What's Torsion spring?
Torsion springs, whose ends are rotated in angular deflection, offer resistance to externally applied torque. The wire itself is subjected to bending stresses rather than torsional stresses. Springs of this type are usually close wound, reduce in coil diameter, and increase in body length as they are deflected. Special types of torsion springs include double torsion springs, heavy duty torsion springs, and springs having a space between the coils to minimize friction. Double torsion springs consist of one right-hand and one left-hand coil section and working in parallel

How Torsion Springs Work?

Torsion springs are often close wound, so that each coil touches the next. Their ends are configured in different ways. Like extension springs, torsion springs must attach to other parts at both ends in order to work. When forces act on the spring ends, they tighten the coils of the torsion spring. As the spring returns to its resting coil diameter, it brings the attached parts with it.To hold them in place, torsion springs are often placed on a mandrel, a small rod or peg, that fits inside the coils. The fixture must be snug enough to avoid excessive play, but loose enough to allow full motion. Alternatively, the entire spring can be placed in a blind hole to keep it in place. In other cases, as in the clothespin example, the spring ends are configured in such a way that they connect the spring securely to its adjacent parts.Depending on the application, torsion springs can be left hand, right hand or double. The latter configuration is like two springs (left and right hand) coiled from the same wire.
In many cases, torsion springs are often used in equipment that involves large amounts of force. Sudden and unexpected failure can put nearby property, or worse yet, people at risk. For this reason, it is critical that the torsion spring design be appropriate for the job. The best way to assure you get the right torsion spring that will deliver performance, reliability, and safety is to choose a knowledgeable and experienced manufacturer. Zihuoli Spring has over 14 years' experience providing quality torsion springs and custom-made springs for any application.
