Abstract
A belt drive cantilever tensioner. The tensioner is particularly suited to belt drive systems having a high belt tension. The tensioner comprises a pulley journaled to a cantilever arm. The cantilever arm is pivotably attached to a mounting surface by a fastener at a pivot. The cantilever arm further comprises a hole disposed radially from the pivot for containing an embedded resilient member. A second fastener extends through the resilient member fixing it in a position relative to the first fastener. A load applied to the pulley causes the arm to pivot thereby causing a lever action to exert a force upon the resilient member. The resilient member has a limit of movement as well as an asymmetric force characteristic which increases in proportion to an arm rotation.
