Title (EN) COMPOSITE SPROCKET
(FR) PIGNON COMPOSITE
Abstract:
(EN) A composite sprocket. The sprocket comprises a polymer outer ring (20) mounted to a metallic inner hub (10). The outer ring has a profile, for example, a toothed profile. The toothed ring comprises a thermoset material such as polyurethane. The hub comprises any suitable metallic or non-metallic material sufficient for transmitting a torque from the ring to a shaft. A retaining ring (13) or adhesives or both are used to lock the ring in place on the hub. Cooperating transverse lugs (17) on the ring and grooves (15) in the hub prevent the ring from rotating when subjected to a torque. A retaining member (13) or members are used to prevent lateral movement of the ring.
(FR) Pignon composite. Le pignon comprend un anneau extérieur en polymère (20) monté sur un moyeu intérieur métallique (10). L'anneau extérieur présente un profil, par exemple, un profil denté. L'anneau denté comprend un matériau thermodurci tel qu'un polyuréthanne. Le moyeu comprend n'importe quel matériau métallique ou non métallique approprié suffisant pour transmettre un couple de l'anneau à un axe. Une bague de retenue (13) ou des adhésifs ou les deux sont utilisés pour bloquer l'anneau en place sur le moyeu. Des barrettes transversales coopérant (17) se trouvant sur l'anneau ainsi que des rainures (15) dans le moyeu empêchent que l'anneau ne tourne lorsqu'il est soumis à un couple. Un élément de retenue (13) ou des éléments de retenue sont utilisés pour empêcher le mouvement latéral de l'anneau.
