According to the different characteristics of the load under operation, helical springs can be categorized into three types: compression, tension, and torsion.

2. Based on structural characteristics, they can be divided into two main categories: cylindrical helical springs and variable-section helical springs; variable-section helical springs primarily bear compressive loads.

3. They can be categorized into conical, spiral, middle concave, and middle convex shapes based on their distinctive shapes.

4. In terms of production and usage, helical springs can be categorized into two types based on the forming method and the diameter of the material: large helical springs and small helical springs. The former is typically hot-formed, while the latter is cold-formed.

5. Other Categories

A wide variety of helical springs exist, which can be categorized by their外形.

Left-Handed Spring

Right-handed helical spring.

Variable diameter helical springs are categorized into: conical helical springs, helical springs with involute grooves, and concave helical springs.

Cylindrical helical springs feature a simple structure, ease of manufacturing, and wide applications. Their characteristic line is linear, making them suitable for compression, tension, and torsion springs. When dealing with large loads and limited radial dimensions, two compression springs of different diameters can be nested together for use, forming a composite spring.
