Spring (with mechanical parts of elasticity)

A spring is a mechanical part that works with elasticity. Parts made of elastic material in the external force under the action of deformation, remove the external force and then restitution after removal of an external force. Generally made of spring steel (72B, 82B, 65Mn, 60Si2mn, 55crsi, oil quenched steel wire), spring manufacturing materials should generally have a high elastic limit, fatigue limit, impact toughness and good heat treatment performance.

Spring manufacturing materials should generally have a high elastic limit, fatigue limit, impact toughness and good heat treatment performance.

According to the nature of the force, the spring can be divided into:

1, Tension spring

The tension spring is a coil spring that receives axial tension. In the absence of load, the tension spring between the circle and the circle are generally tight and no gap.

2, Torsion spring

Torsion spring, is to withstand the torsion of the deformation of the spring, its working part is also closely wound into a spiral. Torsion spring end structure is processed into various shapes of the torsion arm, not the hook ring. Torsion spring using the principle of leverage, through the material soft, toughness of the elastic material twisted or rotated, so that it has great mechanical energy.

3, Compression spring

Compression spring is to bear the axial pressure of the coil spring, which uses the material section is mostly round, but also useful rectangular and multi-strand steel system, the spring is generally equal to the pitch, the shape of the compression springs are: cylindrical, Conical, convex and concave and a small amount of non-circular, etc., compression spring between the circle and the circle will have a certain gap, when the external load when the spring shrinkage deformation, storage deformation energy.

Progressive spring, this spring with a thickness, dense inconsistent design, the advantage is that when the pressure is not large through the lower part of the elasticity of the absorption of the ups and downs of the road to ensure that ride comfort, when the pressure increased to a certain extent After the thick part of the spring to play the role of supporting the body, and the shortcomings of this spring is not easy to control the control, the accuracy is poor.
