Flexible Couplings - Nomenclature for Flexible Couplings
ANSI/AGMA 9009-D02 (reaffirmed July 2014)

SCOPE
Applicability
This standard provides nomenclature common to flexible couplings and their application as used in mechanical power transmission drives.
Exceptions
The following coupling types are not included in this standard:

  • flexible shaft;
  • quill shaft;
  • universal joint;
  • devices which exhibit slip such as clutches, fluid couplings, magnetic couplings and torque converters.

FOREWORD
[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of ANSI/AGMA Standard 9009--D02, Flexible Couplings -- Nomenclature for Flexible Couplings.]

This Standard was prepared to reduce the language barriers that arise between designers, manufacturers, and users when attempting to designate or describe various types of flexible couplings and their elements.

The first draft copy of AGMA 510.01 was prepared by the Flexible Coupling Nomenclature Committee in October, 1963. It was accepted as an AGMA Standard on July 9, 1965. AGMA 510.01 was editorially changed and approved as AGMA 510.02 in August 1969.

AGMA 510.03 was approved in October, 1983. The revised standard contained an improved clarity in definitions, simplification of nomenclature, addition of coupling physical property terms and units including SI Units, and introduction of an axial travel term for couplings.

ANSI/AGMA 9009--D02 is a revision of AGMA 510.03, and was approved by the AGMA membership in May 2001. It was approved as an American National Standard on June 27, 2002. This revision includes additional nomenclature from standards developed since the previous revision.

Suggestions for improvement of this standard will be welcome. They should be sent to the American Gear Manufacturers Association, 1500 King Street, Suite 201, Alexandria, Virginia 22314.
