Zusammenfassung
Equations for double-flank contact measurements as used in involute gear metrology are presented with their detailed mathematical derivations. All formulas can be applied to either internal or external and either spur or helical gears, even when considering profile shift. Moreover, a proposal for measurements using different stylus radii ensures comparability for the evaluation of the dimension over (or between) balls MdK. The influence of the stylus sphere radius on MdK is illustrated via a numerical example. All equations are derived for error-free gears.
