METHOD FOR MANUFACTURING CLUTCH PULLEY

摘要

A method for manufacturing a clutch pulley for selectively producing friction with a disc to interrupt a power in an electromagnetic clutch is disclosed. The method includes a first step of performing hot rolling and cold rolling on a base metal of the clutch pulley to form a hub 110, a pulley 120 and a friction wall 130, a second step of performing rough boring and finish boring on an intermediate material formed in the first step to adjust a set specification of the clutch pulley 100, and a third step of forming banana slots 140 on the friction wall 130 machined in the second step by using a non-contact cutting machine. A b-pole clutch is made by minimizing a width of a banana slot formed on the clutch pulley, thereby improving its initial performance.
