Abstract:
     Frequency conversion inseries balance wheel or balance wheel-hairspring module in balance wheel 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 inertia of balance wheel. Advantages are: enriching production specifications, and shortening production cycle.
