石油、化工和天然气工业服务的专用联轴器

[中文适用范围]： 本标准规定了石油、石化和天然气工业中特殊用途应用中用于两台机器旋转轴之间动力传输的联轴器的要求。此类应用通常用于大型和/或高速机器，在需要长时间连续运行的服务中，通常不备用，对装置的持续运行至关重要。经协议，也可用于其他应用或服务。本标准涵盖的联轴器设计用于适应轴的平行（或横向）偏移、角度不对中和轴向位移，而不会对联接的机器施加不可接受的机械载荷。适用于齿轮式、金属弹性元件式、空心轴式和扭转弹性式联轴器。扭转阻尼和弹性式联轴器在附录B中详述，齿轮式联轴器在附录C中详述，空心轴式联轴器在附录D中详述。本标准涵盖特殊用途联轴器的设计、材料结构、制造质量、检查和测试。本标准未定义特定应用中选择联轴器类型的标准。本标准不适用于其他类型的联轴器，如离合器、液压、涡流、刚性、径向花键、链条和波纹管类型。 [外文原描述]： Petroleum, petrochemical and natural gas industries flexible couplings for mechanical power transmission- Special-purpose applications 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 couplin
