In a news report through from US based Smalley Steel Ring Co, they talk about the unique advantages that their Wave Springs (Flat Wire Compression Springs) offer
including space savings when used to replace coil springs. By reducing spring operating height, wave springs also produce a decrease in the spring cavity. With a smaller assembly size and less material used in the manufacturing process, a cost savings is realized.
Wave springs operate as load bearing devices. They take up play and compensate for dimensional variations within assemblies. A virtually unlimited range of forces can be produced whereby loads build either gradually or abruptly to reach a predetermined working height. This establishes a precise spring rate in which load is proportional to deflection.
Pictured is a Smalley wave spring ideal for preloading bearings. The wave spring preloads the bearing through its outer race, taking up play in the bearing. Preloading will reduce bearing damage, wear, noise and vibration. The wave spring prevents sliding between the rolling elements.
A Google search of spring manufacturers in New Zealand did show up a group of manufacturers who supply Flat Wire Compression Springs although their was no specific reference to wave spring terminology.
