Abstract
A chain tensioning device links multiple tensioning arms to a common link, causing the tensioning arms to rotate into and displace chain strands with a single applied force and motion. The two tensioning arms rotate and tension proportionally, and when the pivot pin distances are equal, the two tensioning arms rotate and tension equally. The chain tensioner is preferably used to tension two slack chains flanking an auxiliary drive shaft. The chain tensioner is biased against the chain by a hydraulic tensioning assembly in one embodiment and by a spring tensioning assembly in another embodiment.
