<p>#CMT# #/CMT# The resonator has an escape wheel (6) engaged with a finishing gear so as to enable the escape wheel to be driven by an energy source of a timepiece. The wheel has permanent magnets (61-66) arranged in a manner, such that vibrations of one of arms (2, 3) of a diapason-type oscillator (1) control rotational speed of the wheel, and are periodically propagated by magnetic interaction between permanent magnets (4, 5) of the oscillator and the permanent magnets of the wheel in order to define free escapement. #CMT#USE : #/CMT# Mechanical magnetic resonator for horlogical movement of a mechanical timepiece (all claimed) i.e. Accutron(RTM: tuning fork type wrist watch). #CMT#ADVANTAGE : #/CMT# The wheel has permanent magnets arranged in a manner such that vibrations of one of the arms of the diapason-type oscillator control rotational speed of the wheel, and are periodically propagated by magnetic interaction between the permanent magnets of the oscillator and the permanent magnets of the wheel in order to define the free escapement, thus ensuring high quality factor of the resonator. The resonator performs optimized operation due to nature of the retaining interaction between the oscillator and the escape wheel and the possibility of adjusting the magnetic properties of the permanent magnets, and recovers the sufficient amount of energy to ensure the maintenance of the vibrations of the oscillator with better isochronism. The magnetic resonator has high durability. The resonator is constructed and assembled in a simple manner. The resonator's construction allows simple integration into an existing watch caliber without requiring major changes into the watch caliber. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified front view of a mechanical resonator with a magnetic escapement, in a configuration, comprising an escape wheel placed between arms of a U-shaped diapason-type oscillator. 1 : Diapason-type oscillator 2, 3 : Arms 4, 5, 61-66 : Permanent magnets 6 : Escape wheel.</p> |
