with one associated higher power consumption. In the second case, too Power consumption to realize self-excitation starting very high. Another disadvantage is the delayed Increase in vibration at the beginning of the movement,

In a preferred embodiment of the invention, formed from an electric tent and an electronic drive stage, the power consumption is very low even with a very long operating time, so that a small battery as a power source can be used.

According to the invention, the driving force is when the maximum is reached induced voltage amplitude occur and thereby a easy and quick starting through self-excitation at low levels Realized electricity consumption. The timer drive is preferred designed so that the driving force during each

009887 / 0X60

Oscillation period occurs twice and thus the oscillation angle is kept as small as possible. The resulting Power components which are ineffective for the drive are of little welcome. The desired drive mode of the timer takes place under very stable operating conditions. Another advantage of the invention is the use of an astabilon Multivibrators in the drive stage. The desired quick starting through self-excitement is easy thanks to the herstullbaro Synchronization between vibrator vibration and a periodic sweeter oscillation reliably realized. For this reason, attaching a self-starter is the in many known .Bauarten is available, not necessary.

The time constant of the multivibrator used is advantageously chosen very large, so that the ineffective current components flow through this when driving a balance motor.

The double occurrence of the driving force during a period causes a very short current-carrying phase of the drive stage and therefore a very low current consumption of the type according to the invention. The short current-carrying phase increases the further essential efficiency and the stability of the drive stage according to the AIRY theorem.

Preferably dl · frequency of the drive stage, which the growth the oscillation in the starting period through self-excitation accelerated, increased.

Further features, advantages and application possibilities result from the attached illustrations as well as from the following Description.

The inductances and 4 are wound in opposite directions so that the induced th voltages are in phase opposition to each other and have the shape of a disk (see Flg. 2 and 3). The link of the two base resistors 7 and 8 is connected via a manual switch 9 to the positive terminal of a battery 10, the negative terminal of which on ground.

Are resistors used instead of coils 3 and 4 (see Fig. 1), so is the circuit of an astable multivibrator before, whose tent constant is known to be the product of capacity (5 or 6) and resistance (7 or B) is given. The time constant is important in the present invention larger than the oscillation period of the balance wheel, which means its influence by the drive stage largely avoided will. Practical values are e.g. D. 0.4 see for the period of oscillation of the balance wheel and 47 seconds for the tent constant of the astable multivibrator.

When the voltage switch 9 is closed, a large part of the Current of the battery 10 through the resistor 7 or θ and a small amount through the coil 3 or 4 and the capacitor 5 or 6 to the base electrode of transistor I or 2. Which of the both transistors is controlled depends on the differences in the transistor characteristics and has no effect on the present invention.

The transistor 2 conducts z. B. the current during the first half period at the beginning of the oscillation of the balance wheel. It then effects any change in position due to the feedback effect of the multivibrator a shift in the operating point of transistor 1 in the direction of the locking position.

Current flows through the coil 4, and the driving force proportional to it moves the balance wheel in the corresponding direction. The voltages induced in coils 3 and 4 are proportional to the movement of the balance wheel and have a phase difference of 180. Since the transistor 1 remains blocked, the collector voltage is Q _n . equal to the sum of battery voltage E and the induced voltage. When the transistor 2 is conductive, the capacitor 5 is charged in accordance with the polarity shown in FIG. 1.

The balance wheel changes its position in the following half-cycle Direction of movement and thus also the induced voltage Polarity.

The induced voltage in coil 4 holds across the capacitor the base electrode of transistor 1 blocked for a while, If the base voltage exceeds the reverse voltage Vqc (o) (see FIg. 6) the transistor 1 becomes conductive and a current flows through the coil 3, which triggers an additional deflection of the balance wheel.

At the same moment the base electrode of transistor 2 is through the charge of the capacitor 6 is negatively biased, and the transistor blocks. The capacitor 5 is charged in the process.

From the foregoing it follows as an essential voi— part of the invention that the drive stage in accordance with the given frequency of the balance wheel oscillates.

The transistors block and alternately conduct the current, so that twice a drive torque per oscillation is exerted on the balance wheel will.

The interaction of the multivibrator with the possible changes in direction the driving force of the balance wheel causes a Immediate acceleration of the oscillation control and thus that rapid achievement of a stable position.

The drive stage realizes a light, fast and reliable one Self-starting of the arrangement by the switching operations according to the oscillation periods of the balance wheel.

The magnet wheel 34 rotates gradually through the action of the magnetic coupling described above, since the switch + magnet 28 begins to oscillate. The frequency of the step-by-step rotation of the magnet wheel 34 is the same as that of the vibrator arrangement comprising vibrator tongue 29, switching magnet 28 and bar magnet 30. The rotation of magnet wheel 34 can be transferred to a conventional gear transmission that actuates the clock hands (not shown in FIGS. 10 and 11) .

A damping device 35 is arranged on the magnet wheel 34, to stabilize the rotations of the former. One Rough setting of the number of vibrations of the mechanical vibrator is possible by moving a control piece 32 that sits on the solenoid 28. A one-piece 33 is adjustable attached to the control piece 32 with a screw 101. Adjusting the screw 101 enables fine adjustment of the Number of vibrations of the mechanical vibrator.

The rotation speed of the ratchet wheel 53 is through a known anchor lever 54 regulated by a balance wheel 55. A shaft 52 with a gear 51 is in engagement with one Drive pinion 50, which forms a unit with the jamming wheel 53, and is driven at a regulated speed.

The tension of the spring 48 is loosened by the described operation of the ratchet wheel 53, the magnetic coupling again made and the compression spring 48 rewound. This process repeats itself over and over again. The spring 48 is firm connected to one end of the shaft 49. The gearbox 51 is with a wheel (not shown in Fig. 12) of the timer gearbox in connection that the regulated speed on the clock hands (not shown in Fig. 12).

The cylindrical magnet 37a of the rotor 37 (see Fig. 14) forms a four-pole magnet. With one full turn of the The rotor will have two voltage curves of sinusoidal shape and the period TT in the slot 3 or 4 Induced. DIo training of the rotor 37a as a four-pole magnet results in a doubling of the period of rotation of the rotor compared to the period the induced voltage. The resulting voltage and current curves are shown in Fig. 15 a - e.
