Planar spiral spring is important for the dimensional miniaturisation of motor-based elastic actuators. However, when the stiffness calculation of the spring arm is based on simple beam bending theory ...

Many mechanical applications take advantage of spiral torsion springs due to their robustness, compactness, and simplicity. Brand-new manufacturing methods allow to create spiral springs with ...

With its piezo-based forming technology, Reell holds spring tolerances to within ±0.0005 in. A piezo-based tool controls spring diameter and compensates for wear in Reell s spring-winding process.
