This International Standard is not intended

28、to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering 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

29、variations from this International Standard and provide details. For the following applications, the use of ISO 10441 is recommended: large or high-speed machines that may be required to operate continuously for extended periods, are often unspared and are critical to the continued operation of the

30、installation (special-purpose applications); machines in which the first lateral critical speed is less than the maximum required operating speed (flexible-shaft machines); machines in which the rotor dynamics are particularly sensitive to coupling unbalance. This International Standard requires the

31、 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 that further information is to be provided by the purchaser. This information should be indicated on the datasheet(s), typical examples of whic

32、h are included as Annex E, otherwise it should be stated in the quotation request or in the order. The coupling vendor is not normally required to supply the coupling guard or guards. However, for completeness and for the information of the user of this International Standard, Annex D, which provide

33、s requirements for guards, has been added. DIN EN ISO 14691:2009-05B55EB1B3E14C22109E918E8EA43EDB30F09DCEB7EF8AD9NormCD - Stand 2010-04 EN ISO 14691:2008 (E) 5 1 Scope This International Standard specifies the requirements for couplings for the transmission of power between the rotating shafts of tw

34、o machines for general-purpose applications in the petroleum, petrochemical and natural gas industries. Such applications typically require couplings to transmit power at speeds not exceeding 4 000 r/min, between machines in which the first lateral critical speed is above the running speed range (st

35、iff-shaft machines). It can, by agreement, be used for applications outside these limits. NOTE 1 Recommendations are included in the Introduction as to when the use of ISO 10441 should be considered. This International Standard is applicable to couplings designed to accommodate parallel (or lateral)

36、 offset, angular misalignment and axial displacement of the shafts without imposing excessive mechanical loading on the coupled machines. Couplings covered by this International Standard include gear (and other mechanical contact types), metallic flexible-element and various elastomeric types. Such

37、couplings can be of all metal construction or can include components of non-metallic materials, such as composites. 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 sle

38、eve and other proprietary devices). This International Standard does not apply to special types of couplings, such as clutch, hydraulic, eddy-current, rigid and radial-spline types. This International Standard does not define criteria for the selection of coupling types for specific applications. NO
