Details

Please note that any addenda or errata may not be included in translated editions of this standard.This standard specifies the requirements for couplings for the transmission of power between the rotating shafts of two machines in special-purpose applications in the petroleum, petrochemical, and natural gas industries. Such applications are typically in large and/or high-speed machines, in services that can be required to operate continuously for extended periods, are often unspared, and are critical to the continued operation of the installation. By agreement, it can be used for other applications or services. Couplings covered are designed to accommodate parallel (or lateral) offset, angular misalignment, and axial displacement of the shafts without imposing unacceptable mechanical loading on the coupled machines. It is applicable to gear, metallic flexible element, quill shaft, and torsionally resilient type couplings. Torsional damping and resilient type couplings are detailed in Annex A, gear-type couplings are detailed in Annex B, and quill shaft style couplings are detailed in Annex C. This standard also covers the design, materials of construction, manufacturing quality, inspection, and testing of special-purpose couplings.
