What are conical washers used for?

What are conical washers used for?

They are also called Belleville or conical spring washers. 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.

Can you reuse a conical washer?

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.

How do conical washers work?

Belleville disc spring washers feature a conically shaped disc form. Conical spring washers maintain a high degree of tension and act as shock absorbers on vibrating parts, which keeps assemblies tight. These Belleville washers also compensate for thermal expansion and contraction on bolted joints.

Which way do curved washers go?

the curved washers should be placed to follow the curve of the hole, not go against it.

What is a conical spring?

Conical springs are compression springs that derive their name from their distinctive cone shape. The unique conical spring design offers the advantage of a reduced solid height in comparison to straight compression springs. As a result, conical compression springs can provide a near-constant spring rate.

What is a tab washer?

Tab washers are a mechanical locking solution that secure bolted joints using a physical barrier. The washer itself is a thin piece of metal usually rectangular or circular. The tab washer is installed between the bolt head/nut and the mating surface, and the bolted joint is tightened like a regular bolt.

What is a star washer?

Star washers are a specific type of washer designed to increase locking force by resisting torque applied by the nut, preventing it from unscrewing or separating. Featuring either internal or external tabs, star washers offer greater application suitability.

How do Belleville washers work?

How Belleville Washers Work. 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.

Which side of a beveled washer is beveled?

The bevel side of the washer is facing towards the bolt head.

What is the beveled edge of a washer?

Bevel washers have one flat side. This is for connection with the nut and is protection against the wear this component provides. The opposite side of the washer is sloped to accommodate for the unparallel surface of the structural component.

How do conical compression springs work?

Conical springs are basically compression springs coiled in increasing or decreasing outer diameters thus making its shape a cone or tapered one. These springs tend to reduce solid height and provide stability. The slenderness ratio defines whether a spring will bend or buckle during compression/deflection.

Why are conical springs used?

Conical spring design enables each coil to fit within the next coil, which is a major advantage in applications where solid height is limited. Variable force rate (as opposed to the constant force rate of standard compression springs). Greater lateral stability that decreases the risk of buckling.
