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