Spring washers are a type of washer used in bolted joints to provide a spring force and absorb shock or vibration. They are designed to prevent the loosening of fasteners due to vibration or thermal expansion and contraction. There are several types of spring washers, each with specific characteristics and applications:

  1. Helical Spring Washers: These are the most common type and have a helical cut that allows them to act like a spring. They provide a preload to the fastener, which helps maintain tension in the joint.

  2. Belleville Washers: These are conical-shaped washers that provide a high spring force in a small space. They are often used in applications requiring high load capacity and minimal deflection.

  3. Wave Washers: These washers have a wave-like shape and provide a light spring force. They are used in applications where space is limited and a small amount of preload is needed.

  4. Split Lock Washers: These washers have a split cut that allows them to exert a spring force when compressed. They are commonly used to prevent nuts and bolts from loosening.

  5. Curved Spring Washers: These washers have a curved shape and provide a moderate spring force. They are used in applications where a consistent preload is required.

Applications of Spring Washers:

  • Automotive: To prevent bolts and nuts from loosening due to vibration.

  • Aerospace: In critical joints where maintaining tension is essential.

  • Machinery: To absorb shock and vibration in moving parts.

  • Electronics: To ensure secure connections in electrical components.

Advantages:

  • Prevents Loosening: Helps maintain the tension in bolted joints.

  • Absorbs Shock: Reduces the impact of vibrations and shocks.

  • Compensates for Thermal Expansion: Maintains tension despite temperature changes.
