Erdöl- und Erdgasindustrie - Elastische Kupplungen für mechanische Kraftübertragung - Allgemeine Anwendungen (ISO 14691:1999)
1.1 Diese Internationale Norm legt die Anforderungen für Kupplungen für die Kraftübertragung zwischen den rotierenden Wellen zweier Maschinen für die allgemeine Anwendung in der Erdöl- und Erdgasindustrie fest. Derartige Anwendungen erfordern üblicherweise Kupplungen, die Kräfte bei Drehzahlen übertragen, die nicht über 4000 U/min hinausgehen, zwischen Maschinen, bei denen die biegekritische Drehzahl erster Ordnung über dem Bereich der Betriebsdrehzahl (stiff-shaft machine) liegt. Es ist zulässig, diese Norm bei Vereinbarung auch außerhalb dieser Grenzen anzuwenden.
1.2 Diese Internationale Norm ist anwendbar für Kupplungen, die konstruiert sind, um Parallelversatz (oder Längsversatz), Winkelabweichung und Axialverschiebung der Wellen auszugleichen, ohne den gekuppelten Maschinen übermäßige mechanische Belastung aufzuzwingen. Die in dieser Norm enthaltenen Kupplungen schließen Zahnradkupplungen (und andere mechanische Eingriffskupplungen), metallische Ausgleichselemente und verschiedene Elastomertypen ein. Spezielle Typen wie lösbare Kupplungen, hydrauliche Kupplungen, Wirbelstromkupplungen, starre Kupplungen, Radialkeilnutkupplungen und Kreuzgelenktypen sind nicht enthalten.
1.3 Diese Internationale Norm behandelt die Konstruktion, die Werkstoffe, die Abnahme und Prüfung der Kupplungen und die Verfahrensweisen der Befestigung der Kupplung auf den Wellen (einschließlich konischer Führungen und andere patentrechtlich geschützte Teile). Diese Internationale Norm legt keine Kriterien für die Auswahl von Kupplungstypen für besondere Anwendungen fest.
1.4 Es wird empfohlen, dass Betreiber, die neue Kupplungen an bereits vorhandene Geräte montieren, die sich von den ursprünglich montierten Teilen unterscheiden, die Hersteller der Antriebsmaschine oder der angetriebenen Maschine konsultieren.
ANMERKUNG 1 In vielen Fällen sind Kupplungen, die in dieser Internationalen Norm behandelt werden, Bestandteil von Herstellerkatalogen.

Foreword
ISO (the International Organization for Standardization) is a world-wide federation of national standards bodies (ISO
member bodies). The work of preparing 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, 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 International 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, Materials, equipment and
offshore structures for the petroleum and natural gas industries, Subcommittee SC 6, Processing equipment and
systems.
Annexes A, B and C of this International Standard are for information only.

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 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 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 variations from this International Standard and provide details.
This International Standard requires the purchaser to specify certain details and features.
A bullet (l) 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 the quotation request (enquiry) or in the order.

Petroleum and natural gas industries — Flexible couplings
for mechanical power transmission — General purpose
applications
1 Scope
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 speeds 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.
This International Standard is applicable to couplings designed to accommodate parallel (or lateral) offset,
1.2
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 such 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 other 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 manufacturers of the driving or driven equipment.
NOTE 1 In many cases, couplings covered by this International Standard are manufacturer’s 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 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 particularly 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
publications 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 applies. Members of ISO and
