Description

Escapement, clock machine core and clock and watch

Technical field

The present invention relates to escapement, clock machine core and clock and watch.

Background technology

In general, there is mechanical clock escapement, the escapement to transmit to balance spring mechanism and be moved for reciprocating rotary Power, and train is controlled with constant vibration using the reciprocating rotary of the rule of balance spring mechanism.In the past, this to catch Vertical machine is repeated improvement etc. and is developed, and has proposed multiple types at present.

For example, one kind as the higher escapement of efficient and durability, it is known to the natural style escapement designed with Breguet Machine (natural escapement) is the escapement of starting.As the escapement of the system, there is following feature：The escapement There are two escape wheels for tool, by being alternately carried out directly impact to balance spring mechanism from the two escape wheels and via escapement lever Indirect stroke, to balance spring mechanism passing power.

In particular, the escapement is different from the fork for the mainstream for occupying mechanical clock tile style/lever escapement, set The sliding for counting into the tooth top of escape wheel in impact is less.Thereby, it is possible to inhibit the abrasion of the tooth top of escape wheel, improve durable Property.In addition, in the case where to balance spring mechanism directly impact, it can be not via other timepieces and from escape wheel Balance spring mechanism is transmitted and is impacted.Hereby it is achieved that efficient.

In addition, when being conceived to from escape wheel to the mode of balance spring mechanism passing power come when distinguishing escapement, substantially It is divided into direct impingement and indirect stroke type, wherein the direct impingement is directly to be passed from escape wheel to balance spring mechanism Graduating power, the indirect stroke type are transmitted indirectly to balance spring mechanism from escape wheel via other timepieces such as escapement lever Power.In addition, it is also known that there are simultaneously using the escapement of directly both impact and indirect stroke.

Balance spring mechanism is the timepiece for the governor for constituting the speed governing for carrying out escapement, it is desirable that with defined vibration Period moves back and forth (vibration).Therefore, under normal conditions in order to inhibit the balance spring mechanism caused by friction etc. to shake The tenon of the decaying of width, balance spring mechanism is formed very carefully.Accordingly, it is considered in the tenon from outside to balance spring mechanism In the case of applying impact, tenon may be deformed or is broken, to cause the precision of balance spring mechanism to reduce or action Stop.

Therefore, in order to prevent caused by from external impact the tenon of balance spring mechanism deformation or fracture etc., The bearing of balance spring mechanism mostly uses the resistance to bearing that shakes.The resistance to bearing that shakes allows balance wheel to swim when being applied in impact with balance spring mechanism Silk mechanism is pivoted bearing in axially and radially upper mobile state to balance spring mechanism.As a result, it is resistance to shake bearing absorb or Mitigate the impact for the tenon for being applied to balance spring mechanism, it is ensured that impact resistance.

As described above, in the case where balance spring mechanism is pivotally supported by the resistance to bearing that shakes, when from escapement to balance wheel When balance spring mechanism passing power, balance spring mechanism largely moves on axially and radially.At this point, for direct For the escapement of impingement, from its action, the engaging of the tooth top and the impulse pallet of balance spring mechanism side of escape wheel Amount is mostly tens μm or so.Therefore, when impacting beginning and at the end of impact, above-mentioned engaging amount further tails off.

Therefore, when from escape wheel to balance spring mechanism direct passing power, make pendulum in the effect by the resistance to bearing that shakes In the case that wheel balance spring mechanism has for example moved radially, the centre distance between escape wheel and balance spring mechanism can become Change, meeting is engaged when tooth top and the engaging of the impulse pallet of balance spring mechanism side of escape wheel may be unstable or worst It falls off.Therefore, it is difficult to ensure the action of the stabilization of escapement, along with escape wheel is first rotated than balance spring mechanism, because It is difficult the unfavorable condition for transmitting power to balance spring mechanism that this, which is easy tod produce,.

Especially in the case where escape wheel is first rotated than balance spring mechanism, sometimes because of escape wheel and escapement lever Mutual phase relation and can not utilize the stoppings fork watt of escapement lever that the rotation of escape wheel be made to stop, it is also possible to causing clock and watch urgency The change dramatically of the step of table etc is walked acutely.

In contrast, for the escapement from escape wheel to the balance spring mechanism indirect stroke type of passing power indirectly For, it is configured to same as fork tile style/lever escapement, is provided with the phase that can make escapement lever and balance spring mechanism sometimes The safety effect of the state before movement is restored to position relationship, even if to make balance spring in the effect by the resistance to bearing that shakes When mechanism for example moves radially, do not allow to be also easy to produce above-mentioned unfavorable condition yet.

For example, Patent Document 1 discloses the escapement of indirect stroke type, the escapement of the indirect stroke type has quilt Being arranged to can be relative to the 1st escapement lever and the 2nd escapement lever of escape wheel engaging/disengaging, but is configured to not allow to be also easy to produce The unfavorable condition stated.In the escapement, the 1st escapement lever can be rotated according to the rotation of balance spring mechanism, be had It can stop fork watt and the 2nd relative to the 1st of tooth top engaging/disengaging of escape wheel and stop fork watt, and having can be with escapement 1st impulse pallet of the peak contact of wheel.2nd escapement lever can be rotated according to the rotation of the 1st escapement lever, and having can With the 2nd impulse pallet of the peak contact of escape wheel.

In escapement recorded in the patent document 1 constituted like this, such as when in the 1st stopping fork watt and escape wheel Under the state (state for making the rotation of escape wheel stop) of tooth top engaging, the 1st escapement lever is pressed by the impulse pallet of balance spring mechanism When pressing and being rotated according to the rotation of balance spring mechanism, the 1st stops fork watt is detached from from the tooth top of escape wheel.The 1st stops as a result, Only fork watt is released from the engaging of the tooth top of escape wheel, therefore escape wheel utilizes and starts to rotate from the power of train.

And then, the 2nd escapement lever is rotated with the rotation of the 1st escapement lever, and the 2nd impulse pallet enters escape wheel Tooth top rotational trajectory on.The tooth top for having begun the escape wheel of rotation as a result, contacts (collision) with the 2nd impulse pallet.By This, the power that can will be transmitted to escape wheel is indirectly transferred to balance spring mechanism via the 2nd escapement lever and the 1st escapement lever, Rotating energy can be supplemented to balance spring mechanism.

Later, when the rotation of the 1st escapement lever and the 2nd escapement lever further carries out, tooth of the 2nd impulse pallet from escape wheel Top is detached from, while the 2nd stops on the rotational trajectory of the fork watt tooth top for entering escape wheel.The tooth top of escape wheel stops with the 2nd as a result, The rotation of only fork watt engaging, escape wheel stops.

Later, balance spring mechanism continues to rotate by inertia, and impulse pallet leaves from the 1st escapement lever.Then, when balance wheel is swum The rotating energy of silk mechanism is when being stored into balance spring completely, and balance spring mechanism is after instantaneously static, by being stored in Rotating energy in balance spring and start to rotate in the opposite direction.

Then, the 1st escapement lever is pressed by the impulse pallet of balance spring mechanism and again according to the rotation of balance spring mechanism It is rotated to negative direction, the 2nd stops fork watt is detached from from the tooth top of escape wheel.The 2nd stops card of the fork watt with the tooth top of escape wheel as a result, Conjunction is released from, therefore escape wheel utilizes and starts again at rotation from the power of train.

And then, the 2nd escapement lever rotates in the reverse direction with the rotation of the 1st escapement lever, and the 1st impulse pallet into Enter onto the rotational trajectory of the tooth top of escape wheel.The tooth top for having started the escape wheel of rotation as a result, is contacted with the 1st impulse pallet (collision).As a result, with it is same before, the power that can will be transmitted to escape wheel is indirectly transferred to balance wheel via the 1st escapement lever Balance spring mechanism can supplement rotating energy to balance spring mechanism.

Later, when the rotation of the 1st escapement lever and the 2nd escapement lever further carries out, tooth of the 1st impulse pallet from escape wheel Top is detached from, while the 1st stops on the rotational trajectory of the fork watt tooth top for entering escape wheel.The tooth top of escape wheel stops with the 1st as a result, The rotation of only fork watt engaging, escape wheel stops.Later, a series of above-mentioned cycles are repeated.

Patent document 1：Japanese Unexamined Patent Publication 2008-268209 bulletins

But in the escapement of above-mentioned previous indirect stroke type, due to the 1st escapement lever have the 1st stop fork watt, 2nd stops fork watt and the 1st impulse pallet, therefore along with the rotation of the 1st escapement lever, which can be integrally into action Make.Accordingly, it is difficult to for for making the stopping that escape wheel stops pitch watt (the 1st, which stops fork watt and the 2nd, stops fork watt) and for escapement It takes turns the impulse pallet (the 1st impulse pallet) of collision and most suitable layout is respectively configured based on respective design philosophy.

Hereinafter, being described in detail.

Due to keeping the effect that escape wheel stops different from the effect of impact being subject to from escape wheel, in design escapement On the basis of, also require with can effectively act as the most suitable layout of respective effect close in the state of be respectively configured Stop fork watt and impulse pallet.

The most suitable layout for stopping fork watt is following layout：By the configuration of the center of rotation of escapement lever as close to The position of the tooth top of outer diameter, that is, escape wheel of escape wheel.

It is with state and tooth top with defined angle in general, when stopping fork watt engages with the tooth top of escape wheel Contact surface engaging.This is to ensure that certain frictional force, realization will not phases between the contact surface of tooth top in stopping fork watt Engaging for the stabilization of contact surface sliding.

Since escapement lever is provided with angle, make stopping fork watt with the rotation of escapement lever and from the tooth top of escape wheel When disengaging, escape wheel can be made instantaneously to retreat (reverse rotation) to direction opposite to the direction of rotation.The retrogressing of escape wheel is In order to keep the engagement comprising the train including escape wheel more reliable or reliably obtain the required action of brake force of escapement lever.

In addition, stopping required until fork watt is detached from catch by being played from the stopping fork watt state engaged with the tooth top of escape wheel The rotational angle of vertical fork is referred to as operating angle (or releasing angle), and the angle that the tooth top of escape wheel retreats thus is referred to as receding angle.

As described above, by stopping draw caused by fork watt escape wheel is made to retreat in mechanical clock being necessary And important action, but then, receding angle is bigger, releases the energy needed for the stopping of escape wheel (that is, in order to make retrogressing Escape wheel returns to original direction of rotation and the energy that needs) it is bigger.

It releases the energy needed for the stopping of escape wheel more to increase, more easily cause as efficiency reduction or escapement error Deteriorate.Therefore, in the case where making stopping fork watt engage with the contact surface of the tooth top of escape wheel with defined angle, it is desirable that Escape wheel is set to retreat while so that receding angle is become smaller as much as possible.In the case of the known angle as defined in be provided with, escapement lever Center of rotation further away from the tooth top of escape wheel, which becomes bigger.

Therefore, as before, the most suitable layout of stopping fork watt is following layout：By turning for escapement lever Dynamic center configuration is in the position for the tooth top for being positioned as close to escape wheel.

In addition, the most suitable layout of impulse pallet is following layout：(rotation center of escape wheel and the tooth of escape wheel The distance between the node on top and impulse pallet) and (section of the center of rotation of escapement lever and the tooth top of escape wheel and impulse pallet Point the distance between) the ratio between be substantially inversely proportional with the operating angle of escape wheel and the ratio between the operating angle of impulse pallet.

In addition, the operating angle of escape wheel refers to, contacted until playing disengaging with impulse pallet from the tooth top of escape wheel needed for Escape wheel rotation angle, the operating angle of escapement lever refers to being contacted until playing disengaging with impulse pallet from the tooth top of escape wheel The rotational angle of required escapement lever.

In addition, the tooth top of escape wheel is same as the node that the node of impulse pallet is for example engaged with each other with teeth portion, it is equivalent to The intersection point of position and center line, wherein the position connection escape wheel tooth top and impulse pallet contact start when connect Contact point at the end of contact and contact, the center line connect the center of rotation of the rotation center and escapement lever of escape wheel.

In above-mentioned previous escapement, the 1st stopping being integrally assembled on the 1st escapement lever as before Fork watt, the 2nd stop fork watt and the 1st impulse pallet, thus be difficult only be conceived to stopping fork watt or impulse pallet and by the stopping Fork watt and impulse pallet are configured with above-mentioned most suitable layout respectively.

In addition, being respectively configured with respectively most suitable layout in order to which fork watt and impulse pallet will be stopped, it is also considered that for example As previously known Coaxial escapements (coaxial escapement), using stopping the 1st escape wheel and impact the 2nd The escape wheel for the double-layer structural that escape wheel is overlapped on the same axis, and change the diameter of the 1st escape wheel and the 2nd escape wheel.

But, in this case, since escape wheel is double-layer structural, other projects are produced：Escape wheel entirety Inertia becomes larger, and dynamic efficiency reduces.

In escapement lever body 91 be located at escapement fork shaft 90 with engage fork 92 between part at be provided with the 3rd fork watt a holding Watt maintaining part 93 is pitched towards 40 side opening of escape wheel in portion the 93, the 3rd.3rd fork watt maintaining part 93 keeps the 1st to stop using the opening Only fork watt 62.

1st, which stops fork watt 62, is maintained as compared with the 3rd fork watt maintaining part 93 to 40 side of escape wheel state outstanding.1st It is the escapement teeth 43 for escape wheel 42 to stop in the part outstanding of fork watt 62, the 2nd direction of rotation sides M2 of direction side Acting surface 43a engaging the 1st snap-latch surface 62a.In addition, the 1st stops fork watts 62 as so-called into watt functioning.

Make the 1st snap-latch surface 62a in addition, the 1st stopping fork watt 62 is installed into the state of with defined angle and catch The acting surface 43a engagings of vertical tooth 43.

The 4th fork watt maintaining part is provided at the peripheral end portion 91b of the 1st direction of rotation sides M1 in escapement lever body 91 94, the 4th pitches watt maintaining part 94 towards 40 side opening of escape wheel.4th fork watt maintaining part 94 keeps the 2nd stopping using the opening Fork watt 63.

2nd, which stops fork watt 63, is maintained as compared with the 4th fork watt maintaining part 94 to 40 side of escape wheel state outstanding.2nd It is the escapement teeth 43 for escape wheel 42 to stop in fork watt 63 parts outstanding, the 2nd direction of rotation sides M2 of direction side 2nd snap-latch surface 63a of acting surface 43a engagings.In addition, the 2nd stops fork watts 63 and goes out watt to function as so-called.

In addition, stopping fork watt 62 equally with the 1st, the 2nd, which stops fork watt 63, is installed into the state with defined angle Under so that the 2nd snap-latch surface 63a is engaged with the acting surface 43a of escapement teeth 43.

The stopping escapement lever 55 constituted by this method is as before, according to the rotation of the 1st impact escapement lever 51 And rotated around pivot center O5, the 1st impact escapement lever 51 be then according to the reciprocating rotary of balance spring mechanism 30 transfer into Row rotation.At this point, the 1st stop fork watt the 62 and the 2nd stop fork watt 63 according to the rotation for stopping escapement lever 55 and alternately repeatedly Into, exit the rotational trajectory R of escape wheel 40.

Thereby, it is possible to so that the acting surface 43a of the escapement teeth 43 of escape wheel 42 and the 1st is stopped the 1st snap-latch surface of fork watt 62 62a or the 2nd stops the 2nd snap-latch surface 63a engagings of fork watt 63.

Especially because the 1st stops the 62 and the 2nd stopping fork watt 63 of fork watt across pivot center O5 configurations, therefore stop the 1st When only fork watt 62 engages with escape wheel 42, the 2nd stops fork watt 63 is detached from from escape wheel 40, stops fork watt 62 from escapement the 1st When gear 42 is detached from, the 2nd stops fork watt 63 engages with escape wheel 40.

As described above, escapement fork chain 50 is by making the 1st impact escapement lever the 51, the 2nd impact escapement lever 52 and stopping escapement What fork 55 was constituted by being interconnected in a manner of connected in a column-shaped, and shifted in the following way：According to balance spring The reciprocating rotary of mechanism 30 transfers to make each escapement lever 51,52,55 each autorotations.That is, the 1st impact escapement lever 51 towards with balance spring The opposite direction rotation in the direction of rotation of mechanism 30, the 2nd impact escapement lever 52 and stops that escapement lever 55 is respectively facing and the 1st impacts The direction that the rotation direction of escapement lever 51 is opposite rotates.

In addition, the 2nd impact escapement lever 52 and stopping escapement lever 55 are equivalent to the escapement of the connecting end positioned at escapement fork chain 50 Fork.Wherein, restricted bar 85 is formed on the 2nd impact escapement lever 52, which stops fork watt the 62 and the 2nd the 1st and stop Pair a 2nd impact escapement lever 52 is positioned so that limitation escapement fork chain 50 when fork watt 63 engages with the escape wheel 42 of escape wheel 40 Whole displacement.

Limitation bar 85 is formed as protruding towards the direction separated with escape wheel 40 from the peripheral end portion 81b of escapement lever body 81.Limit Bar 85 processed limits the 2nd impact escapement lever 52 by being contacted with the spacer pin 86,87 for being configured at both sides across the limitation bar 85 It rotates and it is positioned.

A pair of of spacer pin 86,87 is fixed to for example protrude upward from bottom plate 11.One spacer pin 86 is configured to Positioned at the position for leaning on the 2nd direction of rotation sides M2 than limitation bar 85, another spacer pin 87 is configured to be located at and be leaned on than limitation bar 85 The position of the 1st direction of rotation sides M1.

Limitation bar 85 stops when fork watt 62 engages with the escape wheel 42 of escape wheel 40 and is located at the 2nd direction of rotation the 1st The spacer pin 86 of the sides M2 is contacted and is positioned to the 2nd impact escapement lever 52.In addition, limitation bar 85 the 2nd stop fork watts 63 with The escape wheel 42 of escape wheel 40 contacts with the spacer pin 87 positioned at the 1st direction of rotation sides M1 when engaging and impacts escapement to the 2nd Fork 52 is positioned.

(action of escapement)

Then, the action of the escapement 13 constituted as described above is illustrated.

In addition, under the action beginning state illustrated below, as shown in figure 4, the acting surface 43a of escapement teeth 43 stops with the 1st Only the 1st snap-latch surface 62a engagings of fork watt 62, and limit bar 85 and contacted with a spacer pin 86 and impact escapement lever 52 to the 2nd It is positioned.The rotation of escape wheel 40 stops as a result,.Also, pass through the free vibration of balance spring mechanism 30 so that impulse pallet 38 movements clockwise and the inside for entering escapement prong 74.

To moving with the escapement 13 of the reciprocating rotary of balance spring mechanism 30 the state since such action It illustrates in order.

When balance spring mechanism 30 is further by the rotating energy (power) for being stored in balance spring from state shown in Fig. 4 When rotating clockwise, traveling side in the inner surface of impulse pallet 38 and escapement prong 74, that the impulse pallet 38 is leaned on than impulse pallet 38 Engage to the inner surface contact of 73 side of plug of side, and pressing escapement prong 74 clockwise.Power from balance spring as a result, It is transmitted to the 1st impact escapement lever 51 via impulse pallet 38.

In addition, when escapement prong 74 engages with impulse pallet 38, safety disk 37 does not contact with each other with safety finger 75, therefore energy It is enough that the dynamic high efficiency from balance spring mechanism 30 is transferred to the 1st impact escapement lever 51.

As a result, as shown in fig. 7, impacting escapement lever 52 with the 1st impact escapement lever the 51, the 2nd and stopping the difference of escapement lever 55 The mode of rotation makes the entirety of escapement fork chain 50 be displaced.

That is, the 1st impact escapement lever 51 is rotated counterclockwise centered on pivot center O3, the 2nd impact escapement lever 52 is to rotate It is rotated clockwise centered on axes O 4, stops escapement lever 55 and rotated clockwise centered on pivot center O5.

By making the 2nd impact escapement lever 52 be rotated, limitation bar 85 leaves from a spacer pin 86.In addition, by making Stop escapement lever 55 to be rotated, the 1st stops fork watts 62 in a manner of sliding on the acting surface 43a in escapement teeth 43 towards from catching The direction (from the direction that the rotational trajectory R of escape wheel 40 is exited) that vertical wheel 40 is detached from is mobile.

Also, as shown in figure 8, slightly separated with the rotational trajectory R of escape wheel 40 by making the 1st stopping fork watt 62 be moved to Position, the 1st stopping fork watts 62 can be made to be detached from from escapement teeth 43, to release the 1st stopping fork watt 62 and escapement teeth 43 Engaging.Thereby, it is possible to release the stopping of escape wheel 40.

In addition, when releasing escapement teeth 43 with the engaging of the 1st stopping fork watt 62, since the 1st stopping fork watt 62 carries angle, Therefore as shown in fig. 7, escape wheel 40 is not to original direction of rotation i.e. the 1st direction of rotation M1 (clockwise) but is revolved to the 2nd Turning direction M2 (counterclockwise) moments retreats.After it have passed through the retrogressing of the moment, escape wheel 40 passes through via face side train 12 transmit the power come and restart to rotate to the 1st direction of rotation M1 as shown in Figure 8.

In this way, by making 40 moment of escape wheel retreat, the engagement of face side train 12 can be more reliably carried out, can be made Face side train 12 is stablized and is acted with high reliability.

In addition, as shown in Figure 7 and Figure 8, making 62 direction of the 1st stopping fork watt from escapement by stopping the rotation of escapement lever 55 When the direction movement that wheel 40 is detached from, the 1st impulse pallet 60 is entered by the rotation counterclockwise of the 1st impact escapement lever 51 and is caught In the rotational trajectory R of vertical wheel 40.

But since escape wheel 40 is moment retreats ground, to the 2nd rotation side due to the 1st stops fork watts 62 as described above It is rotated to M2, therefore descends escapement teeth 43 still not stop fork watt 62 with the 1st at this stage and contact.

Then, when the escape wheel of retrogressing 40 starts again at as shown in Figure 8 to be rotated towards the 1st direction of rotation M1, Later, as shown in figure 9, the 1st impulse pallet 60 of the acting surface 43a of escapement teeth 43 and the rotational trajectory R for entering escape wheel 40 The 1st shock surface 60a contact (collision).

Thereby, it is possible to which the rotary force of escape wheel 40 is transferred to the 1st impact escapement lever 51, in the inner surface of escapement prong 74 , than impulse pallet 38 by the side opposite with the direction of travel of the impulse pallet 38 73 side of plug inner surface and impulse pallet 38 connect It touches and engages.Power therefore, it is possible to will be transmitted to escape wheel 40 is indirectly transferred to balance wheel trip via the 1st impact escapement lever 51 Silk mechanism 30, and the 1st impact escapement lever 51 can be made persistently to be rotated in a manner of following impulse pallet 38.

In this way, being indirectly transferred to balance wheel trip via the 1st impact escapement lever 51 by the power that will be transmitted to escape wheel 40 Silk mechanism 30 can supplement rotating energy to balance spring mechanism 30.

As described above, when escapement teeth 43 and the 1st impulse pallet 60 contact, escapement teeth 43 is with sliding on the 1st shock surface 60a Dynamic mode is rotated towards the 1st direction of rotation M1, and the 1st impulse pallet 60 with the rotation of the 1st impact escapement lever 51 and by Gradually towards mobile from the direction (from the direction that the rotational trajectory R of escape wheel 40 is exited) that escape wheel 40 is detached from.

Then as shown in Figure 10, slightly separated with the rotational trajectory R of escape wheel 40 by making the 1st impulse pallet 60 be moved to Position, terminate indirect stroke to above-mentioned balance spring mechanism 30.

In addition, making the 1st impulse pallet 60 towards from the side that escape wheel 40 is detached from the rotation by the 1st impact escapement lever 51 To when movement, as shown in Figure 10, the 2nd stops fork watt 63 enters escape wheel by stopping the clockwise rotation of escapement lever 55 In 40 rotational trajectory R.

Then, it is moved in the 1st impulse pallet 60 after the position separated with the rotational trajectory R of escape wheel 40, such as Figure 11 Shown, the acting surface 43a of escapement teeth 43 stops the 2nd card of fork watt 63 with the 2nd of the rotational trajectory R for entering escape wheel 40 the at once Conjunction face 63a is contacted.

At this point, limitation bar 85 is moved with the clockwise rotation of the 2nd impact escapement lever 52 towards another spacer pin 87 It is dynamic, but, do not contacted in this stage with another spacer pin 87 still.Therefore, stop fork watt 63 with the 2nd in escapement teeth 43 to contact In the state of, stop the impact impact escapement lever 52 of escapement lever 51 and the 2nd of escapement lever the 55, the 1st and imperceptibly rotates respectively.

Then, as shown in figure 12, when limiting bar 85 and another spacer pin 87 contacts, the 2nd impact escapement lever 52 is limited System is further rotated and is positioned.Therefore, the whole displacement of escapement fork chain 50 is limited, becomes escapement teeth 43 and stops with the 2nd The only state of 63 engaging of fork watt.Escape wheel 40 stops rotating as a result,.

Then, impulse pallet 38 is detached from out of escapement prong 74, with the clockwise rotation of balance spring mechanism 30 with 1st impact escapement lever 51 detaches.Hereafter, balance spring mechanism 30 continues to rotate clockwise by inertia, and its rotating energy It is stored into balance spring.Then, when rotating energy is stored in balance spring completely, balance spring mechanism 30 stops clockwise rotation Turn, it is flashy it is static after, the rotating energy by being stored in balance spring starts to rotate counterclockwise.

As a result, as shown in figure 13, impulse pallet 38 towards the 1st with the rotation counterclockwise of balance spring mechanism 30 and to rush The close mode of escapement lever 51 is hit to start to move.

Then, as shown in figure 14, when impulse pallet 38 enters in the escapement prong 74 of the 1st impact escapement lever 51, disk The interior table of nail 38 and 73 side of plug in the inner surface of escapement prong 74, than impulse pallet 38 by the direction of travel side of the impulse pallet Face contacts and engages, and pressing escapement prong 74 counterclockwise.The power from balance spring is transferred to via impulse pallet 38 as a result, 1 impact escapement lever 51.

As a result, in such a way that the 1st impact escapement lever the 51, the 2nd impacts escapement lever 52 and stopping escapement lever 55 rotates respectively The entirety of escapement fork chain 50 is set to shift again.That is, the 1st impact escapement lever 51 is rotated clockwise centered on pivot center O3, the 2nd Impact escapement lever 52 is rotated counterclockwise centered on pivot center O4, and it is counterclockwise centered on pivot center O5 to stop escapement lever 55 Rotation.

By making the 2nd impact escapement lever 52 be rotated, limitation bar 85 leaves from another spacer pin 87.In addition, passing through So that stopping escapement lever 55 is rotated, the 2nd stop fork watts 63 in a manner of being slided on the acting surface 43a in escapement teeth 43 towards from The direction (from the direction that the rotational trajectory R of escape wheel 40 is exited) that escape wheel 40 is detached from is mobile.Also, as shown in figure 15, pass through So that the 2nd stopping fork watt 63 is moved to the position slightly separated with the rotational trajectory R of escape wheel 40, the 2nd stopping fork watt 63 can be made It is detached from from escapement teeth 43, to release the 2nd stopping fork watt 63 and the engaging of escapement teeth 43.Thereby, it is possible to release escape wheel 40 Stopping.

In addition, same as the 1st stopping fork watt 62, the 2nd stops fork watt 63 with angle, therefore as shown in figure 14, escape wheel 40 to the 2nd direction of rotation M2 moments after retreating, by via face side train 12 transmit come power by it is as shown in figure 15 As restart to the 1st direction of rotation M1 rotate.

In addition, making 63 direction of the 2nd stopping fork watt from the direction that escape wheel 40 is detached from by stopping the rotation of escapement lever 55 When mobile, as shown in Figure 14 and Figure 15, the 2nd impulse pallet 61 is entered by the rotation counterclockwise of the 2nd impact escapement lever 52 Into the rotational trajectory R of escape wheel 40.

But due to escape wheel 40 as described above by the 2nd stops fork watts 63 moment retreat after to the 2nd rotation side It is rotated to M2, therefore descends escapement teeth 43 still not stop fork watt 63 with the 2nd at this stage and contact.

Also, as shown in figure 16, when the escape wheel 40 of retrogressing restarts to rotate towards the 1st direction of rotation M1, escapement The acting surface 43a of tooth 43 is contacted with the 2nd shock surface 61a of the 2nd impulse pallet 61 for the rotational trajectory R for entering escape wheel 40 (collision).

Thereby, it is possible to which the rotary force of escape wheel 40 is transferred to the 1st impact escapement lever 51 via the 2nd impact escapement lever 52, 73 side of plug in the inner surface of escapement prong 74, that the side opposite with the direction of travel of the impulse pallet 38 is leaned on than impulse pallet 38 Inner surface contact and engage with impulse pallet 38.Therefore, it is possible to will be transmitted to the power of escape wheel 40 via the 2nd impact escapement lever 52 and the 1st impact escapement lever 51 is indirectly transferred to balance spring mechanism 30, and the 1st impact escapement lever 51 can be made to follow The mode of impulse pallet 38 persistently rotates.

In this way, being impacted between escapement lever 51 via the 2nd impact escapement lever 52 and the 1st by the power that will be transmitted to escape wheel 40 Ground connection is transferred to balance spring mechanism 30, can supplement rotating energy to balance spring mechanism 30.

As described above, when escapement teeth 43 and the 2nd impulse pallet 61 contact, escapement teeth 43 is with sliding on the 2nd shock surface 61a Dynamic mode is rotated towards the 1st direction of rotation M1, and the 2nd impulse pallet 61 with the rotation of the 2nd impact escapement lever 52 and by Gradually towards mobile from the direction (from the direction that the rotational trajectory R of escape wheel 40 is exited) that escape wheel 40 is detached from.

Also, as shown in figure 17, slightly divided with the rotational trajectory R of escape wheel 40 by making the 2nd impulse pallet 61 be moved to The indirect stroke to above-mentioned balance spring mechanism 30 is terminated in the position opened.

In addition, making the 2nd impulse pallet 61 towards from the side that escape wheel 40 is detached from the rotation by the 2nd impact escapement lever 52 To when movement, as shown in figure 17, the 1st stops fork watt 62 enters escape wheel by stopping the rotation counterclockwise of escapement lever 55 In 40 rotational trajectory R.

Then, it is moved in the 2nd impulse pallet 61 after the position separated with the rotational trajectory R of escape wheel 40, such as Figure 18 Shown, the acting surface 43a of escapement teeth 43 stops the 1st of fork watt 62 with the 1st in the rotational trajectory R for entering escape wheel 40 at once Snap-latch surface 62a contacts.

At this point, limitation bar 85 is moved with the rotation counterclockwise of the 2nd impact escapement lever 52 towards a spacer pin 86, But, it is not contacted in this stage with a spacer pin 86 still.

Therefore, in the state that escapement teeth 43 and the 1st stops 62 contact of fork watt, stop escapement lever the 55, the 1st and impact escapement lever 51 and the 2nd impact escapement lever 52 imperceptibly rotates respectively.Then, as shown in figure 19, when limitation bar 85 and a spacer pin 86 When contact, the 2nd impact escapement lever 52 is positioned by the further rotation of limitation.Therefore, it is whole to limit escapement fork chain 50 Displacement, become escapement teeth 43 and the 1st stop fork watt 62 states engaged.Escape wheel 40 stops rotating as a result,.

Then, as the reciprocating rotary of balance spring mechanism 30 transfers repeatedly above-mentioned action, to make escapement 13 repeatedly Ground carries out escapement teeth 43 and stops engaging/disengaging that fork watt the 62 and the 2nd stops fork watt 63 with the 1st, and utilizes escapement teeth 43 and the 1st Impulse pallet 60 carrys out the indirect transmission into action edge to balance spring mechanism 30 with the contact of the 2nd impulse pallet 61.

It is and straight to balance spring mechanism 30 therefore, it is possible to be acted as the escapement 13 of so-called indirect stroke type The case where connecing passing power is compared, it can be ensured that the transmission of stable action and power.

In particular according to the escapement 13 of present embodiment, there is impact in a common escapement lever over-assemble with previous Fork watt is different with the escapement for stopping fork watt, and the 1st impact escapement lever 51 and the 2nd impacts escapement lever 52 and is respectively provided with the 1st impact fork Watt the 60, the 2nd impulse pallet 61, stops escapement lever 55 and has the 1st to stop fork watt the 62 and the 2nd stopping fork watt 63.

Therefore, it is possible to respectively with less restriction freely design configurations impact escapement lever unit 53 (the 1st impact escapement lever 51 and the 2nd impact escapement lever 52) relative to escape wheel 40 relative position and stop escapement lever unit 56 and (stop escapement lever 55) relative position relative to escape wheel 40, so as to be caught with impacting and stopping respectively most suitable layout to configure impact Vertical fork unit 53 and stopping escapement lever unit 56.

The stopping escapement lever 55 of present embodiment is configured based on following such design philosophy.

Figure 20 shows the rotation center (i.e. rotation axis O2) of escape wheel 40, stops the center of rotation of escapement lever 55 (i.e. Pivot center O5) and the receding angle of escape wheel 40 between relationship.

In addition, the diagram of escape wheel 40 is omitted in fig. 20, but to rotation rail that the tooth top of escapement teeth 43 is depicted Mark R is shown.Rotational trajectory R is corresponding with the outer diameter of escape wheel 40 as a result,.

In addition, in fig. 20, it is illustrated that configuring the center of rotation for stopping escapement lever 55 in the rotation rail with escape wheel 40 The case where position of mark R separation distance L1 and configuration are in the distance L2 remote with the rotational trajectory R splitting ratio distances L1 of escape wheel 40 Position the case where.

In the case of wherein arbitrary, the 1st to stop fork watt 62 be all with the rotation for stopping escapement lever 55 and in engaging position It sets and is moved between X1 and releasing position X2, wherein clamped position X1 is the 1st stopping fork watt 62 positions engaged with escapement teeth 43 It sets, releasing position X2 is the 1st to stop the position that fork watts 62 is moved to the rotational trajectory R of escape wheel 40 is separated and release and catch The position of the engaging of vertical tooth 43.

In addition, connection the 1st stop the 1st snap-latch surface 62a of fork watts 62 and stop the center of rotation of escapement lever 55 line segment and Angle between the normal of 1st snap-latch surface 62a is angle α 1.In addition, the 1st stopping fork watt 62 is moved to releasing from clamped position X1 The rotational angle of stopping escapement lever 55 needed for during the X2 of position is operating angle (or releasing angle) α 2.In addition, will be along with the 1st Stopping fork watt 62 is moved to releasing position X2, escape wheel 40 retrogressing angle from clamped position X1 and is referred to as receding angle α 3.

In the case where operating angle α 2 is fixed as defined value according to above-mentioned condition, to stopping the rotation of escapement lever 55 What kind of the distance between center and the rotational trajectory R of escape wheel 40 can bring influence to illustrate to receding angle α 3.

As shown in figure 20, the rotational trajectory R separation distance L2's for the center of rotation and escape wheel 40 for stopping escapement lever 55 State and the center of rotation of stopping escapement lever 55 make stopping catch in the state of the rotational trajectory R separation distance L1 of escape wheel 40 Vertical fork 55 is rotated according to identical operating angle α 2 respectively, in this case, the receding angle α 3 when distance L1 can be made to be less than Receding angle α 3 when distance L2.That is, in the case where the center of rotation for stopping escapement lever 55 is relatively close away from rotational trajectory R, can make 3 smallers of receding angle α.

It therefore, can by making the center of rotation of stopping escapement lever 55 close to the rotational trajectory R of escape wheel 40 So that the receding angle of escape wheel 40 is become smaller, enables to release the energy needed for the stopping of escape wheel 40 (that is, in order to make catching for retrogressing Vertical wheel 40 returns to original direction of rotation and the energy that needs) become smaller.

In addition, in fig. 20, being conceived to the 1st stopping fork watt 62 and being illustrated, but for the 2nd stops fork watt 63 It is same.Therefore, make the center of rotation of stopping escapement lever 55 close to rotational trajectory R (the i.e. escapements of escape wheel 40 as much as possible The outer diameter of wheel 40) it is the most suitable layout most for stopping.

According to the present embodiment, due to can with for stopping it is most suitable layout come configure stop escapement lever 55, Therefore it enables to release the energy needed for the stopping of escape wheel 40 and becomes smaller and improve the transmission efficiency of power, and can reduce Action error.

In addition, can also the operating angle for stopping escapement lever 55 be designed as most suitable angle etc., it is easier to improve power Transmission efficiency.

In addition, it is based on following such design that the 1st impact escapement lever 51 and the 2nd of present embodiment, which impacts escapement lever 52, Thought and configure.

Figure 21 is the figure for showing the relationship when escapement teeth 43 of escape wheel 40 and the 1st impulse pallet 60 contact.In addition, scheming In 21, the tooth top of escapement teeth 43 and the 1st impulse pallet 60 are illustrated with approaching the case where state contacts that line contacts.

Operating angle α 4 is that the escapement needed for playing until contact terminates is contacted since escapement teeth 43 and the 1st impulse pallet 60 The rotational angle of wheel 40, operating angle α 4 are, for example, to be determined by the number of teeth of escape wheel 40.Also, operating angle α 5 is from escapement Tooth 43 starts to contact the rotational angle of the 1st impact escapement lever 51 needed for playing until contact terminates with the 1st impulse pallet 60, should Operating angle α 5 is the operating angle α 4 according to escape wheel 40 and determines.

Power is being efficiently transfer to the 1st punching from escape wheel 40 with the contact of the 1st impulse pallet 60 by escapement teeth 43 When hitting fork watts 60, for example, with teeth portion is mutual engage when node again it is preferred to escapement teeth 43 and the 1st impulse pallet 60 section Passing power at point P0.

In addition, node P0 is equivalent in the position of connection contact point P1 and contact point P2 and the rotation of connection escape wheel 40 The intersection point of the center line of the center of rotation (i.e. pivot center O3) of the heart (i.e. rotation axis O2) and the 1st impact escapement lever 51, wherein Contact point when contact point P1 is escapement teeth 43 and the 1st impulse pallet 60 beginning contact start, contact point P2 are contact knots Contact point when beam.

Also, in the case where considering the passing power at node P0, to determine the ratio of distance L3 and distance L4, In, distance L3 is the distance between rotation center and node P0 of escape wheel 40, and distance L4 is the 1st impact escapement lever 51 The distance between center of rotation and node P0.

In this case, the distance between the rotation center of escape wheel 40 and node P0 L3 and the 1st impacts escapement lever 51 The ratio of the distance between center of rotation and node P0 L4 impact the work of escapement lever 51 with the operating angle α 4 and the 1st of escape wheel 40 The ratio of angle α 5 is substantially inversely proportional.That is, as the (relationship of L3/L4) ≒ (5/ α 4 of α) is substantially met.

Therefore, such design is the most suitable layout for impact.In addition, this point is in the 2nd impulse pallet 61 It is impacted with the 2nd also the same in escapement lever 52.

Therefore, according to the present embodiment, due to can with for impact it is most suitable layout be respectively configured the 1st impact Escapement lever 51 and the 2nd impacts escapement lever 52, therefore the power that arbitrary impact escapement lever can will be transmitted to escape wheel 40 is high It is transferred to balance spring mechanism 30 to effect.In addition, the 1st impact escapement lever 51 and the 2nd can also be impacted to the work of escapement lever 52 Angle is designed as most suitable angle etc., it is easier to improve the transmission efficiency of power.

As described above, escapement 13 according to the present embodiment, can be to impacting and stopping is optimized and set Meter, can become power transmission efficiency is excellent and escapement that action error is small.

In addition, since the 1st impulse pallet 60 and the 2nd impulse pallet 61 are contacted with the acting surface 43a of escapement teeth 43, the 1st stops Only the 62 and the 2nd stopping fork watt 63 of fork watt engages with the acting surface 43a of escapement teeth 43, therefore escape wheel 40 can be made to become single layer structure It makes.Therefore, it is possible to inhibit the inertia of escape wheel 40 to become larger, the transmission efficiency of power thus can be also improved.

In addition, engaging with the 62 or the 2nd stopping fork watt 63 of the 1st stopping fork watt in escapement teeth 43 and the rotation of escape wheel 40 being made to stop In the case of only, i.e., in the case where impulse pallet 38 is detached from from escapement prong 74 and makes 30 free vibration of balance spring mechanism, limit Bar 85 processed and any one limit pin contacts in a pair of of spacer pin 86,87.Thereby, it is possible to the connection positioned at escapement lever chain 50 The 2nd impact escapement lever 52 at end is positioned, so as to limit the whole displacement of escapement fork chain 50.

Thus, for example can press down if even if receiving certain interference during 30 free vibration of balance spring mechanism The loosening or vibration of escapement fork chain 50 processed.Thereby, it is possible to so that escapement 13 is steadily acted.

In addition, movement 10 according to the present embodiment and clock and watch 1, due to having, dynamic transmission efficiency is excellent and action misses The small above-mentioned escapement 13 of difference, therefore as moment error small high performance movement and clock and watch.
