Description

P1zobreten1: e refers to devices for maintaining a stable drive torque in the trigger balance controllers used in devices for technical purposes or when investigating the dependence of the oscillation amplitude of the oscillator on the moment on the axle of the traveling wheel.

The known clock mechanism contains a balance oscillator with a spiral, a running wheel and a pulse stabilizer, made in the form of an additional spiral, one end of which is fixed to the axis of the traveling wheel.

The disadvantage of this clock mechanism is the lack of feedback between the balance oscillator and the winding mechanism of the additional spiral, as a result of which the change in the oscillation period of the oscillator, for example, due to external influences, changes in friction in the supports, etc., cannot be compensated by changing the drive torque on the axle of the traveling wheel. In addition, when winding the additional spiral from the main spring motor, the frequency of winding is such that the length of the working section of this spiral is very large, which leads to insufficient stability of the pulse transmitted to the oscillator.

The dependence of the oscillation amplitudes of the oscillator on the moment of the drive on the axis of the traveling wheel is practically difficult to implement.

The aim of the invention is to increase the stability of the pulse. The goal is achieved by the fact that the impulse stabilizer is equipped with a pinch motor, on the rotor of which the other end of the additional spiral is fixed, and in its supply circuit through the converter

A balance oscillator position sensor is connected.

The proposed mechanism is shown schematically in the drawing. Spiral 2, balance 3 and

a roller 4 with a pulley 5, which interacts with a fork 6 of an anchor motion converter, which receives the drive torque through the travel wheel 7. On the axis of the travel wheel, an additional spiral 8 is fixed at one end, the other end of which is pinned in a block on the rotor 9 of a stepper motor 10. In a chain the motor power is connected in series with capacitive sensor 11 and amplifier-converter 12.

Instead of a capacitive sensor, for example, a piezosensor or any other position sensor can be used.

whether 8 at a certain angle. For this, several pulses are applied to the engine 10 when the balance 3 is locked. The drive torque generated by the coil 8 on the wheel axle 7 is transmitted, as in conventional release controls, through the fork 6 to the balance 5 to maintain its undamped oscillations.

When the balance 3 rotates at the maximum angle, the sensor 11 via the amplifier-converter 12 outputs a signal to the stepper motor 10, which performs one step and at the same time twists the helix 8. Thus, during the balance oscillation 3 the helix 8 is recharged twice during the period. Due to this, the length of the working section of the helix 8 is significantly reduced and the pulses transmitted by the oscillating system become much more stable. As a result, the accuracy of the instrument is improved.

The winding 8 at the beginning of work, i.e., with a fixed balance of 3 M, at a different angle, ensures the operation of the oscillator at different values of the established amplitude. This will make it possible to obtain the dependence of the oscillations of balance 3 on the drive moment on the travel wheel 7, which is necessary when studying balance oscillators and descents.
