The work of p
25、reparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental,
26、in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft Inter
27、national Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 14691 was prepared by Technical Committee ISO/TC 67, Mate

29、T+00:00 2006, Uncontrolled Copy, (c) BSI iv Introduction This International Standard is based on the accumulated knowledge and experience of manufacturers and users of power transmission couplings in the petroleum and natural gas industries, but its use is not restricted to these industries. Users o
30、f 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 engineering solutions for the indiv
31、idual 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 requires the purchaser to specify c
32、ertain details and features. A bullet (G) at the beginning of a clause, subclause or paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information or decision should be indicated on the data sheets; otherwise it should be stated in
33、 the quotation request (enquiry) or in the order. EN ISO 14691:2000 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 15:44:24 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 Petroleum and natural gas industries Flexible couplings for mechanical power transmission General purpose applications 1 Sc
34、ope 1.1 This International Standard specifies the requirements for couplings for the transmission of power between the rotating shafts of two machines for general purpose applications in the petroleum and natural gas industries. Such applications typically require couplings to transmit power at spee
35、ds not exceeding 4 000 r/min, between machines in which the first lateral critical speed is above the running speed range (stiff-shaft machines). It may, by agreement, be used for applications outside these limits. 1.2 This International Standard is applicable to couplings designed to accommodate pa
36、rallel (or lateral) offset, angular misalignment and axial displacement of the shafts without imposing excessive mechanical loading on the coupled machines. Couplings covered include gear (and other mechanical contact types), metallic flexible-element and various elastomeric types. Special types suc
37、h as clutch, hydraulic, eddy-current, rigid, radial spline and universal joint types, are not covered. 1.3 This International Standard covers design, materials of construction, inspection and testing of couplings and methods of attachment of the coupling to the shafts (including tapered sleeve and o
38、ther proprietary devices). This International Standard does not define criteria for the selection of coupling types for specific applications. 1.4 It is recommended that, when users fit new couplings to existing equipment which are different from those originally fitted, they consult the manufacture
39、rs of the driving or driven equipment. NOTE 1 In many cases, couplings covered by this International Standard are manufacturers catalogue items. NOTE 2 For the following applications, the use of ISO 10441 is recommended : large or high-speed machines that may be required to operate continuously for
40、extended periods, are often unspared and are critical to the continued operation of the installation (special purpose applications); machines in which the first lateral critical speed is less than the maximum required operating speed (flexible-shaft machines); machines where the rotor dynamics are p
41、articularly sensitive to coupling unbalance. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publicat
42、ions do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to appli
