Abstract

This standard establishes the calculation procedures for determining specification limits for external and
internal cylindrical involute gearing with constant gear ratio when the desired tooth thickness is known.
This standard also shows the relationships between backlash and the tooth thickness, centre distance,
and tooth deviations in a pinion and gear mesh.
