The device of the Bulgarian - the help of the master
To understand how the Bulgarian is arranged, the master should familiarize himself with the basic principle of the tool. With the help of electric energy, the engine of the apparatus is operated. Through a special gear, the engine transmits its rotation to the steel shaft, to which is attached a cutting or grinding wheel. High reliability of cutting operations depends on the number of revolutions of the cutting disc in one minute. Professional Bulgarians can perform up to 11.000 revolutions per minute.
Important! When choosing a tool, it is necessary to correctly compare its power and the number of revolutions.
Disassembly of the Bulgarian will help you see all its components. So, this device consists of:
- Plastic case, which is made of two parts;
- Electric motor of a certain power;
- Reducer, which rotates the cutting disc.
- All other components of this tool do not have design details that can affect the quality of the work.
Work on disassembling and assembling the
device Before deconstructing the bulgarian, you need to think about whether it is necessary? Such an action will be required only if there are malfunctions of the Bulgarian. Typically, such defects are due to the fact that the tool tries to start, but it does not work. In such cases, it is not necessary to disassemble the whole apparatus, because nothing will change from this. The problem may be that the graphite brushes located on both sides of the hull were worn out.
These brushes simply need to be unscrewed and replaced. These elements are twisted with a simple screwdriver, which does not require a complete parsing of the case. But if there is a need to replace the reducer or pinion, you will have to disassemble the tool completely.
Important! When disassembling it is necessary to remember plastic snaps on the tool body, so as not to break them.
In order to properly disassemble the cutting machine, follow the following procedure:
- To begin with, you must release the tool from the cutting disc and clamping washer. After that, the protective cover is removed, which is fixed in a clamp fashion.
- All the screws that connect the two parts of the plastic housing are now unscrewed. If you unscrew all the screws, and the case does not separate, do not be nervous and break the plastic. Just under one of the pasted seals remained an additional screw.
- When the case is opened, you do not need to shake out all the contents from it. Just remove one part of the cover, leaving the motor and all its components in place. The gearbox changes quite easily. It is necessary to pull it out and replace it with a new one.
Assembling the tool is more difficult than disassembling the
. Before assembling the Bulgarian, make sure that all the parts are in their proper places. It often happens that the master forgets to install one of the gaskets or washers, which leads to a non-working condition of the tool or its rapid deterioration. Important! When twisting all the screws on the plastic cover, try to get into the same holes where the screws were originally.
The unit must be assembled on the opposite side of the gear unit. This will allow the tool to be more evenly held on the desktop. After the final assembly, you need to see if there are any spare parts left on the table, after which you should check if the device works.
