Screws appear in all walks of life, and there are many kinds and names of them. Eccentric screw is one of them, which is used more in our automobile industry.
It is a kind of equipment that uses the physical and mathematical principles of the inclined plane circular rotation and friction force of the object to fasten the utensils and mechanical parts step by step.
So what is the principle of eccentric screw? What are the installation methods?
principle
Eccentric screw is a tool that uses the physical and mathematical principles of the inclined plane circular rotation and friction force of the object to fasten the machine parts step by step.
The eccentric screw is used for adjustment when positioning, which does not affect the safety. There is no problem for the above maintenance operation when four-wheel positioning.
If the wheel inclination angle exceeds the standard range, it can only be adjusted by using eccentric screw, which can ensure the normal wheel data and avoid tire wear.
Installation method
Eccentric screws are widely used in our cars. After installation, we will not increase the force on the screws below. We just say that after you replace the eccentric screws, the eccentric screws will be thinner than the original ones. After installation, it will not affect the normal operation.
If there is a large vibration, the strength of the eccentric screw is not as strong as the original screw. The eccentric screw has no effect on shock absorption.
If the table top is inclined and the degree is negative, the protruding part of the copper sheet should be outward, the short one should be close to the screw inside, and then it can be tightened.
effect
On the whole, the eccentric screw is used to adjust the angle of the car tires. Specifically, it is used to adjust the inside and outside inclination angle and fine tune the height of the left and right wheels. If the eccentric screw is used to eat the tires, it must be installed. If it is not installed, the tires will be worn out after a long time, and it is easy to burst.
If the inclination angle of the main shaft cannot be corrected due to the deformation of the frame, elevation angle, shock absorber and other parts, it is necessary to replace the adjustable eccentric screw on the shock absorber to correct the inclination angle.
