OTT-JAKOBspringAn elastic element made of metal or heavy plastic in the form of a coiled or small loop of a round line or rope wrapped around a cylinder. Depending on the application in which the coil spring is manufactured, the coil spring can be wound in a loose or tight spiral shape.

Coil springs of different sizes are used to reduce impact and pressure on the surface by allowing additional yield. When an external force is applied to them, they change shape, but when the external force is removed, they return to their original shape. When the spring returns to its normal shape, the energy of the coil spring is stored and restored, depending on the amount of force applied.

Helical springs come in a variety of sizes and shapes, including volute springs, curved springs, bell springs, constant force springs, conical springs, hourglass springs, barrel springs and helical springs. The most common type of coil spring is the compression spring. They are produced using hot or cold winding, and both types are formed on a mandrel, mandrel or cylinder.

Rust and environmental factors can put pressure on coil springs, leading to early failure. For added protection, they are coated with powder, epoxy or polyester, and some are plated with zinc or nickel.

Springs can be helical or non-helical, depending on their design. Coil springs have a coiled appearance and are made of a single strand of metal that forms a coil along the spiral path. The most common way to make coil springs is to wrap wires of different diameters around a mandrel, mandrel, or cylindrical tube. Each type of coil spring has characteristics that distinguish it from the others. The general rule of helical springs is that they are designed to withstand some form of stress, which can be compression or tension.

Circular spiral spring

The curved coil spring, also known as the bow spring, has a bow shape and does not extend straight from the beginning to the end, but has a curve in the middle and is bow, which is used for bows and arrows. They were originally designed for dual-mass flywheels in drivetrains. A force is applied to both ends of the spring to pull objects together.

Variable helical spring

Variable coil springs have different distances between spring rings. The change in the distance between turns changes the compression of the spring at each turn. When a variable coil spring is compressed, the number of pounds of energy changes with each compression or in an exponential curve. The variable spring design makes unlocking easier, and recoil energy storage, damping, loading, guzzling, and locking are all improved.

Torsion helical spring

A torsional coil spring is a flat coil used to apply torque or store rotational energy. They store and release rotational energy through torque, which causes the spring to rotate around its axis to apply or resist a load. A torsion spring is attached to a component that will rotate about its axis. In most cases, they are wound very tightly, but there are also versions with pitch to reduce friction between the coils.

Compression spring

Compression coil springs are coiled in a spiral to resist axially applied forces. They are a very powerful spring and are available in a variety of sizes, from springs for retractable pens to springs for automotive suspension systems. Compression springs come in many types, including spiral, conical or volute, barrel and hourglass.

Tension spring

A tension spring is similar to a compression spring, but is tightly wound and subjected to tension. They have hooks or loops at both ends to apply tension. Both ends of the stretch spring are connected to the assembly. When the components separate, the stretching spring tries to put them back together. The initial tension of the spring determines its degree of winding and can be changed according to the needs of the application. Tension springs are tightly wound to combat tension. Essentially, they provide a return force to parts that have been extended to the actuating position.
