I would like to know whether a gearbox (reducer) designed for an electric motor is suitable for the same powered 4-stroke engine.
The most common, and therefore inexpensive, gearboxes are on drills, either cordless or wired.
A small 4 stroke engine gives a maximum power of 750 watts. Would a gearbox off a 750 watt drill be suitable? or does the 4 stroke engine only powering 1/4 of the time mean that a gearbox off a 3000 watt electrical tool is needed?
I also assume that the flywheel mass will have some effect on this, could anyone explain what effect the flywheel mass would have?
Literature on cordless drills don't generally show a wattage, for the larger ones a torque of 30 nm is shown. The small 1 hp (750 watt) 4-strokes have a maximum torque of 1 nm. As I am seeking a reduction of 27:1, which would give an output torque of 26 nm, I was wondering whether these gearboxes would be OK
Many Thanks
