Wavy washers

Post by toolroom » Sun May 19, 2019 3:25 pm

I hope this question is in the correct forum, as I have an application to utilize a wavy washer. The posed question is: How does someone determine the tensile strength /compression value of a wavy washer. My 19th Edition machinery's Handbook says nothing about the wavy washers. Does anyone in the forums know how to calculate the compression value of wavy washers? Internet doesn't help much, unless I am searching in the wrong place.
Thanks in advance for any information.

Glenn

Operating machines is perfectly safe......until you forget how dangerous it really is!

You could also try a search for Belleville washers as well. I believe that's the more common industrial name.

All we had to do was look a Glenn's links. A " wavy washer" is a set above regular shimming. If it is the right category and heat responsive, it can do what flat shims can't.

No, wave washers are different. Belleville washers are sort of dome-shaped and flatten out under pressure. They typically have quite a high spring constant. Wave washers are "wavy": alternating high and low areas. They have lower spring constants.
