Working principle of tension spring

Abbreviated as tension spring, also known as tension spring, it is a spiral spring that bears axial tension. Tension springs are generally produced from circular cross-section raw materials. When not under load, the coils of the tension spring are generally tightly connected without any gap between them. There is a type of spiral tension spring, which is generally of equal pitch and has a circular cross-section. They can be used in many occasions, such as production, manufacturing, assembly, experimentation, product development, and maintenance.
Many different terminal devices or hooks are used to ensure the source of tension for the tension spring. The working principle of a tension spring is opposite to that of a compression spring. Compression springs have a reverse effect when compressed, while tension springs have a reverse effect when extended or pulled apart.
When the two ends of the tension spring are pulled apart, the spring will attempt to pull them back together. Like compression springs, tension springs absorb and store energy. But unlike compression springs, most tension springs are generally under the necessary horizontal tension, even without any load. This type of initial tension determines the tightness level of the tension spring coil in the absence of any load.
