Embodiment Construction

[0014] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described.

[0015]As shown in Figure 1, the head gear 28 with the shaft end 26 passed through by the head wheel shaft 59 and synchronously mechanically connected with the head gear 28 equipped with the variable tooth series cover gear 63 and the spring hook 57 inserted into the spring 54 and the spring by the shaft end 56 The head wheel of the cover gear variable gear series formed by end 58, the two wheel shafts 52 pass through the two small gears 27 and the two large gears 53 of the interconnected body with the shaft ends 22 or 51, and the two wheels and the three wheel shafts 20 formed by the shaft ends 17 or 48 pass through the three wheels formed by the three small gears 24 and the three large gears 46 that are connected to each other, and the final wheel shaft 15 passes through the mutual synchronous mechanical coupling final gear 42 and the escape wheel 16 with th...

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...
