The regulator-pin-free fold frame hairspring speed regulating system changes the elasticity and deformation of the tail end of the hairspring because of the action of the hairspring folds, thereby buffering dramatic eccentric movements of the hairspring, reducing influences imposed on the speed regulating system by an additional force and the force moment, and being capable of effectively improving the travel time quality of watches.
Description
Technical field
The utility model relates to stem-winder technical field, relates in particular to a kind of without card degree pleat frame hairspring governing system.
Background technology
Common mechanical table governing system is made up of escapement and common hairspring, hairspring the inner is fixed on balance staff rotates together with escapement, outer end is fixed on transfixion on stud, when work, hairspring can not keep spiral of Archimedes shape, produce violent eccentric motion, when the additional force and moment of eccentric motion generation is walked to wrist-watch, quality has a strong impact on as tautochronism, potential difference etc. cause.
For above-mentioned deficiency, in medium-to-high grade mechanical watch, adopt without card degree hairspring structure, be by adjusting escapement from the entering and the position that goes out or regulates the rotatable counterweight being placed of uniform screw with it without card degree hairspring structure, thereby change escapement radius of turn reach the object of change vibration period.
Feature without card degree hairspring structure is to have cancelled index lever, escapement design is become to the structure of adjustable its moment of inertia, namely changes the escapement radius of gyration.Generally there are two kinds of basic structures: one is, in escapement outer rim or inner edge, screw or nut are set, far away and near by changing their position from escapement center, thus the radius of gyration of change escapement; Another kind is that rotary counterweight is set in the plane near outer rim at escapement, by rotating the position of counterweight, thereby changes the radius of gyration of escapement.The net result of these two kinds of structures is exactly to change the vibration period by the radius of gyration of change escapement, to reach the object that can adjust mechanical watch timing rate.
Chinese patent literature (the day for announcing: on October 5th, 2005, notification number: CN1677283A) a kind of balance-wheel balance-spring seed-regulating mechanism disclosed, it comprises the upper hairspring filling on balance wheel assembly, balance wheel assembly, also be included in the lower hairspring filling on balance staff between the escapement of balance wheel assembly and two disk, upper hairspring and lower hairspring are forward and reverse installations, and upper hairspring and lower hairspring are same model.The present invention is due to two forward and reverse being arranged on same balance wheel assembly of hairspring, and operation simultaneously, expands or crispatura in the other direction simultaneously, offsets eccentric phenomenon no matter what angle of same time all rises, and solves the error that hairspring bias produces clock and watch completely.
Although technique scheme also can solve the error that hairspring bias produces clock and watch, this technical scheme adopts upper and lower hairspring, and such structure increases the thickness of whole mechanism, part, complex process, and cost increases.
The impact of quality when wrist-watch being walked for solving hairspring eccentric motion, also useful variable cross section hairspring, governing system, also can obtain good result.But variable cross section hairspring must be used silicon materials etching and processing, same part, complex process, cost is higher.
Utility model content
The purpose of this utility model is the problem of quality when solving hairspring eccentric motion and to affect wrist-watch and walk, and provide a kind of simple in structure, cost is low, can change deflection and shape, the buffering hairspring eccentric motion of common hairspring outer end when fixing, reduce eccentric force and moment on governing system impact without card degree pleat frame hairspring governing system.
The utility model is realized the technical scheme that its technical purpose adopts: a kind of without card degree pleat frame hairspring governing system, comprise the hairspring, hairspring inside stud, hairspring stud, balance staff and the escapement that are arranged in mechanical watch, described hairspring inside stud connects hairspring the inner and is fixed on balance staff, described hairspring stud connects hairspring tail end and is fixed on outer anchor ear, also be provided with eccentric counterweight, described eccentric counterweight rotates and is pressed on escapement, and a section of being arranged on before hairspring stud of the tail end of described hairspring is provided with gauffer.This is without card degree pleat frame hairspring governing system, and hairspring inside stud connects hairspring the inner and is fixed on balance staff, can rotate together with escapement, hairspring stud connects hairspring tail end and is fixed on outer anchor ear, can not rotate together with escapement, eccentric counterweight rotates and is pressed on escapement, rotatably adjusts escapement moment of inertia.Adopt without card degree balance spring structure, that is to say to adopt and cancel the variable hairspring length structure of index lever, adopt the variable escapement moment of inertia of eccentric counterweight structure to adjust timing rate, the impact that adopts eccentric counterweight can also solve hairspring to open shaped as frame shape, hairspring and swing frame situation quality when walking.Simultaneously, at the tail end of hairspring, one section of hairspring gauffer is set, the arranging of this gauffer can change deflection and shape, the buffering hairspring eccentric motion of common hairspring outer end when fixing, reduce the impact of eccentric force and moment on governing system, this changes the design of hairspring tail end structure, neither need to change the material of hairspring, do not need to change the making processing technology of hairspring, only need to adopt conventional hairspring material, processes yet.Increase by one section of folded structure at hairspring tail end, adopt eccentric counterweight, in this governing system when work, is due to the effect of hairspring tail end gauffer, elasticity and the distortion of hairspring end are changed, cushion the violent eccentric motion of hairspring, reduced the impact of additional force and moment on governing system, quality can effectively improve wrist-watch and walk time.And simple in structure, cost of manufacture is low.
As preferably, described gauffer is provided with at least 6, and the described curved structure of multiple gauffers is along the rotation direction setting of hairspring.Gauffer is provided with at least 6, the curved structure of multiple gauffers is along the rotation direction setting of hairspring, the setting of gauffer quantity and structure is to change elasticity and the distortion of hairspring end, cushioning the violent eccentric motion of hairspring, reducing additional force and moment is principle on the impact of governing system, very few effect can be not obvious, quality can not effectively improve wrist-watch and walk time.
As preferably, described gauffer is evenly equipped with 8 to 10.The quantity setting of gauffer, different according to different model balance spring, preferably 8 to 10 gauffers, can change deflection and shape, the buffering hairspring eccentric motion of hairspring outer end when fixing, reduce the impact of eccentric force and moment on governing system, can reduce again manufacture craft, reduce cost of manufacture, improve make efficiency.
