MECHANISMS
Rotary Motion Mechanisms
Friction Drives
The ratio between the rotation velocity of the wheels or pulleys depends on the relative size of the wheels.
N1·D1=N2·D2=> D1/D2=N2/N1
Pulleys with belt

Gear Mechanisms and Cogwheels
The ratio between the rotation velocities of the wheels depends on the number of teeth on each wheel.
N1·Z1=N2·Z2=>Z1/Z2=N2/N1
Worm Gear
This is a screw that moves a helical cogwheel that is set perpendicular to the screw
Nwheel=Nscrew·Zgrooves/Zwheel
Gear Mechanisms with a chain
The relation between the rotation velocities of the wheels dependes on the number of teeth on each gear
N1·Z1=N2·Z2=>Z1/Z2=N2/N1
Gear Train
The gear ratio between the drive wheel (1) and the driven wheel (4) depends on the number of geared teeth in the system
N4/N1=Z1·Z3/Z2·Z4
Pulley trains with belts
The gear rato between the drive pulley (1) and the driven pulley (4) depends
on the relative size of the pulleys in the system. It's expressed as a function of
their diameters
