What is spiral spring?

- Mar 17, 2018 -

Spiral spring made of spring wire.There are many kinds of coil springs, and they can be divided into ordinary cylindrical coil springs and variable diameter coil springs according to the shape; they can be divided into left-handed springs and right-handed springs according to the spiral direction. Cylindrical coil springs are simple in structure, easy to manufacture and most widely used. Their characteristic lines are straight lines and can be used as compression springs.


 A spiral spring made of spring wire. There are many kinds of coil springs, and they can be divided into ordinary cylindrical coil springs and variable diameter coil springs according to the shape; they can be divided into left-handed springs and right-handed springs according to the spiral direction. Cylindrical coil springs are simple in structure, easy to manufacture and most widely used. Their characteristic lines are straight lines and can be used as compression springs, tension springs and torsion springs. When the load is large and the radial dimension is limited, two compression springs with different diameters can be used together to form a combined spring. Reducing diameter coil springs include conical coil springs, spiral coil springs, and concave coil springs. Tapered coil springs have good cushioning properties and can withstand large loads. Helical coil springs can store more energy and withstand higher loads, but the manufacturing process is more complicated. Concave coil springs are similar in performance to conical coil springs and are used in cushions and mattresses. The surface of the spring steel wire has round and rectangular shapes, and the circular cross section is most commonly used.


Coil spring, Torsion spring, is a spring that is subjected to torsional deformation, and its working portion is also wound tightly into a spiral shape. The end structure of the torsion spring is a torsion arm that is machined into various shapes instead of a hook. Torsion springs are often used in mechanical balance mechanisms and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.
