Rotary Transmission

These include friction wheels, belt and pulley systems, gears, chains and sprocket systems and worm gears.

Friction Wheels

They are a set of two wheels located one next to the other. Motion is transmitted between the wheels by the friction between them.

Belt and pulley system

This system is made up of two pulley wheels joined by a belt that slots into the grooved rim of the wheels.

Gears

It is a mechanism consisting of two wheels with teeth.

Chain and sprocket systems

This system consists of two sprockets separated by a distance and connected by a chain that meshes with the teeth of the two wheels.

Worm gear

This rotary trasmission mechanism consists of a worm that is fitted to de driver shaft and toothed wheel that is fitted to the driven shaft.
