Most industrial equipment and materials have a complex set of components that require heavily secured bolts to function. Once the bolts loosen, the equipment and materials can be damaged, which could even result in accidents. To prevent accidents from happening, different tools and devices have been produced to tighten different kinds of bolts.

One of the tools that can help tighten the bolts is washers. A washer is a thin plate that supplies friction to the bolt. It also distributes the bolted joint’s load so that the equipment can withstand the involved force. A washer can have different styles that can suit any needs of equipment or material, one of which is the spring washers.

What is a spring washer?

A spring washer, or disc springs, is a small plate that is primarily used in small machines. This washer has axial flexibility that prevents bolts from fastening or loosening due to vibrations. The pre-deflected shape of this washer makes it effective in eradicating rattle, maintaining assembly tension, balancing material expansion or contraction, absorbing intermittent shocks loads, and providing controlled reaction under dynamic loads.

Spring washers are made of steel, copper alloys, or nickel-chrome alloys. Steel is the most common used material for spring washers because of its durability and ease of production. Copper alloys, on the other hand, are non-magnetic, which are useful for equipment and materials that are sensitive to magnetic forces. The nickel-chrome material also has high tensile strength, but is more difficult and expensive to produce than steel spring washers.

How does a spring washer work?

The deflection rate of a spring washer depends on its dimensions and materials. A thinner, shorter spring washer can only sustain a limited amount of load, while a thicker, taller spring washer can hold more. The irregularities of the spring washer flattened out to a certain degree if there’s stress on the equipment or material. This flattening effectively distributes the load between both the bolt and the equipment or material.

Elastic deformation is normal for a spring washer. However, the deflection of the spring washer is irreversible once it is overstressed or comes near the end of its intended use.

What are the uses of a spring washer?

A spring washer is primarily used as a lock for bolts that experience rattles and vibration. If a coil spring is too large for equipment, a spring washer is then used to mitigate vibration. Moreover, another use of spring washer is to prevent pipe flanges from any leaks caused by high temperatures and unstable pressure.

Valves and pumps, braking systems, couplings, machine presses, cable cars, electrical transformers, and others use spring washers as a mitigator to vibration. Even the military, especially army vehicles, use this kind of washers.
