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.

Embodiment Construction

[0012] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described.

[0013] Such as figure 1 As shown, the head wheel shaft 59 passes through the shaft end 26 and is synchronously mechanically connected with the head gear 28 provided with the variable tooth series cover gear 14 and the shaft end 56 clockwork hook 57 is inserted into the clockwork 54 and the inner end 58 of the clockwork. The completed cover gear changing gear series head wheel, two wheel shafts 52 pass through the interconnected second small gear 27 and two large gears 53 with shaft ends 22 or 51, and the two wheels and three wheel shafts 20 formed by shaft ends 17 or 48 The three small gears 24 and the three large gears 46 that pass through the parallel body form the three wheels, the final wheel shaft 15 passes through the final gear 42 and the escape wheel 16 that are connected with each other synchronously with the shaft end 13 or 44, and the final wheel ...

Abstract

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 unit form basic timing quantity of mechanical timer in series of 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 a gear changing gear 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 are all determi...
