Hello,
My company produces rigid shaft couplings normally of a 1.25" taper on diameter per foot. Mean diameter is between 2" and 6". It is self locking. We generally judge the form to be enough to generate 75-90% contact with the mating part based on a (very thin!) bluing contact check.
We also have some taper gauges. They were produced by a taper gauge grinding company and spec'd & calibrated against a toleranced taper angle. I don't think we were ever quoted tolerance options for these gauges - they are the gauge suppliers default tolerance. In working with them, my impression is the gauge taper angle tolerances are plenty tight.
Are there any practices or standards that would help me correlate between contact percentage and measured taper angle and form?
