1.What exactly is a bearing?
A bearing is a component that helps an object rotate. As the name suggests, a bearing is a component that supports the rotation of a "shaft" in a machine.
Machines that use bearings include cars, airplanes, generators, and so on. The household appliances commonly used in our daily lives, such as refrigerators, vacuum cleaners, and air conditioners, also use bearings. In these machines, bearings are responsible for providing support to the "shaft" installed with wheels, gears, turbines, rotors, and other components, helping the shaft rotate smoothly.
Due to the use of many rotating "shafts" in various machines, bearings have become essential components and are known as the "food of the mechanical industry". This type of component may not look impressive, but it is actually very important. Without it, we would not be able to live a normal life.
What is the role of bearings in ensuring smooth operation of the machine?
The rotating "axis" and the rotating support part will definitely experience friction. Bearings are used between the rotating "shaft" and the rotating support part.
≪ Function 2 ≫ Protect the rotating support part to keep the rotating "shaft" in the correct position
The rotating "axis" and the rotating support part will bear a large force. Bearings can prevent damage to the rotating support parts due to this force, keeping the rotating "shaft" in the correct position.
It is precisely because of these functions of bearings that we are able to repeatedly use the machine for a long time.
