Abstract: |
|||
| Hairspring in frequency conversion series or assembly of escapement-hairspring in hairspring frequency conversion series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing length or rigidity of hairspring changes oscillation frequency of hairspring in frequency conversion series or assembly of escapement-hairspring in hairspring frequency conversion series so as to form mechanical timer in hairspring frequency conversion series determined by basic timing quantity in hairspring frequency conversion series. Advantages are: enriching production specifications, and shortening production cycle. | |||
