Cylindrical gears. ISO system of flank tolerance classification - Definitions and allowable values of double flank radial composite deviations1 Scope This document establishes a gear tooth classification system relevant to double flank radial composite deviations of individual cylindrical involute gears and sector gears. It specifies the appropriate definitions of gear tooth deviations, the structure of the gear tooth flank classification system, and the allowable values of the gear tooth deviations. It provides formulae to calculate tolerances for individual product gears when mated in

This applies to preparatory site work
