Introduction to rotary motion


Introduction to flat pulleys:

Rotary motion is the most common type of motion for a shaft or an axle. One way in which an engineer uses rotary motion is by transmitting it from one shaft to another when the shafts are parallel. This can be done by using pulleys and belts. A pulley is a wheel which may or may not have a grooved rim.
The figure below shows a stacked vee pulleys and vee belts often used in car engines.






The main function of pulleys and belt systems are to transmit motion and torque from an engine to a machine. Various types of pulleys and belts are used on different machines. Machines used in the home, such as sewing machines, washing machines, spin dryers and vacuum cleaners. The picture below shows a flat belt and flat pulley used to transmit motion from an old heat engine.
