Embodiment
In order to make those skilled in the art person understand better technical scheme of the present invention, be described in further detail below in conjunction with drawings and Examples.
The movement floor plan of the mechanical watch embodiment of the two off-centre of the present invention shown in Figure 1.
Among the figure, the engagement of the tooth axle of driving wheel on barrel E and two wheel components 2, the wheel sheet of two wheel components 2 and the engagement of the tooth axle of escape wheel parts 1 pass to balance spring assembly 9 with power by escapement lever parts 8, realize swinging back and forth of escapement.Escape wheel parts 1 are positioned at the center of movement, and escapement and balance spring have just occupied the movement middle section like this.
Among the figure, the tooth axle engagement of second hand wheel component 4 and the escape wheel parts 1 that are positioned at central authorities also is positioned at 3 directions, and the second hand 4A on second hand wheel component 4 tops just departs from the movement center, is in the position between the center to 3.Therefore our movement is designed to the partial center type of belt drive from the drive mechanism.
Among the figure, the engagement of the tooth axle of the wheel sheet of three wheel components 3 and two wheel components 2, the tooth axle engagement of friction minute wheel 5 and three wheel components 3 also is positioned at 9 directions.Two wheel components 2 are given friction minute wheel 5 with transmission of power.The rubbing hole of minute wheel 6 is enclosed within on the friction mandrel of friction minute wheel 5, and minute wheel 6 meshes with the bull wheel of minute wheel 7; The friction minute wheel 5 by friction force with transmission of power to minute wheel 6.The sliding eye of hour wheel 8 is enclosed within on the sliding axle of minute wheel 6, and hour wheel 8 meshes with the steamboat of minute wheel 7.The hour hands 8A on the minute hand 6A on minute wheel 6 tops and hour wheel 8 tops just departs from the movement center, is in the position between the center to 9.
The main transmission of the two eccentric mechanical watch embodiment of Fig. 2 the present invention shown in being.
Show among the figure with 1 interlock of escape wheel parts escapement lever parts 9 and balance spring assembly 10 arranged.
Show among the figure and wind mechanism, the vertical wheel B that winds the winding arbor drive of handle assembly A rotates, vertical wheel B and small click wheel C engagement, and small click wheel C and big click wheel D engagement drive big click wheel D rotation, realize the motion that winds of clockwork spring.Driving wheel on barrel E is connected with big click wheel D is coaxial, and with the engagement of the tooth axle of two wheel components 2.
Driving wheel on barrel E, big click wheel D and clockwork spring are combined into former moving assembly together, with the gear rotation formula, constantly provide makeup energy for balance and hair spring system by two wheel components 2.
Also show handsetting mechanism among the figure, the castle wheel F that winds the winding arbor drive of handle assembly A rotates, castle wheel F can mesh with transmission wheel G, and the bull wheel engagement of transmission wheel G and minute wheel 7 drives the back gear rotation.The bull wheel of minute wheel 7 simultaneously with the time minute hand the engagement of wheel sheet, realize the pulling needle motion.
Because second hand wheel component 4 no longer is the ring in the middle of the main drive chain, so jitter phenomenon will appear in second hand.In order to eliminate this shake, utilize a second wheel spring 4B to push down the end of second hand wheel component 4 axles.
In addition, we become radial floating with the back gear mechanism design, and the partial structurtes of the wheel shaft that please is minute wheel 3 referring to mounting structure signal and Fig. 4 of the floating type minute wheel 3 of Fig. 3 embodiment of the invention are illustrated.
The dead eye 7B of restriction minute wheel 7 scopes of activities makes at the bottom plate of wrist-watch, and dead eye 7B is used for wheel shaft (7C) is installed, and its internal diameter is larger than the diameter of wheel shaft 7C, so wheel shaft 7C can float in dead eye 7B.The working position of minute wheel 7 guarantees by spring leaf 7A.
The lower semisection of wheel shaft 7C is made the eel-like figure shape, because spring leaf 7A is pressed on the eel-like figure place of wheel shaft 7C, make the gear teeth of minute wheel 7 be close to the gear teeth of transmission wheel G and minute wheel 6, thereby eliminated the back lash between minute wheel 7 and minute wheel 6 and the transmission wheel G, thereby also just eliminated the minute hand 6A starting hysteresis phenomenon after the pulling needle.
Fig. 5 has reflected the effect at the needle deflection watch face center of the embodiment of the invention, and on literal, second hand designs 3 positions, the time, minute hand designs 9 positions.Changed when unalterable, the persond eixis structure of minute, second pin centered by dial plate, be wrist-watch a kind of invention of instruction time.Now with the time, the minute, second pin departs from the time indication mechanism at dial plate center, innovative idea represents common people, allows the Ai Biao family that wears wrist-watch that a kind of aesthetic feeling and novelty are arranged.Also be conducive to design and the variation of wrist-watch outward appearance, change variation, modularization, the spininess structure of wrist-watch style.
Foregoing is preferred embodiment of the present invention only, is not the present invention is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to main design of the present invention and spirit.So protection scope of the present invention should be as the criterion with the covering scope of claim.
