How to repair a screwdriver with your own hands

The screwdriver is a handy power tool that simplifies construction work. But the device may fail, and therefore some of its parts will have to be dismantled to fix it. The article will indicate how to disassemble the screwdriver correctly.

Principle of operation and main nodes

Before you start disassembling a screwdriver (for example, Bosch), you need to understand the principle of its operation, as well as find out what parts it consists of. The device differs from other electric tools by using a special mechanism that stops the rotation. This process occurs when the unit reaches its maximum resistance.

Purpose of all parts and assemblies of the tool - as they are called

Screwdrivers (for example, Elitech) are divided into several varieties - according to the way they work:

  • from the mains;
  • from the battery.

Regardless of the type, they have the same operating principle in terms of torque transmission.

The screwdriver consists of several main parts:

  • Electric motor.
  • Button to start the device.
  • Speed ​​controller with reverse mode.
  • Chuck.
  • Electronic control unit.
  • Reducer.

The electric motor rotates the spindle through a special gearbox. The torque is regulated by means of a clutch, a chuck is located on the spindle. Various "bits" are put into it. A screwdriver (for example, Metabo) is controlled by an electronic circuit.

Reverse mode works due to power supply polarity reversal. Continuous current equipment is used as the engine. It is designed to be connected to the AC mains. The excitation winding is connected to the armature winding in series, and is divided into several parts: before and after the armature.

Handsome Red-spicy orient, unisex scent - the beauty of this scent is that I personally feel all the notes here, except for ginger. A very beautiful and unusual composition (like many of the fragrances of this house), in the beginning even Coven shadows from Andrea Maack in the form of beetroot tops slipped through - very unusual. In the base, it sits beautifully with languid patchouli and labdanum. The color and name are fully consistent with the sound of the fragrance.
