This standard presents criteria and guidelines for the establishment of the basis for ratings of standard flexible couplings. Due to the diversity of coupling types, details of design such as formulas and analysis used to derive the stresses, etc. are often considered proprietary and are not considered in this standard. This standard is of importance to coupling manufacturers, users and equipment designers for the proper selection, comparison and application of flexible couplings.

The intent of ANSI/AGMA 9006-A16 is to provide insight into variables that are considered by coupling designers when rating flexible couplings. This standard was developed after intensive study of existing literature, design practices, and manufacturing procedures for the rating of flexible couplings The first draft of ANSI/AGMA 9006-A16 was created in June 2005. It was approved by the AGMA membership in January 2016. It was approved as an American National Standard on April 18, 2016.
This standard presents criteria and guidelines for the basis of flexible coupling ratings. It is not a comprehensive rating method that can be applied to a specific product or manufacturer. Due to the diversity of coupling types, this standard presents generally accepted practices rather than rigorous engineering analyses. This standard is of importance to coupling manufacturers, users and equipment designers for the proper selection and application of flexible couplings.
This document is applicable to standard couplings as defined by ANSI/AGMA 9009.
Details of design, such as formulas and analyses used to derive the specific coupling stresses, are often considered proprietary and are not considered in this standard. It does not address special couplings that are engineered and manufactured specifically to meet the operating conditions of the equipment train in which they will be installed. Additionally, flexible shafts, quill shafts, universal joints, magnetic couplings, or devices which exhibit slip such as clutches, fluid couplings, or torque converters are also excluded.
The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on the American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed.
