Abstract
The utility model provides an indication mechanism for the energy of a mechanical watch spring. A gear shaft (18) is pressed at the upper end of a spring shaft (19), and can educe the motion of winding up the spring; a wheel shaft (1) is engaged with a spring barrel wheel (17), and can educe the motion of releasing the spring. The motion of winding up the spring can make a guide finger (11) be the clockwise rotation through a friction wheel sheet (21) and a planetary gear train. When the spring can wind up fully, the A end of the limited slot of a guide finger wheel sheet (8) is arranged on a banking pin (12), and the guide finger (11) can stop rotating; when the spring can wind up sequentially (such as an automatic watch), the friction wheel sheet (21) is slid on a central gear (9), and the spring can be relaxed and can make the guide finger (11) be the anticlockwise rotation through a gear transmission and the planetary gear train when the watch is running; when the spring is relaxed completely, the B end of the limited slot of the guide finger wheel sheet (8) is arranged on the banking pin (12), and the guide finger (11) can stop rotating. The energy stored by the spring can be the numerical value indicated on a disk (23) by the guide finger (11) (the numerical value can be indicated with the hour in the picture).
Description
Technical field
A kind of mechanism that can show mechanical watch spring energy store status (clockwork spring degree of tightness state), it relates to the new construction and the new technology of wrist-watch.
Background technology
It is at present, domestic that to have the wrist-watch that shows clockwork spring energy store status (clockwork spring degree of tightness state) still rare.Existing clockwork spring energy indication mechanism, exist many can not satisfactory part.For example, for drawing the bar motion, pressed individual gear in bar axle upper end, external diameter is big, and bar axle and driving wheel on barrel all can't be dismantled.When drawing case releasing movement, on driving wheel on barrel, adorned a cover, destroyed the original structure of driving wheel on barrel, reduced the transmission accuracy and the performance of driving wheel on barrel.The planet circular system complex structure, processing difficulties, poor reliability.Particularly go up bar and can show wheel and put bar and can show wheel, diameter is big, and thin thickness takes turns that sheet is coaxial to stack for two, and friction force is big, with the also difficult assurance of other gear meshing degree of depth, poor reliability.
Summary of the invention
The purpose of this utility model provides a kind of more reasonable structure, and it is more reliable to work, and processes clockwork spring energy indication mechanism more easily.Press a pinion wheel in bar axle upper end, draw the bar motion, do not influence the dismounting of bar axle and driving wheel on barrel.Draw case releasing movement from the barrel gear teeth, do not influence the original structure of driving wheel on barrel, duty and transmission accuracy.Planet circular system does not have two wheel sheets to stack the position of mutual fricting movement, enough depths of engagement is arranged, reliable operation between gear.

Embodiment
Among Fig. 1, bar axle (19), wheel shaft (1) are bearing between bottom plate (16) and the bar clamping plate (20).Tooth axle (18) is pressed on bar axle (19) and goes up (as Fig. 3), and its external diameter is not more than the diameter of bar axle upper end, and therefore, bar axle (19) can assemble as common axle.Tooth axle (18) and friction pulley sheet (21) are meshed, and draw the bar motion with this.Tooth axle (2) is pressed on wheel shaft (1) and goes up (as Fig. 4), and its external diameter is not more than the diameter of wheel shaft upper end, and therefore, wheel shaft (1) can assemble as common wheel shaft.Wheel shaft (1) and driving wheel on barrel (17) are meshed, and draw case releasing movement with this.Wheel shaft (4), (5) are bearing in and can show between train wheel bridge (3) and the bottom plate (16).The last lower support of needle pivot (10) is meant needle splint (7) and bottom plate (16), and install its upper end can show pointer (11).Fig. 5 is friction pulley sheet and planet circular system structural drawing: tie-rod wheel sheet (6) sky is enclosed within on the sun gear (9), and end play is by showing train wheel bridge (3) and bottom plate (16) limits.Sun gear (9) sky is enclosed within on the needle pivot (10).Friction pulley sheet (21) is pressed on the sun gear (9) with the mode of sliding friction, and it can be with sun gear (9) to rotate together, also can go up at sun gear (9) and slide.Planetary gear sheet (15) is pressed on the planet tooth axle (13), and tooth axle (13) sky is enclosed within on the planet wheel spindle (14), and wheel shaft (14) is pressed on the tie-rod wheel sheet (6).Banking pin (12) is pressed on the pointer clamping plate (7), and the stopper slot A-B interior (as Fig. 6) of pointer wheel sheet (8) is inserted in the lower end, and the pointer wheel sheet is pressed on the needle pivot (10).
Fig. 2 is the pointer index map, and the scale value on the dial plate (23) is represented the energy (with hour representing, also can represent with the clockwork spring number of turns among the figure) of clockwork spring.The apparent pointer (11) of energy clockwise rotates the expression clockwork spring and tightens state, rotates counterclockwise clockwork spring relaxation state when representing to take the needle.The stored energy of the indicated present clockwork spring of numeric representation of pointer (11) (hour).
The course of work: when wrist-watch by last ratchet (22) when tightening clockwork spring, bar axle (19) is being with tooth axle (18) to rotate counterclockwise, by friction pulley sheet (21), sun gear (9), make planetary gear sheet (15), planet tooth axle (13) except that around axle (14) counterclockwise the rotation, also do counterclockwise around needle pivot (10) and involve rotation with tie-rod wheel sheet (6).Because the effect of planet circular system, needle pivot (10) is being with pointer (11) to clockwise rotate, and the expression clockwork spring tightens state.When the stopper slot A of pointer wheel sheet (8) end (Fig. 6) came to banking pin (12), pointer pointed to " 60 ", and pointer wheel sheet (8) stops operating, on the clockwork spring full (bar table on hand), and the stop motion of last bar system.For automatic watch; because arm in the motion that does not stop, tightens clockwork spring also the carrying out that does not stop, in fact; at this moment clockwork spring has been gone up full; clockwork spring will slide in barrel, and friction pulley sheet this moment (21) is gone up slip at sun gear (9) under tooth axle (18) drives; the forwinding wheel of back is motionless; so friction pulley sheet (21) plays the safeguard protection effect to mechanism.When wrist-watch moves, clockwork spring loosens, driving wheel on barrel (17) rotates counterclockwise, be with tie-rod wheel sheet (6) to rotate counterclockwise by wheel shaft (1), tooth axle (2), wheel shaft (4), (5), at this moment sun gear (9) is motionless, planetary gear sheet (15) removes along sun gear (9) and rolls, and around wheel shaft (14) counterclockwise outside the rotation, also does counterclockwise around needle pivot (10) together with tie-rod wheel sheet (6) and involves rotation.Because the effect of planet circular system, needle pivot (10) is being with pointer (11) to rotate counterclockwise, and shows the clockwork spring relaxation state.When the stopper slot B end (Fig. 6) of pointer wheel sheet (8) came to banking pin (12), pointer pointed to " 0 ", and pointer wheel sheet (8) stops operating, and clockwork spring loosens fully, and wrist-watch stops walking.Because last ratio of gear and put the bar ratio of gear and equate, so angle that pointer (11) turns over when going up bar clockwise and the angle that turns over counterclockwise when putting bar equate.Pointer (11) on dish indicated numeric representation the stored energy of present clockwork spring (among the figure with hour represent).
For safety, the ratio theoretical value that the stopper slot A-B angle of actual pointer wheel sheet (8) is done is big slightly, in order to avoid stuck phenomenon takes place in mechanism.
