In mechanical clock, when the action torque from barrel to release catch transmission changes along with the uncoiling of the mainspring barrel of barrel, the pivot angle of escapement changes, and the rate of clock and watch changes.Therefore,, for the change of the action torque that suppresses to transmit to release catch, what proposed to configure sliding attachment (torque adjustment clockwork spring) between barrel and release catch determines torque mechanism (torque adjustment arrangement).Determine torque mechanism and be roughly divided into the mode (for example, with reference to patent documentation 2) of utilizing the mode (such as with reference to patent documentation 1) of flywheel and being accompanied by the periodic Control of cam etc.
For the invention of patent documentation 2 determine load device (torque adjustment arrangement), use the term and the label that in patent documentation 2, use to describe.The load device of determining of the invention of patent documentation 2 possesses scroll spring (torque adjustment clockwork spring) 18 at the 3rd moving member (No. three wheels) 9.The outer circumference end of scroll spring 18 with stop taking turns 22 links, the interior Zhou Duanyu adjustment component 20 of scroll spring 18 links.Stop taking turns 22 main shafts with respect to the 3rd moving member 9 (No. three axles) 8 and be fixed, adjustment component 20 can be rotated with respect to the main shaft 8 of the 3rd moving member 9.Adjustment component 20 utilizes friction to support the 2nd parts (No. three gears) 10.
The 3rd moving member 9 is connected with the 1st second moving member (No. four wheels) 13, and within the 1st second, moving member 13 is connected with the 2nd second moving member 25 with escape wheel 2.Main shaft at the 2nd second moving member 25 is fixed with cam 26, and disposes control claw 31 to clip the mode of the periphery of cam 26.The 2nd fork 32 is from control claw 31 to stopping taking turns 22 extensions.The end engaging of the 2nd fork 32 is in stopping taking turns the sawtooth that 22 peripheries form.
Be accompanied by the uncoiling of scroll spring 18, to the 2nd parts (No. three gears) 10 that are supported on adjustment component 20, give action torque, thus mechanical clock action.Be accompanied by the action of mechanical clock, cam 26 rotates together with the 2nd second moving member 25.Utilize the rotation of cam 26, control claw 31 and the 2nd fork 32 reciprocating rotations, the 2nd fork 32 repeats to stop taking turns 22 engaging and releasing with specified period.During engaging is disengaged, stop taking turns 22 utilizations and roll tightly torque from the next timing of the mainspring barrel transmission of barrel 1, scroll spring 18 is rolled tightly a certain amount of.Like this, the scroll spring 18 of determining load device returns to the amount of rolling tightly of regulation in each specified period.Utilize this scroll spring 18 to make mechanical clock action, the rate of mechanical clock is stable thus.
Figure 11 is the curve map that the relation of clockwork spring torque and rate is shown.As shown in figure 11, because the rate of mechanical clock is along with clockwork spring torque changes, so in possessing the mechanical clock of torque adjustment arrangement, the setting of the amount of rolling tightly of sliding attachment becomes important.Therefore,, at determining in load device of the invention of patent documentation 2, can adjust the loaded-up condition (amount of rolling tightly) of scroll spring 18.Particularly, adjustment component 20 possesses carrying plane 41, and is formed with tooth portion in the periphery of carrying plane 41.And, be adjacent to dispose with adjustment component 20 and control moving member 42, at control moving member 42, be formed with the band tooth mill pinlon 44 meshing with the outer peripheral teeth portion of carrying plane 41.

Fig. 2 is the key diagram of the torque adjustment arrangement 6 of the 1st embodiment, is the planimetric map of state of gear train support plate of removing the face side of movement 5.Fig. 3 is the sectional view along the A1-O-P-Q-A2 line of Fig. 2.In Fig. 2 and Fig. 3, for easily with the aid of pictures, omitted the diagram of the part in the timepiece that forms movement 5.As shown in Figure 2, the movement 5 of mechanical clock possesses: mainspring barrel (not shown), and it is disposed at the inside of driving wheel on barrel 10 and becomes power source; Train (driving wheel on barrel 10,30, No. four wheels 40 of 20, No. three wheels of No. two wheels), it is for transmitting the power of mainspring barrel; Release catch 50(escape wheel 51, escapement lever 56), it moves train off and on; And speed regulator (escapement 58), it periodically moves release catch 50.As shown in Figure 3, these all parts be configured in form substrate base plate 8 and and the gear train support plate 9 of base plate 8 arranged opposite between.
Mainspring barrel is disposed at the barrel inside of driving wheel on barrel 10.
As shown in Figure 3, driving wheel on barrel 10 possesses barrel gear 14 in the periphery of barrel.No. two wheels 20 possess with No. two mill pinlons 22 of barrel gear 14 engagement and with No. two gears 24 of No. two mill pinlon 22 interlocks.No. three wheels 30 possess with No. three mill pinlons 32 of No. two gears 24 engagements and with No. three gears 34 of No. three mill pinlon 32 interlocks.No. four wheels 40 possess with No. four mill pinlons 42 of No. three gears 34 engagements and with No. four gears 44 of No. four mill pinlon 42 interlocks.10 to No. four wheels of driving wheel on barrel 40 form the speedup train of transmitting the power of mainspring barrel and rotating speed being increased.In addition, No. four wheels 40 are corresponding with the second hand 4c of Fig. 1.
As shown in Figure 3, escape wheel 51 possesses and the escapement mill pinlon 52 of No. four gear 44 engagements and the escape wheel 54 linking with escapement mill pinlon 52.As shown in Figure 2, escapement lever 56 possesses a pair of pallet stone 57 engaging with the tooth of escape wheel 54.Escapement 58 possesses hairspring 59.
As shown in Figure 2, under the state engaging with the tooth of escape wheel 54 at a pallet stone 57 of escapement lever 56, escape wheel 51 temporarily stops.When from this state, escapement 58 utilizes the expansion of hairspring 59 to shrink and during rotation, the striker pin that is fixed on balance staff is rotated escapement lever 56.Thus, a pallet stone 57 of escapement lever 56 departs from from escape wheel 54, and escape wheel 54 rotations are to the position that is sticked in another pallet stone 57 of escapement lever 56.The rotatablely moving of intermittence of utilizing such escape wheel 54, release catch 50 moves train off and on.And due to periodically whirling vibration of escapement 58, so speed regulator periodically moves release catch 50.
As previously mentioned, when a pallet stone 57 of escapement lever 56 departs from from escape wheel 54, escape wheel 54 is released this pallet stone 57, and escapement lever 56 swings escapement 58 thus.Thus, from escape wheel 54, to escapement 58, give action torque, maintain the whirling vibration of escapement 58.
(the 1st embodiment, torque adjustment arrangement 6)
As shown in Figure 3, if the action torque of transmitting to release catch 50 from driving wheel on barrel 10 changes along with the uncoiling of mainspring barrel, the pivot angle of escapement changes, and the rate of clock and watch changes.In order to suppress the change of such action torque, movement 5 possesses the torque adjustment arrangement 6 of having assembled sliding attachment (torque adjustment clockwork spring) 65 the train from driving wheel on barrel 10 to release catch 50.
Torque adjustment arrangement 6 possesses: torque adjustment arrangement main body 60, and it possesses sliding attachment 65; Release catch 70 for torque adjustment, the action of its controlling torque adjusting gear main body 60; The amount of rolling tightly adjusting mechanism 80, it adjusts the amount of rolling tightly of sliding attachment 65; And powershift mechanism (planetary gears 90), it is assembled in train and links with the amount of rolling tightly adjusting mechanism 80.In the 1st embodiment, torque adjustment arrangement main body 60 is assembled in No. four wheels 40, and powershift mechanism is assembled in No. three wheels 30.
(torque adjustment arrangement main body 60)
Fig. 4 is the key diagram of torque adjustment arrangement main body 60, is the sectional view along the B1-O-Q-B2 line of Fig. 2.In Fig. 4, the parts of one rotation are applied to identical profile line.As shown in Figure 4, torque adjustment arrangement main body 60 possesses: sliding attachment (torque adjustment clockwork spring) 65; Ratchet (driving wheel on barrel side torque adjustment with wheel) 64, itself and peripheral end (the 1st end) link of sliding attachment 65; And output gear (release catch side torque adjustment with wheel) 66, itself and interior all ends (the 2nd end) link of sliding attachment 65.
Ratchet 64 is fixed on mill pinlon 42 No. four, and can rotate by the axle 41 with respect to No. four wheels 40 together with No. four mill pinlons 42.Periphery at ratchet 64 is formed with ratchet.
Output gear 66 is fixed on the axle 41 of No. four wheels 40, as aforementioned No. four gears 44 performance functions.
The peripheral end of sliding attachment 65 is fixed on ratchet 64 by the 1st fixed part 64f, and the axle 41 of No. four wheels 40 is fixed in interior all ends by the 2nd fixed part 61.Thus, interior all ends of sliding attachment 65 and output gear 66 link.
(release catch 70 for torque adjustment)
As shown in Figure 2, torque adjustment possesses with release catch 70: cam 72, and itself and escape wheel 51 link; Cam follower 74, itself and cam 72 link; Bar 76, itself and cam follower 74 link; And a pair of pallet stone 77, they are fixed on bar 76 and engage with the ratchet of ratchet 64.
Cam 72 is fixed into coaxial shape with respect to the axle of escape wheel 51.Cam 72 forms roughly polygon-shaped when overlooking.Especially, cam 72 forms roughly polygon-shaped (being general triangular shape in the present embodiment) with odd number of apexes.
Cam follower 74 possesses a pair of fork across cam 72 when overlooking.The end of a pair of fork is disposed at cam 72 peripheries in the mode across cam 72 center.The interval of a pair of fork forms less than 2 times of the distance from cam 72 center to the summit of periphery.Cam follower 74 forms axle 75 rotations that can leave around the axle from escape wheel 51 configuration.
Bar 76 links with cam follower 74, and forms and can around axle 75, rotate together with cam follower 74.Bar 76 possesses a pair of arm that is radiated entends in the mode across axle 75 when overlooking.End at a pair of arm is fixed with respectively pallet stone 77.Pallet stone 77 forms and can engage with the ratchet of ratchet 64.
Torque adjustment arrangement main body 60 and torque adjustment are described with the action of release catch 70.
Sliding attachment 65 is rolled tightly ormal weight in advance.When a pallet stone 77 of bar 76 engages with ratchet 64, the rotation of ratchet 64 temporarily stops.Under this state, because output gear 66 is because the uncoiling of sliding attachment 65 is rotated, so supply with action torque via output gear 66 to release catch 50 from sliding attachment 65.Thus, mechanical clock action.
Be accompanied by the rotation of the escape wheel 51 of release catch 50, cam 72 rotations.Be accompanied by the rotation of cam 72, cam follower 74 is around axle 75 reciprocating rotations.When bar 76 and cam follower 74 are in linkage when axle 75 rotates, a pallet stone 77 of bar 76 departs from from ratchet 64, thereby ratchet 64 can rotate.Owing to regularly rolling tightly torque, from mainspring barrel, to ratchet 64, transmit, so ratchet 64 regularly rolls tightly torque rotation by this, and roll tightly sliding attachment 65 between ratchet 64 and output gear 66.Then, thus until another pallet stone 77 of bar 76 engages the rotation stopping period of ratchet 64 with ratchet 64, sliding attachment 65 is rolled tightly ormal weight.This ormal weight is set as until the uncoiling amount that sliding attachment 65 is rolled tightly again.
Like this, because sliding attachment 65 is periodically rolled tightly ormal weight, so sliding attachment 65 remains on the roughly fixing amount of rolling tightly.Due to from this sliding attachment 65 to release catch 50 and speed regulator (escapement 58) supply with roughly fixing action torque, so speed regulator can make the sampling action of release catch 50 to fix.Thus, can improve the precision of clock and watch.And, due to the sampling action of release catch 50 to fix, thus torque adjustment with release catch 70 also with release catch 50 sampling action to fix in linkage.Thus, sliding attachment 65 can be rolled tightly with the cycle of fixing, the precision of clock and watch can be further improved.
In addition, the in the situation that of the complete uncoiling of mainspring barrel, cannot roll tightly sliding attachment 65.Expectation possesses the mechanism of the uncoiling amount of restriction sliding attachment 65, even so that also not uncoiling completely of sliding attachment 65 in this case.As the example of this mechanism, expect limiting the counterrotating mechanism of ratchet 64 and output gear 66.But this mechanism forms, when the amount of rolling tightly of aftermentioned sliding attachment 65 is adjusted, allow the relative rotation of ratchet 64 and output gear 66.
(amount of rolling tightly adjusting mechanism 80)
Figure 11 is the curve map that the relation of clockwork spring torque and rate is shown.Usually, the rate of mechanical clock changes along with clockwork spring torque, and exists posture poor in the rate of mechanical clock.Make dial plate in upper and lower posture (flat-hand position), rate is steady with respect to the variation of clockwork spring torque, but makes table hat towards upper and lower erecting in posture (vertical position), and rate becomes large with respect to the variation of clockwork spring torque.In Figure 11, clockwork spring torque is near R portion time, and the rate of flat-hand position and vertical position equates, but clockwork spring torque is near S portion time, compares with flat-hand position, and the rate of vertical position significantly reduces.
As shown in Figure 3, in possessing the torque adjustment arrangement 6 of sliding attachment 65, sliding attachment 65 remains on the roughly fixing amount of rolling tightly, and the torque (clockwork spring torque) of therefore moving is roughly fixing.Here, in order to be controlled in specialized range posture is poor, by sliding attachment 65 be set in regulation roll tightly quantitative change obtain important, to supply with the action torque of regulation from sliding attachment 65.In addition, when the manufacture of mechanical clock, can expect, under the state by the phase differential configuration ratchet 64 with regulation and output gear 66, sliding attachment being assembled between the two, thereby during fabrication sliding attachment 65 is set for to the amount of rolling tightly of regulation, but this operational difficulty.Therefore, torque adjustment arrangement 6 possesses the amount of the rolling tightly adjusting mechanism 80 of adjusting afterwards the amount of rolling tightly of sliding attachment 65 in the manufacture of mechanical clock.
Fig. 5 is the key diagram of the amount of rolling tightly adjusting mechanism 80, is the sectional view along the C1-C1 line of Fig. 2.The amount of rolling tightly adjusting mechanism 80 shown in Fig. 5 possesses: the amount of the rolling tightly adjustment part 80a(amount of rolling tightly is adjusted screw 81, the 1st amount of rolling tightly regulating wheel the 82, the 2nd amount of rolling tightly regulating wheel 84), the amount of rolling tightly is adjusted torque and is transfused to and is passed to this amount of rolling tightly adjustment part 80a; The amount of rolling tightly maintaining part 80b(retarding spring 85), it keeps the amount of rolling tightly of sliding attachment; With the amount of the rolling tightly display part 80c(amount of rolling tightly show needle 86, the amount of rolling tightly display scale 87), it shows the amount of rolling tightly of sliding attachment.
The amount of rolling tightly adjustment part 80a possesses the amount of rolling tightly and adjusts screw 81, the 1st amount of rolling tightly regulating wheel 82 and the 2nd amount of rolling tightly regulating wheel 84.The upper surface of adjusting screw 81 in the amount of rolling tightly is formed with the slot part engaging with the amount of rolling tightly adjustment instrument.The amount of rolling tightly is adjusted screw 81 and is fixed on the 1st amount of rolling tightly regulating wheel 82, the 1 amount of rolling tightly regulating wheels 82 and the 2nd amount of rolling tightly regulating wheel 84 engagements.The 2nd amount of rolling tightly regulating wheel 84 be assembled in No. three planetary gears 90 in wheel 30 and link.The amount of rolling tightly is adjusted screw 81, the 1st amount of rolling tightly regulating wheel 82 and the 2nd amount of rolling tightly regulating wheel 84 and is configured between gear train support plate 9 and the amount of rolling tightly adjustment gear train support plate 89.
The amount of rolling tightly maintaining part 80b possesses retarding spring 85.The interior perimembranous of retarding spring 85 rolls tightly regulating wheel 84 with respect to the 2nd and is fixed into coaxial shape.The peripheral part of retarding spring 85 forms, and leaves in the axial direction from the 2nd amount of rolling tightly regulating wheel 84.By gear train support plate 9, press vertically the peripheral part of this retarding spring 85, retarding spring 85 is elastic deformation in the axial direction.Thus, from gear train support plate 9, via 85 pairs of the 2nd amount of rolling tightly regulating wheel 84 effect friction torques of retarding spring, limit the rotation of the 2nd amount of rolling tightly regulating wheel 84, kept thus the amount of rolling tightly of sliding attachment.In addition, if give over the amount of rolling tightly of friction torque, adjust torque, the 2nd roll tightly regulating wheel 84 rotations, therefore can adjust the amount of rolling tightly of sliding attachment.
The amount of rolling tightly display part 80c possesses the amount of rolling tightly show needle 86 and the amount of rolling tightly display scale 87.The base end side of the amount of rolling tightly show needle 86 is fixed on the 2nd amount of rolling tightly regulating wheel 84, and end side forms needle-like, and the amount of rolling tightly show needle 86 is along the surface configuration of gear train support plate 9.On the surface of gear train support plate 9, be formed with the amount of rolling tightly display scale 87.As shown in Figure 2, the amount of rolling tightly display scale 87 is along the track configurations of the end of the amount of rolling tightly show needle 86.The amount of rolling tightly display scale 87 possesses the high range forming with predetermined angular interval and the down scale forming between adjacent high range.At the benchmark high range as reference position, be shown as 0.From benchmark high range, observe, at the high range of a circumferential side, show successively+1 ,+2 ..., at the high range of circumferential opposite side, show successively-1 ,-2 ...In addition, also can adjust screw 81 by the amount of rolling tightly of the amount of rolling tightly adjustment part 80a and replace the amount of rolling tightly display part 80c.In this case, utilize the amount of rolling tightly to adjust the bearing of trend of slot part of the upper surface of screw 81, also can show the amount of rolling tightly of sliding attachment.
Get back to Fig. 5, the amount adjustment method that rolls tightly of the sliding attachment of the amount of rolling tightly adjusting mechanism 80 is described.The amount of rolling tightly of sliding attachment be adjusted at the dispatching from the factory of mechanical clock before or while safeguarding, in the stopping of mechanical clock, carry out.First, make the amount of rolling tightly adjustment instrument be sticked in the groove that the amount of rolling tightly is adjusted screw 81, the amount of rolling tightly is adjusted to screw 81 and give the amount of rolling tightly adjustment torque, make the amount of rolling tightly adjust screw 81 rotations.The amount of rolling tightly is adjusted torque and is adjusted screw 81 to the 1st amount of rolling tightly regulating wheel 82 and the 2nd amount of rolling tightly regulating wheel 84 transmission from the amount of rolling tightly, and makes the 2nd amount of rolling tightly regulating wheel 84 rotations.And then, the amount of rolling tightly adjust torque from the 2nd amount of rolling tightly regulating wheel 84 via planetary gears 90 to ratchet transmission, thereby ratchet rotation and roll tightly sliding attachment.And, by the rotating speed of the utilization amount of the rolling tightly adjustment instrument adjustment amount of rolling tightly adjustment screw 81, can adjust the amount of rolling tightly of sliding attachment.
Here, be accompanied by the rotation of the amount of rolling tightly screw 81, the 2nd amount of rolling tightly regulating wheel 84 rotations, the amount of the rolling tightly show needle 86 that is fixed on the 2nd amount of rolling tightly regulating wheel 84 is rotated.And then, utilize the indicated amount of the rolling tightly display scale 87 of the amount of rolling tightly show needle 86, show the amount of rolling tightly of sliding attachment.Thus, the amount of rolling tightly of sliding attachment does not rely on operator's visual sense, can grasp objectively.Its result is sliding attachment to be set for to the amount of rolling tightly of regulation.
Specifically, make in advance the amount of rolling tightly display scale 87 and roll tightly sliding attachment until this amount of rolling tightly display scale 87 in the situation that from the correspondence table of the action torque of sliding attachment output.Next, from the curve map of Figure 11, obtain the poor clockwork spring torque of posture that realizes expectation.Next, from described corresponding table, obtain the amount of the rolling tightly display scale 87 that realizes this clockwork spring torque.Then, so that the mode of the amount of rolling tightly show needle 86 these amount of rolling tightly display scales 87 of indication rolls tightly sliding attachment 65.Thus, sliding attachment can be set as realizing the amount of rolling tightly of the poor regulation of the posture of expectation.
Yet, between the amount of rolling tightly, clockwork spring torque, the pivot angle of escapement and the posture of rate of sliding attachment is poor, there is substantial connection.Therefore, expect measuring the pivot angle of escapement, and meanwhile the amount of rolling tightly of sliding attachment adjusted, to become the method for the pivot angle of realizing the poor escapement of the posture of expectation.In addition, on the one hand, the amount of rolling tightly of the sliding attachment more pivot angle of plurality of pendulums wheel is larger, on the other hand, if train or release catch exist unfavorable condition the pivot angle of escapement diminish.Therefore, likely exist at train or release catch and exist and under the state of unfavorable condition, sliding attachment is rolled tightly when more than setting, when sliding attachment is rolled tightly into setting, the equal situation of pivot angle of escapement.Therefore,, even if measure the pivot angle of escapement, be also difficult to sliding attachment to be set for the amount of rolling tightly of regulation, and be not easy to find the unfavorable condition of train and release catch.
On the other hand, in the present embodiment, can grasp objectively the amount of rolling tightly of sliding attachment, therefore sliding attachment can be set for to the amount of rolling tightly of regulation.And although sliding attachment is being set for to the amount of rolling tightly of regulation, the pivot angle of escapement is than in the little situation of setting, train can be judged or release catch exists unfavorable condition.Therefore, can find reliably the unfavorable condition of train or release catch.

That is, powershift mechanism (planetary gears 290) possesses: the 1st axle (the 1st sun gear 292a), and itself and output gear 66 link; The 2nd axle (the 2nd sun gear 292b), it links with the amount of rolling tightly adjusting mechanism 80; And the 3rd axle (planet carrier 94), itself and release catch 50 link.In addition, the 1st axle of powershift mechanism, the 2nd axle and the 3rd axle are not limited to described combination with the combination as linking output gear 66, the amount of rolling tightly adjusting mechanism 80 and the release catch 50 of target, and forming any combination can.
Torque adjustment arrangement 206 to the 2nd embodiment specifically describes.
In torque adjustment arrangement 206 as shown in Figure 9, the 1st sun gear 292a of planetary gears 290 is as the output gear 66 performance functions of torque adjustment arrangement main body 60.The 1st sun gear 292a is fixed on the axle 41 of No. four wheels 40.The 2nd sun gear 292b forms can be with respect to axle 41 rotations of No. four wheels 40.Planet carrier 294 forms and can rotate with respect to the axle 41 of No. four wheels 40, and as aforementioned No. four gears 44 performance functions.Planet carrier 294 is supported to a plurality of planetary gears 293 can rotate.Planetary gear 293 possesses and the 1st planetary gear 293a of the 1st sun gear 292a engagement and the 2nd planetary gear 293b meshing with the 2nd sun gear 292b.The 1st planetary gear 293a and the 2nd planetary gear 293b interfix by the axle that connects planet carrier 294.
Action to planetary gears 290 describes.
First, in the action of mechanical clock, the action of transmitting action torque to release catch 50 from sliding attachment 65 describes.In the action of mechanical clock, limited the rotation of the 2nd sun gear wheel 292b of planetary gears 290.
On the other hand, in the action of mechanical clock, to the 1st sun gear 292a, supply with the action torque of sliding attachment 65, thus the 1st sun gear 292a rotation.Be accompanied by the rotation of the 1st sun gear 292a, on one side planetary gear 293 rotations are on one side revolved round the sun, so planet carrier 294 rotates together with planetary gear 293.Thus, from No. tetra-gears 44 of planet carrier 294() to release catch 50, transmit action torque.

; owing to possessing planetary gears 290, so can automatically switch transmission from the amounts of rolling tightly to sliding attachment that adjust torques the stopping of the transmission of the action torque from sliding attachment 65 to release catch 50 in the action of mechanical clock and mechanical clock from the amount of rolling tightly adjusting mechanism 80.Therefore, do not need to remove the link of the amount of rolling tightly adjusting mechanism 80 and train, volume efficiency is excellent.
(the 3rd embodiment)
Figure 10 is the key diagram of the torque adjustment arrangement 306 of the 3rd embodiment, is the planimetric map of gear train support plate of removing the face side of movement.In addition, in Figure 10, omitted the diagram of base plate and gear train support plate.In the torque adjustment arrangement 6 of the 1st embodiment shown in earlier figures 2, torque adjustment arrangement main body 60 possesses ratchet 64, but the torque adjustment arrangement 306 of the 3rd embodiment shown in Figure 10 possesses flywheel 364 these one side differences in torque adjustment arrangement main body 360.In addition, for the part of the structure identical with the 1st embodiment, omit its detailed explanation.
As shown in figure 10, the torque adjustment arrangement main body 360 of the 3rd embodiment possesses: sliding attachment (torque adjustment clockwork spring) 365; Flywheel (driving wheel on barrel side torque adjustment with wheel) 364, itself and peripheral end (the 1st end) link of sliding attachment 365; And output gear (release catch side torque adjustment with wheel) 366, itself and interior all ends (the 2nd end) link of sliding attachment 365.
It is large that flywheel 364 forms moment of inertia specific output gear 366.For example, it is little that the area of the loss of weight portion of flywheel 364 forms specific output gear 366, and it is thick that the thickness of flywheel 364 forms specific output gear 366.
At output gear 366, towards flywheel 364, erect and be provided with pin 366p.At flywheel 364, be formed with the hole 364h that supply and marketing 366p runs through insertion.Hole 364h form No. four wheel 40 week upwards allow the size that pin 366p moves in specialized range.Utilize this pin 366p and hole 364h, relatively rotating of output gear 366 and flywheel 364 is limited in specialized range.
Action to the torque adjustment arrangement 360 of the 3rd embodiment describes.
Under the state temporarily stopping due to the engaging of escapement lever 56 in the rotation of escape wheel 54, the end butt of the pin 366p of output gear 366 and the hole 364h of flywheel 364.
If remove the engaging of escapement lever 56, output gear 366 can rotate together with escape wheel 54.Due to the uncoiling of sliding attachment 365, action torque is in output gear 366, and output gear 366 rotates.Then, from output gear 366, to release catch 50, supply with action torque, mechanical clock action.In addition, until during escapement lever 56 is sticked in escape wheel 54 again, output gear 366 rotation predetermined angulars.
On the other hand, owing to regularly rolling tightly torque, from mainspring barrel, to flywheel 364, transmit, so flywheel 364 also rotates.But, the moment of inertia specific output gear 366 of flywheel 364 large, so flywheel 364 is later than output gear 366 and starts rotation.That is, flywheel 364 is with respect to output gear 366 rotation relatively off and on.Here, the pin 366p that first starts the output gear 366 of rotation departs from from the end of the hole 364h of flywheel 364, and rear flywheel 364 rotations that start rotation are until the end of hole 364h is connected to pin 366p.Output gear 366 rotation predetermined angulars, so flywheel 364 also rotates predetermined angular.Thus, flywheel 364 and output gear 366 between sliding attachment 365 is rolled tightly to ormal weight.
Like this, even in the torque adjustment arrangement main body 360 of the 3rd embodiment, because sliding attachment 365 is periodically rolled tightly ormal weight, so sliding attachment 365 also remains on the roughly fixing amount of rolling tightly.Due to from this sliding attachment 365 to release catch 50 and speed regulator (escapement 58) supply with roughly fixing torque, so speed regulator can make the sampling action of release catch 50 to fix.Thus, can improve the precision of clock and watch.And, due to the sampling action of release catch 50 to fix, so output gear 366 and the flywheel 364 also cycle relative rotation off and on to fix.Thus, sliding attachment 365 can be rolled tightly with the cycle of fixing, the precision of clock and watch can be further improved.
In addition, technical scope of the present invention is not limited to above-mentioned embodiment, is included in the embodiment of in the scope that does not depart from aim of the present invention, above-mentioned embodiment having been made various changes.That is, in embodiment, cited concrete material or layer structure etc. are only examples, can suitably change.
For example, as the mechanism of release catch, be not limited to described pawl formula release catch, can adopt various mechanisms.
