Principle, function and installation of eccentric screw

Principle, function and installation of eccentric screw

Screws appear in all walks of life, and there are many types and names. An eccentric screw is one of them. It is one of the more screw types used in our automotive industry.

It uses the physics and mathematics principles of the oblique circular rotation of the object and the friction force to gradually tighten the utensils and parts.

So what is the principle of eccentric screw? What are the installation methods? Let's talk today

1.Principle

The eccentric screw is a tool that uses the physics and mathematics principles of the oblique circular rotation of the object and the friction force to gradually tighten the objects and parts.
 
Changing the eccentric screw is for adjustment during positioning, and does not affect safety. There is no problem with the above maintenance operations during four-wheel positioning.
 
If the wheel inclination is beyond the standard range of use, it can only be adjusted by using an eccentric screw, which can ensure that the wheel data is normal and avoid tire wear.

2.Installation way
There are a lot of eccentric screws used in our cars. After we install them, we will not increase the force on the screws below. We just say that the eccentric screws will be thinner than the original screws after you have replaced the eccentric screws. Normally, it will not have much impact after going up.
 
If you encounter a large-scale vibration, the strength of the eccentric screw is of course not as strong as the original screw. After changing the eccentric screw, it has no effect on the shock absorption.
 

If the table top has a negative inclination angle, then move the protruding part of the copper sheet to the outside, the short one that is close to the screw inside, and then tighten it.

3.Function

On the whole, the eccentric screw is to adjust the angle of the car tire. Specifically, it is to adjust the inclination angle and the angle of the left and right wheels. Normally, it must be installed. If it is not installed, the tire will wear out after a long time. A puncture.
 

Due to the deformation of the frame, elevation angle, shock absorber and other components, the inclination angle of the main shaft cannot be corrected, and an adjustable eccentric screw must be installed on the shock absorber to correct the inclination angle.
