Correct Standard for Specifying Involute Spline Gears

Correct Standard for Specifying Involute Spline Gears

Correct Standard for Specifying Involute Spline Gears

(OP)
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".

RE: Correct Standard for Specifying Involute Spline Gears

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.

RE: Correct Standard for Specifying Involute Spline Gears

What's the tolerance on the helix angle?

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

RE: Correct Standard for Specifying Involute Spline Gears

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.

RE: Correct Standard for Specifying Involute Spline Gears

Should be able to Purchase regardless.
