What is Tension Springs?
The tension spring is one of the helical springs, which is a spring that bears axial tension. The characteristic of the extension spring is that when it is not under load, the coils of the extension spring are generally tight and there is no gap.
What is the Difference Between a Compression Spring and a Tension Spring?
The most obvious difference is that there is usually a certain gap between the rings of the compression spring, and the spring will shrink and deform when subjected to an external load.
What is the Difference Between a Tension Spring and a Torsion Spring?
The significant difference between extension springs and torsion springs is the difference in force:
- When the spring is subjected to a pulling force along the axial direction, it is a tension spring, and under the action of the axial force, it generates a reverse elastic force along the axial direction.
- When a spring is subjected to a torque around an axis, it is a torsion spring.
In order to facilitate the application of tension or torsion, the two ends of the spring are often made into a more suitable shape according to the usage.
