How to collect the Bosch drill correctly. Types of punch and their constructive differences

How to disassemble the drill?

Greetings on my site! In this article I will tell you how to make out a drill. Its disassembly is necessary if there is some kind of breakdown or it is required to carry out preventive measures, for example, replace collector brushes or grease bearings.

The disassembly itself is simple. To carry out it, you will need a screwdriver of a suitable size. A knife may also be required, because in some places the case is pressed, and it is unlikely that it will work out with something else.

Here we will talk about the most popular variety of drills. A single.Speed shock machine. Over, there is no particular difference who produced it. Bosch, Makita, DeWALT or someone else. Everyone is similar to the principle. What’s outside, what’s inside.

• Put the drill with the side to the top with which the screws that fasten its body are screwed up, turn them out and separate the halves.
• Remove the cartridge and shaft attached to each other.
• Then you need to remove one of the brushes. To do this, start pulling it together with the brush holder. Only one can get it, since the second after that will not interfere. However, if you make their replacement, then get both.
• Next, unscrew the screws that attach the network cord to the body.
• Now the rest of our parts are free and can be extracted from their grooves. It is worth remembering that the engine with wires is connected to the button, so when taking out, be careful. Do not damage this connection, otherwise you will have to solder then.
• If you need to remove the bearings, you will need a special puller.

This is the disassembly of the case and its insides. Back. If you are also interested in how to disassemble the cartridge, then read on.

How to collect the Bosch drill correctly

If you have a need to purchase such a tool for the home and economic work as Bosch drill (Bosch), then you, first of all, need information about the drones of this world famous manufacturer. Over, the information is specific, objective and not overloaded with excessive technical details. It’s easier to say. Accessible to any “kettle” that does not particularly understand the nuances of technical terminology. It is this information that our site presents to your attention! You can get acquainted with our products you are interested in, and, finally, purchase the required Bosch drill.

I, Taras, sales manager of the company electric motor

The first where I want to start. We are official dealer of the company Bosch, We have a corresponding certificate, and give a guarantee that the Bosch products purchased from us are original. For any drill manufacturer warranty.

Second. Price. We are a large wholesale company. We have our own office, warehouses, transport. We buy a lot, and as a dealer, we get the minimum price. Bosch company has recommended prices, what all merchants should sell for. And lower below, as it were. But the market is the market. Someone is cunning, someone dumps, someone sells fakes. Therefore, we recommend that you find the lowest price, in any store, on any portal. Then, I advise you to call me, Taras by phone. 044 5 000 888, ask and of course get the price you desired. And having arrived at the office and making a purchase, get 100% present from the company and from me, whether it is a set for a drill, a drill, a suitcase.

Third. Once every six months I pass two.Day technical trainings on Bosha have appropriate diplomas. I think that not the last technical specialist in Ukraine. I will be happy to give any consultations on Bosch products, I will tell you about new items, they will help make the right choice

Where to start your familiarization? Let’s pay attention to the electrodelels that this famous company produces? First of all, you must ask a question to yourself: And how powerful Need a drill, What are the goals and objectives to her, what types of work she will have to perform?

For example, shock drill Bosch GSB thirteen re It is considered the most convenient in its class. It is, however, uniform, but for a home master. An assistant is an indispensable. After all drill Bosch GSB thirteen re It is very convenient in operation, and not least. Due to its compactness and small.Sized: its size does not exceed the size of the palm, and the weight is a little more than one and a half kilograms! At the same time, it is equipped with a reliable fast.Packed cartridge for the drill, the beginning of the drilling process provides a drill electronics, the number of revolutions is adjustable using the standard for most of such wheels. Such a drill, depending on the drill you have chosen, you can drill holes of the desired diameter both in wood and in steel, concrete and brickwork.

BUT Bosch PSB 500 RE drill. This is also a shock drill for domestic use, but differing from the above.Described its main parameters and characteristics. The principle of action, of course, is the same. But to unconditional advantages Bosch PSB 500 Its even smaller size and weight should be attributed, lower power. Both consumed and output. Also Bosch PSB 500 RE drill comfortable with a minimum of vibration, which will make your work tireless.

A great acquisition will be and drill Bosch GBM ten re. A model weighing only 1400 grams! It is ideal for drilling holes into steel with a diameter of up to 10 mm, and for drilling other surfaces is very convenient. Like the rest of the models drones Bosch, She has a convenient fast.Packed cartridge, which, in combination with ball and roller bearings, which are widely used in the design drills Bosch GBM ten re, ensures high accuracy of drilling and the long life of the tool.

Shock drill Bosch GSB sixteen re not so light, but this is perhaps the most productive tool of the family drones Bosch. Its power is great, which provides high performance. The design, which is characteristic of all devices of this brand, is compact and convenient. The gearbox is in a metal case, which perfectly protects it from mechanical damage and thereby provides a long service life. Dramatically new in this model is a handle equipped with an innovative mount, which guarantees a reliable capture of the tool.

All Boshevsky drills are similar to design elements and basic characteristics. If, for example, the diameter of the drilling of holes in one model differs from another, then it is slightly a few millimeters. But sometimes they can play the role, so this should be paid attention to. If the drill Bosch GBM ten re provides the diameter of the hole in steel 10 mm, then, for example, PSB 600 re drill Bosch guarantees the diameter of the hole in the metal up to 12 mm! And in wood, it is able to make a hole up to 3 centimeters! The weight of this model is 1.7 kg. Its electric motor is prayed enough to ensure excellent performance in domestic conditions. The speed of rotation of the drill here is regulated by the electronic system, and the adjusting wheel is used only to limit maximum speed. For a home master, such a drill is a real find! She, like her goods, is compact, excellently balanced and convenient in operation.

Types of cartridges

There are several types of cartridges. This must be taken into account before repairing the tool. In electrodels, fast.And.Packed cartridges are most often used. They allow you to easily change the drill during operation. This type of cartridge, for example, has an electric drill “Makita”, “Bosch”, “Hitachi” and T. D. Do not purchase cheap models with such a device. They quickly become unusable.

Four cartridges are used for shock drills. They are stable even when working in difficult conditions. The drill installation is carried out in such systems with a special key.

There is also a third category of cartridges. These are a cangy SDS patrons. There are 2 grooves in their shank. In this case, the drill is screwed into it and fixed with a locking ball. There are also 4 grooves in such a cartridge. Two of them are necessary for wedges of guides. The other two grooves perform a reliable fixation of the equipment. In such a cartridge, the spindle is automatically blocked after installation.

Breakage in the mechanical part. How to eliminate

The malfunctions in the mechanical part of the tool is easier to detect than in the electrical component. This is due to the fact that any mechanical defects are heard. The main signs of mechanical malfunctions of the devices under consideration include:

• The emergence of extraneous sounds
• Vibration and the battle of the clamping cartridge
• The operation of the engine engine is heard, but the cartridge does not rotate

To fix the device, and eliminate mechanical malfunctions, you will need, first of all, to disassemble the case. Knowing the device of the screwdriver, it will not be difficult to eliminate the breakdown in the mechanical part. If extraneous sounds arise, which indicates the reason for the wear of bushings and bearings of the anchor of the motor, then these elements must be replaced. With wear of the bearing and bushings, they need to replace them, but first you need to buy these details. When buying, difficulties may arise, since it is almost impossible to find spare parts for obsolete tool models.

It is interesting! Before putting a new bearing, it should be well treated with lubricants, for example, lutol-24 or solidol, and even better with special lubricants.

In addition to the failure of the bearing, a gearbox may break in a screwdriver. A number of malfunctions of this device include:

• Reducer shaft is twisted from the effects of large loads
• The working surfaces of the gear wear out
• A pin is broken off on which satellites are attached
• The bearing or supporting gearbox wears out

Most often, it is the gearbox that comes out of the system, or rather, its components. Toothed wheels. The reasons for the failure of the gearbox are:

• Incorrect operation of the tool
• Strong loads for which the device is not designed
• Lack of lubrication
• The material from which the devices are manufactured

If the screwdriver of the “old hardening”, that is, its gearbox consists of steel gears (instead of plastic ones), then it is advisable to repair it than to buy a new. To do this, the device needs to be disassembled, an inspection and find the cause of the malfunction. When repairing the gearbox, it is necessary to clean the mechanism and parts from outdated lubricant, and apply new lubricants. If there are damaged gears, then they need to be replaced. Do not rush to dispose of faulty gear wheels, as you need to buy exactly such details (take them as a template).

It is interesting! If plastic gears are installed on the tool, then changing them to steel is not recommended. The reason is that plastic gears are broken under the influence of large loads, which protects the engine from combustion. If metal gears are installed on the device from the plant, this suggests that the engine has a large power supply.

So that with independent repair of the mechanical part of the screwdrivers, no unnecessary questions arise, below there is a table that indicates the main signs of mechanical malfunctions, as well as ways to eliminate them.

Repair of the electric part of the perforator diagnosis of breakdowns and their elimination

Most often, as practice shows, the breakdown of the perforator arises in the electrical part, therefore it is with it that you need to begin diagnostics. If the tool works, but at the same time cracks, buzzes or makes other sounds, then the breakdown should be sought in the electrical part, so it is immediately recommended that you skip the point on the repair of the electric part and go to the elimination of breakdowns in the mechanics.

The diagnosis of the electric part depends on what specific breakdown arose. The device does not show signs of life or it works, but at the same time sparkles, smokes or periodically turns off. So, in order to fix the perforator without third.Party assistance, you must follow the instructions. Consider the main types of breakdowns and ways to eliminate them.

Drinks of diamond drilling

Models of this type are used for drilling high.Precision neat holes of large diameter in solid materials. The main feature of their design is the presence of a very powerful engine. As a working tool in such droplets, special drilling drills are used with a diamond crown. Models of this type “Bosch” are marked as gdb.

The manufacturer, among other things, equips all its tools of such a design with a liquid cooling system. If necessary, with the help of boos of diamond drilling, you can make holes in concrete with a diameter of 150-350 mm, and without much effort of the operator.

How to quickly remove the cartridge from a drill

Drill. One of the most important tools in the arsenal of the builder, master, and an ordinary householder. Over time, the bit stops holding, the drills fall out, the cartridge jams. This indicates a breakdown of the device. Most often, for the repair, it is enough to replace or grease the part, but it must first be disassembled. Any craftsman will deal with this, but it is worth considering the nuances of how to remove the cartridge from the drill.

Varieties of cartridges

A cartridge is a steel clamping sleeve and 3 identical fists (petal). The central part is called “tsanga”. Tsang elements are designed to fix drills, milling and taps. Can be used for the clip of the workpiece in the cold state.

• Quickly sounding. The most popular type of clamp. There are one.Flair and two.Lump. The first type. Fixes the sleeve manually by turning. The surface is usually corrugated, so it does not slide on the arm. The second. The lower coupling is held with one hand, and the other screws up the upper coupling in the direction clockwise.
• Fists. Are found on perforators and shock drones. Suitable for use in difficult conditions. The equipment is installed using the key.
• Cangy SDS patrons. Installed on drills manufactured in the 90s. On the tail there are 2 grooves of 1 cm. The drill is screwed and fixed with locking balls.

Before starting, you will need to deal with the type of mechanism.

How to remove the cartridge

The disassembly process differs, depending on the type:

Quickly joke

The threaded connection is characterized by a left.Handed threading thread. This is necessary so that when rotating the drill, the shaft is at the same time tight. Based on this, it is enough to hold the case for dismantling and scroll the cartridge clockwise.

Sometimes there is not enough ordinary rotation. You have to tap on the connection so that the thread disperses. Removal process:

• Inside is a screw. To access it, you need to dilute the fists and insert a screwdriver inside, then unscrew it from the groove.
• After removing the screw, the part is easily removed from the shaft.

Some models do not provide a latch. Then it’s enough just to swing the cartridge, but you will need more efforts. The key or another suitable element is fixed in fists, while at the same time the shaft is held by another key. Then the tools rotate in different directions.

Conical

For dismantling, just tap on the cartridge and turn it after each blow. Similarly, the fixing screw (right thread) is pre.Displaced.

Sometimes the cartridge wedges into the mount. To solve the problem, the element can be heated to red to soften the metal, cut it with a grinder or a jigsaw in order to subsequently remove it. After that you will need a new cartridge.

How to disassemble a cartridge on a drill

Not all varieties suggest disassembly, most often. Conical. There is an interesting access method without sawing into parts. Process:

• Fists come inward.
• Elastic material is pressed to the front side of the board or metal sheet (polystyrene, polystyrene foam-10-20 mm thick).
• The drill leans against the flat surface and shock work is turned on. If the model does not provide for this mode, then the cartridge is previously dismantled and fixed on the perforator. After 20 seconds of work, the part can be disassembled for repair, cleaning.

Even after the repair, the performance is not fully restored, because it is recommended to replace the part.

Electric motor verification: causes of breakdowns and repair

There are several reasons for the breakdowns of an armature or stator drill. First of all, it is illiterate operation of the device. For example, many users simply overload the tool, working without a break. This leads to the fact that the drill engine does not have time to “relax”. The second reason lies in a bad motor wire, which are often found in cheap models. That is why the breakdowns of cheap tools are much more common. Repair in this case must be carried out using a specialized tool. And it will be better if you entrust this work to professional specialists.

However, if it was decided to carry out repairs on your own, you will definitely have a question. How to do everything right? As you already understood, the electric drill “suffers” with breakdowns of the anchor and stator, and this can be checked by several signs, for example, when when working, the tool suddenly sparkles. If there are no “bright” signs, you can use an ohmmeter.

• First, carefully disassemble the device body;
• Remove the wires and all internal details;
• After clarifying the reasons for the breakdown, we change the spare part to a new one, the case is closed again.

Drill, punch or battery drill? Types and use of drills. Tools store

Once manual tools were used for all types of repair work. With technical progress and the need to accelerate and facilitate their work, they are gradually replaced by power tools. The most common and useful of these tools is undoubtedly a drill. This device is indispensable and widely used in workshops, households and construction sites, as well as in many other places.However, a wide range of application, different handles and parameters can confuse, which is why it is easy to get lost in search of an ideal drill. In this article I will describe all the possibilities and areas of application of various types of drills to help you choose the perfect solution for your specific needs. I invite you to read!

Why can you use the drill?

Before we even discuss the characteristics of each type of drill, it is worth considering what its use will be in the future.A wide range of possible works that can be performed using a special drill includes, among other things:

• Drilling various materials such as metal, wood, plastic, etc.
• Drilling and drilling holes in brick, plaster, stone and concrete, and even reinforced concrete
• Drilling holes in porcelain, glass and ceramics
• Forging and expanding holes in concrete
• Demolition of walls
• Various installation or construction work, for example.Assembly of shields of c/g, installation of lighting, laying cables, including inaccessible and poorly viewed places
• Finishing work and furniture assembly work
• Many other, less common tasks, such as: polishing, grinding, mixing.

As you can see, a drill is a tool that can be found almost everywhere. However, due to the specifics of the work, it will be necessary to consider the corresponding type of this device and spend some time choosing specific parameters

Power, revolutions, power. What parameters are characterized by drills?

One of the main parameters characterizing the drill. The nominal power is.As a rule, the greater the power of the device, the easier and more effective the drilling in the selected material. It is worth considering whether we will use the drill for professional or industrial purposes or at home. Then even a lower power, about 600 watts will be an ideal solution.

Another important parameter, regardless of the type of drill, is the power supply unit. Battery drill shurupert usually more expensive (except for the tool we still need a battery and charger), but provides a greater maneuverability of the device.In addition, it can be used wherever necessary, regardless of the presence of a network power source. Network drill limits the possibilities of places where we can use it, but it is cheaper than its battery analogues, and is also more reliable. There is no risk that the battery will be discharged during operation.

Rotational speed. Another important parameter characterizing the drill. This is important in the perspective of drilling in different materials, where the optimal speed may vary.Many drift models have speed adjustment, which allows you to easily adjust their value to working conditions.

It should also be noted that we may have a different drill cartridge in drones. One of them is a self.Locking drill cartridge, in which the user can install a drill, turning the cartridge case so that the fists are self.Centered towards the drill. Another type is a key cartridge. The key in such holders turns the ring that brings the lips closer, allowing you to install the drill.

Punch or unstressed drill. What to choose?

Unstressed drill. This is a light and compact device that is ideal for operation mainly with wood, plastic and soft metals. In addition to a small weight that facilitates the work and maneuvering the device, they are also very affordable in price. For little money, you can get a shock drill from well.Known companies, such as, for example.Makita or Bosch. If we are sure that we will work mainly with soft materials, from time to time and with easy homework, without the need for drilling, for example, in concrete, an unstressed drill is an ideal solution that professionals are increasingly choosing more and more often.

Hammer drill Ideal for hard work.Thanks to the use of a blow, you can create holes in solid materials, such as: brick, concrete, stone, ceramic plate. They are also more durable and capable of continuous work compared to drifts without a perforator. Most models also have several drilling options (with or without mechanical influence), which also makes them universal in use. Two types of mounts are most often used. Using a key cartridge and a self.Absorbing cartridge. Having decided to purchase a shock drill, we get a tool with a wide range of use, which will be indispensable for any repair and construction work of the house or in the garage.

Shock drill and shock drill. Differences

When choosing a perforator, it is worth knowing the differences of this device and a perforator.The main difference is that the punch has a pneumatic blow that requires much less effort than a mechanical blow used in perforators. Due to adaptation to more hard work and processing of solid materials, punch also have greater weight and design. The SDS cartridge used in devices of this type also allows us to adapt a wider set of accessories, including a bite that allows forging. Therefore, the SDS drill It will be a more suitable solution if you are planning more difficult construction work or repair.

It is also worth noting that in the case of perforators, these machines usually have two types of handles:

Scheme of Detail Drill Bosch 2 22

The most widespread among the professional builders of Russia were Bosch perforators, and among lovers, household models Bosch 2–20, 2–24, 2-26.

Perforators not only work well, but also easily repaired. You can easily find any part, failed part.

Boxing Drill. Skillsdrills.Org

In the designs of the described punch, the same principle is laid down to transmit a rotational moment from the rotor to the shaft of the shock block with the simultaneous transmission of a progressive pulse to a working tool.

Structurally performers are made according to the same scheme, but individual nodes or details have their own characteristics.

If you know the specific differences between the models of the described Bosch perforators, then disassembly and repair with your own hands will not be difficult.

Along with the originals in the Russian market there are a large number of tool fakes, including Bosch perforators.

Below are the design features of the models and methods for their disassembly and repair with your own hands.

The principle of operation of the punch Bosch

The principle of operation of the perforators is the same, but the design features differ.

The main details used in the listed Bosch perforators are interchangeable. This applies to a mechanical and electric node.

But there are nodes and did, characterized by the details used.

To carry out repairs of the punch 2–20, 2–24, 2–26, we must know these differences. Knowing the design features of each perforator facilitates the process of repair, finding breakdowns and their elimination.

Bosch perforators designs are so simple that they allow you to perform simple repairs, almost with your own hands and replace any part without contacting the service. We must have the skills of the collector, have elementary knowledge of electrical engineering and understand the principle of the operator’s operation.

Preparation for work

You need to prepare for disassembling the Bosch washing machine. This is done so that in the process of performing the main work, you did not have to be distracted by searching for the tool and other little things.

Actions that perform at the preparatory stage:

• Clear the place where the analysis of the technique will be carried out. It is inconvenient to do in the bathroom. It is better to take the machine to open space with good lighting.
• Cover the floor with cardboard or dense film. This will protect the coating from garbage and scratches.
• Prepare boxes for bolts. Each of them is best signed so as not to confuse the screws.
• Disconnect the device from all communications, extract the drain hose from the runoff, and de.Energize the device.
• Prepare a phone that is convenient to remove the analysis process. Subsequently, the photos taken will allow you to quickly and accurately assemble a washing machine.
• Prepare a container for draining the remains of water from an emergency hose. Rags for collecting liquid will not be superfluous.

Minimum set of tools:

• Set of screwdrivers or screwdrivers with different nozzles;
• A hammer;
• Passatigi;
• End and rye keys;
• Lubrication, for example, VD-40-it will be needed if the details or bolts are rusted.

When all the tools are prepared, you can proceed to the main stage.

How to repair a Bosch drill?

Can someone know how to repair a Bosch drill.Contact disappears in the reversal switch. And the contact itself is inside the engine. I don’t know how to get to him. Maybe someone has come across.

You did not indicate the model ! Most likely you have the contacts of the reversal and stator switch ! Maybe just somewhere a cable is too much too much or problems with brushes !

Write a model or show a photo. Bosch has a lot of drills with different performance. It is difficult to advise without knowing the constructive. Nevertheless, it seems to me that your reverse is designed in a brush.Holder (usually white), one part of which is fixed with two screws on the stature and motionless, the other rotates. Between them are switched contacts. Look at their condition. As a rule, the brush holder in such cases changes.

Model Bosch GSB 13re Professional. Photo in analysis [

Contact disappears when switching a reverse. How to get to this contact?

Well, yes ! Change the reverse switch and you will be happy !

The whole problem is that I do not understand how it understands.

Pull the rotor carefully, without damaging the coal brushes, push the brush.Holder with a thin screwdriver and remove !

The very design of the brush holder, if my memory does not change me, is disassembled by scrolling and patching small latches !

Good drill. Just in case, look at the scheme: enter the drill model in the line “corporate name” on this page:

If it is still not clear, tell me, I will sign it on the items. You need to expand the rotary part of the brush holder in any direction by 90 degrees. In this position, it will withdraw from hooks on a fixed part. You will see everything there already. When turning, it will pass through the latches (with effort, but neatly)

I can’t even remove the engine from the case. How to do it?Something does not give. Take everything in the collection?

Slonikdva and a gearbox, circled in the photo green from the body, is separated? If yes, then separate it, raise the back of the engine along with the stator (for this you have to raise the button and remove the reverse lever). Then, as you were told, turning the part, circled by red by 90 degrees, separate it from the stator. Having removed this detail you will see contacts on this detail itself and to the details to which it was attached. These contacts must be cleaned, and if necessary, bend down. Judging by the photo, you need to grind the collector, well, wash the case. In warm water with soapy soothele.

Typical breakdowns of the tool

Knowing the device is an electric drill, it is easy to determine the reason why this or that function does not work. It should be noted that it is possible to avoid breakdowns of power tools if preventive work associated with the replacement of the lubrication of the mechanical parts is periodically carried out.

After completing the drilling, it is necessary to remove dust from the tool, especially its ventilation holes. The nature of the malfunctions is divided into electrical or mechanical nature of the occurrence.

Electric damage

This type of breakdown occurs due to the exceeding the permissible load on the device and violations in its operation. They are manifested in the refusal of the tool to include, in a fault of reverse or a speed regulator. Most often, to restore performance, you will need to disassemble the start button and clean all the places associated with the electrical contact.

The appearance of the smell of Gary indicates the occurrence of overload in the operation of the electric motor. In this case, at first, the condition of the brushes and windings is checked, the places of connecting the power wire for the lack of burning are studied. Burning is associated with dusting, as a result of which the transition resistance increases, which leads to heating. Electricity malfunctions are easily calculated using a multimeter and visual inspection.

Mechanical breakdowns

Mechanical malfunctions are more difficult than. This kind of breakdown is usually accompanied by the emergence of extraneous sounds, and it will not work to eliminate them without disassembling the tool. In the case of poor fixation of the drill in the cartridge, it will be necessary to replace it, since it is impossible to restore the wear of the toothed connection on its own.

The emergence of a wedge during work associated with damage to the gearbox or bearing. If you disassemble the device, then the damaged node will be visible immediately. Wear of the gears or helmet will talk about the need to replace them. Bearings are checked by swaying them on the shaft. If the movement is not smooth or extraneous sounds are heard, then the bearing is replaced. After it turns out to find a faulty node and fix it before assemble the device back, it is necessary to clean the gearbox from the old lubricant and apply a new one. Then the device will be able to last more than one year.

Bosch drill. Equipment combining high assembly quality, German reliability and durability. The devices of this brand are widely used in construction and repair work of any complexity. They are preferred by home masters-amateur and professionals.

The Bosch family of drills is so extensive that everyone will be able to choose an unit with the necessary technical characteristics and the required functionality.

How a simple repair of the drill button with a speed regulator is performed

If the preliminary verification showed that the network wire is working, then continue searching for a malfunction on the current circuit. The next element in the queue for a fault is a button. On Soviet droplets, such buttons are a simple mechanism through which we close the contacts. On modern tools in the design of the trigger, a round regulator is placed in the form of a washer with resistors, which adjust the speed of rotation of the cartridge.

If the drill button does not have a regulator, then identifying and eliminating the malfunctions is quite simple. To do this, disassemble it, inspect the integrity of the contacts and clean it with fine.Grained paper sandpaper.

If an additional reverse switch is connected to the button, then it must also be checked by calling. If it is established that the breakdown is associated with the fault of the button, then it is easier to replace it than to look for a malfunction and try to eliminate it.

Problems in the electric network

Before disassembling the drill, you should make sure that it is disconnected from the network. Any disassembly begins with the removal of fasteners. Then we unscrew the screws and screws, remove the upper part of the product. All components remain at the bottom. The Drill Electric Scheme is happy. There is no need to separately describe all the elements, everything is already intuitively clear.

Naturally, it is much more difficult for models with electronic adjustments, but it is unlikely that it will be possible to repair a drill with such nodes, it is better to entrust it to specialists from the service center.

Connection cord

When food disappears, you only need to change the position of the product. The reason lies in the cable, most likely one of the wires has broken off. It is necessary to turn off the drill from the network and check using the multimeter cable. You can use the simplest option. A light bulb and a battery in one chain.

Attention! Tour the cord when the drill is included in the network is strictly prohibited, in order to avoid a short circuit. You will have to rewind the winding of the electric motor.

After the check, you can bend it as you like to find the cliff, then part of the cable is cut, the wire is cleaned and new contacts are created to connect. When the cliff occurred in the middle of the cable, it must be completely changed to a new. True, economical users prefer to combine ragged wires by soldering with subsequent reliable insulation of the repair site, but there is no longer any confidence in such a wire.

Power button

This part has a very simple design, but if problems arise, it will prevent the drill. Its work is simple: the key glides in a special block, and the contact closes with a pusher with a finger. Dust, which prevents the button to move and blocks it, preventing it from closing the contact circuit, from the long operation of the block. The defect is eliminated simply. Open and remove dust with a brush.

Important! Never try to lubricate the sliding surfaces of the button. The dust is mixed with grease, and the production occurs, as a result, the entire unit should be replaced.

To repair the drill button, you need to remove the side wall, check the integrity of the contacts. Когда образовался нагар — зачистить контакт мелкой наждачной бумагой. In case of burning contact, we change the entire block.

Rotor brushes

Not all users know that power from the network to the rotor is transmitted using brushes made of graphite. During normal operation between them and the rotor, constant sparking occurs. There are times when a wad of dust was piled between the anchor and the brush, and since the dust is a dielectric, the drill will not work until we delete dust and restore contact.

When working, the brush gradually decreases, because their lower part is erased. Periodically they need to be inspected and changed. This is not difficult to do, only you need to have a new set in stock.

When you noticed a strong sparking in the area of ​​the brushes, and changed them recently, this can happen because of problems in the rotor or its collector.

Check the rotor

For a thorough check, a rotor is neatly removed from the stator. Contacts can be charred or have a scale. You need to clean them with sandpaper strictly during the rotation. The reason for the appearance of scale may be prolonged work at maximum speeds. How to check the rotor for serviceability? Call neighboring lamellas with a multimeter. Their resistance should be identical.

Do not forget to check the winding whether there was a short circuit with the magnetic circuit case. In case of breakdown, a faulty winding is rewinded independently or attributed to the service center.

Stator Drill

A visual inspection must be done periodically: when overheating, when the product worked with maximum loads, a protective varnish could melt and an interval circuit occurred. The winding in this case will block, and the electric motor for further operation is unsuitable. The check is done in the same way, as in the case of the rotor. Check using the multimeter of the winding. If a breakdown is detected, the stator winding is subject to rewind.

Leading manufacturers of shock drills pay special attention to protecting the wires of the winding, because their products work in a special mode.

Replacement of a drill cartridge

Finally, the most trivial problem: the drill is turning in the cartridge, the degree of clamping has become very low. And not everyone has an idea of ​​how to remove the cartridge for replacement.

Let’s start with the most complex specimens: in drones with a capacity of more than 600-800 watts, the cartridge can have a wedge-cones landing. The spindle is made in a sleeve, into which the shank of the cangy cartridge is inserted. To remove it, you need to find a hole on the side of the sleeve, insert a powerful screwdriver into it and put the end of the shank, pushing it out. If there are no holes, the sleeve is clamped in a vice, and slightly blows through a wooden bar are applied along the cartridge. In this case, strokes alternate at diametrically opposite points from four sides.

In low.Power drillers, the spindle has an external right thread at the end, on which the cartridge is wound, and the hole in the center with the left thread, where the shunting bolt is twisted. This bolt has a head under a four.Sided or cross screwdriver, it must be twisted. Then, having blocked the engine impeller with a nail, try to tear the cartridge counterclockwise with a sharp but moderate force. If the thread boils, the drill will have to be disassembled to squeeze the spindle along with the driven gear in the vice.

Can someone know how to repair a Bosch drill.Contact disappears in the reversal switch. And the contact itself is inside the engine. I don’t know how to get to him. Maybe someone has come across.

You did not indicate the model ! Most likely you have the contacts of the reversal and stator switch ! Maybe just somewhere a cable is too much too much or problems with brushes !

Write a model or show a photo. Bosch has a lot of drills with different performance. It is difficult to advise without knowing the constructive. Nevertheless, it seems to me that your reverse is designed in a brush.Holder (usually white), one part of which is fixed with two screws on the stature and motionless, the other rotates. Between them are switched contacts. Look at their condition. As a rule, the brush holder in such cases changes.

Contact disappears when switching a reverse. How to get to this contact?

Well, yes ! Change the reverse switch and you will be happy !

The whole problem is that I do not understand how it understands.

Pull the rotor carefully, without damaging the coal brushes, push the brush.Holder with a thin screwdriver and remove !

The very design of the brush holder, if my memory does not change me, is disassembled by scrolling and patching small latches !

Good drill. Just in case, look at the diagram: enter the drill model in the line “corporate name” on this page: “

If it is still not clear, tell me, I will sign it on the items. You need to expand the rotary part of the brush holder in any direction by 90 degrees. In this position, it will withdraw from hooks on a fixed part. You will see everything there already. When turning, it will pass through the latches (with effort, but neatly)

I can’t even remove the engine from the case. How to do it?Something does not give. Take everything in the collection?

Slonikdva and a gearbox, circled in the photo green from the body, is separated? If yes, then separate it, raise the back of the engine along with the stator (for this you have to raise the button and remove the reverse lever). Then, as you were told, turning the part, circled by red by 90 degrees, separate it from the stator. Having removed this detail you will see contacts on this detail itself and to the details to which it was attached. These contacts must be cleaned, and if necessary, bend it. Judging by the photo, you need to grind the collector, well, wash the case. In warm water with soapy soothele.
