Title
(DE) SCHRUMPFRING
(EN) MULTI-CRIMP RING
(FR) BAGUE DE SERRAGE
Abstract
(DE)
Ein Schrumpfring, dessen beide Umfangskanten (10) gebördelt sind, gestattet wegen seiner größeren Eigensteifigkeit die Anwendung dünnerer Bandstärken ohne die Gefahr eines Einknickens. Die Bördelung besteht in einer Durchmessererweiterung der Ringkanten, wobei die Ringkantenbereiche (14) verrundet auswärts gebogen sind und die Kantenflächen (11) unter einem Winkel von vorzugsweise 45° zur Ringachse verlaufen.
(EN)
The invention relates to a multi-crimp ring, the two circumferential edges (10) of which are flanged, which makes it possible to use thinner band thicknesses without the risk of buckling due to its greater intrinsic strength. The flanging consists in a widening of the diameter of the ring edges, wherein the regions (14) of the ring edges are bent outwards in a rounded manner and the edge surfaces (11) run at an angle of preferably 45° to the ring axis.
(FR)
L’invention concerne une bague de serrage, dont les deux arêtes périphériques (10) sont rabattues, qui permet, de par sa rigidité intrinsèque renforcée, l’utilisation d’épaisseurs de bande plus minces sans risque de flambage. Le rabattement des bords consiste en une augmentation du diamètre des arêtes annulaires, les zones de arêtes annulaires (14) étant cintrées vers l'extérieur de manière arrondie et les surfaces d'arêtes (11) s'étendant selon un angle de préférence de 45° par rapport à l'axe de la bague.
