ansi ansi  b92.1 tooth thicknes
i have an old book on involute splines that refers to the ansi  standard b92.1-1970. i didn't manage to find it on their web site (not even a new version).
can anybody help me to find it?
in fact i'm looking at some tooth thickness calculations to check some drawings of synchroniser rings. i know the actual tooth thickness (min and max) and i'm looking for the maximum effective thickness.
thanks
the new edition 1996 is available for us $ 95 at
