A helical torsion spring is a wire in the shape of the helix and it is subjected to twisting about the axis of the coil when sideways forces are applied to its ends and result in twisting the coil tighter.
Torsion springs are the helical springs that exert a rotational force (torque). These springs are resistant to the rotationally applied force. A torsion spring works by twisting its ends along its axis.
When twisted this flexible elastic spring stores mechanical energy in it. After getting twisted it exerts torque in the opposite direction, the amount of torque generated is directly proportional to the amount of angle the spring is twisted.
There are certain spring diameters you will need to be sure of so that it fulfills your requirements. These important parameters are –
Length of the spring, wire diameter, inner diameter, and outer diameter. The inner diameter is essential when the torsion spring is required to slip over a mandrel with sufficient clearance to operate freely. It’s essential to know the outer diameter specifications when the torsion spring is required to fit into a circular hole with sufficient exterior clearance to operate freely. The length of the spring is known as the spring coil length.
Uses Of Torsion SpringsSome very common and familiar uses of the torsion springs are the helical torsion springs that are used in the clothespins and traditional mousetraps that look like a spring-loaded bar.
