What is gear module (m)?
The gear module is the ratio of pitch circle diameter to the number of teeth (m = d / z). Two gears can only mesh if their modules are identical.
Calculate gear module, pitch diameter, tip diameter, center distance and transmission ratio for spur and helical gear mechanisms.
