Varieties of Overlap Wave Spring

Overlap wave springs, or nested wave springs, come in a variety of designs and configurations to meet different application requirements. Here are some of the common varieties of overlap wave springs:

1. Standard Overlap Wave Spring:
   • This is the most basic type of overlap wave spring, consisting of multiple wave elements stacked on top of each other in an overlapping pattern.
   • Standard overlap wave springs can be customized in terms of material, number of wave elements, dimensions, and other parameters.
2. Tapered Overlap Wave Spring:
   • Tapered overlap wave springs have a gradually changing thickness or diameter from one end to the other.
   • This design allows for a variable spring rate, where the force per unit deflection changes along the length of the spring.
   • Tapered overlap wave springs are useful in applications where a specific force-deflection curve is required.
3. Bellows Overlap Wave Spring:
   • Bellows overlap wave springs have a corrugated or accordion-like shape.
   • They provide additional flexibility and compliance compared to standard overlap wave springs.
   • Bellows overlap wave springs are often used in applications where high flexibility and low spring rates are needed.
4. Precision Overlap Wave Spring:
   • Precision overlap wave springs are manufactured with tighter tolerances and higher-grade materials to ensure greater accuracy and repeatability.
   • They are used in precision mechanical devices and applications where precise force and deflection control is critical.
5. Material Varieties:
   • Overlap wave springs can be made from various materials, including stainless steel, carbon steel, beryllium copper, and other alloys.
   • The choice of material depends on the application requirements, such as corrosion resistance, temperature range, and strength.
6. Coating and Surface Treatments:
   • Overlap wave springs can be coated or treated with various finishes to improve their performance.
   • Coatings and treatments can enhance corrosion resistance, wear resistance, or lubricity.

It's important to note that the specific variety of overlap wave spring needed depends on the requirements of the application. Consulting with a spring manufacturer or supplier can help determine the best type of overlap wave spring for a particular use case.
