A wave spring is made from coiled flat wire with waves added to give it a spring effect. Wave springs are superior to coil springs in certain applications because they provide lower work heights with the same force. This not only provides for space savings, but also smaller assemblies that use less materials, hence lower production costs.
Rotor Clip coils pre-tempered flat wire made from rolled round wire as raw material. The on-edge-coiling process creates a circle with one or more turns to specifications in any diameter and any number of specific designed waves.
There are three main types of wave springs.
Advantage of Flat Wire Wave Springs:
- Space saving in axial direction – 50% of the operating height could be reduced
- Bending load in the waves guarantees 100% axial transmission of load
- Only one spring must be handled comparing to stacked disc springs / wave washers
- Space saving in radial direction compared to disc springs
- Single turn wave spring offers "cling in bore” option--spring is fixed and centered by itself
"Cling on shaft” as assembly help option
- Low load tolerance at specified work heights
- More accurate spring rate and loads which could have a tolerance that is 50% tighter than stamped wave washers or disc springs
- Unlimited range of forces could be created by using the factors wire size, wire form, no. of turns, turn configuration, no. of waves and wave form
