The Electrical Construction & Maintenance describes Belleville washers as disk springs that put pressure on the connection once you have properly clamped down on it with sufficient force. It basically generates clamping pressure, one rendered in a continuous arc pattern.
These washers are used in a bevy of ways and applications. Take a look at some of them:
Keep those bolts tight
Ever wonder why bolts stay airtight? That’s the washer at work. The washer keeps the bolt securely and firmly in place. This prevents movement and looseness in the bolts. As a result, you get an airtight fit.
Saves on space and cost
Washers are thin but that doesn’t seem to get in the way. In fact, the thinness of most washer designs helps make efficient use of the space. The lightweight material also means less loads, which means less costs.
Distribute the weight
Another great thing about washers is that they evenly distribute the weight of fasteners. That means even pressure, as a result. By adding more washers, you can even adjust the load distribution in your assembly.
With some assembly units, you might need to pair up flat washers with Belleville washers to get the job done. This happens when you’re dealing with a softer material. If that’s the case, then you’re likely going to need to use a flat washer so always have some of those handy. However, don’t resort to this if you’re working with a Belleville that’s too big. If you want a tighter fit, don’t make do. Find one that’s just the right size or you could end up compromising connections in your assembly.
Make sure you get quality ones. Shop from a reliable Belleville washer supplier. Look for certifications, experience and product quality to help you decide if it’s the right Belleville washer supplier for your needs.
