Description

A kind of ball-type difference in specific gravity automatic winding mechanism of mechanical watch

Technical field

The utility model relates to a kind of automatic winding mechanism of mechanical watch, specifically, relates to a kind of ball-type difference in specific gravity automatic winding mechanism of mechanical watch.

Background technology

The automatic winding device of mechanical watch, no matter be low-grade or high-grade, remain so far and adopt automatic hammer automatic winding device.The structural shape of automatic watch is more, but principle of work is roughly the same.Automatic winding device is arranged on the movement back, opens bonnet and can see, causes thus the automatic watch movement generally all thicker.The automatic watch of general reverse wheel structure is comprised of autoplugger (weight), reverse wheel, reducing gear, automatic great wheel etc.Autoplugger is screwed on the autoplugger axle of center.Under the effect of external force, it is around central rotation, drives reverse wheel, and the commutation axle tooth promotes again reducing gear and rotates, and reducing gear promotes automatic great wheel, and great wheel and the engagement of big click wheel tooth automatically make tooth ground rotation of tooth of big click wheel and upper.Full automatic watch is that automatic top rotates and can go up bar to either direction.Be different from unidirectional reversing arrangement, two-way reversing arrangement or ratchet wheel pawl type device.Take full-automatic wrist-watch now as many.The ETA2892 movement, two lion 46941 movements are exactly two-wayly automatically to wind up, the overwhelming majority is with eccentric pendulum top (automatically top or claim automatic weight), the dish of its a shape picture semicircle, select the heavier metal of mass ratio to make, and edge is thicker, so most of quality is all on the edge of top, utilize the swing of the gravitation in the earth's core and human arm and rotate, and driving one group of gear to remove to roll tightly clockwork spring to go up bar.

The shortcoming of this mechanism is: this kind of automatic winding device must be arranged on movement back and movement stack, inevitably increased the thickness of movement, reduced the comfort that people wear wrist-watch; Simultaneously, the weight center is connected with movement by a screw, and stressed concentrating, be prone to the screw extraction fault.

The utility model content

In order to solve the problems of the prior art, the difference in specific gravity that the utility model provides a kind of ball that utilizes Different Weight to produce drives bar on movement and has reduced the ball-type difference in specific gravity automatic winding mechanism of wrist-watch integral thickness and failure rate.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of ball-type difference in specific gravity automatic winding mechanism of mechanical watch, comprise rounded movement body, with the movement body edges, be solidified as a whole and its outside and the locating ring flushed outside the movement body, be connected and form the adjustment ring of positioning gap with locating ring with the locating ring outside is adjustable, its outside is subject to spacing and its inboard ball-type actuating mechanism with ring gear of positioning gap, and nibbles with ring gear the gear of merging into movement body outputting power.

Further, described ball-type actuating mechanism comprises that inboard has the supporter ring of ring gear, several draw-in grooves that are circumference uniform distribution in the supporter ring outside, and corresponding each draw-in groove setting be subject to the spacing ball of positioning gap, wherein, the ball of half is light ball, the ball of half ball of attaching most importance to, and all light balls are adjacent successively respectively with heavy ball, and the diameter of all balls all equates.When the quantity of ball is even number, the quantity of light ball and heavy ball equates; When the quantity of ball is odd number, light ball proportion ball many one or heavy balls all can than many one of light ball.

As preferably, described light ball is made by aluminium, magnesium, beryllium or its alloy material, or selects other light materials (as nonmetal as plastics etc.), or in it, is made as hollow.

As preferably, described heavy ball is made by osmium, iridium, platinum, gold or its alloy material, or selects other heavy materials, and it is set to solid usually.

Further, the described locating ring outside is provided with external thread, and described adjustment ring inboard is provided with the internal thread with this external thread coupling.

Again further, the side of described locating ring and adjustment ring formation positioning gap also is provided with spacing chamfering.

Design concept of the present utility model is, utilized the difference in specific gravity around the ball generation of the Different Weight that is arranged on the movement edge, when the wrist-watch position is changed, the potential energy converting and energy of ball is kinetic energy, and export to realize automatic winding for the movement body provides power, being reached for machinery is the purpose of wrist-watch stored energy.

Compared with prior art, the utlity model has following beneficial effect:

(1) principle that the utility model utilizes the ball of Different Weight to produce difference in specific gravity by it around being arranged on the movement body edges, replaced being arranged in the existing machinery wrist-watch weight at its back side, attenuate the thickness of timepiece movement, improved the comfortable wearing sense, and avoided the stressed burden of weight axle, reduced fault, there is substantive distinguishing features and progress, and the utility model has been simple in structure, design ingenious, with low cost, there is market application foreground widely, be applicable to applying.

(2) the utility model, by the ball collar winding is put, can be presented in face of the user rolling of ball comparatively intuitively, can also see that when the user sees the time ball rotates, and has improved the sight of wrist-watch.
