Curved spring washers, also known as wave washers or Belleville washers, are thin, disc-shaped metal components with a convex or concave curvature. They are designed to provide a controlled preload or spring force when compressed between two surfaces. These washers are often used in mechanical assemblies to adjust, preload, or compensate for dimensional variations.

Here are some key points about curved spring washers:

  1. Materials: They are typically made from spring steel or stainless steel, depending on the application requirements.

  2. Function: When compressed, curved spring washers provide a spring force that can be used to preload bearings, joints, or fasteners. This preload can help reduce vibrations, maintain constant tension, or compensate for wear.

  3. Advantages:

    • They offer a high spring rate compared to other types of springs.
    • They can be stacked in series or parallel to achieve desired preload forces.
    • They are relatively compact and easy to install.

  4. Applications:

    • In precision equipment, to provide consistent preload and minimize variations in performance.
    • In bolted joints, to compensate for dimensional changes due to temperature or loading.
    • In bearings, to preload the bearing and maintain proper contact between the rolling elements and raceways.

  5. Design Considerations:

    • The curvature and thickness of the washer determine its spring rate and preload force.
    • The washer material must be compatible with the environment and resist corrosion.
    • Stacking multiple washers can achieve higher preload forces, but also increases the overall height.

  6. Installation: Curved spring washers are installed between two flat surfaces, typically by placing them under a bolt head or nut. As the bolt is tightened, the washer is compressed, providing the desired preload force.

It's important to note that curved spring washers should be used with caution and according to the manufacturer's recommendations to ensure proper performance and prevent damage to the assembly.
