Wave Washer
A wave washer, also known as a wave spring, is a unique type of washer characterized by its wavy or curved shape. Unlike a flat washer, it's designed to function as a spring, providing a continuous force within an assembly. This spring-like action allows it to absorb shock, reduce vibration, and compensate for small variations in component dimensions or thermal expansion. Wave washers are particularly useful in applications where axial space is limited, such as in bearing preloading or taking up slack in an assembly to maintain a tight fit.
When a wave washer is compressed between two components, its wavy form flattens slightly, generating an elastic force that pushes back on the parts. This continuous pressure helps prevent components from loosening due to vibration and ensures a constant load is applied. They are an excellent solution for tasks like cushioning light loads and maintaining a secure connection in various industries, including automotive, aerospace, and electronics.
