ABSTRACT:
A laminated gear and a method of forming the laminated gear are disclosed. The method comprises punching a central hole and a circular array of closely adjacent perforations in a generally planar sheet. The array defines an interior portion having the outline of the gear, and a selvedge portion disposed outboard the perforations. The central hole and the perforations are progressively stamped until they have burnished faces perpendicular to the sides of the sheet. Web portions interconnecting the interior and selvedge portions are then broken to separate the gear from the sheet. A projection and corresponding recess are then stamped on the opposite sides of the gear. A predetermined number of gears are queued and finally arranged into an assembly by frictionally nesting the projections and corresponding recesses. The central holes are thereby aligned to form a bore adapted to be press fit onto a camshaft or crankshaft. The laminated gear formed by this method is also disclosed.
