Description
Technical field
The present invention relates to temperature compensating type hair-spring balance, movement and clock and watch.
Background technology
The hair-spring balance that governor as mechanical clock functions has：The balance staff extended along axis；It is fixed
In the balance wheel of balance staff；And balance spring.Balance staff and balance wheel are with the flexible of balance spring and around axis periodically positive and negative rotation (vibration).
For above-mentioned hair-spring balance, the vibration period is set in critically important in pre-determined specified value.If
Vibration period deviates from specified value, then the rate (daily rate degree) of mechanical clock can change.
The vibration period T of hair-spring balance is indicated by following formula (1).In formula (1), I indicates " rotary inertia " of hair-spring balance,
K indicates " spring constant " of balance spring.
【Formula 1】
According to formula (1), when the rotary inertia I of hair-spring balance or the spring constant K of balance spring occur due to temperature change etc.
When variation, the vibration period T of hair-spring balance changes.Specifically, there is a situation where as follows：Above-mentioned balance wheel is by thermally expanding
Rate is positive material (material expanded due to temperature rise) formation.In this case, when temperature is raised, balance wheel is expanding,
Rotary inertia I increases.On the other hand, there are following situations：Balance spring is had the material (example of negative temperature coefficient by Young's modulus
Such as, Steel material) it is formed.In this case, when temperature is raised, spring constant K is reduced.
Therefore, with temperature rise, rotary inertia I increases or spring constant K is reduced, and vibration period T is elongated as a result,.
As a result, the vibration period T of hair-spring balance shortens and elongated at high temperature at low temperature, the temperature characterisitic of clock and watch exists as a result,
It becomes faster under low temperature and slack-off at high temperature.
Therefore, the countermeasure as the temperature dependency for improving vibration period T, it may be considered that the materials'use of balance spring
Parelinvar (for example, cobalt-Ai Linwaer constant modulus alloys etc.).It is considered that：By using parelinvar, can inhibit
The variation of the spring constant K to accompany with temperature change, to inhibit the temperature dependency of vibration period T.But in order to inhibit
The variation of the temperature coefficient of Young's modulus needs strict manufacturing management, there is project as the manufacture for being difficult to carry out balance spring.
On the other hand, the countermeasure as the temperature dependency for improving vibration period T, it is also contemplated that following knot
Structure：At the position of rotational symmetry on balance wheel, bimetal leaf is set.Bimetal leaf is by the different plank stacking of coefficient of thermal expansion
And formed.
According to the structure, in temperature rise, due to the difference of the coefficient of thermal expansion of each plank, bimetal leaf is for example inside to diameter
Side deforms.The average diameter undergauge of balance wheel as a result, so as to make rotary inertia I reductions.As a result, rotation can be corrected
The temperature characterisitic of inertia I, so as to inhibit the temperature dependency of vibration period T.
Moreover, for example the following patent document 1 discloses such structures：Change the effective length of each bimetal leaf
(from balance wheel overhang outstanding), so as to changing temperature coefficient correction amount, (bimetal leaf is for temperature change in radial direction
On variable quantity).According to the structure, it is believed that：Each bimetal leaf is adjusted by the temperature coefficient corresponding to Young's modulus
Effective length, be easy to eliminate the deviation of the temperature coefficient of Young's modulus according to the temperature characterisitic of rotary inertia I as a result,.
Patent document 1：No. 256953 specifications of British patent
But for the structure of above-mentioned patent document 1, exists and be difficult to make the effective length of each bimetal leaf unanimously in this way
Project.If the effective length of each bimetal leaf is different, the center of gravity of hair-spring balance is relative to rotation axle offset.As a result,
The deviation that hair-spring balance occurs applies weight (piece weight り), to which the variation of the vibration period T caused by the posture by hair-spring balance becomes
(it is poor to generate so-called posture) greatly.
In addition, in the case where the material to balance spring uses parelinvar, according to the manufacturing process of balance spring (for example, molten
Solution or heat treatment) in processing conditions, the temperature coefficient of Young's modulus may change to positive or negative.
But in the hair-spring balance for having previous bimetal leaf, the temperature coefficient of rotary inertia I be (temperature characterisitic
Tendency) adjustment can only be carried out to the either side of positive and negative.

[temperature correction]
Next, in above-mentioned hair-spring balance 54, the method for adjustment of temperature coefficient correction amount is illustrated.Fig. 7 is
The top partial view diagram of the hair-spring balance 54 of action for illustrating adjustment section 100.In the state of Fig. 7, about bimetal leaf
121, in the state that low bulk component 130 is located at the 1st radial inside, low bulk component 130 and highly expanded component 131 are the
1 radially arranges.
As shown in fig. 7, in the hair-spring balance 54 of present embodiment, when generating temperature change, bimetal leaf 121 due to
The difference of the coefficient of thermal expansion of low bulk component 130 and highly expanded component 131 and flexural deformation.Specifically, relative to defined
In the case that temperature rise has occurred in temperature T0 (room temperature (for example, 23 DEG C or so)), highly expanded component 131 is than low bulk component
130 expansions are much.Side (the Fig. 7 of adjustment section 100 to low bulk component 130 and the stacking direction of highly expanded component 131 as a result,

It is shunk much than low bulk component 130.Adjustment section 100 is to the other side (the 1st radial outside in Fig. 7) of stacking direction as a result,
Deformation.
By making adjustment section 100 deform, as a result, the terminal part of adjustment section 100 and the 1st axes O 1 the 1st radially away from
From changing.Specifically, as defined in set when temperature T0, the terminal part of adjustment section 100 and the 1st axes O 1 be in the 1st diameter
Upward distance is R0, if when temperature change, the terminal part of adjustment section 100 and the 1st axes O 1 the 1st radially at a distance from be
In the case of R1, the difference of distance R0 and distance R1 become in the 1st radius varitation Δ R radially.Further, it is possible to become with radius
Change amount Δ R correspondingly makes the average diameter undergauge or expanding of balance wheel 62, so as to make hair-spring balance 54 around the 1st axes O 1

Amount.In case the temperature decreases, the average diameter of balance wheel 62 can be made expanding and increases rotary inertia.Thereby, it is possible to turning
The temperature coefficient of dynamic inertia is modified.
But as in this embodiment to balance spring 63 using parelinvar, according to the manufacture of balance spring
Processing conditions in process (for example, melt or heat treatment), there are the temperatures coefficient of Young's modulus to the possibility of positive or negative variation
Property.
In contrast, in the present embodiment, it can be changed corresponding to the temperature coefficient of the Young's modulus of balance spring 63 double
The direction of sheet metal 121 (around the rotation angle θ of the 2nd axes O 2).Specifically, tool is made to pass through operation hole 117 engaging in Fig. 4
Shown in adjustment section 100 engaging portion 135 in.Then, so that tool is rotated around the 2nd axes O 2, make fixed part 120 on one side as a result,
Peripheral surface slided on the inner peripheral surface of mounting hole 115, make on one side adjustment section 100 around the 2nd axes O 2 rotate.Rotation angle as a result,
Degree θ is changed.
Fig. 8~Figure 12 is the sectional view shown after amplifying adjustment section 100.
In the state shown in fig. 8, it is arranged on the 1st axis direction in low bulk component 130 and highly expanded component 131
Under state, low bulk component 130 is located at the face side of the 1st axis direction.Using the state as the reference position (0 of adjustment section 100
(deg)) the rotation angle θ around the 2nd axes O 2 is adjusted.For example, in fig.9, making adjustment section 100 from reference position around
45 (deg) are rotated on the clockwise direction (+direction) of 2 axes Os 2.In Fig. 10, make adjustment section 100 from reference position around
90 (deg) are rotated on the clockwise direction (+direction) of 2nd axes O 2.
In fig. 11, adjustment section 100 is made to be revolved in the counter clockwise direction of the 2nd axes O 2 (- direction) from reference position
Turn -45 (deg).In fig. 12, make adjustment section 100 from reference position on the clockwise direction of the 2nd axes O 2 (- direction)
Rotate -90 (deg).
Figure 13 is to show the rotation angle θ for making adjustment section 100 (when high temperature) at the same temperature in -90 (deg)~90
(deg) song of the relationship between in the case of changing between the, direction of bimetal leaf 121 and the deflection of bimetal leaf 121
Line chart.In fig. 13, X-axis indicates (hereinafter referred to as X points of the component along the 1st radial direction in the deformation vector of bimetal leaf 121
Amount.).In addition, (hereinafter referred to as Y points of the component along the 1st axis direction in the deformation vector of Y-axis expression bimetal leaf 121
Amount.).In this case, in fig. 13, -X direction is consistent with the inside of the 1st radial direction, and +X direction is consistent with the outside of the 1st radial direction.
In addition, in fig. 13, state when indicating defined temperature T0 positioned at the bimetal leaf 121 of origin (before deformation).
As shown in figure 13, in the case where adjustment section 100 is in reference position (0 (deg)), bimetal leaf 121 is only to the 1st
The face side deformation (A1 in Figure 13) of axis direction.Therefore, the Y in reference position, the deformation vector of bimetal leaf 121 points
Amount becomes maximum, X-component 0.In this case, radius varitation Δ R is 0, therefore the temperature coefficient of rotary inertia does not change.
When making adjustment section 100 be rotated from reference position to+direction, bimetal leaf 121 also becomes to the 1st radial outside
Shape, thus generate bimetal leaf 121 deformation vector in+X-component (A2, A3 in Figure 13).Also, by making rotation angle
θ becomes larger to+direction increase ,+X-component.That is, by making the rotation angle θ of adjustment section 100 be moved from reference position to+direction
Position, thus, it is possible to the incrementss of the rotary inertia of the hair-spring balance 54 when increasing temperature rise.Moreover, being 90 in rotation angle θ
(deg) in the case of (A3 in Figure 13), bimetal leaf 121 is only deformed to the 1st radial outside.Therefore, it is in rotation angle θ
In the case of 90 (deg) ,+X-component becomes maximum, Y-component 0.In this way, by making adjustment section 100 from reference position to+direction
Rotation, can increase the temperature coefficient of rotary inertia.
On the other hand, when making adjustment section 100 be rotated from reference position to-direction, bimetal leaf 121 is also radial to the 1st
Inside deformation, thus generate bimetal leaf 121 deformation vector in-X-component (A4, A5 in Figure 13).Also, by making
Rotation angle θ becomes larger to-direction increase, thus-X-component.That is, by making the rotation angle θ of adjustment section 100 from reference position
It is shifted to-direction, thus, it is possible to the increases of the rotary inertia of the hair-spring balance 54 when inhibiting temperature rise.Moreover, in rotation angle
It is in the case of 90 (deg) (A5 in Figure 13) to spend θ, and bimetal leaf 121 is only deformed to the 1st radial inside.Therefore, it is rotating
In the case that angle, θ is 90 (deg) ,-X-component becomes maximum, Y-component 0.In this way, by making adjustment section 100 from reference position
It is rotated to-direction, the temperature coefficient of rotary inertia can be reduced.

As shown in figure 14, according in above-mentioned Figure 13 as a result, making adjustment section 100 be rotated from reference position to+direction
When, the radius varitation Δ R of adjustment section 100 to+direction (the 1st radial outside) become larger.On the other hand, make adjustment section 100
When being rotated from reference position to-direction, the radius varitation Δ R of adjustment section 100 to-direction (the 1st radial inside) become larger.

To adjustment, to which independently rate is maintained fixed (referring to Fig.1 5 in solid line G3) with temperature change.
On the other hand, as shown in the G2 of Figure 15, according to the rotary inertia of the Young's modulus of balance spring 63 and hair-spring balance 54 it
Between relationship, in the case where rate has positive temperature characterisitic, with temperature rise, rate has the tendency that becomes faster.It is this
In the case of, so that adjustment section 100 is rotated from reference position to+direction.Thereby, it is possible to the directions for ensuring to accompany with temperature rise
The radius varitation Δ R in 1 radial outside, increases the temperature coefficient of rotary inertia, accompanies with temperature rise therefore, it is possible to increase
