Abstract:
     Frequency conversion inseries hairspring or balance wheel-hairspring module in hairspring frequency conversion series, and cap teeth unit in variable teeth series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing actual number of teeth and round rotation angle position of head sheave by altered number of teeth of the cap teeth clip, 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 cap teeth unit. Advantages are: enriching production specifications, and shortening production cycle.
