Why does the electric fan not shake its head?
Shaking the head is blocked because the connecting rod is deformed and bent. What will happen at this time? what's up Noise, the deformation of the connecting rod can be removed, and it can be eliminated after shaping;
It is the transmission fault that prevents the transmission of power. Check the toothed bar, vibrating plate, gearbox, clutch, etc. If it is found that there are phenomena such as falling off, foreign objects stuck, and serious wear and tear, the lost parts should be eliminated or replaced.
Electric fans mostly use oil-bearing which is usually a powder metallurgy product. Tightly wrapped in the oil hole inside the bearing for lubrication. When the electric fan works, the temperature of the motor rises, and the friction between the rotating shaft and the bearing generates heat, which will gradually consume lubricating oil. If the lubricating oil is not properly replenished, the fan motor will not be able to maintain normal operation, and the speed will be reduced or even turned, thus burning out the motor. During the use of the electric fan, you can refuel the electric fan from the oil filler every 1 ~ 2 months. Sewing machine oil or spindle oil can be used.
The reducer of electric fan uses lubricating oil (industrial vaseline or calcium-based grease), which is usually replaced once every 3 ~ 4 years. When replacing, first remove the back cover, remove the balance key, then remove the gearbox cover, gently scrape off the old grease inside with a small bamboo lamp tool, then clean it with clean gasoline, and then add a proper amount of new grease.
Working principle of electric fan shaking head motor
There is a gear box at the head of the fan. When the motor rotates, it drives the gear and gearheads drives the connecting rod. One end of the connecting rod is fixed, so it will shake its head when it rotates.
The working principle of an electric fan is to convert electric energy into mechanical energy by using the forced rotation of an electric coil in a magnetic field. The AC motor of the electric fan drives the blades to rotate after being stressed, and the blades rotate at high speed to generate wind, thus achieving the purpose of fan air supply. Due to the resistance in the coil, when the magnetic field rotates, part of the electric energy of the coil is converted into heat energy.
The structure of the electric fan, the rotor of the electric fan consists of magnets, blades and shafts; Its stator consists of silicon steel sheet, spool and bearing. The control circuit of electric fan is the internal excitation generated by ic induction magnet and magnet motor through circuit control and coil conduction, which makes the rotor rotate.
There are many reasons why electric fans don't shake their heads. These are just a few common methods. Generally speaking, if such a problem occurs, first look at whether it is the problem mentioned above, and then try to deal with it, so that the problem can be solved. In addition, you can learn more about the working principle of electric fan rocking motor, which is of great help to you.
