DEVICE FOR ADJUSTING ANGULAR VELOCITY OF WHEEL ASSEMBLY IN CLOCK INCLUDING MAGNETIC TRIGGER MECHANISM Russian patent published in 2018 - IPC G04B15/00 

FIELD: instrument engineering.

SUBSTANCE: group of inventions refers to a device for controlling the relative angular velocity between a magnetic structure and a resonator, which are magnetically connected to each other and form an oscillator that forms a trigger mechanism. Magnetic structure includes at least one annular chain formed of a magnetic material, one physical parameter of which correlates with the magnetic potential energy of the oscillator, the magnetic material is disposed along the annular magnetic circuit in such a way that said physical parameter varies in the angular direction in a periodic manner. Ring chain includes, at each corner period, a zone of accumulation of the magnetic potential energy of the oscillator adjacent to the impulse zone in the radial direction. Magnetic material in each accumulation zone is arranged in such a way that the physical parameter of said magnetic material gradually increases in the angular direction or gradually decreases in the angular direction.

EFFECT: technical result is an increase in the isochronism of the device.
