The most common way to classify springs is by how load is applied to them. You’re probably familiar with the following:Compression spring: designed to operate with a compressive load and found in shock absorbers, spring mattresses, mechanical pencils, and retractable pens. Extension spring: designed to operate with a tensile load. An archetypical example is a Slinky, but these are also found in luggage scales and garage door mechanisms. Torsion spring: designed to operate with torque (twisting force); powers every clothespin and mouse trap.

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs. Linear springs Linear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and...

In the actual work, we often encounter that the spring cannot push the moving object to the set position, that is to say, the length of the spring's computational freedom becomes shorter.The main reason is that there is no initial compression, that is, a spring is made into a spring, which is compressed to its compression height or to its compression height (if necessary) with a greater force, and cannot be restored to its original free length upon release.Its shortened quantity is called "initial compression quantity".After repeating 3-6 times of compression, the length is no lo...

compression spring is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful also rectangle and multi-strand steel rolled a travelling, spring is usually pitch, such as the shape of the compression spring are: cylindrical, conical, convex and concave and a small amount of noncircular, compression spring there is a certain gap between circle and circle, when under external load spring contraction deformation, deformation energy storage.


The tension spring is a spiral spring that bears the axial tension.When there is no load, the stretch spring is usually closed between the coil and the coil.It is widely used in machines and instruments to control the movement of the parts, to store energy and to measure the force.The hook is made of side hook spring, long hook spring, British hook spring, German type hook spring, half-circle hook spring, duck bill hook spring, etc.


Torsion springs have a great amount of mechanical energy by twisting or rotating a flexible material with a high degree of flexibility and toughness, using the lever principle.The working part of the spring, which is subjected to torsion and deformation, is also enclosed or separated by loops.The end structure of the torsion spring is made into various shape of torsion arm, which can be formed by the design.Torsion spring is often used in mechanical balancing mechanism, which is widely used in automobile, machine tool, electric appliance, etc.

springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its o...
