Gear design

[PCR7]

Hello all ,
We have to design gear to move a weight of 0.2kg over a distance of 0.1905m so we know the torque that comes up to =0.2*9.81*0.1905=0.37361N-m ...how do I decide the diameter ...number of teeth on pinion and driven gear ...wat are all the parameters shuld I consider for designing ..any link would be great to help me ..sorry if the question was novice with very less details ..but want to learn ...so please help me ..thanks a lot in advance

Oh, you'll find the world of gears fascinating....[/sarcasm]

Either way, things to consider when designing gears:
Number of Teeth on both pinion and gear
Face with on both
Type of Gear: Spur, helical
Pressure Angle
Diametral Pitch
Tooth Thicknesses
Edge Breaks
Addendum/Dedendum factors
Root Fillets
Speeds/Pitch Line Velocities
Materials

Now, it seems as if your task might be a bit more trivial than what I described, could you explain the application a bit more?
