Wave washers are a fastener accessory used to create a small gap between two surfaces. They get their name from their wave-like shape, which creates a spring force. That’s what makes them excellent shock absorbers.
Wave washers are also known as coiled wave springs or wave springs. But what exactly do they do, and how are they used? In this article, we’ll take a closer look at wave washers and explain everything you need to know about them.
How do Wave Washers Work?
Wave washers work by applying tension or storing energy when under force. When installed between two surfaces, they help prevent the assembly’s disintegration due to vibration or another movement.
The wave-like shape of the washer provides 3, 4, or 6 contact that allows for a small amount of deflection. The result is a greater load-bearing capacity in a compact space. Wave washers also help offset tolerance deviation and prevent loosening due to movements and vibration.
The washers experience axial strain due to load placement, and the material will try to return to its free state. This spring-like action makes wave washers ideal for shock absorption. Additionally, wave washers can act as shims to level machinery or other equipment.
