Nested wave springs are legal linear wave springs with multiple turns, coiled in parallel to create higher forces. These forces increase proportionally to the number of turns. They can replace stacked single-turn wave springs when the application requires higher loads than a single-turn can produce.
Nested wave springs can provide higher loads than single-coil springs. While disc springs can also handle higher loads, nested wave springs take up less radial space and can handle higher loads. They also simplify assembly, requiring only one part, as users do not need to stack like single-turn designs, stampings, or disc springs.
Nested wave springs have high reliability, excellent performance, no deformation, smooth surface, no pits, scratches, breaks and other small defects. Stamped wave springs may have defects such as fatigue fracture and inaccurate load in the subsequent manufacturing process. In terms of metallurgy, mechanical properties and dimensional stability, wave springs can provide precision quality.
The force value of the nested wave spring is proportional to the number of turns. It can maintain all the properties of the wave spring while deforming. In many occasions, the nested wave spring can be used instead of the disc spring.
Advantages of Nested Wave Springs:
1. Nested springs have multiple turns, coiled in parallel to generate more force. Wave springs of this type are designed to produce very high spring forces compared to standard single coil springs. Nested springs are primarily used in the automotive, oil and gas, and connector industries. They can be found in a variety of applications, such as seals and valves, and can be used to preload bearings. Nested wave springs are available when your application requires more force. The nested wave spring force increases proportionally to the number of turns of the coil. Compressing a wave spring creates bending or tensile stress, which limits the amount of force the spring can produce without failing or permanently deforming. It is recommended that the calculated working stress be less than the minimum tensile strength of the material in static applications and less than 80% of the minimum tensile strength in dynamic applications. Stacked single-coil springs allow for higher loads while distributing the stress evenly across the part. A nested spring provides the required load without stacking multiple parts.
2. Uneven load caused by dislocation during installation, please use nested wave spring. Consider using nested springs when the desired load requires stacking multiple single-coil springs in an assembly. The gaps in the stacked single-coil springs must be aligned to prevent uneven force or loading during compression. Unlike stacks, nested wave springs are single, continuous flat wires that ensure multiple layers remain aligned for consistent loading.
3. When you want simple and cost-effective production, consider using nested wave springs. Unlike stacks of single-coil springs that need to be installed individually to ensure repeatability, nested springs are individual parts that fit directly into the housing. This approach simplifies and speeds up installation, saving time and money.
4. When using automatic handling during assembly, select nested wave springs. Other types of springs may be deformed by the robotic arm during pick and place, or may become tangled when placed into the hopper for vibratory sorting and feeding. This results in wasted time as parts must be sorted and assembled by hand. Nested springs are ideal for automated processes because they have no floating ends and the coils sit tightly together, preventing tangling. The nested multi-turn configuration ensures that multiple layers remain aligned for consistent loading. The wave spring design is also strong, making it ideal for easy pick-and-place installation.
5. Customize nested wave springs to meet your application requirements. Nested springs can be made with almost any number of turns to achieve the desired spring force. Materials, dimensions and required loads are just some of the spring characteristics that can be customized. Each application has its own specific requirements and it is recommended to speak with an engineer before specifying custom components. When solving unique application challenges, experienced spring engineers can provide the best solution. Nested wave springs are an important part of consideration when your application requires high spring forces or stacking of single coil springs.
