    Nice link Fred. I have belt selection books from 2 manufacturers but this online reference is handy.

    I don't get a chance to use belt drives very often. When I do, I like to take a look at that link. Glad you like it.

    Hey Fred, just thought I'd let you know about something I found while poking around in the Machine Design and Analysis package for MathCAD-

    Machine Design and Analysis: Section 1.13- Selecting a V-Belt

    It runs you through the entire process laid out in that website link, from horsepower ratings, to Service factors, etc. Interestingly it also has sections on selecting leather, rubber, or multiple V-belts; along with all of that is timing belts, wire-rope drives, and of course gear trains, bearings and shafts, springs, ... Holy moley it's got a lot in there.
