Nested Wave Spring

Product Description

Nested Wave Spring supplier Carbon/stainless steel/17-7PH(SUS631) 

Description:

  1. Nested wave springs are pre-stacked in parallel from one continuous filament of flat wire.
  2. The need to stack individual springs for higher loads is no longer necessary.
  3. Nested springs result in a spring rate that increases proportionally to the number of turns.
  4. They can exert tremendous forces, yet maintain the precision of a circular-grain wave spring.
  5. In many applications, nested wave springs replace belleville springs, particularly in cases where a high but accurate force is needed.

 

Heavy-coil wave springs are also called nested wave springs and stacked wave springs. This kind of spring changes with the number of waves and layers, and the stiffness also changes. It is mainly used for small installation space, which requires a certain stroke and requires It can provide larger load conditions, and in some occasions, it is gradually replacing disc springs and is widely used in various industries. GJP is a professional nested wave spring supplier. We can design and select models according to your requirements, or provide samples and drawings for processing and customization. Please call us for details.

 

Advantages of nested wave springs:

Nested wave 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.

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.
