Cylindrical gears — ISO system of flank tolerance classification — Part 2: Definitions and allowable values of double flank radial composite deviations
Preview
Summary
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 double flank contact with a master gear. Tolerance tables are not included.
This document is applicable to gears with three or more teeth that have reference diameters of up
to 600 mm.
This document does not provide guidance on gear design nor does it recommend tolerances.
