How to use electric drill gear 1 to 18: The numbers 1 to 18 on the front of the power drill are: Torque setting, which means it will skid when exceeding high torque. Colloquially, it is used to control tightening forces. The higher the number, the greater the power. How to set torque: First, you should know that torque is the force generated when the bit rotates. When the torque is exceeded, the electric drill will stop turning. Torque shall be set according to the scale on the drill chuck.
The working principle of electric drill is by electromagnetic rotation or electromagnetic reciprocating small capacity motor rotor magnetic field cutting and working operation, operation device driven by the transmission mechanism, drive gear to increase the power of electric drill, so that the electric drill scratches the surface of the object, better through the object.
How to maintain electric drills: Due to ventilation and heat dissipation, electric drills used for a long time have a lot of dust inside. Dust can cause lubricants on gears and bearings (sliding sleeves) to mix, deteriorate, inhale and dry, and exacerbate wear, especially in alternative use. In order to ensure the rotary accuracy of electric drill, reduce the excessive clearance caused by bearing (sliding sleeve) wear, keep the internal clean and grease lubrication is very necessary. Loosen several tapping nails or screws outside the electric drill; Lay it flat, lift half the shell.
In general, the construction of new hand drills is semi-embedded, meaning that all the mechanical and electrical components are mounted on the other half of the housing. First carefully remove the carbon brush, then remove the end of the drill collect, then gently lift the motor to remove the rotor (do not damage the enamelled wire), clean the commutator on the rotor (the one in contact with the carbon brush). If it is too dirty or badly worn, polish it with emery cloth first, then with water or metallographic sandpaper until it is shiny.
If the front and rear bearings of the rotor are sealed, the outside can be wiped clean. If the seal is damaged, it should be replaced in time. Remove oil from the shell.
Clean the helical gears on the drill collect rod and the bearings (or bushing) at both ends. To replace the removed parts, install the rotor first. Install the drill collect bar helical gear.
Install carbon brush: If the carbon brush is shorter than 7-8 mm, replace it in time. Carbon brushes should be installed and flattened. After all parts have been installed, flattened and checked, the other half can be covered. Tighten the screws. Only when the screw is turned by hand and not stuck, can the power test turn.
How to use electric drill gears 1 to 18. In fact, different gears have different functions. You can choose the right electric drill gear according to the specific purpose. According to the specific method of use. What is the working principle and maintenance method of electric drill? After using the electric drill in daily life, you can follow the above method to maintain the electric drill. In this way, the service life of electric drill can be extended and some abnormal situations of electric drill can be reduced.
