Electric drill is a common tool in daily life, which belongs to one of the hardware products. Of course, there are also small electric drills for home use, which can be adjusted and replaced according to different gears. How to use the electric drill in gear 1 to 18. What is the specific method? What is the working principle and maintenance method of the electric drill? These contents are very important for everyone to understand the related issues and matters such as electric drills. Here is a brief introduction.
The working principle of the electric drill is the electromagnetic rotation and electromagnetic reciprocating of the motor rotor of the small capacity AC universal motor for magnetic field cutting and working operation. The operation device is driven by the drive mechanism to drive the gear to increase the power of the electric drill, so that the electric drill scratches the surface of the object and better penetrates the object.
There is a lot of dust inside the long-used electric drills, because of ventilation and heat dissipation. Dust mi, deteriorated, draws and dries lubricants on the gear and bearings (sleeves) and increases wear, especially in alternative use. In order to ensure the rotation accuracy of the electric drill, reduce the excessive gap caused by the bearing (slide sleeve) wear, and maintain the internal clean and grease lubrication is very necessary. Loosen several self-tapping nails or screws outside the drill; lay flat and lift half the shell.
