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.
