What Is a Belleville Washer?
A Belleville washer is a type of spring that’s shaped like a washer. It is also sometimes known as a disc spring, Belleville spring, coned-disc spring, conical spring washer, or cupped spring washer. It is a disk spring that applies pressure to the connection once you clamp down on it with the proper amount of force. The advantage of this washer is that it applies to clamp pressure along with a continuous arc pattern, instead of concentrating it at one point like a split-ring lock washer. These washers are known to help minimize vibration, thermal expansion, relaxation, and bolt creep problems.
Why Is It Called a Belleville Washer?
The Belleville washer is named after its founder, Julian F. Belleville. He designed these discs to take on heavy steel weights. Belleville designed the washer to be a spring as well. Though canonical-shaped washers had been around for several decades prior, Julien Belleville filed a patent for a cupped, spring washer during the 1860s in France. Belleville washers have since become a popular choice for high-stress applications requiring the use of a washer.
How Do Belleville Washers Work?
The purpose of a Belleville washer is to absorb weight by acting as a spring. When you apply a load to a Belleville washer, it compresses the washer. At the same time, the Belleville washer exerts an equal amount of force against the object. To use a Belleville washer, place the washer so its cup points toward the connection, away from the bold head. Mount the washer upside down, which adds clamping force to the connection. It is common to incorrectly place a Belleville washer.
Where Can You Use American Belleville Washers, and Can You Reuse Them?
Vibrations can often knock conventional washers loose. However, this isn’t a problem with Belleville washers because of their canonical shape. Many vehicles, for example, use Belleville washers to decrease vibrating. Some other industries that use these washers include:
- Electrical connections
- Industrial equipment
- Oil and gas
- Aerospace
- Manufacturing
- Medical equipment
- And more!
Plus, as long as there are no signs of significant wear or damage, you can reuse Belleville washers.
