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.
