Abstract
A sheet metal pulley having a generally circular base with an upstanding circumferential flange. The flange is formed to provide teeth for engaging a toothed belt. The outer tooth sections are separated by tooth bottom sections and these sections are interconnected by intermediate walls. Reinforcing ribs extend circumferentially on the inside of the outer tooth sections between the intermediate walls on either side thereof. This patent also discloses a method for cold-forging this pulley from a sheet metal cup-like member.
