Mechanical timer travel-time system of balance gear-cover coordinating series

Abstract

Frequency conversion inseries hairspring or balance wheel-hairspring module in hairspring frequency conversion series, and cap teeth unit in variable teeth series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing actual number of teeth and round rotation angle position of head sheave by altered number of teeth of the cap teeth clip, 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 cap teeth unit. 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 the mutual cooperation series of hairspring cover gears. 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 manufacture...

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.
