The anti-130 pairs of anti-stage clips 137 that shake of pedestal that shake, the anti-parts integral body such as endstone 110 and the anti-hole jewel bearing frame 120 that shakes of shaking keep.In more detail, anti-137 pairs of the stage clips of shaking are anti-, and shake endstone 110 and the anti-hole jewel bearing frame 120 that shakes keeps and absorbs impulsive force to hair-spring balance 103, and the endstone 110 when helping to be subject to impacting and hole jewel bearing frame 120 move (displacement) and to the direction recovery of original position.The power of bearing of trend (axially) A1, the A2 of the central axis C of the balance staff 140 of the anti-endstone 110 opposing hair-spring balances 103 that shake and support balance staff 140.Anti-shake hole jewel bearing frame 120 by stage clip 137 elasticity press on anti-shake pedestal 130 and when being subject to impacting etc. with respect to the movable movable frame of the anti-pedestal that shakes, this anti-hole jewel bearing frame 120 that shakes will be subject to radially that the hole jewel bearing 117 of the power of B is accommodated in inside and it is supported.
This anti-Bearning mechanism 101 that shakes is at the minor diameter tenon 141F of section, the 141R at the two ends of the balance staff 140 of the hair-spring balance 103 of mechanical clock 102 supporting balance staff 140.Below, about anti-Bearning mechanism 101F and 101R and their parts or the key element of shaking, represent at the back of same label additional letter F or R.When both are not distinguished or when general designation, omit alphabetical F and R.
The tenon bearing plane of endstone 110F, 110R or thrust bearing surface 111F, 111R are the plane.Be used for supporting be positioned at the bottom side of clock and watch 102 or hair-spring balance clamping plate side balance staff 140 the 141F of tenon section the anti-Bearning mechanism that shakes (being the hair-spring balance head bearing) 101F and be used for the anti-Bearning mechanism that shakes (the being the hair-spring balance lower bearing) 101R of the 141R of tenon section of balance staff 140 that supporting is positioned at the dial plate side of clock and watch 102 and be actually identical structure.
Here, hair-spring balance 103 is on the basis of up and down anti-shake bearing 101F, the 101R of the form of the anti-Bearning mechanism 101 that shakes, also possess balance staff 140, escapement 150 and hairspring 155, this hair-spring balance 103 is installed on hair-spring balance clamping plate 105 at the anti-bearing 101F place that shakes of bottom side.And the anti-bearing 101R that shakes of hair-spring balance clamping plate 105 and dial plate side is installed on respectively mainboard 108.Hairspring 155 possesses around the form of the vortex of the central axis C of balance staff 140, hairspring 155 is installed on hairspring inside stud 143 at interior all side ends of vortex, and be installed on hairspring stud (not shown) in the outer circumferential side end of vortex, adjust the effective length of this vortex (spring) by index lever (not shown).
The escape wheel speed regulator 104 that comprises hair-spring balance 103 also has escapement lever 106 and the escape wheel 107 that is supported by mainboard 108 on the basis of hair-spring balance 103.Escapement lever 106 engages by the impulse pallet 144 of jaw 161 with two disks, and by advancing watt and going out watt (not shown) and engage with the escape wheel teeth 162 of escape wheel 107.Escape wheel 107 is by pinion part 164 and No. four wheel 170 engagements.Power by clockwork spring (not shown) make No. four wheels 170 that escape wheel speed regulator 104 moves by escape wheel 107 with predetermined rotational speed intermittent rotary, the speed intermittent rotary of this escape wheel 107 to be limited by hair-spring balance 103.
In the clock and watch in the past 102 with the hair-spring balance in the past 103 that has possessed in the past anti-shake Bearning mechanism 101F, the 101R that as above, consist of, such as (a) of Figure 13 and (b) illustrating, be at hair-spring balance 103 in the situation of appropriate state PS0, clock and watch 102 carry out appropriate action.Namely, at the anti-Bearning mechanism 101F that shakes with bottom side and dial plate side, 101R and the 101F of this mechanism, the endstone 110F of 101R, 110R is configured to make endstone 110F, the plane tenon bearing plane 111F of 110R, 111R is vertical with respect to the central axis C of balance staff 140, and in the situation that in fact central axis C of balance staff 140 does not tilt, no matter take the anti-Bearning mechanism 101F that shakes of bottom side be positioned at the dial plate side the anti-Bearning mechanism 101R that shakes the top keep flat posture PP1, still the upset of top of taking the anti-Bearning mechanism 101R that shakes of dial plate side to be positioned at the anti-Bearning mechanism 101F that shakes of bottom side keeps flat posture PP2, balance staff 140 is all at position C0R, C0F and the anti-Bearning mechanism 101R that shakes that is positioned at dial plate side or the bottom side of its downside, the endstone 110R of 101F, the tenon bearing plane 111R of 110F, the 111F butt, and with this position C0R, rotate described position C0R centered by the C0F, C0F is the 141R of tenon section that is positioned at downside, the end face 145R of 141F, the in fact position by central axis C among the 145F.Therefore, regardless of posture PP1, the PP2 of clock and watch 102, in fact hair-spring balance 103 can both similarly move, can be with the poor bottom line that is suppressed to of posture.
But, possessed the anti-Bearning mechanism 101F that shakes in the past having, in the clock and watch in the past 102 of the hair-spring balance in the past 103 of 101R, when the direction on the anti-Bearning mechanism 101F that shakes that clock and watch 102 is configured to the bottom side is positioned at the anti-Bearning mechanism 101R that shakes of dial plate side is posture (hereinafter referred to as " keeping flat posture ") PP1, when being positioned at direction on the anti-Bearning mechanism 101F that shakes of bottom side and being posture (hereinafter referred to as " upset keeps flat posture ") PP2 with the anti-Bearning mechanism 101R that shakes that clock and watch 102 is configured to the dial plate side, the state of hair-spring balance 103 may produce different situations.
For example, such as (a) of Figure 14 with (b), endstone 110F in hair-spring balance clamping plate 105 sides or bottom side is installed under the state PS1 of hole jewel bearing frame 120F with the state that a little (for example about 1 degree) tilts by stage clip 137F, (a) as Figure 14 illustrate clock and watch 102 are configured to the bottom side the anti-Bearning mechanism 101F that shakes be positioned on the anti-Bearning mechanism 101R that shakes of dial plate side keep flat posture PP1 the time, with (b) as Figure 14 illustrate clock and watch 102 are configured to the dial plate side the anti-Bearning mechanism 101R that shakes when being positioned at upset on the anti-Bearning mechanism 101F that shakes of bottom side and keeping flat posture PP2, the state of hair-spring balance 103 becomes different situations.And the inclination for endstone 110F is typically, and results from the situation of hole jewel bearing frame 120F with respect to the anti-pedestal 130F inclination of shaking.
In the situation that is in the state PS1 that endstone 110F with hair-spring balance clamping plate 105 sides installed obliquely, (a) such as Figure 14 illustrate the anti-Bearning mechanism 101R that shakes of dial plate side be positioned at downside, and the endstone 110R of dial plate side bears the keeping flat among the posture PP1 of end face of the tenon 141R of balance staff 140 by its tenon bearing plane 111R, in fact the same with (a) and the situation (b) of Figure 13, balance staff 140 is at the tenon bearing plane 111R butt of position C0R with the endstone 110R of the anti-Bearning mechanism 101R that shakes of the dial plate side that is positioned at its downside, and centered by the C0R of this position, rotate, described position C0R is the in fact position by central axis C of end face 145R that is arranged in the 141R of tenon section of downside.
Relative therewith, with clock and watch 102 upsets, (b) such as Figure 14 illustrate the anti-Bearning mechanism 101F that shakes of hair-spring balance clamping plate 105 sides (bottom side) be positioned at downside, and the endstone 110F of hair-spring balance clamping plate 105 sides bears by its tenon bearing plane 111F among the posture PP2 of end face of tenon 141F of balance staff 140, different from the situation of Figure 13 (a) and situation (b) and Figure 14 (a), balance staff 140 leaves central axis C, and at the tenon bearing plane 111F butt of endstone 110F of ora terminalis CaF with the anti-Bearning mechanism 101F that shakes of hair-spring balance clamping plate 105 sides that are positioned at its downside, described ora terminalis CaF is the ora terminalis that is arranged in the consistent side of the vergence direction with endstone 110 of end face 145F of the 141F of tenon section of downside.Therefore, the rotation center CaF of balance staff 140 is different from the central axis C of this balance staff 140, the rotation center CaF of balance staff 140 leaves the size that △ pr(is equivalent to the radius of tenon section 141 from this central axis C, about several 10 μ m) some CaF(Ca), turning axle and unstable.
Therefore, in the situation that is in this state PS1, clock and watch 102 are when taking to keep flat posture PP1 and take upset when keeping flat posture PP2, and the action of hair-spring balance 103 is different, are difficult to avoid to produce step number poor of certain degree.
In addition, such as (a) of Figure 15 with (b) shown in (particularly (b) of Figure 15), for example keep flat among the posture PP2 in upset, under the situation PS2 that the central axis C of balance staff 140 tilts, also (a) with Figure 14 is the same with situation PS1 (b), balance staff 140 leaves from central axis C, and at the tenon bearing plane 111F butt of endstone 110F of ora terminalis CaF with the anti-Bearning mechanism 101F that shakes of hair-spring balance clamping plate 105 sides that are positioned at its downside, described ora terminalis CaF is the ora terminalis of end face 145F consistent with the vergence direction of central axis C balance staff 140 a side that is arranged in the 141F of tenon section of downside.Therefore, the rotation center CaF of balance staff 140 is different from the central axis C of this balance staff 140, the rotation center CaF of balance staff 140 leaves the size that △ pr(is equivalent to the radius of tenon section 141 from this central axis C, about several 10 μ m) some CaF(Ca), turning axle and unstable.
Even in the situation that is in this state PS2, clock and watch 102 are when taking to keep flat posture PP1 and take upset when keeping flat posture PP2, and the action of hair-spring balance 103 is also different, are difficult to avoid to produce step number poor of certain degree.
In addition, the inclination of the central axis C of balance staff 140 for example can result from the unbalanced situation of circumferential weight of escapement 150.And, strictly speaking, for example for the tightening action or unclamp action of the hairspring 155 of the form of volute spring the time, applied moment of torsion via hairspring inside stud 143 to balance staff 140, therewith correspondingly, the central axis C of balance staff 140 can tilt more or less, the more or less change of perhaps should tilting.
In addition, such as (a) of Figure 16 with (b), in the situation of the state PS3 that the end face 145F of the tenon 141F of hair-spring balance clamping plate 105 sides tilts with respect to the central axis C of balance staff 140, keep flat among the posture PP2 the outstanding ora terminalis CaF along with inclination among the end face 145F and the tenon bearing plane 111F butt of the endstone 110F of the anti-Bearning mechanism 101F that shakes of hair-spring balance clamping plate 105 sides that are positioned at its downside in upset.Therefore, the rotation center CaF of balance staff 140 is different from the central axis C of this balance staff 140, the rotation center CaF of balance staff 140 leaves the size that △ pr(is equivalent to the radius of tenon section 141 from this central axis C, about several 10 μ m) some CaF(Ca), turning axle and unstable.
Even in the situation that is in this state PS3, clock and watch 102 are when taking to keep flat posture PP1 and take upset when keeping flat posture PP2, and the action of hair-spring balance 103 is also different, are difficult to avoid to produce step number poor of certain degree.
On the other hand, following scheme has also been proposed: do not make end face 145F, the 145R of tenon 141F, the 141R of balance staff 140 become plane, make this end face or tenon 145F, 145R bend to convex but replace, avoid when clock and watch 102 are taked to keep flat posture PP1 and take to overturn producing the possibility raising of difference owing to various reasons as described above make step number when keeping flat posture PP2.
But, the diameter of tenon 141F, 141R is at most about 0.1mm usually, therefore be difficult to keep than the highland dimensional accuracy of the shape of convex curvature face, increase along with the deviation of the shape of convex curvature face if the long deviation of tenon is the deviation of the length of balance staff 140, the possibility that then produces difference in the shape that keeps flat posture PP1 and upset and keep flat hairspring 155 among the posture PP2 increases.Therefore, the hairspring 155 that originally should extend on the plane inside vortex shape ground vertical with respect to the central axis C of balance staff 140 for example is in when keeping flat posture PP1 or is in to overturn at clock and watch becomes funnel-form when keeping flat posture PP2 more or less, its spring performance change, poor possibility increases to be difficult to avoid producing step number.

Summary of the invention
The present invention finishes in view of the premises, its purpose is, a kind of anti-Bearning mechanism that shakes of hair-spring balance, the clock and watch that possess the hair-spring balance of this anti-Bearning mechanism that shakes and possess this anti-Bearning mechanism that shakes are provided, and the shake change of action of the hair-spring balance that Bearning mechanism can cause the change owing to the bearing state of balance staff of described hair-spring balance anti-is suppressed to bottom line.
In order to reach described purpose, the anti-Bearning mechanism that shakes of hair-spring balance of the present invention has: endstone, and it is as thrust bearing work; Hole jewel bearing, it is as transverse bearing work; The hole jewel bearing frame, it is used for taking in hole jewel bearing, and this hole jewel bearing is supported; The anti-pedestal that shakes, it is used for taking in this hole jewel bearing frame and this hole jewel bearing frame of supporting, and this anti-pedestal that shakes possesses the holding section in large diameter open end side; And stage clip, it is supported by the holding section of the anti-pedestal that shakes at outer circumferential side, and in interior all sides endstone flexibly is pressed into the hole jewel bearing frame and keeps this endstone, in the endstone with opposed by the end face of the axle of the anti-Bearning mechanism supporting of shaking and consisted of by convex surface with the surface of the end face butt of this axle, this convex surface is crooked in outwards outstanding mode.
In the anti-Bearning mechanism that shakes of hair-spring balance of the present invention, because " in the endstone with opposed by the end face of the axle of the anti-Bearning mechanism supporting of shaking and consisted of by convex surface with the surface of the end face butt of this axle; this convex surface is crooked in outwards outstanding mode ", therefore, even the endstone by hole jewel bearing frame and stage clip maintenance tilts, perhaps the central axis of axle (center of gravity line) tilts, the perhaps end slope of axle, with " in the endstone with opposed by the end face of the axle of the anti-Bearning mechanism supporting of shaking and with the surface of the end face butt of this axle " be that the situation on " plane " is compared, follow the position of the swivel bearing section of these inclinations to be offset and be suppressed to bottom line.Therefore, for example the posture of clock and watch can also be suppressed to bottom line to the impact of step number.In addition, because " surface of endstone (tenon bearing plane) is the convex surface with outwards outstanding mode bending ", therefore can be in fact with some butts and supporting with respect to the end face of the axle that should be rotated supporting, the rotation of axle is stable easily thus.In addition, in the case, should can be formed planely by the shake end (tenon) of the end face of end of axle (balance staff) of Bearning mechanism supporting or this end (tenon section) of hair-spring balance anti-, therefore the deviation of the length of axle (balance staff) can be suppressed to bottom line.
In the anti-Bearning mechanism that shakes of hair-spring balance of the present invention, the convex surface that is typically endstone is made of the part of sphere.
In the case, correctly or accurately form easily the convex surface of endstone.And convex surface then also can be other shape if the need arises as long as be seen as in a broad sense the ellipse of revolution dignity that comprises sphere.Convex surface so long as protrude to extroversion, crooked shape smoothly, then convex surface also can not have rotational symmetry.But, in order to be suppressed to bottom line for the impact (change of action) of the action of the hair-spring balance as step number the fluctuation zone of the bearing state of the balance staff as the inclination of endstone, preferred described convex surface is spherical of part (part of sphere).
In the anti-Bearning mechanism that shakes of hair-spring balance of the present invention, be typically: endstone has the such shape of convex lens, the hole jewel bearing framework becomes the wide diameter portion that possesses cylindrical portion and lean on the open end side of this cylindrical portion, and at the position of this wide diameter portion supporting endstone, stage clip constitutes: supported by the holding section of the anti-pedestal that shakes at outer circumferential side, and in interior all sides the position that endstone flexibly is pressed into the wide diameter portion of hole jewel bearing frame is come this endstone is kept.
In the case, even the thickness with the anti-Bearning mechanism that shakes be suppressed under the MIN state and with the end face of the opposed axle of this Bearning mechanism be the plane, the change of the action of the hair-spring balance that still change by the bearing state of balance staff can be caused is suppressed to bottom line, can also by as keep flat the change that posture and upset keep flat the poor action that causes of posture of posture and be suppressed to bottom line.
In the other exemplary of the anti-Bearning mechanism that shakes of hair-spring balance of the present invention, endstone is made of spheroid.
In the case, endstone forms with high dimensional accuracy, also the action change of hair-spring balance can be suppressed to bottom line.
In addition, in the situation of described other exemplary, spherical endstone is being configured in the mode of hole jewel bearing butt in the cylindrical region of hole jewel bearing frame, stage clip constitutes: supported by the holding section of the anti-pedestal that shakes at outer circumferential side, and in the cylindrical region of hole jewel bearing frame, endstone is pressed into the opposed end face of hole jewel bearing in interior all sides, thus, via hole jewel bearing endstone flexibly is pressed into the hole jewel bearing frame to keep.
In the case, can will owing to endstone is that the increase of the thickness that causes of the form of spheroid (ball) is suppressed under the MIN state, enjoy the advantage that endstone is spheroid (ball).
In the anti-Bearning mechanism that shakes of hair-spring balance of the present invention, be typically, the position of supporting for the tenon bearing plane to endstone in the hole jewel bearing frame is circular cone shape.
In the case, the change of the action of hair-spring balance can be suppressed to bottom line.Also can be with the spherical circular cone shape that replaces.
In order to achieve the above object, hair-spring balance of the present invention has the anti-Bearning mechanism that shakes as described above.
In hair-spring balance of the present invention, consisted of by balance staff by the axle of the anti-Bearning mechanism supporting of shaking, the end face that is positioned at the both ends of balance staff and the diameter tenon section less than the main part of this balance staff is actually plane.
In the case, the length of balance staff can be obtained with high dimensional accuracy, consequently, the change that keeps flat posture or upset owing to clock and watch and keep flat the step number that posture causes bottom line can be suppressed to.
In order to achieve the above object, clock and watch of the present invention have anti-Bearning mechanism or the hair-spring balance as described above of shaking as described above.

Hole jewel bearing frame 20 has: minor diameter cylindrical portion 21, the tabular end flange shape of large diameter tubular section 22, the ring-type section 23 as wide diameter portion, circular cone shape end flange shape section 24, flange connector shape section 25 and tilt facial 26a and 26b, wherein, described circular cone shape end flange shape section 24 possesses the end axial region accommodation hole 24a chimeric with end axial region 42 play of balance staff 40.The inner peripheral surface 21a of minor diameter cylindrical portion 21 is cylindric, at these minor diameter cylindrical portion 21 chimeric hole jewel bearings 17.The tabular end flange shape of ring-type section 23 is formed at an end of minor diameter cylindrical portion 21, circular cone shape end flange shape section 24 is connected with the radially inner side end of the tabular end flange shape of ring-type section 23 by its larger diameter side end, and extends to the axial region accommodation hole end, end of regulation end axial region accommodation hole 24a.The inner side end 23a of the tabular end flange shape of ring-type section 23 is plane, and supports this hole jewel bearing 17 with the end face 17b butt of the hole jewel bearing 17 that is embedded in minor diameter cylindrical portion 21.The diameter of large diameter tubular section 22 is larger than the diameter of minor diameter cylindrical portion 21, and large diameter tubular section 22 is connected with the other end of minor diameter cylindrical portion 21 via flange connector shape section 25 in that one is distolateral.Inside surface 25a as the flange connector shape section 25 of the open end of cylindrical portion 21 is circular cone shape, its with as the Outboard Sections butt of the spherical end face 11 of part tenon bearing plane 11, that convex lens are such of endstone 10, come by the spherical end face 11 supporting endstones 10 of this part.End axial region accommodation hole 24a is slightly larger than the diameter of the end axial region 42 of balance staff 40.Tilt facial 26a, 26b is respectively the form of the outer peripheral face of the frustum of a cone, be typically, two tilt facial 26a, 26b with similarly and the mode of linearity ground arrangement dispose, part with the outer peripheral face that becomes the same imaginary frustum of a cone, during precalculated position in hole jewel bearing frame 20 being configured in the anti-pedestal 30 that shakes, inclination face 35a, the 35b butt of described inclination facial 26a, 26b and this anti-pedestal 30 that shakes.The facial 26a that tilts is formed at the outer peripheral face of circular cone shape end flange shape section 24, and the facial 26b that tilts is formed near the outer peripheral face of the end of the flange connector shape section 25 in the large diameter tubular section 22.
The anti-stage clip 37 that shakes is the shape as clover, it is by engaging with the radial inward holding section 36 of the anti-pedestal 30 that shakes from 38 outstanding holding section 38a, 38a, the 38a of major diameter section, and engage with the outside end face 12 of endstone 10 by the U word shape holding section 39,39,39 of extending to radially inner side, thereby this endstone 10 is pressed into the inside surface 25a of the flange connector shape section 25 of hole jewel bearing frame 20.Thus, via endstone 10 hole jewel bearing frame 20 is pressed into inclination facial 35a, the 35b of the anti-pedestal 30 that shakes at tilt facial 26a, 26b.And, as long as the anti-stage clip 37 that shakes can be pressed endstone 10, also can replace shape as clover for other shape.
Therefore, the anti-stage clip 37 that shakes flexibly keeps anti-endstone 10 and the anti-hole jewel bearing frame 20 and absorb the impulsive force that produces to the main body of hair-spring balance 3 of shaking of shaking, and endstone 10 and hole jewel bearing frame 20 when being subject to impacting can be moved and restore.The user clock and watch 2 of wrist-watch form are worn under the state of wrist; when because the rapid activity of user's wrist when causing axial impact to put on balance staff 40; by the axial force (impact) that acts on balance staff 40; endstone 10 is subject to power from the A direction of the end face (tenon) 45 of tenon 41 in tenon bearing plane 11, allows that the displacement of A direction and the impact-absorbing of endstone 10 comes tenon section 41 is protected.In addition; when since the rapid activity of user's wrist cause laterally (with respect to axial rectangular direction) thus impact put on balance staff 40 balance staffs 40 when being subject to power (impact) with respect to the rectangular direction of central axis C; the power of this direction acts on mortise 18 from tenon section 41; therefore; the elastic force of hole jewel bearing frame 20 opposing stage clips 37 and along the snap-latch surface displacement between inclined-plane 35a, the 35b of inclined-plane 26a, the 26b of this hole jewel bearing frame 20 and the anti-pedestal 30 that shakes, thus impact-absorbing is to protect tenon section 41.No matter in which kind of situation, when impacting when disappearing, always get back to original position by the power of stage clip.
Has the anti-Bearning mechanism 1F that shakes that has possessed an of the present invention preferred embodiment who as top, consists of, in the mechanical clock 2 of an of the present invention preferred embodiment of the hair-spring balance 3 of the of the present invention preferred embodiment of 1R, with reference to (a) of Fig. 4 and (b), (a) of Fig. 5 and (b) and Fig. 6 (a) and (b) is under various conditions, the anti-Bearning mechanism 1F that shakes that clock and watch 2 are configured to the bottom side be positioned at the situation of " keeping flat posture " P1 on the anti-Bearning mechanism 1R that shakes of dial plate side and the anti-Bearning mechanism 1R that shakes that clock and watch 2 are configured to the dial plate side is positioned at difference between the situation of " upset the keeps flat posture " P2 on the anti-Bearning mechanism 1F that shakes of bottom side have or not or the degree of difference is described in detail.
Be configured in fact to be in the situation of the rotational symmetric state of central axis C with respect to central axis C bearing plane 11F, the 11R vertical and the spherical calotte shape of the balance staff 40 of hair-spring balance 3 at endstone 10F, 10R, when clock and watch 2 take to keep flat posture P1 and take upset when keeping flat posture P2, the bearing state of the balance staff 40 of hair-spring balance 3 is practically identical, therefore, as in the past, in fact do not exist keeping flat the difference that posture P1 and upset keep flat step number under the posture P2.And, in this hair-spring balance 3, tenon bearing plane 11F, the 11R of endstone 10F, 10R are the spherical calotte shape, thus this tenon bearing plane 11F, 11R with respect to end face 45F, the 45R of the 41F of tenon section, the 41R of balance staff 40 in fact with some butts, therefore, the rotation of balance staff 40 is stable easily.
Such as (a) of Fig. 4 with (b), endstone 10F in hair-spring balance clamping plate 5 sides or bottom side is installed under the state S1 of hole jewel bearing frame 20F with the state that a little (for example about 1 degree) tilts by stage clip 37F, strictly speaking, when clock and watch 2 taked upset to keep flat posture P2 when clock and watch 2 were taked to keep flat posture P1 (a) such as Fig. 4 illustrated and as (b) of Fig. 4 illustrates, the state of hair-spring balance 3 was for more or less there being some different situations.For the inclination of endstone 10F, occur in hole jewel bearing frame 20F in the situation that dip plane 26a, 26b tilt with respect to the anti-pedestal 30F that shakes with respect to dip plane 35a, the 35b skew of the anti-pedestal 30F that shakes thereby be typically.And, this situation (different with the state of hair-spring balance of taking to overturn when keeping flat posture when clock and watch are taked to keep flat posture) itself is the same when with (a) that contact Figure 14 and (b) clock and watch in the past 102 with the hair-spring balance in the past 103 that has possessed anti-shake Bearning mechanism 101F, 101R in the past being described, but is different with the degree of the difference of the state of the hair-spring balance when keeping flat posture that overturns in clock and watch 2 and in the past clock and watch 102 when keeping flat posture.
Namely, in clock and watch 2, in the situation that is in the state S1 that endstone 10F with hair-spring balance clamping plate 5 sides installed obliquely, at (a) such as Fig. 4 illustrating, the endstone 10R that the anti-Bearning mechanism 1R that shakes of dial plate side is arranged in downside and dial plate side bear by its tenon bearing plane 11R balance staff 40 tenon 41R end face 45R keep flat posture P1, balance staff 40 is at the tenon bearing plane 11R butt of position C0R with the spherical calotte shape of the endstone 10R of the anti-Bearning mechanism 1R that shakes of the dial plate side that is positioned at its downside, and centered by the C0R of this butt position, rotate around central axis C, described position C0R is the position of passing through central axis C of end face 45R that is arranged in the 41R of tenon section of downside, and the situation of this situation and Figure 14 (a) is practically identical.Namely, in this scope, can not occur owing to by stage clip 37F the endstone 10F of hair-spring balance clamping plate 5 sides or bottom side is installed on the impact that hole jewel bearing frame 20F produces with the state of a little (for example about 1 degree) inclination, the situation of this and Figure 14 (a) is practically identical.But strictly speaking, the tenon bearing plane 11R of endstone 10R bends to convex in these clock and watch 2, therefore, becomes reliably on the rotation center this point at the position C0R consistent with central axis C and there are differences with clock and watch 102.
On the other hand, with clock and watch 2 upsets, the endstone 10F that is arranged in downside and hair-spring balance clamping plate 5 sides at (b) such as Fig. 4 anti-Bearning mechanism 1F that shake illustrating, hair-spring balance clamping plate 5 sides (bottom side) bears the tenon 41F of balance staff 40 by its tenon bearing plane 11F the upset of end face 45F keeps flat posture P2, even the profile of the tenon bearing plane 11F of central axis C near produces skew a little, the profile of tenon bearing plane 11F is also as before much the same with the inclination that produces about 1 degree being shown in phantom line among (b) of Fig. 4.Especially, along with the roughly inclination of 1 degree of endstone 10F, the position CaV that the tangent line among the tenon bearing plane 11F is vertical with respect to central axis C is roughly consistent with the position that central axis C intersects with bearing plane 11F.Namely, when owing to hole jewel bearing frame 20F with respect to the skew (face 26a, 26b are with respect to the skew of face 35a, 35b) of the anti-pedestal 30 that shakes when producing the inclination of endstone 10F, even the rotation of tenon bearing plane 11F and 1 degree is correspondingly at 1 degree that roughly rotates in a circumferential direction, also can make the direction of the tangent plane of the position C0F that intersects with central axis C among the tenon bearing plane 11F keep roughly fixing, therefore, consequently, the position C0F skew of intersecting from bearing plane 11F and central axis C hardly with respect to the vertical position CaV of central axis C of the tangent plane among the tenon bearing plane 11F.Therefore, balance staff 40 is the tenon bearing plane 11F butt with the spherical calotte shape of the endstone 10F of the anti-Bearning mechanism 1F that shakes of the dial plate side that is positioned at its downside at a CaV place, and centered by the CaV of this position, rotate around central axis C, described some CaV is near the point of the position of passing through central axis C of end face 45F that is arranged in the 41F of tenon section of downside.And, even tenon bearing plane 11F along the circular cone shape inside surface 25a of the flange connector shape section 25 of hole jewel bearing frame 20F skew, situation also is identical.
Namely, in the mechanical clock 2 with hair-spring balance 3, described hair-spring balance 3 possesses the anti-Bearning mechanism 1F that shakes, 1R, this anti-Bearning mechanism 1F that shakes, 1R possesses the spherical convex curvature tenon bearing plane 11F of part, 11R, such as (a) of Fig. 4 with (b), by stage clip 37F the endstone 10F of hair-spring balance clamping plate 5 sides or bottom side is being installed among the state S1 of hole jewel bearing frame 20F with the state that a little (for example about 1 degree) tilts, when the such clock and watch 2 shown in Fig. 4 (a) take to keep flat posture P1, when taking upset to keep flat posture P2 with the such clock and watch 2 shown in Fig. 4 (b), strictly speaking, the state of hair-spring balance 3 is more or less different situation, but in fact, even keep flat in the situation of posture P2 taking to overturn, the position of the end face 45F butt of the convex curvature tenon bearing plane 11F that the part of the anti-Bearning mechanism 1F that shakes is spherical and the 41F of tenon section of balance staff 40 also is positioned at the position CaV on the approximate centre axis C.Therefore, keep flat among the posture P2 keeping flat posture P1 and upset, in fact hair-spring balance 3 can equally move, and (a) of diversity ratio Figure 14 of step number and situation (b) are little a lot.
On the other hand, such as (a) of Fig. 5 with (b) shown in (particularly (b) of Fig. 5), keep flat among the posture P2 in upset, under the central axis C situation S2 that (for example about 0.2 degree) tilts a little of balance staff 40, the end face 45F of the 41F of tenon section of balance staff 40 is at the tenon bearing plane 11F butt of the position Cb that leaves a little from the central axis C of balance staff 40 with the endstone 10F of the anti-Bearning mechanism 1F that shakes of hair-spring balance clamping plate 5 sides that are positioned at its downside.Here, position Cb is equivalent to the tangent plane position (position that can consistent) parallel with the end face 45F of the 41F of tenon section of balance staff 40 of the tenon bearing plane 11F of endstone 10F, and described balance staff 40 has the central axis C of inclination.
Therefore, the rotation center Cb of balance staff 40 is different from the central axis C of this balance staff 40, the rotation center Cb of balance staff 40 is positioned at the part of leaving the radius of △ r(tenon section 41 from the position that this central axis C is passed through, about 10 μ m) the position, balance staff 40 rotates centered by a Cb.
In the situation that is in this state S2, when clock and watch 2 take to keep flat posture P1 and take upset when keeping flat posture P2, the action of hair-spring balance 3 is in fact different, is difficult to avoid producing the poor of small step number.But, the center Cb when keeping flat posture P2 of taking to overturn is about the part of radius of tenon section 41 of balance staff 40 from the skew of center C, in this, compare with the clock and watch in the past 102 of the skew (Figure 15 (b)) of the radius degree of the tenon section 41 that produces balance staff 40, can reduce significantly the difference that upset keeps flat posture P2 and keeps flat the step number between the posture P1.
In addition, the inclination of the central axis C of balance staff 40 has a variety of causes.That is, produce in the central axis C of balance staff 40 in the situation of tilt phenomenon, no matter the posture of clock and watch 2 how, is compared with clock and watch 102 in the past, can both reduce the worry that step number produces larger difference.As such example, the situation that for example have the weight of escapement 50 uneven, escapement 50 tilts.And strictly speaking, for example, when the vortex of hairspring 55 was tightened or unclamps, owing to act on the power of balance staff 40 from hairspring 55 via hairspring inside stud 43, the axle of the central axis C of balance staff 40 also may tilt more or less.Even under these circumstances, possess in this anti-Bearning mechanism 1 that shakes, 1 the hair-spring balance 3 at the two ends of balance staff 40, be that the situation on plane is different from tenon bearing plane 111 as hair-spring balance 103 in the past, tenon bearing plane 11 is spherical calotte, therefore, be not the lateral margin of end face 45 of the tenon section 41 of balance staff 40, but near the position of the central axis C in this end face 45 can with the position butt of the tangent plane of the corresponding inclination of tenon bearing plane 11.Therefore, the center of the rotation of balance staff 40 can be suppressed to bottom line from the degree of central axis C skew.
In addition, such as (a) of Fig. 6 with (b), under the state S3 that the end face 45F of the tenon 41F of hair-spring balance clamping plate 5 sides tilts with respect to the central axis C of balance staff 40, keep flat among the posture P2 in upset, the end face 45F that tilts is at the tenon bearing plane 11F of position Cd and endstone 10F butt, and this position Cd is the inclination position consistent with the inclination of end face 45F of tenon bearing plane 11F of endstone 10F of the anti-Bearning mechanism 1F that shakes of hair-spring balance clamping plate 5 sides.This position Cd is and position Cb shown in Figure 5 consistent position roughly.
Namely, even in the situation that is in this state S3, when clock and watch 2 take to keep flat posture P1 and take upset when keeping flat posture P2, the action of hair-spring balance 3 is also different, but its difference is the same with situation (b) with Fig. 5 (a), compare with the clock and watch in the past 102 that (b) illustrates with Figure 16 (a), can reduce significantly the difference that upset keeps flat posture P2 and keeps flat the step number between the posture P1.
Therefore, the rotation center Cd of balance staff 40 is different from the central axis C of this balance staff 40, and balance staff 40 is with the part of the radius that leaves about △ r(tenon section 41 from this central axis C, about 10 μ m) some Cd centered by rotate.
In addition, as above, in clock and watch 2, it is spherical that the bearing plane 11 of endstone 10 forms part, even therefore various inclinations etc. are arranged, rotation center is also very little from the side-play amount of the center C of balance staff 40 skew, therefore the change of the step number of the clock and watch 2 that caused by the posture that keeps flat posture P1 and upset and keep flat posture P2 etc. can be suppressed to bottom line.
In addition, in these clock and watch 2, forming the spherical part of part is tenon bearing plane 11F, the 11R of endstone 10, rather than the 41F of tenon section of balance staff 40, end face 45F, the 45R of 41R, and the diameter of this spherical calotte is larger, so the possibility that the length of balance staff 40 and other amount change significantly is also less.
Such as (a) of Fig. 7 and (b) and shown in Figure 8, endstone 10A is made of spheroid 13, replaces endstone to possess the spherical tenon bearing plane of part.At (a) that possess Fig. 7 with (b) and among the hair-spring balance 3A of the anti-bearing arrangement body 1A that shakes shown in Fig. 8, to with the same element annotation of the key element of the hair-spring balance 3 that possesses the anti-bearing arrangement body 1 that shakes shown in Fig. 1 to Fig. 3 same label, to the key element of corresponding but variant part in the end with alphabetical A.And, the letter " F " that is expressed as bottom side or hair-spring balance clamping plate side is being arranged and is being expressed as in the situation of letter " R " of dial plate side, in the front of this letter F, R with alphabetical A.
In the anti-bearing arrangement body 1A that shakes of hair-spring balance 3A, endstone 10A is made of spheroid 13, therefore improves easily the dimensional accuracy of endstone 10A.And, in the anti-bearing arrangement body 1A that shakes of hair-spring balance 3A, endstone 10A is made of spheroid 13, therefore the size of the thickness direction of clock and watch 2A increases, therefore anti-ly shake pedestal 30A except having axial length than the large 32A of the large diameter tubular section this point of the large diameter tubular section 32 of the anti-pedestal 30 that shakes, be actually same structure with the anti-pedestal 30 that shakes.
In addition, in the anti-bearing arrangement body 1A that shakes, endstone 10A is made of spheroid 13, the size of the thickness direction of clock and watch 2A increases, therefore, different from the situation of the anti-bearing arrangement body 1 that shakes, endstone 10A is not axially being supported by hole jewel bearing frame 20A, but is supported by hole jewel bearing 17A.Therefore, the end face 17dA of hole jewel bearing 17A becomes be used to spherical 14 the circular cone shape face that bears endstone 10A.Inboard with spherical facial 14 annular section of the circular cone shape end face 17dA butt of hole jewel bearing 17A among the endstone 10A becomes tenon bearing plane 11A.
In addition, stage clip 37A engages with the holding section 36 of the anti-pedestal 30A that shakes by outer circumferential side holding section 38a, 38a, 38a, area pressed 12A is come in U word shape holding section 39,39,39 by interior all sides, this zone 12A be arranged in spheroid 13 forms endstone 10A with tenon bearing plane 11A in the opposite side of diametric(al).
For hole jewel bearing frame 20A, as long as be conceived to outer circumferential surface section, it is exactly the structure roughly the same with hole jewel bearing frame 20, and described hole jewel bearing frame 20A has: the periphery minor diameter cylindrical portion 21A corresponding with minor diameter cylindrical portion 21, with the periphery large diameter tubular 22A of section corresponding to large diameter tubular section 22 and with they couple together with profile circular cone shape flange connector shape 25A of section corresponding to flange connector shape section 25 etc.But, different from endstone 10, in order to suppress thickness, endstone 10A is made of the spheroid 13 of minor diameter, thus endstone 10A be configured in the roughly the same tubular inner peripheral surface 27 of the tubular inner peripheral surface 21a of hole jewel bearing frame 20A in.And this tubular inner peripheral surface 27 is the inner peripheral surface of the periphery large diameter tubular 22A of section.
As shown in Figure 8, in the anti-bearing arrangement body 1A that shakes that as above consists of, the tenon section 41 of the balance staff 40 of hair-spring balance 3 is embedded in the mortise 18 of hole jewel bearing 17A, and be used as all surface bearings of this mortise 18 of transverse bearing work, the end face 45 of tenon section 41 is the form of spheroid 13, it bears facial 11A butt with tenon as the endstone 10A of thrust bearing work, and is born facial 11A supporting by this tenon.
Fig. 9 shows the degree of the position skew of the rotation center under various conditions in the hair-spring balance of Fig. 8 of the anti-Bearning mechanism that shakes with Fig. 7, and (a) of Fig. 9 shows the situation that balance staff and endstone are in the benchmark of predetermined state.In the case, the tenon section 41 of balance staff 40 is at the tenon bearing plane 11A of the endstone 10A of the position of its end face 45 C0 and spheroid 13 forms butt.This position is the position corresponding with the C0R of Fig. 4, and it is positioned on the central axis C of balance staff 40.
Fig. 9 (b) shows the situation that endstone is in the state of inclination, even the endstone 10A of spheroid 13 forms a little (for example about 1 degree) tilts, because endstone 10A is supported by the circular cone shape end face 17dA of hole jewel bearing 17 at the annular section 14 of spheroid 13, therefore, according to this rotation, butt position Cf between the end face 45 of the endstone 10A of spheroid 13 forms and the tenon section 41 of balance staff 40 is constant, in fact remains in position C0.Therefore, even endstone 10A tilts, no matter be in and keep flat posture P1 or upset keeps flat posture P2, in fact hair-spring balance 3A can both similarly move, and therefore posture can be suppressed to bottom line to the impact of step number.
Fig. 9 (c) shows the situation that balance staff is in the state of inclination, and along with the inclination of balance staff 40, the end face 45 of tenon section 41 tilts.But, in the hair-spring balance 3A that possesses this anti-Bearning mechanism 1A that shakes, the endstone 10A of the anti-Bearning mechanism 1A that shakes is made of the smaller spheroid 13 of diameter, therefore, the butt position only position C0 on the central axis C is offset a little, the inclination of tangent plane just changes significantly, therefore, with the end face 45 of the tenon section 41 of the balance staff 40 that has tilted a little just in time the position of butt for leaving a little the position Cg of central axis C.Consequently, the inclination of balance staff 40 can be suppressed to bottom line to the impact of the rotation of hair-spring balance 3A.
