Abstract
The present invention provides a method of manufacturing combination gears and compound gears having challenging geometries using powder metal technology. This method allows for the production of combination gears and compound gears having any combination of straight or helical gear faces even in cases where the smaller gear intersects the flange of the larger gear creating an inside corner. The subject invention more specifically relates to a method for manufacturing a combination gear or a compound gear having a larger diameter gear face and a smaller diameter gear face, said method comprising molding a powder metal composition into a green preform having the smaller diameter gear face and a larger diameter cylindrical blank face, and subsequently machining the larger diameter cylindrical blank face into the larger diameter gear face.
