Sorry if this is the incorrect place to post this question.
If you have something like a motor turning a shaft at 60 revolutions
per min, how would you figure out what kind of system of gears you
would need to either increase the RPM's by a factor of 2, 5 and 10.
Increasing the rpm using gears is inefficient because friction loads are
magnified by the gear ratio. Much better to use a different motor designed
for the higher rpm.
And what kind to decrease the RPM's by the same.
To reduce the rpm by a factor of two use gears with teeth in that ratio.
Examples
25:50
50:100
I'm would think you
could use a myriad variety of gears but I'm looking for the most
simple.
That is a system that would double the RPM's.
50:25 but not ideal.
A system that would half the RPM's.
50:100
A system that would increase the RPM's 5 times.
Not recommended
A system that would increase the RPM's 10 times.
Definitly not recommended.
A system that would decrease the RPM's 5 times.
20:100
