scope:

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.

Applicability

This document is applicable to standard couplings as defined by ANSI/AGMA 9009.

Exclusions

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.
