What is the watch? Well, you will say, from all sorts of wheels, springs, levers. And you will be right, but ...
In fact, the clock is primarily a case and a mechanism. So here. When there is sadness, someone "opens the champagne bottle" on wise advice to the literary character, and someone is looking for classes for hands. So, at the bottom of the box with spare parts, I was found in me a magnificent mechanism, a clock caliber rocket 2628.n, one of the best calibers of the USSR clock industry, if not the best. Bed alone. He stands like inserted. Consequently, the repassage will have. Okay, in French, this word means "ironing clothes", but we mean the general cleaning, lubricant and adjustment of the clock mechanism with its full disassembly. The caliber is not simple. In complications - an instant calendar.
Okay. This is a mechanism. We need a hull for him. There is! There is no matter what, but it is. As a medicine from boredom, we will create a marketage, put a caliber rocket 2628.n to the Chinese building. Let him like in it, so far we will deal with something more decent and relatives.REM: If someone souls the term "cutlet", yes for God's sake!
"So we begin" ©. For work, we will need two tweezers - direct and Mr., Puttzolz * - large and small, as small toothpicks will go. Turning, two here is enough. Optics, hour oils, oil engineering.
* - See thesaurus.
To lubricate one mechanism, up to five types of oils are applied. Butter for pallet and balance, for the engine, for repair and for spring. Moreover, for the first turn of the spring, a lubricant is sometimes used, especially for the first sprout sprout intended. Such subtleties. But we will come together by two universal - "702" for lubrication pair metal-stone and "701" for a pair of metal-metal. Here they are enough. These are inexpensive oils, but with their feature coped with great. Oils were bought on Aliexpress in which time, invoice, alas did not save.
Begin. We put the caliber on the "fast side" stand, and let go of the spring, holding the drum wheel stopper. Then remove the balance with the bridge and the gasket under it.
Wrap the clock clock up. Remove the arrows. To do this, we use the M-shaped tweezers by laying a pre-laying on the dial so as not to scratch it. I have such a device from a piece of old photoplinka.
Now remove the dial and plastic ring between it and platinum, lowering the two screws on the ends of the platinum of the mechanism (they are visible to the second photo from the bottom).
That's what's under the dial. Remove the washer, the scale of days of the week. Scale will be washed into the shampoo and cleaned with a soft squirrel tassel.
Now we have access to the calendar bridge. We unscrew the three mounting screws, remove the calendar bridge, neatly! - There are several springs and small details, seeking very quickly take advantage of so suddenly acquired freedom!
We disassemble the "slow side". Remove the wheels and levers of the calendar, bill and translated wheels, with straight sponge tweezers, remove the minute tribe. For the removal of a minute tribe we apply a little effort.
Gently lay out the details on a clean sheet of paper.
Slow side is free. We turn the mechanism. We dismantle the drum wheel, clockwork wheel. The clockwork wheel is mounted with a screw with left-thread. We will be attentive. Remove the details and bridge of the drum. The drum bridge is attached by three screws. Two short and alone long. Long screw also attached a drum wheel dog. We take it carefully, remembering the spring located under the dog.
Remove the Angrenage Bridge, Second and Intermediate Wheel.
We dismantle the central wheel bridge. Be sure to memorize which screw where stood. If you confuse, do not collect the repair.
Remove the anchor wheel, the bridge of the anchor fork and the fork itself. In this case, we mark the fastening screws. They cannot be confused with others.
But here the culprit of the clock stop is visible - that ternky black hairs, attached to the spear of the fork. Remove it.
So, we still have repair. Remove the repair cover, remove the translation levers, shaft, spring and cam coupling.
Platinum is free.
Watches are ready to take water, o, sorry, gasoline procedures. For procedures, use gasoline "Kalosha". The quality of gasoline matters. Some leave the raid. Some have a very bad smell. I managed to acquire this variety. It is possible to work with him even in the apartment if the window is opened. And the traces of the details does not leave. But if you do not find such, "gasoline for lighters" will also be consolidated.
The whole cleaning process did not work out. Hands in gloves, the face covered with the "petal" so that the gasoline mixture does not hide, and the action took place on the balcony, then you mean, in the fresh air. Brushes, dental brushes, poodscholts and paper hygroscopic napkins were attracted to help. The result - everything shines.
We put the arrows, we will remove the old destroyed varnish and we will apply new.
We put in order the housing (as far as possible). We wash out, clean, polish the glass.
as it was
And so it became
Let's say for this thanks to the tooth paste Prokudent :)
The best polyrolol (in my opinion, based on long-term practice) for watch acrylic stalks, not yet invented.
As it is customary to say, "the assembly of the mechanism is made in the reverse order." We will put the central wheel in place, with a lining of his stones, cover the bridge, we collect the Angrenage - install an intermediate, second and anchor wheel, cover it with all the Angrenage Bridge. Lubricate stones and trumps. Lubricate the spring and collect the drum. Install it in place and cover the bridge. We put the wheels of the drum and a clockwork wheel. Screeching with a spring on three or four clicks and check the scat from Angrenage - great!
REM:About the term "Skat of the wheel system of Angrenage" will tell more, since this is a very important point in the repair of watch mechanisms. If the spring is started, the agrenge that is not controlled by an anchor fork will begin to rotate freely at high speed. Rotation occurs in one direction. If the mechanism is assembled correctly and there are no braking factors, then at the end of the plant's belief plant, the wheels will turn on a certain number of revolutions in the opposite direction. It speaks of the correct assembly and maintenance of the caliber. If this does not happen, then the system has a braking moment, the reason for which you need to find and eliminate. I note that the check of the skate should be performed only with lubricated stones and ass. Such trops will very quickly fail in operation hours.
Install an anchor fork, a fork bridge. Lubricate the working faces pallet. We bring the spring to a couple of revolutions and check the pulse fork. There is beautiful. We put the balance. And - about a miracle! - The clock went. Now Bushona.
Gently, holding the "LIRA" by Putzchol, remove it. We remove Bushon, send it to gasoline, where it is safely scattered into two parts - overlighted stone and passing. We rinse, we collect, covering the oil "702" on the overhead stone, install on the balance sheet and, whispering the prayer and hopping the breath, gently send the LIRA into its grooves. UV! Now the same on platinum. Ready. We collect a calendar. Here the trick is to carefully, without breaking the cumulative spring, put a command wheel on the axis with a cam back of the week. With the fifth time we collect the translation levers of the calendar. We put the disk of the number and cover it all the bridge. Here we need a skill. But nothing. From the fifth time everything becomes in its place. Now we have been waters on the right place for the day of the week, removing the needle towards the lever of its fixation. Washer and washer in five shampoos dial with a plastic ring-space. I am fixed, check the calendar work, we carry it out until the moment of switching and put the arrows on the feet in this very position so that we switch the calendar exactly at 12-00.
We collect the mechanism into the case.
By pressing the feed, take out the clockwork shaft, set the caliber into the clock housing, fix the mechanism with a spacer ring and, pressing the suppression again, set the clockwork shaft.
Now exhibit the move and shoot in the device. Since it is far from each house there is such exotic as the PPC-7 (clock check device), then in practice it is quite applicable to a smartphone with the Clock Tuner program installed on it, which can be obtained from the Play Market Android. The free version of the program is more than enough for quite an adequate setting of the clock mechanism, but the full version is more informative. According to the display program, the graphics with a thermometer and a mobile balance setting a shower and a period of oscillations of 18000 VRNs. Voila - "In Thread"! The stroke error is minus four seconds per day. For such a mechanism - more than a great result.
Close the back cover "Clapper".
Ah, no, not all! Actually, for what all this was done.
I pone an easyness and decided that it would still be better with the dark arrows.... and on fashionable accessory
—Thesaurus. Angrenage - A set of wheels of the hourly mechanism. Actually, this is a device for transmitting the spring force to the trigger. Bushon - Node of the hourly mechanism, part of the incublon, protecting the axes of axes from damage when hitting and saving lubricant. Digging - Accurate installation of the equilibrium position of the balance. Pallet - Rectangular stones of anchor fork working with a crown of anchor wheel. There are input and outdoor pallet. Platinum - (Emphasis on the first "A"), on what, in fact, the entire clock mechanism is collected. Pay. Here is the soot of a round shape with a multitude of milling. Does not have a relationship to precious metals. Putzholz (from it. Putzholz) - a pointed wooden wand for cleaning and holding parts when assembling. Repair - Manual arrows transfer mechanism. Futor - Cylindrical part of the wheel for attaching the arrows. Zappa - The thinnest part at the end of the axis of the wheel, which is included in the hole of the stone.
Now, probably, in almost every house there are Chinese wall clocks on a conventional half-barrier finger battery (type AA), or a small electronic alarm clock with the same mechanism and a squeak. What they are good, it is ease of course, a quiet sound of work (ticking) and the ability to work with high accuracy during the year on one battery (with a good battery even more - two or more than a year). The device is very simple - a small stepper motor that turns 180 ° every second and three gears that transmit this rotation to the central second wheel. On this central axis there are two more wheels - minute and clock. The central axis with the second arrow turns to 1/60 minutes each second. Simply put it counts seconds. Further, everything happens, as in conventional mechanical clock - the small gear (trib) on the axis of the second wheel through the intermediate transmits the rotation per minute, it turns the bill wheel, and the rotation is transmitted to the hourly. Now a little more. Stepper motor. So it is called because, as it walume every second - turns, as I wrote 180 °. This is done very simply - the usual electromagnet with a core of soft sheet iron (in order to easily demagned) and two open poles, between which a magnet is placed, dressed on the plastic axis with a gear on one of the ends.
When the current pulse is applied to the reel from the quartz generator, the core is magnetized and sets the magnet to a certain position with its magnetic field. Exactly a second at a second, a new impulse with reverse polarity comes to the coil, that is, plus and minus on the electromagnet coil change places. The magnetic field at the ends of the core turns over and the magnet with a gear is also rotated. So happens every second and the second arrow counts the time. Two other arrows turn after her through their wheels and show time up to a second. On some o'clock, the second axis is shortened and the arrow do not put on it. This is done in order to bring the appearance of the clock to the ancient mechanical clock. They even put a pendulum, which is driven from a separate pulsed electromagnet and the clock looks quite believable by old. Although the mechanism is very simple, these watches are broken too. These breakdowns should not be compared with real hourly mechanisms, I mean the mechanical clock with a spring or guard plant. They are much easier. And they also have a simple breakdown. I used to repair such and similar mechanisms a lot, and now I have stopped the clock in the kitchen. I will repair them and in the course of the case I will tell you about it to you, my readers. Someone will be just wondering, and someone will help repaired their own.
Here in such a state they are removed from the wall. They have been going 15 years 15 and during this time I changed the battery several times and went over and smeared the mechanism once. By the way about "music". Free advice. Never put in electronic devices cheap saline batteries. I was engaged in the repair of any electronics since the beginning of the 80s of the last century, working in the life system and to our time. Most electronics problems are oxidized contacts and mucus falling from batteries inside devices. Since our alkaline alkaline batteries appeared on sale, I use only them. Prefer Duracell. They are more powerful and flow less, although it is very long to leave unattended without supervision. With the slightest bloating or leaks, it is immediately mercilessly disposed, and the contacts are thoroughly rinsed with water, then gasoline. I always do it! But do not allow water to get inside the housing. Gasoline can be. It will quickly dry and will not be closed. If the saline solution or pitch fell inside, do not hope that it dries. Just disassemble and rinse. Water. Wet brushes, without leaking. Rinse several times, dry ..., do not regret the gasoline, also rinse everything with a tassel, which is not possible. You can dry and you can slightly lubricate the contacts with oil (cream and plant it is impossible, it is better for machinery). Now we will analyze the clock. First, I remove the battery and get rid of the web. Now I unscrew from the opposite side of three screws on top and bottom of the housing, I remove two brackets while holding the glass and remove it. I also remove all three arrows, they are just tightly dressed on their wheels.
I turn the clock with the mechanism up. It holds on the place of the plate with three through legs. I unscrew three screws from them and remove this plate and the entire clock mechanism.
It is fixed from scrolling with two pins on the housing, which are included in the corresponding holes on the mechanism. On different mechanisms it happens in different ways. And some generally have a pressed sleeve with an outdoor thread, through which all three wheels with arrows pass through. The mechanism is fastened with a washer and nut right on the cluster of the clock, and the dial is put on top and another round nut.
But back to my mechanism. To get to the wheels, you need to pick up and slightly press the two brackets on the sides of the mechanism and one below near the battery compartment and gently remove the transparent lid. Do all this is better just holding a weight mechanism in your hands. And then you need to put it on any stand with an emptiness in the center. I will have this power tape. Just fits.
I remove the lid and look carefully on the wheels. If at least one bent tooth is visible on any of them, the repair is completed. This mechanism is suitable only for spare parts. But it is unlikely. More often, all of them are whole and only need to rinse them with gasoline with a brush. It happens that on the very first wheel, or rather, the gear of the stepper motor does not hold the magnet. It is tightly dressed on the axis or inserted into the mandrel (like mine) of this gear.
If just jumped, you need to put it in place. Most likely, the clock fell ... For work, you need to use tweezers from bronze or stainless steel, otherwise the magnet will "stick up" to it and it will be difficult to collect the mechanism. I pretend that we repair the clock with you. Pour all gears on the table and look at carefully. Most likely there will be no damage. The main difference between all the mechanisms of quartz o'clock, even wrist, from mechanical in that all gears are constantly in the unloaded state. There is no springs that constantly presses the teeth and the axis of the wheels. Here, they are loaded only during a short impulse once per second. To hold it from the reverse bounce or spinning under the weight of long arrows, three lever-free spruses are made on the second wheel in the form of an outflow on its tips, which are drunk along the plate of its installation and hold on the spot after a transition momenta to the next second forward.
Now check the stepping motor. It is made by a single unit with a board issuing second pulses of polarity. It consists of a generator of rectangular pulses stabilized by quartz with a resonant frequency of 32768 Hz. This frequency is selected for ease of electronic circuit. If this frequency is 14 times to divide in half, it turns out the desired second pulses. The scheme is made that at the outlet, the polarity of the pulses changes every second and has an output voltage equal to the nutritional clock - 1.5 volts. This is enough for turning the magnet with gear. We look at the place of soldering the coil to the board. It happens, they are oxidized and fall off. Then it needs to be carefully soldered into place. If the wiring is short, you can clear one or two turns from the coil. We check and rinse contacts from the battery to the contact site of the quartz generator board. We are also thoroughly rinsed with a brush magnet, its axis and a hole where they enter. Purify with compressed air using medium enema.
We put the engine on its place in the mechanism body, set the magnet on your place on your gear and insert the battery to place, after checking it with a tester or immediately new. We press the board to contacts on the mechanism housing and look at the magnet. He must scroll every second or at least twitch. You can check the operation of the electronic unit by the usual tester. We put it on the measurement of the smallest resistance and pressed the ends of the probe to the contacts in the diagram. The w / engine coil loads the circuit, and the power of the tester and the milliammeter perform the role of power and measuring the current consumed. The arrow of the device should be twitching every second, if not, change the proven places. The surroundings. Everything is fine. Now we are thoroughly rinse with gasoline all the mechanism, each wheel, all the teeth and their seats in the whole mechanism. Emphasize Carefully, with a tassel and purge . Do not hope for sight, one Sorink, which you will not even notice, can slow down the entire mechanism. Very neatly lubricate the axis of all the wheels. It is axes that are a little bit. Exterior we remove the blurring. Oil should be very small. Remember? The mechanism is unloaded, friction is minimally, and the oil is thickly with time.
There remains to collect all the mechanism together. You need to do it carefully. The wheels can not be confused, they all have only their place. If it does not get, try the other.
There is another wheel on the top transparent lid, or rather the head with a notch for scrolling the arrows and setting the time. Unlike mechanical clock, where it is recommended to twist arrows only forward, in quartz hours it can be done as you like, where much closer there and twist. Gently put the lid in place. Do not rush to snatch it right away. Pressing from different sides, we try to lower it evenly, so as not to click when it becomes only one side. You can press and adjust the axis of any wheel. We snatch the lid, insert the battery and look at the second wheel through the transparent lid. If everything went fine, it will move. Repair managed!
It remains to put the mechanism in place, install the correct arrows and glass. It should not cause difficulties, the only thing that can advise is to align the arrows. Put them on the glass and see exactly whether they come into contact with it. Usually, after removal, they require editing. We put them all at 12 o'clock in parallel to each other, you can scroll through them right out. We put time and look as they go. It is better to wait a little longer so that the glass does not have to take again.
I had to get a little straightforward arrow, she slightly clung to a minute short end. After they passed the night, I set the glass and hung them to the place. After two days. Flight normal!
In addition, I want to say that there are quite a few such mechanisms. In principle, all of them are the same. They may differ fastening to the housing, stepper motors and sizes of wheels and axes. Some parts at the bottom interchangeable, some - no. Previously had to have a lot of disassembly - donors of parts. Now it has become easier. These mechanisms can be ordered in bulk or buy piece, even in 1000 style stores. But as you understood, you can repair. Most often they break from dirt, spiders and cockroaches, sweeping batteries (as I mentioned) ...
Subscribe, Comment and ask. If someone just knows how it is done, it's good. If someone comes in handy in the case - excellent. Good luck.
P. S. Do not scold for unnecessary details. Someone will come in handy, the rest can slip and not read everything. When I write, everything seems important to me. Otherwise it does not work ...
I offer in this topic lovers to share your experience in independent clock repair, and to professionals to give wise comments and valuable advice. In my opinion, such a topic has not yet been, however, sometimes the forum-unprofessional members are repaired and restored inexpensive hours on their own.
And I'll start with myself.
I have this watch that I like
However, recently, I discovered that the calendar had a bad thing to work, the number of the month does not accurately get into the window in the dial
Shaking, tapping, multidirectional rotation of the arrows, shaman dances with a tambourine did not help
I decided to disassemble, but for one and you show.
Immediately make a reservation, I am not a watchmaker, I have no special education or professional experience, and in general, I do not have a job on working with the clock. So, do not throw hamsters in me, if something is wrong. Nevertheless, the constructive criticism of me is welcomed, and is accepted with gratitude
Nature to disassemble. Unscrew the lid.
Now I take off the Sector of the Automotive Sector. You can probably not do this, but I prefer to remove, annoying when it comes out of case. I'm so very not just
At the same time, it is possible to remove and smear the dirt.
Now pull out the crown head. To do this, I use this homemade tool from the pin glued to the chopstick. It is good in that if you overdo it with an effort, just a pin will break away from the stick, and the parts of the repair did not sink (as usual).
The clock is extracted from the case:
Now you need to remove the arrows. In order not to scratch a beautiful dial, it is better to put such a piece of paper:
We unscrew the ring holding mehangs in the case. It is mounted using two screws and leaf-shaped suckers.
To remove the dial, you need to let go of two screws. In the photo, one of them is shown in the red arrow. For the dial, I will take, put on clean gloves to work with a film.
The dial is better to remove immediately into the bag so as not to pour it with oil, gasoline and do not sneeze on it
That's what's under the dial:
Immediately draws attention that the clove on the ring with numbers was frozen on the tamper of the spring-loaded retainer, not overcoming it as it was conceived
Unscrew the calendar device.
It becomes clear that the flap of the retainer is some curved and irregular shape:
Caution with tweezers straighten it. Losing several times and miraculously found on the carpet
Gently collect everything in place, gladly noting for myself that the cloves now get up correctly, with caressing hearing a slight click
We check again and again. It works fine!
Before installing the shooter, smoking dust with a dial of a Belya tassel.
Before installing the shooter, you must remember that it is necessary to coordinate their position with the triggering of the calendar. That is, so that the number is changing around 12.00
Do not forget on joy to return the Sector of the Automotive Sector. At these clock, he is simply removed and put. Without screws.
When the clock is collected, you need to set the time and number. As you can see, now the number gets up clearly in the window in the dial
These are good hours, I want them to work well!
Thanks to everyone for watching!
