SAE Standard Straight Sided Splines

[mtipg]

Hello All;

I have a question about SAE Standard Splines. In my Machinery Handbook (27th Edition), pages 2184-2185 provide the dimensions and tolerances of the "Hub portion" for three different classes of splines(Permanent, slide no load, and slide with load). I am confused as to dimensions and tolerances for the shaft portion as they are not provided as far as I can tell. Any insight would be a huge help, thanks.

I have tried internet searches and asked a few old classmates about it, but I haven't received an answer as of yet. I am sure there is an easy explanation to this, but I just don't have the resources unfortunately to figure it out. I will post the answer if I get anywhere though.

this requirement was based on the Fed H28 handbook.
the version I have access is 1978 version.
Section 17.

It states that this version is now obsolete and should not be used. how ever the second paragraph states that the shaft dimensions depends upon the shape, and type of material, heat treatment, method of machining to give the required fit.

New designs should use ANSI B92.1 involute splines

It seems to me that it was upto the Engineer to specify
type of steel, Heat Treat, & FIT.
