Abstract: |
|||
| Frequency conversion inseries balance wheel or balance wheel-hairspring module in balance wheel frequency conversion series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing oscillation frequency of balance wheel-hairspring module by altered inertia of balance wheel form basic timing quantity of mechanical timer in balance wheel frequency conversion series. Advantages are: enriching production specifications, and shortening production cycle. | |||
