Reduce the friction of mechanical motion, introduction of common truck center bearing

For truck center bearing, basically as long as the history of human industry, it is as long as it is. For a truck, it is not clear how many bearing parts are on the body. But one thing is clear, if the truck does not have bearings, it is a pile of scrap iron. Today we will analyze the bearings in these trucks.
The truck center bearing is actually a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the shaft center position fixed. The functions of all bearings are actually the same, fixing, supporting, preventing axial rotation and so on.

● truck center bearing are very common in vehicles
In vehicles, ball bearings, also called ball bearings, are used most frequently. Ball bearings mainly consist of four basic elements: balls, inner ring, outer ring and retainer. The balls and rings are usually made of high chromium steel. The balls are installed in the middle of the inner ring and the outer ring, and can rotate while bearing a large load. Ball bearings have low frictional resistance in rotation, and at the same speed, the temperature due to friction will be relatively low. For example, self-aligning ball bearings, deep groove ball bearings, and thrust spherical roller bearings are all ball bearings.
The needle roller bearing is also an indispensable bearing part for trucks. It is a roller bearing with cylindrical rollers.

Relative to its diameter, the rollers are both thin and long. This kind of roller is called a needle roller. Despite having a small cross-section, the truck center bearing still has a high load bearing capacity, so it is especially suitable for occasions where the radial space is limited. The inclusion of double-row tapered roller bearings and thrust needle roller bearings also belong to the category of needle roller bearings.

The rest of the bearings, such as seated bearings, combined bearings, joint bearings, and other bearings, are special bearings. Although they all have their own merits, their functions are roughly the same.
