Embodiment
In order to make those skilled in the art person understand the technical scheme of the utility model better, do further detailed description below in conjunction with accompanying drawing and embodiment.
The movement floor plan of the mechanical watch embodiment of the two off-centre of the utility model 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 escapement hairspring assembly 10 with power through escapement lever parts 9, realize swinging back and forth of escapement.Escape wheel parts 1 are positioned at the center of movement, and escapement and escapement hairspring have just occupied the movement middle section like this.
Among the figure, the tooth axle engagement of second wheel parts 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 wheel parts 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; Friction minute wheel 5 is given minute wheel 6 through friction force with transmission of power.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 utility model shown in being.
Show among the figure with 1 interlock of escape wheel parts escapement lever parts 9 and escapement hairspring assembly 10 arranged.
Show bar mechanism among the figure, the upright B that takes turns that the winding arbor of last bar handle assembly A drives rotates, upright wheel B and little steel wheel C engagement, and little steel wheel C and click wheel D engagement drive click wheel D and rotate, and realize the last bar motion of clockwork spring.Driving wheel on barrel E is connected with click wheel D is coaxial, and with the engagement of the tooth axle of two wheel components 2.
Driving wheel on barrel E, click wheel D and clockwork spring are combined into former moving assembly together, with the gear rotation formula, constantly for balance and hair spring system makeup energy are provided through two wheel components 2.
Also show handsetting mechanism among the figure, the castle wheel F that the winding arbor of last bar handle assembly A drives rotates, castle wheel F can mesh with transmission wheel G, and the bull wheel engagement of transmission wheel G and minute wheel 7 drives back gear and rotates.The bull wheel of minute wheel 7 simultaneously with the time minute hand the engagement of wheel sheet, realize dialling needle movement.
Because second wheel parts 4 no longer are the rings in the middle of the main transmission 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 4 of second wheel parts.
In addition, we become radial floating with the back gear mechanism design, are that the partial structurtes of the wheel shaft of minute wheel 3 are illustrated referring to the mounting structure signal of the floating type minute wheel 3 of Fig. 3 the utility model embodiment and Fig. 4 please.
The dead eye 7B of restriction minute wheel 7 scopes of activities makes on the bottom plate of wrist-watch, and dead eye 7B is used to install wheel shaft (7C), and its internal diameter is bigger 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 of falling to dial behind the pin.
Fig. 5 has reflected the effect at the needle deflection watch face center of the utility model embodiment, sees from literal, and second hand designs 3 positions, the time, minute hand designs 9 positions.Changed when unalterable, branch, second hand be the time indicating structure at center with the dial plate, is wrist-watch a kind of invention of instruction time.Existing with the time, branch, second hand depart from the time indication mechanism at dial plate center, innovative idea represents common people, lets the Ai Biao family that wears wrist-watch that a kind of aesthetic feeling and novelty are arranged.Also help the design and the variation of wrist-watch outward appearance, change variation, modularization, the spininess structure of wrist-watch style.
Foregoing is merely the preferred embodiment of the utility model, is not the utility model is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to the main design and the spirit of the utility model.So the protection domain of the utility model should be as the criterion with the covering scope of claim.
