Torsion & Double Torsion Springs Torsion springs often are suited to situations where torque is applied from two directions, as they are designed to offer resistance to externally applied pressures. Torsion refers to the twisting action of the coils, although the wire itself is subjected to bending stresses rather than torsionally applied stresses. These springs perform at a maximum when supported over a tube or rod.
Common Manufacturing Specifications While we have listed some of the most common sizes, materials and manufacturing specifications, Newcomb Spring provides completely customized production on all parts. If you don’t see the part you need listed here, don’t hesitate to contact us. Whatever your needs – Newcomb Kan-Do It!
With ISO 9001 certified quality systems, Newcomb Spring offers eight manufacturing plants and a special facility focused on the needs of our customers in Mexico and Latin America. We are ready to manufacture the precision springs and metal form parts that you need.
As a leading torsion spring manufacturer, our capabilities for these coil springs can fill almost any customer need, from a simple straight leg or a close wound spring to a unique example of a double torsion spring, where one right coil section and one left coil section are connected and work in parallel.
Formulas & Manufacturing Specifications
Winding A torsion spring can be closed- or open-wound and usually is designed to wind up. As a torsion spring winds up, the coil diameter will decrease and the body length will increase. Read more on the direction of spring winding in our technical articles.
Spring Load It is important to consider the direction of loading when designing bends or forms off a spring’s body or in spring legs. Favorable residual stresses can be created when bends are loaded in a direction that reduces the radius or curvature.
Design With new manufacturing techniques, torsion end positions can be held to surprisingly close tolerances. Older-design free angle tolerances often do not apply. Newcomb is a torsion springs manufacturer whose facilities employ modern forming machinery and production techniques that allow for an infinite variety of torsion spring end shapes. When specifications call for very long spring legs, we recommend discussing your requirements with a Newcomb sales engineer. Our staff can verify manufacturing capabilities and will work to keep your production costs as low as possible.
The Affects of Spring Ends & Installation The type of ends and installation affect spring load and deflection, as shown in the diagram, in which Point (A) rotates in an arc about the center of the shaft. All torsion springs have 3 or more points of contact with at least two at the ends and one at the arbor.
