US20030153419: Tensioning idler
13 Claims, 5 Drawings
The invention comprises a tensioning idler. An outer belt bearing ring is resiliently engaged to an inner ring. The belt bearing ring and inner ring each rotate about an axis of rotation. The belt bearing ring is connected to the inner ring with the resilient material whereby the belt bearing ring rotates about an axis of rotation that is eccentrically moveable in a plane with respect to an inner ring axis of rotation. The resilient material imparts a belt tension as the belt bearing ring rotates. The resilient material may comprise springs, compressible fluids, incompressible fluids, or elastomers or a combination of the foregoing. The tensioner is mounted on an engine, bracket, or other device.
