Abstract:
     Frequency conversion inseries hairspring or balance wheel-hairspring module in hairspring frequency conversion series, and headgear in variable teeth series or head sheave in variable headgear series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing round rotation angle position of head sheave by altered actual number of teeth of headgear, and changing oscillation frequency of balance wheel-hairspring module by altered length or rigidity of hairspring form basic timing quantity of mechanical timer in mutual cooperation series of hairspring and headgear. Advantages are: enriching production specifications, and shortening production cycle.
