A Belleville Washer, also known as a Spring Washer, is a conical shell that can be loaded along its axis either statically or dynamically. A Belleville Washer is a type of spring shaped like a Washer. A Washer is to prevent damage to the surface being fastened. By distributing the load over a larger surface area, the washer helps to prevent the fastener from digging into the surface or causing it to deform. The thickness of a washer can also vary, with thinner washers often used in applications where space is limited.Attributes:• Protect against damage by distributing the load uniformly and reducing the tension on the fastener.• Provide high strength and wear resistance.• Withstand high temperatures without losing their strength or integrity.Applications:A Washer is used to distribute the load of the fastener over a larger area, which helps to prevent damage to the surface being fastened and is used in various systems like Flexible Coupling and in the Flywheel Ring Gear.
