Correct Standard for Specifying Involute Spline Gears 1

[rShell]

I am new to specifying gears. What is the current standard for the control of involute spline gear profiles? ANSI informs me that both B92.1 and B92.2 are "Out of Print".

Zeroth problem: Splines and gears are different things.

The word involute refers to a mathematical curve which is used to describe and generate the face profile of some gears, and of some splines.

Thanks for the education, Mike! Perhaps I should have said "involute spline/gear profiles". Please look at the attached sample drawing. This is an example of the type og callout that I am trying to get the correct specification for.

What's the tolerance on the helix angle?

+/-1deg. Does this affect what specification is referenced?

The helix angle is basic, It would be controled by the profile lead tolerance(tooth parallelism}.

My prefered spec for the USA version ANSIAGMA 2000-A88
Splines ANSI B92.1

follow that format as called out on both.

Should be able to Purchase regardless.
