Rectangular Wire Spring Design
In applications where space is limited and particularly where solid height is restricted springs designed from rectangular or keystoned wire are often selected.
Rectangular wire spring design. Compression spring design resources rectangular material. Torsion springs are stressed in bending. Die spring characteristics century spring has designed and manufactures a complete line of industrial die springs. Specializing in fine diameter non standard cross section and specialty material wire.
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. The wire can be also be square rectangular or. Coil springs spiral 5. Torsion springs whose ends are rotated in angular deflection offer resistance to externally applied torque.
The most common form of helical spring is the compression spring but tension springs are also widely used. 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. These springs are commonly referred to as die springs. Belleville washers disk springs considerations.
Hair springs very light load 8. Compression spring design compression springs apply a force by compressing or pushing on them. In producing springs from rectangular wire the wire cross. Rectangular wire compression springs.
Rectangular wire is employed to reduce the solid height and increase the space efficiency of the design. Design of a cold coiled helical spring made from rectangular section wire subjected to a static or infrequently varying load. 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.
It is comparatively rare for springs to be made from square or rectangular sections. The general comments on round wire torsion springs apply to springs with rectangular wire. Torsion spring design theory. Rectangular wire torsion springs have higher energy storage capacities than similar round wire springs.
Our stock compression springs are all cylindrical and made out of round stainless steel or music wire. Rectangular wire is more efficient in bending than round wire but due to the premium cost of rectangular wire round wire is preferred. 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. Helical springs are generally made from round wire.
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. Extension springs straight a. Rectangular wire torsion springs. Manufactured to tight tolerances and stringent quality control standards.
