Abstract
The utility model relates to a multi-hairspring speed regulating mechanism for a mechanical watch. The multi-hairspring speed regulating mechanism aims at the solving the technical problem for reducing the defect of timing error caused by eccentricity and overweight of a single hairspring of the traditional mechanical watch. The multi-hairspring speed regulating mechanism is provided with a hairspring (1-1), wherein one end of the hairspring is fixed with a swing axle (4) through an inner pile (1-3), and the other end of the hairspring is connected with an outer pile (1-2). The multi-hairspring speed regulating mechanism is characterized in that the multi-hairspring speed regulating mechanism is provided with a second hairspring (2-1) identical to the hairspring (1-1), one end of the second hairspring (2-1) is fixed with the swing axle (4) through a second inner pile (2-3), the other end of the second hairspring is connected with a second outer pile (2-2), and two groups of structures: the hairspring (1-1)/the outer pile (1-2) and the second hairspring (2-1)/the second outer pile (2-2) are distributed on the plane through being staggered for in 180 degrees.
Description
Technical field
Speed adjusting gear when the utility model relates to walking of a kind of mechanical watch specifically is a kind of many hairsprings of mechanical watch speed adjusting gear.
Background technology
As everyone knows, traditional mechanical watch all adopts a hairspring and an escapement to form speed adjusting gear, and the deficiency that this kind structure exists is: when escapement swings back and forth; Because hairspring the inner is fixed on the escapement; The outer end is fixed on the stud, can not keep original Archimedes's wire shaped, and each circle produces eccentric; The center of gravity of whole hairspring has been destroyed the balance of original system along with hairspring is unfolded, shunk and make complicated motion.When the wrist-watch amplitude of oscillation was big more, the off-centre that hairspring produces and the amplitude of centre-of-gravity motion were just all the more severe, thus the variation that produces the mechanical watch isochronal error.When balance staff was horizontal, the additional moment that the hairspring center of gravity produces can directly be added to again on the hairspring moment, the azimuthal error when having brought the different directions position to mechanical watch.
The utility model content
The technical matters that the utility model will solve is to reduce conventional robot list hairspring off-centre and lay particular stress on the deficiency that causes time error.
Many hairsprings of mechanical watch speed adjusting gear of the utility model, a hairspring, an end of hairspring is fixed with balance staff through interior stake, and the other end of hairspring is connected with stud, it is characterized in that being provided with two hairsprings identical with hairspring; Described two hairsprings, one end is fixed with balance staff through two interior stakes, and the other end of two hairsprings is connected with two studs; The 180 ° of layings that misplace in the plane of hairspring/stud and two hairsprings/two groups of structures of two studs.
Because two hairsprings and hairspring are identical in rotation direction, length, rigidity, when escapement hairspring governing system was started working, two groups of hairsprings were unfolded synchronously or are shunk, the change of its shape and the displacement of center of gravity each moment its numerical value all be identical.But,, cancel each other so its direction is opposite in twos because two groups of hairsprings misplace 180 °.Like this, it is minimum that the variation of walking time error that the speed adjusting gear of two hairsprings just makes original wall scroll hairspring that mechanical watch is produced is tending towards, and reduced the time error of walking of mechanical watch to greatest extent.
Hairspring-stud and two hairsprings-two stud upper-lower position can exchange.
Many hairsprings of mechanical watch speed adjusting gear of the utility model, another technical scheme be, a hairspring, and an end of hairspring is fixed with balance staff through interior stake, and the other end of hairspring is connected with stud, it is characterized in that being provided with two hairsprings identical with hairspring and three hairsprings; Described two hairsprings and three hairsprings, one end are fixed with balance staff through stake in two interior stakes and three respectively, and the other end of two hairsprings and three hairsprings is connected with three studs with two studs respectively; The 120 ° of layings that misplace in the plane of hairspring/stud, these three groups of structures of two hairsprings/two studs and three hairsprings/three studs.
The utility model can reduce the time error of walking of mechanical watch effectively, and enforcement simple in structure is convenient.
