EN ISO 14691:2008

Petroleum, petrochemical and natural gas industries - Flexible couplings for mechanical power transmission - General-purpose applications (ISO 14691:2008)

ISO 14691:2008 specifies the requirements for couplings for the transmission of power between the rotating shafts of two 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 (stiff-shaft machines). ISO 14691:2008 can, by agreement, be used for applications outside these limits.
ISO 14691:2008 is applicable to couplings designed to accommodate parallel (or lateral) offset, angular misalignment and axial displacement of the shafts without imposing excessive mechanical loading on the coupled machines. Couplings covered by ISO 14691:2008 include gear (and other mechanical contact types), metallic flexible-element and various elastomeric types. Such couplings can be of all metal construction or can include components of non-metallic materials, such as composites.
ISO 14691:2008 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).
ISO 14691:2008 does not apply to special types of couplings, such as clutch, hydraulic, eddy-current, rigid and radial-spline types.
ISO 14691:2008 does not define criteria for the selection of coupling types for specific applications.

Industries du pétrole, de la pétrochimie et du gaz naturel - Accouplements flexibles pour transmission de puissance mécanique - Applications d'usage général (ISO 14691:2008)

L'ISO 14691:2008 spécifie les exigences applicables aux accouplements permettant la transmission de puissance entre les arbres rotatifs de deux machines pour des applications d'usage général dans les industries pétrolière, pétrochimique et du gaz naturel. Ces applications exigent généralement que les accouplements transmettent la puissance à des vitesses ne dépassant pas 4 000 r/min, entre des machines dans lesquelles la première vitesse latérale critique est supérieure à la plage de vitesses de marche (machines à arbre rigide). Ils peuvent, sous réserve d'un accord, être utilisés pour des applications en dehors de ces limites.
L'ISO 14691:2008 est applicable aux accouplements conçus pour compenser un déport parallèle (ou latéral), un désalignement angulaire et un déplacement axial des arbres sans imposer aux machines couplées une charge mécanique excessive. Les accouplements couverts par l'ISO 14691:2008 comprennent les accouplements à denture (et autres types de contact mécanique), les accouplements à éléments flexibles métalliques et divers accouplements en élastomère. Ces accouplements peuvent avoir une construction tout métal ou peuvent contenir des composants en matériaux non métalliques, tels que des composites.
L'ISO 14691:2008 couvre la conception, les matériaux de construction, le contrôle et les essais des accouplements ainsi que les méthodes de fixation de l'accouplement sur les arbres (y compris les dispositifs à douille conique et autres dispositifs spéciaux).
L'ISO 14691:2008 n'est pas applicable aux types spéciaux d'accouplements, tels que les accouplements à embrayage, hydrauliques, à courant de Foucault, rigides et à cannelures radiales.
L'ISO 14691:2008 ne définit pas de critères de sélection des types d'accouplements pour des applications spécifiques.
