Torsion Spring Component Generator

The calculation is used for designing and checking helical torsion springs manufactured from a cold-formed wire or rod with a circular cross-section.

Calculates plain torsion with a correction for additional bending. It uses four basic spring states:

Free	The spring is not loaded (index 0).
Preloaded	Smallest working load is applied to the spring index (index 1).
Fully loaded	Maximum working load is applied to the spring (index 8).
Limit	The spring is deflected to the solid length (index 9).

The Calculation tab has: design and check. During spring design, the wire diameter, number of coils, and spring free length L0 are designed for a specific load, assembly dimensions (j1, j8, jH) or for the spring diameter and material. In the check mode, assembly dimensions or spring loads are calculated for the specific spring.

In the Torsion Spring Component Generator:

• On the Design tab, set parameters for a torsion spring design such as the wire diameter or arm type.
• On the Calculation tab, set parameters for calculation of a torsion spring, loads or spring materials for example.

Tip: The calculation procedure is described in the Engineer's Handbook for both modes and for the calculation in metric and English units. You also find other instructions for designing torsion springs in it.
