Searching for Spline Misalignment Reference
(OP)
Hello all,
I have lost my copy of "How To Evaluate the Effects of Spline Misalignments" by Earle Buckigham, published in Machinery September 1961 pages120-128.
Do any of you kind souls out there have a copy that you can share with me please? I feel like my left arm has been cut off.....
Thanks in advance!

RE: Searching for Spline Misalignment Reference
It is the actual reference paper I am seeking. The challenge for designing for misalignment is not of concern. That is relatively easy. The Machinery handbook does indeed provide a good reference to the tables and formulae we often encounter.
Regarding Dudley's paper; Earle Buckingham takes a very different approach from Dudley in that he addresses the problem of misalignment in mating splines directly. Buckingham thus looks to evaluate the effect of misalignment on each tooth and, by assessing the amount of deformation that occurs in adjacent teeth, is then able to precisely evaluate the exact loading on each individual spline tooth. This approach has demonstrated quite marked improvement in life when used (a factor of 10 and some!). The Dudley method is a good check stress approach for general cases but I have found Buckingham's approach goes the extra mile.
I have had to dig out my prior algorithm recently and was asked to demonstrate/validate the method. Without the reference, I am in a bit of a pickle and hence my reaching out to folks for help.
Thanks again.

It is the Earle Buckingham post from Machinery magazine I need. I have all the Dudley papers.

The NE Regional Depository is located behind the medical college in Rootstown. You could call them and ask what would be the best way to request a copy of the article. Their phone number is 330-325-6400 or e-mail one of their staff members who are listed on the following Web page:

I hope this helps.
RE: Searching for Spline Misalignment Reference
Yes, Dudley. Thanks for the correction gearcutter!
Regardless, the main point in this article that one should note when designing a reliable spline joint subject to misalignment is the extremely conservative design limits for simple flank contact stress. The recommended limit for high strength alloy steels is only about 5ksi.
It is also critical to consider the effect of tooth tip thinning when evaluating the external spline L/D and tip/face crowning. Even a slight amount of tip/face crowning can result in sharp-edged external tooth tips.

@724Napier, no I had no luck obtaining this reference. Ironically, my need has refreshed itself on account of involvement with a new initiative this week. Involute splines keep cropping up wherever I tread. I am beginning to think they are one of the most misunderstood mechanisms in the history of engineering. I would certainly appreciate being able to get a copy from you or anyone out there.
Thanks for everyone's interest on this matter.
Best regards.

As those who have already read it know, it's main subject is crowned gear couplings.
As some have already suggested; it's very dated and somewhat limiting in scope.
For a more modern look at gear couplings; how to evaluate and design them - far more detailed sources of information are available;
* 'Couplings & Joints' by Jon R. Mancuso.
* 'Flexible Couplings: Their Design, Selection and Use' by Michael M. Calistrat; Andrew B. Calistrat
Both books are still available.
Something that's often overlooked with these couplings is the effect that they can have on other parts within the transmission.
Both books deal with these issues.
