Abstract:
     Frequency conversion inseries hairspring or balance wheel-hairspring module in hairspring frequency conversion series, and escape wheel in variable teeth series or end wheel in variable teeth series of escape wheel is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing turned accumulative teeth / number of time in whole course of the escape wheel by altered number of teeth of the escape wheel, 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 escape wheel. Advantages are: enriching production specifications, and shortening production cycle.
