ABSTRACT:
An idler mechanism for maintaining tension on a drive belt of a belt drive system. The idler mechanism includes a pulley mounted to an idler arm for rotation about a rotational axis. The idler arm is attached to mounting apparatus having a resilient and damping element for eliminating vibration and dissipating shock loads on the belt and establishing tension in the belt. In the preferred embodiment the resilient and damping element comprises a torsional bushing having a torsional axis parallel to the pulley rotational axis and a torsional member constructed from a block of resilient elastomeric material which provides both tension and damping.
