Description
Technical field
The present invention relates to a kind of clock and watch with gear with have the clock and watch of these clock and watch with gear.
Background technology
Be in the clock and watch of representative with the mechanical clock, using very many clock and watch to use gear.This clock and watch form different shape with gear according to purposes, and through make up transferring power complicatedly.In the past; This clock and watch are mainly made through machinings such as stamping-out processing with gear, and the method that adopts in recent years is to utilize photoetching process (photolithography) technology of one of MEMS (MEMS:Micro Electro Mechanical Systems) technology to make.Because compare with machining, the machining precision of said method is higher, even and complicated outer shape also can make accurately.
Therefore, as one of method of utilizing lithography technology to make, known have such method: utilize the electroforming mould through the photoetching process manufacturing to carry out electroforming, this electroforming part is used gear as clock and watch.
But the operation that this method expends in electroforming increases, thereby is difficult to carry out high efficiency manufacturing.In addition, electroforming material such as nickel has the characteristic of hardness low (Vickers hardness Hv is below 800), mar proof difference.
Therefore, as shown in Figure 6, be necessary to carry out secondary processing, promptly become the stage portion 101 of oil groove portion with the terminal part of gear 100 at clock and watch.
Particularly, clock and watch owing to slide often, therefore require high abrasion resistance with gear, and in order further to improve mar proof and to indicate the time more accurately, expectation can further improve mar proof from now on.Yet, under the situation of the method that adopts above-mentioned electroforming, need be to the oiling of oil groove portion, and guarantor's oiliness of each oil groove portion can produce deviation and might can't guarantee advantages of good abrasion property.
On the other hand, another method as utilizing lithography technology it is also known for such method: the silicon (Si) that is adopted as semiconductor material is as mother metal, utilizes photoetching process that the mother metal of silicon is directly formed profile and is used as clock and watch and uses gear.
In this case, since different with above-mentioned situation, need not carry out electroforming, therefore can omit the operation that expends in electroforming.Yet silicon has hardness height (Vickers hardness Hv is thousands of) and the characteristic of toughness very low (toughness value is about 0.9) as directly only adopting mother metal, is difficult to guarantee sufficient mar proof as clock and watch with gear.
Therefore, adopting under the situation of silicon as mother metal, usually, implementing surface treatment, coming mother metal is protected through this diaphragm, thereby improve mar proof to form diaphragm.
As this surface treatment, known have a following method etc., promptly implements the method (referring to patent documentation 1) that thermal oxidation coats diaphragm or implement physical vapor deposition and handle the method that (PVD:Physical Vapor Deposition) coats diaphragm.
The diaphragm hardness that coats through such surface treatment is very high, for example can also form the diaphragm that Vickers hardness Hv is 1500～3000 high like this numerical value is shown.Therefore, use gear, can guarantee sufficient mar proof, need not carry out above-mentioned secondary processing and form oil groove portion, also do not need oiling as clock and watch.
Therefore, when the manufacturing clock and watch are used gear, be fit to adopt such method: adopt silicon as mother metal, and on this mother metal, coat diaphragm through surface treatment.
Patent documentation 1: Japan special table 2008-544290 communique
Yet above-mentioned existing method also leaves following problem.
At first, the diaphragm that coats through surface treatment has the hardness height and the high characteristic of unrelieved stress, must the attenuate thickness.If thicken thickness, then can accumulate high unrelieved stress, thereby and can produce big stress difference between the mother metal.Therefore, might make diaphragm and mother metal generation crackle that autoclasia caused itself or slight crack etc. because of this stress difference.Therefore must thickness be thinned to about 0.1 μ m～2 μ m.Yet,, therefore,, thereby can't guarantee sufficient mar proof sometimes even the diaphragm of high rigidity is also probably because of friction or bump etc. produce the phenomenon that film peels off because thickness is thin.
In addition, owing to also need carry out surface treatment after with the shape of gear the mother metal of silicon being processed into clock and watch through photoetching process, so manufacturing process increased, and not only can not make expeditiously, and influence cost degradation.
And, as stated,, thereby when receiving bump etc., deform easily or cracked (damaged) because silicon itself has the low-down characteristic of toughness.Therefore, for sliding often and the clock and watch that clashed into easily use gear, be difficult to expect high reliability.
Summary of the invention
The present invention makes in view of above-mentioned situation; Its purpose be to provide a kind of high-quality clock and watch with gear with have the clock and watch of these clock and watch with gear; These clock and watch not only can be made to realize cost degradation with gear efficiently; And have meticulous and high-precision outer shape, and mar proof is high, functional reliability is high.

(2) in addition, the clock and watch of the invention described above with gear in, said gear part also can form the thickness of homogeneous at whole face.
In this case,, thereby need not implement to be commonly used to improve the countermeasure of mar proof, promptly need not be provided with lubricating step (oil groove portion) that wet goods stores etc. because the mar proof of gear part itself has been guaranteed on ground fully as above-mentioned.Therefore, can gear part be formed the thickness of homogeneous at whole face, thus can be with the attenuate of thickness own.Therefore, can realize the lightweight of clock and watch, and can make the action (driven property) of gear well improve serviceability with gear.In addition, owing to above-mentioned stage portion need be set, therefore can be easy to realize the simplification of shape, and further realize cost degradation.
(3) in addition; The clock and watch of the invention described above with gear in; Said gear part also can be used gear part for escape wheel; This escape wheel has the tooth portion of a plurality of hook shapes with gear part, is formed with the fork watt sliding part that slides that supplies escapement lever at the terminal part of the tooth portion of said hook shape, and also can carry out Machining of Curved Surface to the bight of said tooth portion.
In this case, can make clock and watch use gear is to possess the escape wheel of escape wheel with gear part, and this escape wheel has a plurality of tooth portion with gear part, and the angle of said tooth portion is carried out Machining of Curved Surface (R processing).Particularly,, thereby can not cause distortion or cracked, and can the bight Machining of Curved Surface that the tooth portion that comprise sliding part is whole become smooth because the toughness of gear part itself is high.
Therefore, watt contact when going forward side by side line slip,, also easily both contact condition is maintained identical state even if variation has taken place the fork watt contact position with respect to this sliding part a little with sliding part at the fork of escapement lever.If be in the bight of tooth portion under the situation of outstanding state, can expect that so fork watt contacts with the bight line sometimes, contact with the tabular surface face sometimes, the two does not form certain way of contact.But, carry out Machining of Curved Surface through bight to tooth portion, because the contact condition that will pitch watt easily with sliding part is maintained in certain state, so can be with transmitting to escape wheel reliably from the balancing energy ground of pitching watt.

Below, above-mentioned escape wheel 130 is described in more detail.
Like Fig. 4 and shown in Figure 5, this escape wheel 130 is made up of escape wheel portion 132 that forms predetermined thickness and the spindle unit 131 that is driven into the center of this escape wheel portion 132.
Moreover Fig. 4 is the vertical view of intermeshing escape wheel 130 and escapement lever 142.Fig. 5 is the 132a of the tooth portion view of apparatus with escape wheel 130.
In addition, the escape wheel portion 132 of this embodiment is through the chamfering in enforcement deflashings such as barreling processing, bight, the calendering processing on surface etc.Therefore, as shown in Figure 5, for a plurality of tooth 132a of portion, the whole angle Machining of Curved Surface (R processing) that also will comprise sliding part 132b is for smooth.
In addition, the escape wheel portion 132 of this embodiment by can implement photolithographic material and compare the high material of hardness and toughness with silicon (Si), promptly be that the material of principal ingredient forms with silit (SiC).
In addition, as shown in Figure 3, above-mentioned last axial region 130a is arranged at the upper end of spindle unit 131, and lower shaft portion 130b is arranged at the bottom of spindle unit 131.In addition, below last axial region 130a, be provided with the escapement mill pinlon 130c of portion.As stated, the gear part 128d engagement of this escapement mill pinlon 130c of portion and No. four wheel 128, thus the revolving force that plays No. four wheels 128 of the 130c of escapement mill pinlon portion is delivered to the effect that spindle unit 131 makes escape wheel 130 rotations thus.
As shown in Figure 4, a plurality of tooth 132a of portion of the escape wheel 130 that constitutes like this and escapement lever 142 engagements.Escapement lever 142 has escapement lever body 142d and escapement fork shaft 142f, and this escapement lever body 142d forms T word shape by three escapement lever beams 143, and escapement lever body 142d constitutes through the escapement fork shaft 142f as axle and can be rotated.
The end of two escapement lever beams 143 in three escapement lever beams 143 is provided with fork watt 144a, 144b, at the end of an escapement lever beam 143 of remainder escapement lever box (~Ankuruhako) 145 is installed. Fork watt 144a, 144b are the ruby that forms the quadrangular shape, and utilize bonding agent etc. to be adhesively fixed on the escapement lever beam 143.
The escapement lever 142 that constitutes like this with escapement fork shaft 142f is being center when being rotated, and fork watt 144a or fork watt 144b contact the line slip of going forward side by side with the sliding part 132b of the 132a of tooth portion of escape wheel 130.And at this moment, the escapement lever beam 143 that escapement lever box 145 is installed contacts with banking pin (Dotepin) (not shown), makes escapement lever 142 no longer to same direction rotation thus.Its result is that the rotation of escape wheel 130 also temporarily stops.
Next, the manufacturing approach to above-mentioned escape wheel 130 describes as follows simply.
At first, after being ready to silit be the not shown substrate of principal ingredient, through photoresist films that coating is made up of photosensitive material on said substrate such as screen printings.Moreover, as photosensitive material, positive type negative-type can, but in this embodiment, the situation that has adopted the negative-type photosensitive material is illustrated.
Next, be ready to after pattern becomes the photoresist mask that opens wide in the zone beyond shape and its of escape wheel portion 132, with this mask alignment on photoresist film.Then, from the top irradiates light of photoresist mask, make the photoresist film exposure through the photoresist mask.That is, utilize the photoresist mask to be made public partly in not masked zone.
Behind the end exposure, remove the photoresist mask, the photoresist film that has utilized developer solution to make to make public develops.Like this, because photoresist film is a negative-type, the dissolving of therefore unexposed zone.Thus, modeled on the escapement gear portion 132 is partially removed to form the shape of the photoresist film is patterned manner, and the silicon carbide substrate escapement follow the outer shape of the gear portion 132 is exposed.
Next, the substrate to silit carries out etching and processing.At this moment, dry etching or wet etching can.The part that like this, optionally only the photoresist film after not formed by pattern is covered, be that the part of exposing of silicon carbide substrate is carried out etching and processing.Thus, can the substrate that be made up of silit be formed the escape wheel portion 132 with a plurality of tooth 132a of portion.
And, carry out etching and processing after, after utilizing solvent etc. to remove photoresist film, escape wheel portion 132 is carried out barreling handles, thereby carry out the chamfering in whole deflashing, bight and the calendering processing on surface etc.Consequently, can produce as illustrated in fig. 5 escape wheel its smooth Machining of Curved Surface, as shown in Figure 4 portion 132 has been carried out making in the whole bight of a plurality of tooth 132a of portion.
Particularly; Because escape wheel portion 132 is made up of the silit (SiC) than silicon (Si) toughness high (toughness value is about 3.5～5); Can not cause distortion or cracked even therefore carry out above-mentioned barreling processing yet, thereby can the bight Machining of Curved Surface that the 132a of tooth portion that comprise sliding part 132b is whole become smooth.
And then, carry out spindle unit 131 is driven into the operation at the center of escape wheel portion 132 at last, thereby can produce escape wheel shown in Figure 4 130.
As stated; The escape wheel 130 that produces according to manufacturing approach through this embodiment; Form owing to through lithography technology escape wheel portion 132 is carried out profile, therefore different with machining, can form finishing is the high-quality escape wheel 130 of meticulous and high-precision outer shape.
And,, therefore,, also can guarantee as the sufficient mar proof of clock and watch with gear even if coated diaphragm unlike implement surface treatment in the past suchly because escape wheel portion 132 forms by compare the high silit (SiC) of hardness and toughness with silicon (Si).Therefore, the operation that expends in surface treatment can be omitted, thereby cost degradation can be made and realize easily efficiently.
Particularly,, therefore can reach, thereby can become the excellent more escape wheel 130 of mar proof near adamantine hardness because the escape wheel 130 of this embodiment is formed by the material that with silit is principal ingredient.
Usually, escape wheel is because the slip number of times in 1 year surpasses millions of times, thereby is the unusual gear of easy abrasion.But, because the mar proof of the escape wheel 130 of this embodiment is very excellent, therefore, even if slip is not easy to wear often yet, reliability is excellent.
In addition, coat diaphragm owing to not implementing surface treatment, so the crackle that can not occur in the escape wheel portion 132 causing because of overlay film or slight crack etc.And,, therefore be difficult for deforming when bump waits or cracked receiving because the toughness of escape wheel portion 132 is high.Therefore, also can work steadily in the long term often even if slide, thereby can improve the reliability of work.
In addition, because the escape wheel 130 of this embodiment has been guaranteed the mar proof of escape wheel portion 132 fully, thereby need not be implemented in the 132a of tooth portion the countermeasure that stage portion (oil groove portion) that lubricated wet goods is stored etc. is commonly used to improve mar proof is set.Therefore, can make escape wheel portion 132 form the thickness of homogeneous at whole face, can be with the attenuate of thickness own.Therefore, can realize the lightweight of escape wheel 130, and can make as the action of gear good, thereby can improve escapement efficient.In addition,, therefore be easy to realize the simplification of shape, also realize cost degradation easily through this point owing to above-mentioned stage portion need be set.
Particularly, owing to utilize the silit of light specific gravity to form escape wheel portion 132, therefore form the excellent escape wheel 130 of starting and driven property easily, thereby make escapement efficient very excellent.
In addition; Because Machining of Curved Surface has been implemented in the bight of the 132a of tooth portion of the escape wheel portion 132 of the escape wheel 130 of this embodiment; Therefore; Contact when going forward side by side line slip at fork watt 144a, the 144b of escapement lever 142 and the sliding part 132b that is formed at the terminal part of the 132a of tooth portion,, also easily both contact condition is maintained same state even if fork watt 144a, 144b change with respect to the contact point of sliding part 132b a little.If be under the situation of outstanding state in the bight of the 132a of tooth portion, can expect that fork watt 144a, 144b contact with the bight line sometimes, contact with the tabular surface face sometimes, the two does not form certain way of contact.
But; Through Machining of Curved Surface is carried out in the bight of the 132a of tooth portion; Be maintained in certain state owing to will pitch the contact condition of a watt 144a, 144b and sliding part 132b easily, therefore can the balancing energy ground from fork watt 144a, 144b be transmitted to escape wheel 130 reliably.Therefore, also can improve escapement efficient through this point.
In addition; The mechanical clock 1 of this embodiment is owing to possess high-quality escape wheel 130; Cost degradation can made and realize to this escape wheel 130 expeditiously; And mar proof is high, functional reliability is high, so this mechanical clock 1 can become and can indicate correct time, high-quality clock and watch that functional reliability is high for a long time, and realizes cost degradation easily.
Moreover technical scope of the present invention does not receive the qualification of above-mentioned embodiment, various changes in addition in the scope that does not break away from aim of the present invention.
For example, in the above-described embodiment, having enumerated the situation of using gear to be applied to escape wheel 130 in clock and watch and be illustrated as example, but be not limited to escape wheel 130, also can be other gear.The load that can be preferably applied to especially to slide is high and require the gear of mar proof.
Specifically, both can be applied to No. two wheels, No. three wheels and No. four wheels, and also can be applied to self-winding various gear (transmit gear and transmit neutral gear) etc.
In addition; In the above-described embodiment; Having enumerated the situation that forms escape wheel portion 132 by silit (SiC) is that example is illustrated, but is not limited to silit, so long as can implement photolithographic material and compare hardness with silicon (Si) and the high material of toughness gets final product.
For example also can be aluminium dioxide (Al
2O
3), zirconium dioxide (ZrO
2) or silicon dioxide (SiO
2).Because these materials all satisfy above-mentioned condition, and, therefore can play and adopt action effect same under the situation of silit (SiC) in the characteristic that has aspect hardness and the toughness with silit (SiC) equal extent.In addition, can suitably divide these materials with the kind and the design philosophy of gear according to clock and watch.For example, in above-mentioned material, that toughness value is the highest is zirconium dioxide (ZrO
2), therefore, higher in expectation toughness, be difficult for can selecting this material under chipping etc. the situation of clock and watch with gear.
