AGMA Announces Adoption of ISO 1328-1 Cylindrical Gears

AGMA Announces Adoption of
ISO 1328-1 Cylindrical gears — ISO system of flank tolerance classification
Part 1: Definitions and allowable values of deviations relevant to flanks of gear teeth

AGMA Technical Division is proud to announce the ADOPTION of the recently published new revision of ISO 1328-1:2013, Cylindrical gears — ISO system of flank tolerance classification — Part 1: Definitions and allowable values of deviations relevant to flanks of gear teeth.

As the US Technical Advisory Group to ISO Working Group 2, members of the AGMA Gear Accuracy Committee were instrumental in the development of the ISO document. In fact, the new ISO standard was based on the AGMA standard on the subject, ANSI/AGMA 2015-1-A01, which was developed by AGMA Gear Accuracy committee and offered to ISO as the base for the development of the new international standard. The intent was to have the document published as an ISO standard and then adopt it as an AGMA/American National Standard.

Following up on their intent, the AGMA Gear Accuracy Committee recommended and the AGMA Technical Division Executive Committee approved the adoption of the new ISO 1328-1. The adoption was later approved by the AGMA membership and the AGMA Board of directors. The adopted document has been approved, by ANSI, for publication as ANSI/AGMA ISO 1328-1-B14.

The new standard establishes a tolerance classification system relevant to manufacturing and conformity assessment of tooth flanks of individual cylindrical involute gears. It specifies definitions for gear flank tolerance terms, the structure of the flank tolerance class system, and allowable values.

The new standard is available for purchase, click on the “STANDARDS” button.

The AGMA Gear Accuracy Committee wishes to thank all participants for their valuable contributions to the development and adoption of this new standard.
