请注意，本标准的翻译版本中可能不包括任何附录或勘误表。本标准规定了石油、石化和天然气工业中特殊用途的两台机器转轴之间动力传输用联轴器的要求。此类应用通常在大型和/或高速机器中，在可能需要长时间连续运行的服务中，通常是不共享的，并且对装置的持续运行至关重要。 根据协议，它可以用于其他应用或服务。所涵盖的联轴器旨在适应轴的平行（或横向）偏移、角度偏差和轴向位移，而不会对耦合机器施加不可接受的机械载荷。适用于齿轮、金属挠性元件、套筒轴和扭转弹性联轴器。附件A中详细说明了扭转阻尼和弹性联轴器；齿轮式联轴器详见附录B； 附录C中详细说明了套筒轴式联轴器。本标准还包括专用联轴器的设计、结构材料、制造质量、检验和测试。

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.
