Belleville Washer Application Guide

In a belleville washer application the manufacturer may say to flatten the washer and then back off slightly.

Belleville washer application guide.

The spring rate of a belleville depends on geometry material and loading conditions. Applications of disc springs and belleville springs disc spring to quick action stop valves. The belleville washer has been widely known because of properties that make it stand out among others. Their conical configuration enables them to support high loads with relatively small deflections and solid heights compared to helical springs.

Offering a design that allows for very high load capacity relative to deflection and available space within the application american belleville washers can be specified using limitless dimensional configurations and load deflection ratings. A belleville washer is a type of spring shaped like a washer. 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. High quality belleville spring washers.

Belleville disc spring washers high loads in small spaces when your compression spring application requires a high load in small spaces lee spring s belleville disc washers can be the solution. It is the frusto conical shape that gives the washer its characteristic spring. A plot of load versus deflection will show that the belleville s characteristic curve is linear up. Belleville spring material finishing guide solon established in 1949 solon manufacturing co.

The characteristic curve of a belleville washer makes it possible to be used in various combinations with the necessary support that an application needs. Crown height actually should not exceed 40 of material thickness. In a belleville washer the ratio of material thickness to rim width is held to about one in five. Whether the belleville washer needs to fit tightly under the head of the bolt or provide a wide bearing surface across the mating flange our products offer long fatigue life predictable and consistent.

Finally flange washers are manufactured as standard in steel. Equally they are pieces capable of providing higher loads than belleville springs. A belleville washer is a type of non flat washer and has a slight conical shape which gives the washer a spring characteristic. The belleville name comes from the inventor julien belleville who in dunkerque france in 1867 patented a spring design which alread.

They are often used to solve vibration thermal expansion relaxation and bolt creep problems. Because of its annular shape it is able to force transmission. In application yield strength is not exceeded and the washer returns to its full crown height when compression force is removed. Other washers have limitations when carrying a load unlike the belleville washers that can support large loads even with small insulation space.

Belleville washers provide a very high spring force for short movement and have a high energy storage capacity. These include the following. Make sure you don t back off too far because when you flatten the washer a second time it will have less clamping force than it was designed to have.
