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 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.
FOREWORD
In 2016, the AGMA Gear Accuracy Committee, acting as the US TAG to ISO TC 60/WG 2, proposed ANSI/AGMA 2015-2-B15 as the basis for the revision of ISO 1328-2.
ISO 1328-2:2020 was published by ISO TC 60. The new revised standard replaces the first edition, ISO 1328-2:1997.
The main changes compared to the previous edition are as follows:
The AGMA Gear Accuracy Committee voted to adopt the new ISO 1328-2:2020 in October 2020. The first draft of ANSI/AGMA ISO 1328-2-A21 was made in January 2021. It was approved by the AGMA membership in May 2021. It was approved as an American National Standard on October 22, 2021.
ABSTRACT
This document establishes a gear tooth classification system relevant to double flank radial composite deviations of individual cylindrical involute gears and sector gears. It provides formulae to calculate tolerances for individual product gears when mated in double flank contact with a master gear.
