Design of Double Torsion Springs

Double-bodied torsion springs are designed using the same methods as for single-bodied torsion springs. The rate for a double-bodied torsion spring is equal to the sum of the rates for each component. For the same wire diameter, coil diameter and wire length, double-bodied torsion springs have rates four times those of single-bodied types. Double-bodied torsion springs should be designed so they are coiled out from the center rather than in from the ends.

Preferred Winding For Double-Bodied Torsion Springs

While Newcomb Spring can produce double torsion springs in both the preferred wind and the non-preferred wind body shapes, the preferred configuration lowers production costs.
