Details

I am needing help with a gear ratio  and  energy loss calculation.

I have an energy source that is turning a 12 inch sprocket at a rate of 3 mph.

Via a gearbox it is turning a power generator 1800 RPMs.

1. What type of gearbox would you recommend.
2. What would be the losses due to friction.
3. After further discussion, would you be interested in contracting to provide a detailed design?
