Types of perforators and their design differences

[shapanwwuom]

In addition to the impact movements created by the indirect rotation of the bearing, drilling holes with the tool also requires rotational movements. This option is implemented by means of a reduction unit, presented as a pair of straight gears.

Rotational and impact movements are created by the rotation of the shaft of a powerful electric motor.
It is due to the fact that the tool design uses a powerful impact mechanism that it can be used not only for drilling holes in concrete, reinforced concrete and asphalt structures, but also for performing such manipulations as chiselling, destruction, removal of ceramic tiles, etc. This tool is also called destructive, but this does not make it eternal.

There comes a time when the units and mechanisms of the iraq telegram data power tool break down, which requires the need for repairs, the cost of which in service centers is decent. Repairing hammer drills is not a difficult procedure, as it may seem at first, and for its successful implementation you will need to know not only the device and design of the tool, but also the principle of operation.

Before repairing a hammer drill with your own hands, you need to understand the different types of these tools.There are two types of perforators:

Straight, drill-type or pistol-type - all these names refer to hammer drills that visually resemble a drill. In the design of straight units, the engine is located horizontally, that is, in the same axis as the direction of rotation of the chuck. The task of the gearbox is only to transfer the force from the electric motor to the actuator. The main difference between a pistol-type device and a drill in appearance is that the hammer drill has a mode switch, as shown in the photo below.
Barrel drills are a special type of hammer drills in which the electric motor is located vertically.
