♛A Belleville washer, also known as a coned-disc spring, conical spring washer,disc spring, Belleville spring or cupped spring washer, is a conical shell which can be loaded along its axis either statically or dynamically.
♛A Belleville spring washers are especially suited for applications requiring high spring rates in restricted space - they will occupy only a fraction of the compressed height space of a traditional wire spring.
♛A Belleville washer is a type of spring shaped like a washer. It is the frusto-conical shape that gives the washer a spring characteristic.The conical shape applies a spring force against the bottom of the bolt head to help prevent accidental loosening after installation. Belleville washers can be stacked below a bolt head to add more force to the assembly if needed. Conical washers are commonly used in the automotive and machinery industries.
♛Conical Belleville washers are used primarily to add pre-load to a nut and bolt assembly. When placed under the head of the bolt, they add a layer of force between the bolt head and the installation surface. This serves as a resistance to vibration to prevent accidental loosening, which is why these washers are commonly found on automobiles, airplanes, and heavy machinery.
