Balance-spring variable frequency series mechanical timer travel time system

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.

Description

Technical field: [0001] The invention relates to a mechanical clock / timer, in particular to a mechanical timer whose product specification is determined by the basic timing quantity of a hairspring frequency conversion series. Background technique: [0002] The structure and technical processing method of the existing mechanical timer still remain at the level of original technology so far, and the specifications of the product are extremely monotonous. [0003] In terms of product structure, although the number of teeth of each paired gear, the ratio of paired gears of each paired gear set, the number of total rotation cycles of the last wheel of the transmission gear group, the number of teeth of the escape wheel, and the total cumulative rotation of the teeth of the escape wheel The number of teeth, swing frequency, basic timing amount, selected timing amount setting range and other related production technical data are different among different manufacturers, but they ar...

Problems solved by technology

With the continuous expansion of its variety and specifications, it is far from meeting the needs of the growing international and domestic markets. The contradiction between supply and demand between mechanical timer technology and products and the market has become increasingly prominent. Customers can only supply products with different specifications. That is to say, at present, every domestic manufacturer of mechanical timers is still unable to serve customers on demand.
