Description
Technical field
The present invention relates to the automatic winding structure of a kind of wrist-watch, particularly relate to the row of a kind of Margarita top wrist-watch
Star wheel series automatic winding mechanism.
Background technology
At present, stem-winder is the most no longer single persond eixis instrument, and is more as a kind of ornaments
Had by consumer.Therefore, in order to win the market, attractive in appearance, novel become watch design person competitively
The target pursued, the movement of various styles the most competitively comes on stage, and wherein " Margarita top " wrist-watch is
One therein.
It is known that energy when stem-winder is walked is to be provided by clockwork spring, it may be assumed that store when clockwork spring rolls tightly
Elastic potential energy is the wrist-watch energy that motion is carried out when walking, and when wrist-watch runs, clockwork spring gradually loosens also
The elastic potential energy that it is stored is converted to mechanical energy and runs offer energy for wrist-watch, after clockwork spring drains,
Elastic potential energy stored by clockwork spring discharges complete the most therewith, and wrist-watch travel time system also will be because losing energy supply
And shut down, in order to ensure when normally walking of wrist-watch, wearer must roll tightly before clockwork spring drains in time
Clockwork spring i.e. supplemental chords." supplemental chords " generally has two kinds of forms, it may be assumed that manually winds up and automatically winds up.On Shou Dong
String, it may be assumed that timing bar on hand carrys out the stem-winder of supplemental chords, commonly referred to " common table ".Automatically wind up,
That is: in general wristwatch, with the addition of a set of additional mechanical automatic winding mechanism, by the pendulum of wearer's arm
Move and the stem-winder of supplemental chords, be referred to as " automation table ".Automatic winding mechanism generally comprise autoplugger,
Train, changement and former dynamic assembly.Its operation principle is: wrist-watch wearer in active procedure,
Autoplugger rotates due to the gravity of self thus drives other parts to rotate with the purpose reaching upper bar.
It is noted that there is the drag angle of an autoplugger in automatic winding mechanism, when the center of gravity of autoplugger exists
Can not complete bar time in the range of drag angle, therefore during design, drag angle can not be the biggest.
For obtaining preferable drag angle, according to drag angle computing formula:Wherein:
Mj is the maximum make-up torque of required clockwork spring；
ε is drag angle；
Pr is automatic hammer body net torque；
I is by the gear ratio of autoplugger to barrel；
η is transmission efficiency.
It is clear that when automatic hammer body statical moment, clockwork spring maximum make-up torque, transmission efficiency one timing,
Increase with gear ratio i is reduced by the size of drag angle, and in order to improve upper string efficiency, design
Person is often desirable to obtain less drag angle.The most so-called common table automatically of our common automatic table, its
Automatically hammer body is typically mounted on the rear capping of timepiece movement, and volume is relatively big, and its radius size is usually equal to
The radius of whole movement, thus quality is relatively big, available bigger net torque Pr；And for " Margarita
Top " wrist-watch, its automatic hypophysis small volume, its radius size ordinarily be about the half of movement radius,
The least, thus quality is less.For the timepiece movement of above two style, in order to obtain size phase
When drag angle, the gear ratio of the automatic hammer body assembly of the latter to former dynamic assembly is greater than the former undoubtedly.
Fig. 1 is the plane of the fixed shaft gear train type of belt drive of existing Margarita top wristwatch automatic winding mechanism
Layout drawing.In figure, automatic hammer body 1 ' connects into the entirety without relative motion with oscillating weight wheel 2 '.
Under gravity, automatic hammer body 1 ' is by the ball bearing 3 ' studded with on oscillating weight wheel 2 '
Rotate around A axle, thus driven automatic one to take turns 4 ', automatic two wheel components 5 ', automatic three
Wheel component 6 ', automatic four wheel components 7 ', automatic five take turns 8 ', changement 9 ', upper bar
Ratchet 10 ' rotates, wherein: described upper bar ratchet 10 ' is connected with former dynamic assembly 11 ', from
And reach to tighten the purpose of clockwork spring.It is not difficult to find out from technique scheme, whole automatic remontoir
Almost occupy the rear capping of whole movement, be unfavorable for that structure when movement designs is arranged.
