20080207368 | Plate-link chain - A toothed plate-link chain composed of a plurality of interconnected plates that form chain links. The chain links are hingedly interconnected to adjacent links by transversely-extending hinge pins. A least some of the links include outer guide plates having convexly-curved ends that are so configured that the ends of adjacent guide plates contact each other when the chain is at a predetermined limiting angle of deflection during a swing-back mode, which deflection direction is in a direction opposite to the direction of deflection of the chain as it passes around a toothed wheel. The limitation of chain deflection during a swing-back mode serves to limit the frequency and amplitude of strand oscillations and thereby reduces the noise that would otherwise result from strand oscillations. | 08-28-2008 |
