DAMPER PULLEY OF ELECTRIC CONDUCTIVITY

摘要

A conductive damper pulley is provided to improve electricity flow and to prevent spark by employing a conductive rubber to a damper pulley that is mounted on a crank shaft. A hub(21) is coupled to a crank shaft to be rotated therewith. A pulley(22) is rotated by the rotation of the hub and rotates a rubber belt connected to an external apparatus. A conductive rubber(23) is coupled between the hub and the pulley to attenuate oscillation by the hub or the pulley. The conductive rubber discharges friction electricity generated between the rubber belt and the pulley to the hub. A conductive sleeve(24) is inserted into the hub and the conductive rubber to connect them together.
