Abstract:
     Frequency conversion inseries balance wheel or balance wheel-hairspring module in balance wheel 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 number of teeth of the cap teeth unit, and changing actual number of teeth of headgear as well as changing round rotation angle position of head sheave, changing oscillation frequency of balance wheel-hairspring module by altered inertia form basic timing quantity of mechanical timer in mutual cooperation series of balance wheel and cap teeth unit. Advantages are: enriching production specifications, and shortening production cycle.
