Due to the need for ventilation and heat dissipation of electric drills, there is a lot of internal dust in long-term use. The dust will mix and deteriorate the lubricating oil on the gears and bearings (sliding sleeves) and dry up and increase wear, especially when used in alternative types. In order to ensure the rotation accuracy of the electric drill and reduce the excessive clearance caused by the wear of the bearing (slide sleeve), it is extremely necessary to keep the interior clean and add grease to lubricate.
Method:
Loosen a few self-tapping screws or screws outside the electric drill; lay it flat and open half of the shell; generally the structure of the new-style electric hand drill is semi-embedded, that is, all the machines and electrical components are installed in the other half of the shell;
Carefully remove the carbon brush first, then the drill chuck end, then gently lift the motor to take out the rotor (don't scratch the enameled wire), wipe the commutator on the rotor (the one in contact with the carbon brush), if it is too dirty Or if the abrasion is severe, it can be polished with emery cloth and then polished with water or metallographic sandpaper until it is bright.
If the front and rear bearings of the rotor are sealed, they can be wiped clean. If the seal is broken, they should be replaced in time. Wipe the helical gear shaft in front of the rotor clean.
Wipe clean the oil inside the shell. Clean the helical gear and the bearings (or bushings) on both ends of the drill chuck rod.
Reinstall the unloaded stuff, first install the rotor; then install the drill chuck rod helical gear; install the carbon brush, if the carbon brush is shorter than 7-8 mm, replace it in time. The carbon brush should be installed and flattened. Finally, find a little "Mobil" or "Shell" grease and add it between the gear pair and the bearing (or sleeve). All parts should be installed and flattened and checked for correctness. The other half can be covered. Tighten the screw, turn it by hand and feel no stuck, then power on and try it.
What should be paid attention to when using electric drill
1. The diameter of the drill used cannot exceed the allowable value of the electric drill.
2. The drill bit must be clamped with a key, and other tools cannot be used to strike the drill chuck.
3. Do not use too much force when drilling to prevent the motor from overloading. If the rotation speed is found to be reduced, the power supply should be cut off immediately for inspection.
4. The sporadic machining parts must be firmly on the fixture.
5. Cannot wear gloves.
