Title
(EN) NON-ROTATABLE SHAFT/HUB CONNECTION
(FR) RACCORD ARBRE/MOYEU NON ROTATIF
Abstract
(EN)
A non-rotatable shaft/hub connection, providing a shaft having a tapered end and a bore, the tapered end having at least two angled faces; a hub having a tapered opening and an aperture, wherein the tapered opening is configured to receive the tapered end, the tapered opening provides at least two tapered portions. The non-rotatable shaft/hub connection provides an anti-backlash shaft/hub interface, having a shaft adapted to be rotatably driven about an axis of rotation, the shaft having a tapered end providing a tapered, double-D configuration; and a hub, having an opening configured to receive the double-D configuration of the tapered end.
(FR)
La présente invention concerne un raccord arbre/moyeu non rotatif, qui fournit un arbre qui a une extrémité tronconique et un trou, l'extrémité tronconique ayant au moins deux faces inclinées ; un moyeu qui a une ouverture tronconique et une fenêtre, l'ouverture tronconique étant configurée pour recevoir l'extrémité tronconique, l'ouverture tronconique fournissant au moins deux parties tronconiques. Le raccord arbre/moyeu non rotatif fournit une interface arbre/moyeu anti-jeu, qui a un arbre conçu pour être entraîné en rotation autour d'un axe de rotation, l'arbre ayant une extrémité tronconique qui fournit une configuration en double D tronconique ; et un moyeu, qui a une ouverture configurée pour recevoir la configuration en double-D de l'extrémité tronconique.
