Main function of coil spring
1 Control the movement of the machine, such as the valve spring in the internal combustion engine, the control spring in the clutch, and the like.
2 Absorb vibration and impact energy, such as shock absorbers under the car, train compartment, and vibration-absorbing springs in the coupling.
3 Storage and output energy as power, such as clock springs, springs in firearms, etc.
4 used as a force measuring component, such as a force detector, a spring in a spring balance, and the like. The ratio of the load to deformation of the spring is called the spring stiffness. The greater the stiffness, the harder the spring.
The spring is a kind of elastic element widely used in the mechanical and electronic industries. When the spring is loaded, it can generate large elastic deformation, transforming mechanical work or kinetic energy into deformation energy, and the deformation of the spring disappears and returns to the original state after unloading. The deformation energy is converted into mechanical work or kinetic energy.
