I could use help with a design project

    I could use help with a design project :)

    Hey guys, I would love if you could help me with my design project.

    I have to design a one stage speed reducer. For simplification it will only be composed of 2 gears and 4 bearings (2 per gear): As the two videos below show:

    The assembly has to be as cheap and as small as possible.

    Using information from existing gears and bearings I have to find the best combination of size and price, so that the product of price (in $) and area is as small as possible.

    Gears: http://www.mcmaster.com/#gears/=jt9vwe
    Bearings: http://www.mcmaster.com/#standard-ball-and-roller-bearings/=jt9wcp

    The area is calculated as A=(Diameter Gear 1 + Diameter Gear 2) * (2*bearing thickness * gear thickness)


    Information that I have is engine specifications, desired gear ratio, reliabilities of bearings and gears, and other related information)

    I don't want you to work out this for me since it is my job. But if you could throw some ideas as to how to tackle this problem that would be amazing.

    If you are interested please let me know and I will give you more detailed information.

    Thanks!
