Helical springsMaterials necessary for every aspect of daily life. Helical spring is a spring that is subjected to torsional deformation, and its working part is also tightly wound into a helical shape. Its characteristic line is linear, can make compression spring, stretch spring and torsion spring. When the load is large and the radial size is limited, two compression springs with different diameters can be used together to become a combination spring. The total winding number n1 is the sum of the effective winding number n and the supporting winding number n2.
Volute coil helical spring can store more energy and bear more load, but the manufacturing process is more complicated. The performance of the concave spiral spring is similar to that of the conical spiral spring.
1. The helical spring can be divided into compression, tension and torsion according to the characteristics of the load at work;
2. According to the structure characteristics, it can be divided into two categories: cylindrical helical spring and variable diameter helical spring; The variable diameter helical spring mainly bears compression load.
3. According to its shape characteristics, it can be divided into conical shape, vortex shape, concave shape and convex shape.
4. In the production and use, the spiral spring can be divided into two categories according to the forming method and material diameter: large spiral spring and small spiral spring; The former is usually formed by heat, the latter by cold.
5. Other categories
There are many types of spiral spring, which can be divided into:Ordinary cylindrical helical spring; Variable diameter spiral spring.
It can be divided into:Sinistral spring; Right handed spring.Variable diameter helical spring is divided into: conical helical spring, volute helical spring, concave helical spring.
Cylindrical spiral spring, simple structure, easy to manufacture, the most widely used. Its characteristic line is linear, can make compression spring, stretch spring and torsion spring. When the load is large and the radial size is limited, two compression springs with different diameters can be used together to become a combination spring.
