Multi-layer Wave Spring for Compact Axial Applications
A multi-layer waveform spring is a precision elastic component engineered to deliver significant axial force within minimal space constraints. This innovative design combines multiple wave-shaped spring layers, offering space savings of over 50% compared to conventional helical springs while maintaining comparable load capacity.
Design Architecture and Working Principle
Available in 2, 3, 4, 5 or more layers, these springs can be configured in opposed or stacked arrangements. Stacked configurations increase spring force, while opposed arrangements provide greater deflection. This flexibility gives engineers additional design variables beyond traditional wire diameter and coil length parameters.
