Frequently Asked Questions (FAQs)
1. What are Belleville washers used for?
Belleville washers are commonly used to address issues related to vibration, thermal expansion, relaxation, and bolt creep. They are particularly useful in various industries and applications. These washers are typically made from 300 Series Stainless Steel.
2. What is the difference between a flat washer and a Belleville washer?
Unlike flat washers, Belleville washers are designed to absorb vibrations and shocks, making them crucial in many applications and industries. When used properly, these conical washers can be reused multiple times in different projects, but it's important to avoid overloading and over-torquing them.
3. How many times can you use a Belleville washer?
Belleville washers can be reused multiple times, as long as they remain undamaged. However, excessive overloading and over-torquing can lead to wear and reduce their lifespan over time.
4. What is the difference between coil springs and Belleville washers?
Belleville washers, also known as disc springs, have a conical shape similar to a washer. Compared to coil springs, Belleville washers are smaller in size but can handle much larger loads relative to their deflection rate. The choice between these two types of springs depends on the specific application and requires careful consideration.
5. Do you use a flat washer with a Belleville washer?
In some cases where heavy loads need to be supported, adding a flat washer can enhance the effectiveness of a Belleville washer or disc spring by distributing the load. Additionally, in certain applications, a flat washer can prevent a Belleville washer or disc spring from digging into softer metals.
6. Can you flatten a Belleville washer?
In certain Belleville washer applications, the manufacturer may recommend flattening the washer and then slightly loosening it. However, it is crucial not to loosen it too much, as flattening the washer a second time will result in reduced clamping force compared to its original design.
