Newcomb Spring has torsion spring expertise

Newcomb Spring is an expert when it comes to springs, offering its customers awide range of services in addition to the manufacture of high-quality products —from design assistance when an order is first placed, to specialty packagingwhen it’s shipped.

Torsion springs— used to store rotational energy or to apply torque — are oneof the company’s areas of expertise. A torsion spring can be closed- or open-wound, and is usually designed to wind up.

“It is always best to design torsion springs to wind up in use and to apply force inthe direction of the wind; otherwise, unfavourable bending stresses will occur,” thecompany explains. “As a torsion spring deflects in the direction of the wind, thespring’s diameter will decrease and its body length will increase. In thesesituations, it is recommended that the torsion spring be supported on its innerdiameter (I.D.) with a shaft or tube, sized so that there will be no binding as thetorsion spring deflects.”

Double-torsion springs are a common type of torsion spring. They are made of a左手组件和一个右手组件,which are connected at thecentre. It is possible to have the two components connect at the outside edge,though this is not recommended.

With new manufacturing techniques, torsion end positions can be held tosurprisingly close tolerances. Older design-free angle tolerances often do notapply. Newcomb has modern formingmachinery and production techniques that allow for an infinite variety of torsionspring end shapes, including bent, hooked, twisted and looped, or any customshape required.

Typical material shapes and sizes for torsion springs include: .004 to two inchesin wire diameter, round wire, square wire, rectangular wire and special sectionwire. However, Newcomb Spring can custom manufacture any torsion spring ordouble torsion spring to fit customer needs.

“When specifications call for very long torsion spring legs, we recommenddiscussing your requirements with a Newcomb sales engineer,” the companysays. “Our staff can verify manufacturing capabilities and will work to keep yourproduction costs as low as possible.”
