Description
Technical field
The utility model relates to a kind of top flywheel wrist-watch, relates in particular to a kind of double pendulum wheel mechanism of top flywheel wrist-watch.
Background technology
Pseudo-classic top flywheel wrist-watch begins progressively popularly in recent years, and the top flywheel wrist-watch of double pendulum wheel occurred, and its outward appearance novel and beautiful rather attracts eyeball.But because the frequency of two balance spring vibrational systems has minimum difference, present train is to drive respectively two escape wheels by differential attachment, drives two balance spring vibrational systems by two escapement levers respectively by two escape wheels again.Its complicated structure does not obviously improve the timekeeping performance of wrist-watch.
Summary of the invention
The utility model mainly solves the technical matters of original top flywheel wrist-watch double pendulum wheel mechanism complicated structure; A kind of double pendulum wheel mechanism of top flywheel wrist-watch is provided, and it is simple in structure, and it is convenient to realize, keeps equally the wrist-watch timekeeping performance, reaches again the purpose of novel and beautiful.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: the utility model comprise the top flywheel microscope carrier that is subjected to three wheel drive and be located on the top flywheel microscope carrier, by the gear train of escape wheel, escapement lever and the first balance spring module composition, described top flywheel microscope carrier is provided with the second balance spring assembly, decorate escape wheel and fixing ring gear, the first escapement in the second escapement in the second balance spring assembly and the first balance spring assembly is meshed, and the escapement axle tooth, decorates the escapement axle tooth and is meshed with fixing ring gear respectively.The outer rim of the outer rim of the first escapement and the second escapement is the gear of special tooth profile, and intermeshing when balance spring equilibrium position separately.After the moment of watch main-spring begins to be delivered to the first balance spring assembly by escape wheel, escapement lever, because the first escapement and the second escapement are intermeshing, so these two vibrational systems begin vibration together, and by escapement lever to the first balance spring assembly input makeup energy, to keep the vibration of two vibrational systems.The same with all top flywheels, the rotation of three wheel drive top flywheel microscope carriers, and drive the speed rotation that whole top flywheel comprises that escape wheel, escapement lever, the first balance spring assembly and the second balance spring assembly, decoration escape wheel turn with per minute one together clockwise, improve the wrist-watch timekeeping performance.Because fixedly ring gear is fixed, along with the rotation of top flywheel microscope carrier, escape wheel drives the escapement axle tooth along fixedly ring gear rotation, drives simultaneously to decorate the escapement axle tooth also along fixedly ring gear rotation, thereby realize decorating the idle running of escape wheel, play the beautifying and decorating effect.The utility model is compared with original top flywheel double pendulum wheel mechanism, has omitted some parts, and is therefore simple in structure, and it is convenient to realize, has also reduced cost.
As preferably, described fixedly ring gear and the coaxial setting of described top flywheel microscope carrier, described escape wheel and decorate the both sides that escape wheel is arranged at the central shaft of described top flywheel microscope carrier symmetrically.Constitutional balance, firm, rotation are all even stable, and accurate when guaranteeing to walk, profile is more attractive in appearance.
As preferably, described top flywheel microscope carrier is provided with train wheel bridge and lower plate, train wheel bridge, lower plate all are connected on the top flywheel microscope carrier, described escape wheel, the first balance spring assembly, the second balance spring assembly and decorate escape wheel and be installed between train wheel bridge and the lower plate, and the first balance spring assembly and the second balance spring assembly and escape wheel and decoration escape wheel are all symmetrical mutually take the central shaft of top flywheel microscope carrier as axis of symmetry.Install firmly, whole top flywheel structure is more stable.
The beneficial effects of the utility model are: simple in structure, it is convenient to realize, obviously improves the wrist-watch timekeeping performance, and the outward appearance novel and beautiful, rather attracts eyeball, and also reduces cost.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the double pendulum wheel mechanism of a kind of top flywheel wrist-watch of present embodiment, as shown in Figure 1, comprise top flywheel microscope carrier 2 and be installed on the gear train that is consisted of by escape wheel 3, escapement lever 4 and the first balance spring assembly 5 and the second balance spring assembly 6 on the top flywheel microscope carrier 2, decorate escape wheel 7 and fixing ring gear 8.Train wheel bridge 9, lower plate 10 are installed on the top flywheel microscope carrier 2, escape wheel 3, the first balance spring assembly 5, the second balance spring assembly 6 and decorate escape wheel 7 and be installed in respectively between train wheel bridge 9 and the lower plate 10, and the first balance spring assembly 5 and the second balance spring assembly 6 are symmetrical mutually take the central shaft of top flywheel microscope carrier 2 as axis of symmetry.As shown in Figure 2, the outer rim of the second escapement 61 in the outer rim of the first escapement 51 in the first balance spring assembly 5 and the second balance spring assembly 6 is the gear of special tooth profile, the second escapement 61 and the first escapement 51 are meshed, fixedly ring gear 8 and the 2 coaxial settings of top flywheel microscope carrier, escape wheel 3 and to decorate escape wheel 7 symmetrical mutually take the central shaft of top flywheel microscope carrier 2 as axis of symmetry, as shown in Figure 3, the axle tooth of escape wheel 3, the axle tooth of decorating escape wheel 7 are meshed three-wheel 1 and 11 engagements of top flywheel shaft tooth with fixing ring gear 8 respectively.
After the moment of watch main-spring begins to be delivered to the first balance spring assembly by escape wheel, escapement lever, because the first escapement and the second escapement are intermeshing, so these two vibrational systems begin vibration together, and by escapement lever to the first balance spring assembly input makeup energy, to keep the vibration of two vibrational systems.The same with all top flywheels, the rotation of three wheel drive top flywheel microscope carriers, and drive the speed rotation that whole top flywheel comprises that escape wheel, escapement lever, the first balance spring assembly and the second balance spring assembly, decoration escape wheel turn with per minute one together clockwise, improve the wrist-watch timekeeping performance.Because fixedly ring gear is fixed, along with the rotation of top flywheel microscope carrier, escape wheel drives the escapement axle tooth along fixedly ring gear rotation, drives simultaneously to decorate the escapement axle tooth also along fixedly ring gear rotation, thereby realize decorating the idle running of escape wheel, play the beautifying and decorating effect.The utility model is simple in structure, and it is convenient to realize, obviously improves the wrist-watch timekeeping performance, and the outward appearance novel and beautiful, rather attracts eyeball, and also reduces cost.
