Long life and precision with torsion springs

摘要

Machined Torsion Springs from Abssac offer a range of advantages to end users. Being machined from a single piece of solid material, they can provide very precise linear deflection rates because they eliminate virtually all residual stresses. In a traditional, wire-wound spring, the spring rate can change over time. Because of repetition, the elastic properties deteriorate, which of course means a massive headache for the end user, who is faced with the problem that no two wound springs are exactly the same in terms of performance. Abssac's machined torsion springs, on the other hand, offer precision elasticity that a wire-wound spring cannot. To give some idea of the improvements possible, most wound torsion springs can achieve at best a linear deflection rate of around 15%, but the machined alternative can easily achieve 10% on rate and can be tuned to +/-2% for the more demanding applications.
