I know I have another thread going on but this is slightly different topic, so I wanted to create a new thread.
number of teeth 27
spline pitch 32/64
pressure angle 30
base diameter 0.7307089
Inspection results:
no modification
min minor dia: 0.81307 inch
max minor dia: 0.81772
min major dia: 0.90230
max major dia: 0.90651
min size between balls: 0.74993
The root definitely has two fillets when zoomed in at 50X, but I cannot tell if its major diam fit or flat root side fit since both bottoms can be flat, I don't have the mating spline shaft data for this internal spline.
Since inspected major dia exceeds ANSI limit for max major diameter for the flat root side fit, can I say its major diam fit? ANSI B92.1 does not have the table for 32/64 major dia fit data.
EDIT: The max minor diameter exceeds all of the popular standards such as ANSI, SAE, J500 and AIA/NAS 580 ...I guess this is not a standard spline after all...
