Abstract:

Currently, two standard gear systems are available in the international market, namely, English (also called American) and Metric. Surprisingly, although the two standard systems are almost identical except using different units of measurement, yet they are not interchangeable! It could be said that gear standards lack standardization. . Meaningless terminology parameters have been replaced with meaningful terms for Bevel gear. It is recommended to use the single angular pitch as an appropriate equivalence rather than defining a linear pitch on multiple circles (circular pitch, base pitch, addendum pitch, or ded and um pitch).The "single angular pitch" term can be used as an appropriate equivalent term for the above traditional terms.
