Arduino

In which gear do you need less engine power if smoothness is required?

Answer 1

The final power / speed taken from the shaft is just regulated by the gear ratio (the first case does not fit exactly).
Also in the first case, if the load on the shaft is significant, then such an engine will not last long. will take on all the jerks and vibrations, but you can use a clutch.
Gears are preferable if the load is large.
The belt will smooth out vibrations and jerks, but with a moderate load
. Therefore, either the belt or the gears and select the gear ratio.
Smoothness also strongly depends on the engine itself, on its characteristics.
