Rectangular Wire Spring Design

A rectangular spring is a compression spring that is formed in an oval shape as opposed to a cylindrical shape as most compression springs are.

Rectangular wire spring design.

Helical springs are generally made from round wire. Rectangular wire compression springs. Both ends supported beam 6. Design of a cold coiled helical spring made from rectangular section wire subjected to a static or infrequently varying load.

Our stock compression springs are all cylindrical and made out of round stainless steel or music wire. Die spring characteristics century spring has designed and manufactures a complete line of industrial die springs. Compression spring design resources rectangular material. Torsion spring design theory.

If the pitch of the spring is too high the spring could reach a point where the stress is beyond what the material can withstand and it will yield to the force taking a permanent set. Coil springs spiral 5. Rectangular wire torsion springs have higher energy storage capacities than similar round wire springs. Specializing in fine diameter non standard cross section and specialty material wire.

The wire itself is subjected. Square or rectangular wire reacts to the same stress but the distribution of that stress is not as uniform and predictable as round wire. Extension springs straight a. Torsion springs whose ends are rotated in angular deflection offer resistance to externally applied torque.

Torsion springs are stressed in bending. Rectangular wire is employed to reduce the solid height and increase the space efficiency of the design. Manufactured to tight tolerances and stringent quality control standards. Compression springs can also be made in many shapes including barrel conical hourglass or oval.

These springs are commonly referred to as die springs. A helical spring is a spiral wound wire with a constant coil diameter and uniform pitch. Rectangular wire torsion springs. It is comparatively rare for springs to be made from square or rectangular sections.

Compression spring design compression springs apply a force by compressing or pushing on them. The space available permits a maximum outside dia d o i d m of 25 5 mm and a rod of 14 mm should pass freely inside the spring in fitment. Rectangular wire is more efficient in bending than round wire but due to the premium cost of rectangular wire round wire is preferred. In applications where space is limited and particularly where solid height is restricted springs designed from rectangular or keystoned wire are often selected.

The general comments on round wire torsion springs apply to springs with rectangular wire. The most common form of helical spring is the compression spring but tension springs are also widely used. A compression spring is required to meet a load f 1 530 n at l 1 55 mm and f 2 1 060 n at ls 45 mm. The wire can be also be square rectangular or.
