ANSI B92.1-1970

[blckwtr]

I am in desperate need to find dimensions on the following three splines:

-- Internal AND external Involute Spline
Fillet Side Root Fit
Class 6
P40/80 Pitch 30° P.A. 23 Teeth

-- Internal Involute Spline
Fillet Side Root Fit
Class 6
P20/40 Pitch 30° P.A. 28 Teeth

Can anyone provide me with a drawing of the spline?

Thanks...
