I am designing a gear reducer for a medium duty kind of vehicle that needs to be economically manufactured in volumes of about 1000 units per year. Powder metallurgy is not an option at this moment, the tooling costs are too high. Would prefer to keep process in North America. The accuracy grade of the gear can be fairly low (2015 grade 7) A couple of the gears are pretty thin in comparison to their diameter, lets say 7/16" thick with a diameter of around 6-1/2", one is a ring gear about 1/2" thick by 6-1/2". The module of the gears is in the range of 2.5 (DP about 10).
In order to keep the cost of the gears low I am considering the possibility of making these gears in the following way:
-blanks cut from hot rolled 1045 plate by laser
-blanks hardened to RC30-35
-blanks blanchard ground
-center hole machined to size
-blanks hobbed in stacks
Does this sound like a viable approach? Anyone have an idea on how to make these gears more economically?
