A helical tension spring is a mechanical component that stores energy and provides resistance when pulled, commonly used in tension applications across various machinery.
A helical tension spring is a coiled mechanical spring designed to operate under tensile loads, where it elongates when force is applied and returns to its original length upon release. It typically features hooks or loops at both ends for attachment, and is engineered to provide linear force-displacement characteristics within its elastic limit. These springs are critical in applications requiring controlled tension, energy absorption, or return force in mechanical assemblies.

Tension springs are designed to operate under pulling forces, elongating when loaded, and typically have hooks for attachment. Compression springs work under pushing forces, shortening when loaded, and often have plain ends. Their load directions and end configurations differ fundamentally.
The spring rate (k) is calculated using the formula: k = (G * d^4) / (8 * D^3 * N), where G is the shear modulus of the material, d is the wire diameter, D is the mean coil diameter, and N is the number of active coils. This determines the force required per unit of elongation.
