elasticity of a belt

elasticity of a belt

(OP)
Hello,

for torsional vibration calculations of installations which use belt drives and pulleys for the distribution of power to different equipment, I sometimes need information on the elasticity of a belt. I realize a belt is not a spring, but I assume it can be represented as such, with an average value representing the stiffness of the belt. Has anyone some information on how to calculate or approach such stiffness?

Regards
rob

RE: elasticity of a belt

rob768,

I have had a lot of difficulty finding information on timing belts lately. I got some answers from thread406-325225: Timing Belt Torque Speed Tables.

Search the website for Stock Drive Products. They have a lot of information up there. If this works out, please buy your timing belts from them. The people who do not want to tell us about their timing belts, should not be making sales to engineers.

rob768,

I have purchased a book from Stock Drive Products. Design and Application of Small Standardized Components, Data Book 757. It is copyright 1983, and I bought it sometime around thirty years ago, and it just helped me work out some timing belts. It is too bad it does not cover more recent timing belt developments, but it might be enough for you to get your job done.

This may still be available, possibly in a more recent edition!
