Do Belleville washers work?

Do Belleville washers work?

In addition to handling heavy loads, Belleville washers are able to absorb vibrations. Belleville washers are suitable for all applications. But their canonical shape and spring-like characteristics make them ideal for handling heavy loads and absorbing vibrations.

Where are Belleville washers used?

Belleville washers are typically used in conditions of high current loading or cycling. They are used to absorb vibration and can maintain preload in bolted joints, indicating correct preload based on the gap between adjacent washers. They can also help with “bolt creep” or stress relaxation between a bolt and washer.

How do I choose a Belleville washing machine?

A single Belleville Washer has a specific load for a given deflection. Two washers stacked in parallel will yield double the load of a single washer for the same deflection; three washers will yield triple the load; four washers will yield four times the load, etc.

Can Belleville washers be reused?

Yes, Belleville conical washers can be reused, repeatedly, as long as they are not damaged. Overloading and over-torquing these washers can wear them out over time. As long as they are used properly and checked before reuse, these fasteners can be used again and again to complete projects.

Why is it called a Belleville washer?

The “Belleville” name comes from the inventor Julien Belleville who in Dunkerque, France, in 1867 patented a spring design which already contained the principle of the disc spring. The real inventor of Belleville washers is unknown. Through the years, many profiles for disc springs have been developed.

What type of lock washer is best?

We found that the most effective anti-vibration solutions are anaerobic adhesives and mechanical washers. Overall, Nordlock washers were extremely effective. They’re as easy to install as any standard washer—and easier to install than the next-best contender, the Loctite 2760 adhesive.

What is a wavy washer used for?

Wave washers, also referred to as wave springs, are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. Many design variations have evolved to best serve these basic functions.

What is a cup washer?

A cup washer is a type of spring washer formed with a semispherical shaped bottom and/or beveled edge. Cupped washers are also referred to as beveled, terminal washers, flanged cup washers, and retainer washers.

Where is Belleville spring used?

Belleville disc springs are primarily used in applications that require an extremely high amount of force over a small deflection. In many cases Belleville springs are used to replace coil springs where space is limited, a higher force is required, or the size of the system needs to be reduced.

Should Belleville washers be flattened?

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

What material are Belleville washers made of?

DIN Belleville Disc Washers are made with 51CrV4 spring steel (AISI 6150) and finished with a phosphate and oil surface for general protection from corrosion.

What can you do with a belleville washer?

A Belleville washer, also known as a Belleville spring washer or conical washer, is used to distribute the load of a threaded fastener. It can also be used as a spacer, spring, shim, locking device, or for reinforcing and to reduce vibration.

Who are the manufacturers of belleville spring washers?

Solon is an American manufacturer of Belleville spring washers designed to create tight connections better than conventional springs and maintain bolt preload. Some of the applications for Belleville springs and washers include: Live loading; Pump and valve manufacturing; Industrial automation

What makes a belleville washer a landmine?

The characteristics of the Belleville washer make it useful in landmines. Once the spring has been stepped on by a person or a vehicle, the pressure exerted causes the trigger to flip the adjacent firing pin that is connected to a detonator.

What are the different groups of Din Belleville disc washers?

DIN Belleville Disc Washer Series designs are classified into three groups based on the material thickness: Group 1 – This range applies to disc spring washers with material thickness less than 1.25mm.
