Are Belleville washers reusable?

Are Belleville washers reusable?

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.

What is the purpose of a Belleville spring?

The purpose of a Belleville washer is to absorb loads by acting as a spring. When a load is applied a Belleville washer, the washer compresses. At the same time, the Belleville washer exerts an equal amount of force against the object.

Why 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.

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 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 type of spring is a Belleville?

Belleville spring, disc spring, and conical compression washer are all names for the same type of spring. A Belleville spring is a conical shaped disc that will deflect (flatten) at a given rate. This spring rate is usually very high, allowing the spring to produce very large loads in a very small space.

Can 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.

Should Belleville washers be flattened?

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.

Who are the manufacturers of Belleville springs washers?

Belleville Springs Ltd. Belleville Springs has been trading in the spring industry for over 20 years and is a leading UK manufacturer and stockist of disc springs and belleville washers.

What can you do with Belleville flange washers?

Belleville Flange Washers for heat exchangers, high temperature and cryogenic flange bolting. Live loading and ball seat springs, seat locking rings, ball seat, body gaskets and spacers. Belleville disc springs and components for shock tools, jar tools, and drilling motors. Heavy Machinery, Steel Mill, Aerospace applications and much more.

What kind of steel is Belleville washer made of?

Belleville washers, manufactured from steel strip, are not scragged (pre-stressed) during the manufacturing process and the inside and outside diameters of the disc spring are not machined. The usual protective surface treatment is phosphate and oiled.

What kind of springs do Belleville springs use?

Belleville washers are the economical option. Specifically designed to preload roller bearings, with dimensions to suit most standard bearings. With a slotted inside profile to give a different force/deflection profile. Chrome-nickel alloy commonly used for corrosion resistant disc springs at thicknesses up to 1.25mm.
