Belleville Washer Application Guide

They are often used to solve vibration thermal expansion relaxation and bolt creep problems.

Belleville washer application guide.

Belleville washers provide a very high spring force for short movement and have a high energy storage capacity. Their conical configuration enables them to support high loads with relatively small deflections and solid heights compared to helical springs. 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. The belleville name comes from the inventor julien belleville who in dunkerque france in 1867 patented a spring design which alread. Equally they are pieces capable of providing higher loads than belleville springs. Finally flange washers are manufactured as standard in steel.

The spring rate of a belleville depends on geometry material and loading conditions. In application yield strength is not exceeded and the washer returns to its full crown height when compression force is removed. Therefore the maximum fo rce that can be applied to a belleville mainly depends on the limitations of the bolt or joint designs. Designs and manufactures solon belleville springs disc springs din en 16983 din en 16984 and washers that are used in a variety of applications across many different environments.

High quality belleville spring washers. A plot of load versus deflection will show that the belleville s characteristic curve is linear up. The belleville washer has been widely known because of properties that make it stand out among others. A belleville washer is a type of spring shaped like a washer.

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. 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. 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. Applications of disc springs and belleville springs disc spring to quick action stop valves.

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. A belleville washer is a type of non flat washer and has a slight conical shape which gives the washer a spring characteristic. It is the frusto conical shape that gives the washer its characteristic spring. They are especially prepared to bear temperature and or corrosion such as it is commonly necessary in.

Other washers have limitations when carrying a load unlike the belleville washers that can support large loads even with small insulation space. In a belleville washer application the manufacturer may say to flatten the washer and then back off slightly. These include the following.
