Flat root side fit
Below talks about Class 2 Fit. (from the Machinery's Handbook 27)
American National Standard Involute Splines*.—These splines or multiple keys are
similar in form to internal and external involute gears. The general practice is to form the
external splines either by hobbing...
I am reviewing an older Spline connection and have a question about the spline class and tolerance.
These were done to ANSI-B92.2M-1980.
Internal Spline:
2 Module
20 Tooth
30° pressure angle
Class 2 Effective Clearances
External Spline:
4H effective clearances
I am not sure what Class 2...
Thanks for the explanation.
One more thing. Can you tell me how to determine the Min thickness of the female spline hub. Or Min Outer Diameter. I want to make the spline as large as possible but I am limited but the OD of the female half of the spline.

I am Looking for some Help with determining the Effective length of a spline but can not find a calculation anywhere. I have the Machinist Hand book Spline section and it has a chart but I seems like there should be a calculation for this.
This is considered a Flexible Spline in the machinist...

Hello to all that have helped.
I have been in contact with A. Slocum who did the calcs on the engineersedge website desertfox directed me to.
This web site has a lot of excel calcs you can down load...
Question for desertfox (Mechanical)
Have you used the www.engineersedge.com/calculators/machine-design/press-fit/press-fit-calculator before?
Do you know what is meant by the inerface diameter (in the outer body parameters)?
and
Do you know what is meant by the Intended outside diameter...
in responce to RB1957:
No we are just using the inner race like a steel bushing. These are very hard and come with thin walls and a large variety. Why do you think this design will have problems?
Thanks,
Kurt
Gentalmen,
This is the application.
I have a steel pin going through a steel housing. the end of the pin is seeing a load that is perpendicular to the axis of the pin and the bore is wearing out. the pin does not rotate or slide in the bore. The addition of the new hardened steel bushing is...
Thanks for the idea of a split bushing. The one in this application is solid and hardened to Rc 58-64. (not sure how the hardness plays into the equation or if it does)
Thanks,
Kurt
Thank you for that i am looking into hoop stress. which leads me to my next question.
In the calculation to determin the pressure between the bushing and the bore there is a variable for the radius after it is pressed into the bore. The book i have is assuming that the bore will move the same...
I am trying to calculate how much a steel bushing that is press fit into a steel housing will shrink on the ID so that i can tolerance the shaft that goes through it properly. I have not had any luck finding this calculation.
Thanks,
Kurt
