There are unpleasant situations when an electric tool breaks in the midst of work, for example, a screwdriver. Time to go to the workshop or in a supermarket to buy a new no, it means it remains to repair it yourself. How to disassemble a screwdriver for repair Consider below.

How he is arranged

In the big move, the accumulator screwdrivers, so we will look at them. The screwdriver resembles a pistol with its appearance. In the housing made of plastic, there are holes through which the engine is cooled. If you look at the screwdriver in the context, we will see:

• roll control;
• reverse;
• attached to the radiator transistor revolt controller;
• electric motor;
• reducer.

How to disassemble a screwdriver in general

Consider this process on the example of the Makita screwdriver:

• disconnect the housing in which the battery is located;
• we unscrew the screws connecting 2 halves of the housing of the cross screwdriver;
• remove what is in the casing of the screwdriver;
• dismantle the reverse button;
• remove the speed switch;
• disconnect the engine and gearbox.

Disassembly is completed.

We disassemble the screwdriver battery

Almost 2/3 of the value of the screwdriver falls on the battery. Therefore, many repairs prefer to buy a new tool. But it happens that the person is used to working exactly this screwdriver and he does not want to change it. Then the battery pack will be premounced. Make it easy:

• if the case is collapsible, then we simply unscrew the fastener;
• in the case of an imaginary body, we remove the gluing layer, push the conjugate surfaces using the self-pressing;
• separate battery banks. Disassembling the accumulator of the screwdriver is made.

Here in this video shows another way of disassembly:

How to disassemble the cartridge of the screwdriver

The most mobile and loaded screwdriver nodes includes a cartridge. Naturally, it is wearing more often than other details.

How the patron is attached

Before disassembling the Mcite screwdriver, for example, we will determine the method of fixing the cartridge. This assembly node is fixed on the tool in the following methods:

1. Old, tested for 2 centuries Method - Morse cone. The taper of the lower opening of the cartridge and the shaft is the same.
2. The method called the threaded. The cartridge is screwed into the threaded part of the end of the shaft.
3. Method for fixing the cartridge using the fixing screw.

Determine how the manufacturer fastened the cartridge

Not knowing how the cartridge is fixed, we will not be able to disassemble it. That's why:

1. We look at it.
2. We read what is written in the side:

• if the inscription in the form of 1-6 B10, then in the design of the cartridge there is a Morse cone. At the same time, it is capable of clamping shanks with a diameter of 1 to 6 mm, and the cone surface has a sizes of 10;
• when the method of fixing the cartridge is a thread, then in the case of a metric, it is marked with 1.0-11 m12x1.25, and the marking of 2-13 mm ½-20 Unf indicates an inch thread. As a rule, our manufacturers use the metric thread, and foreign-inch.

We dismantle the patron

If the fastening of the cartridge is cone, it is removed simply - by cautious blows with a hammer on the body. When fixing the threaded, the following actions are performed:

1. On hourly, unscrew the screw with the left thread.
2. Press the hexagon in the sponges of the vice, we throw the key on it and hit the hammer on it. Thus, the cartridge will move from the spot. True, you can act differently:

• put screwdriver on the table;
• run it;
• to see if the cartridge was moved from the place when hexagoned the surface of the table was shifted.

It happens that these actions do not lead to anything, then the screwdriver will have to disassemble and then:

• take out the gearbox, and with it and the spindle;
• place a node in vice;
• take the pipe key and unscrew the cartridge.

If the gearbox hit the gear, then it should be done. Here is a scheme that will help to understand how to disassemble the Bosh screwdriver:

Here you see that in the Bosch screwdriver, the cartridge and gearbox is a single knot.

In detail how to disassemble the screwdriver reducer

Before answering the question, how to disassemble the chitachi screwdriver, bison, bosch or any other, it will not hurt to know their design.

Design of planetary gearbox

The gearbox includes the following parts and nodes in its design:

• gears - ring and sunny;
• satellites;
• drove.

They can be plastic or metal.

Principle of operation 2 steps

The gearbox works in this way:

1. Inside the ring gear, satellites rotate, which leads in motion the solar engine gear. At the same time, the speed drove less than the speed of the engine.
2. A torque from the first drove to the second is transmitted through the sun gear. The turnover was driving 2, which is connected in the shaft of the cartridge, are even more decreasing.

The 3-step reducer works in the same way, but there is another 1 planetary mechanism there.

Disassembly

This sequence is:

• remove the cartridge;
• we are promoting the housing;
• disconnect the gearbox from the engine;
• remove the plate;
• we take out all the details in order;
• unscrew the bolts connecting 2 halves of the gearbox;
• correct the diameter of the spring in a smaller side with the help of pliers. Thus, the inclusion of 1 transmission will improve;
• we disassemble the coupling by removing the locking ring, the washers and the bearing of the bulk;
• we take out the shaft.

To the question, how to disassemble a screwdriver, a video shot by the master of his case will be very by the way. It will answer and general questions and, in particular, how to disassemble the intercol battery:

But in this video, the disassembly of the Hitachi battery is considered, but using what they saw, we will know and how to disassemble the bison screwdriver, because they are arranged approximately equally.

Keep in mind: Repair kits for gearboxes Manufacturers are not released. Therefore, all you can do after disassembly is to clean it and change the lubricant. If the details were worn, then the repair is to fully replace this node. N. alice excessive amount of lubricant in the gearbox does not contribute to good the screwdriver.

And in conclusion: screwdriver to serve properly and it was not necessary to disassemble often follow simple rules:

• before work check how charged the battery;
• pick up the correct nozzle. Reference - the size of the screw or screws;
• after changing the nozzle correctly lock the cartridge;
• adjust the speed of rotation of the bits before work.
