A gear ratio is the relationship between the number of teeth
in two interacting gears. Interacting gears might refer to two
gears that are meshed or otherwise connected, two gears
connected by a roller chain, or even two pulleys connected
by a drive belt. The gear ratio of two sprockets connected
with a chain is exactly the same as the gear ratio of those
sprockets directly meshed.
A gear ratio is defined as follows: number of follower
gear’s teeth : number of driver gear’s teeth.
For instance, if we drive a 24-tooth gear with an
8-tooth gear, the gear ratio, also known as the torque ratio,
is 24:8. Know, however, that we should reduce both numbers
in a gear ratio until one of them is 1. To do this, we need to
find a divisor, usually equal to the smaller number. As you can see here, if we divide both numbers in a 24:8 gear setup
by 8, we will get a 3:1 ratio, which is much more convenient
and immediately shows us that three revolutions of a driver
gear result in a single revolution of a follower gear
