Torsion Spring Loading Direction
Torsion Spring Loading Direction
(OP)
Hello all,
Can anyone tell me why torsion springs are always installed such that the applied load closes the coil, rather than opens the coil? Phrased differently: what would be the danger in designing a spring that opposes a force in the "unwinding" direction?
Thanks in advance.
Nate

When the spring wire is coiled from straight wire to the round shape the wire at the outer side of the spring is stretched permanently. Due to the springback property of the wire, the wire "wants" to return to its previous un stretched condition. This causes compressive stress inside the wire at the outer diameter of the spring. On the other hand, in the other side of the wire, in the inside diameter or the spring the residual stress is tensile stress.
