PULLEYS AND ROUND BELT
Pulleys can be used to transmit torque the same way that gears and chain can, but they are also used to move objects.
Pulleys are connected by belts in a manner that is very similar to the way that chain connects sprockets (Figure 63).
Figure 63: Pulleys with Round Belting
Belts are cut to length and then the belt ends are connected using a small metal part called a barb. The barb is forced into
the two ends of the belt to form a loop. Belt systems are more prone to slipping than sprockets and chain or gears;
therefore, belts should be tight in order to effectively transmit torque and prevent slip. It is important to keep this
characteristic in mind when building systems that require high torque.
