26、 The text of ISO 10441:2007 has been approved by CEN as EN ISO 10441:2007 without any modifications. EN ISO 10441:2007 (E) 5 Introduction This International Standard was developed from the API Std 671, 3rd edition, 1998. It is intended that the 4th edition of API Std 671 will be identical to this In
27、ternational Standard. Users of this International Standard should be aware that further or differing requirements may be needed for individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting alternative equipment or enginee
28、ring solutions for the individual application. This may be particularly appropriate where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this International Standard and provide details. This International Standard require
29、s the purchaser to specify certain details and features. A bullet () at the beginning of a subclause or paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the datasheet(s), typical examples of whic
30、h are included as Annex J; otherwise it should be stated in the quotation request or in the order. EN ISO 10441:2007 (E) 6 1 Scope This International Standard specifies the requirements for couplings for the transmission of power between the rotating shafts of two machines in special-purpose applica
31、tions 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
32、 agreement, it can be used for other applications or services. Couplings covered by this International Standard 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
33、. 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 International
34、 Standard covers the design, materials of construction, manufacturing quality, inspection and testing of special-purpose couplings. This International Standard does not define criteria for the selection of coupling types for specific applications. This International Standard is not applicable to oth
35、er types of couplings, such as clutch, hydraulic, eddy-current, rigid, radial spline, chain and bellows types. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、ine of the structure joining the two flexible elements 3.2 angular misalignment single-engagement couplings minor angle between the extensions of two machine-shaft centrelines NOTE If the shaft centrelines do not intersect, a single-engagement coupling is not appropriate. 3.3 assembly balance proced

43、assembly-balanced coupling. 3.5 axial displacement change in the relative axial position of the adjacent shaft ends of two coupled machines, usually caused by thermal expansion 3.6 component balance procedure for achieving coupling balance in which the components or factory assembled sub-assemblies
44、are balanced separately before assembly of the coupling 3.7 continuous torque rating coupling manufacturers declared maximum torque that the coupling is capable of transmitting continuously for unlimited periods 3.8 crown diameter major diameter of the external teeth of a gear-type coupling 3) ASME
