dimension between pins
dimension between pins
(OP)
i don't have much experience with splines so i was wondering if anyone can help me with understanding the formulas for calculating the dimension between pins for a 30 degree flat root side fit 14 tooth 12/24 internal spline. i'm not sure how to calculate the pressure angle at pin center mostly. thanks in advance
fyi, i do have ANSI B92.1 in front of me on page 96

RE: dimension between pins
I do not have that standard on hand, but as far as I know, you should be able to calculate the
inv(of the pressure angle at the pin center)
From it the pressure angle can be calculated.

the calcs are the same I use the same program I wrote to verify splines or gears.

If this is a one time issue it's easier just to use software all ready written.
if you still need more info
This is a good book to start with Spur & Helical gear problems. Invo spline Company.if you can find it ?
RE: dimension between pins
I also have couple of my calculations for the over/between pins/balls and . In VB, as a spreadsheet, as a htm file (javascript).
I agree that using a ready made calculation is OK, but I also believe that to understand how the formulas work and what they geomtrically mean is very important.
RFACATguy can learn a lot doing his own calculation "from scratch".

From ANSI B92.1-1996, page 104:
measurement between 0.1440 dia pins for max actual space width on a class 5, 14 tooth, 12/24 pitch, internal involute spline: 0.9609 inch.
A few years ago, a company called Van Keuren that makes gauge wires published a very nice reference book that gave you hundreds of tables for over/between pin dimensions of splines and gears. Don't know if the book is still available though. Try contacting them or looking on ebay.
