Belt disks structure and a damper - belt pulley

摘要

A belt disks structure and a damper - belt pulley, which prevent corrosion. The belt disks structure may comprise a hub part (10), which, on a by means of a power of a motor is mounted rotating crankshaft and, together with the crankshaft rotates, and a pulley member having (20), which may be connected to the hub part (10) is coupled, in order to rotate together with the hub part, and with a power transmission element is connected. The hub part (10) may comprise a belt disks contact surface (12), which is facing the pulley member having, and the belt disks coupling sections (15) which, on which the belt disks contact surface (12) are formed, in order to secure coupling elements (30). The pulley member having (20) may comprise a hubs contact surface (22), which of the belt disks contact surface (12) of the hub part (10), hubs coupling sections (25), which, with the belt disks coupling sections (15) by attachment of the coupling elements (30) are coupled, and the coupling holes (27) which, in the hubs coupling sections (25) are recessed out of the coupling elements (30) to use therein. Washers (17), which are made from an insulator, on the coupling elements (30) between the belt disks coupling sections (15) and the hubs coupling sections (25) be attached.
