Cast Iron V-Belt Pulley Machining Process | Amazing Work on Vertical Lathe Machine
A Pulley is a mechanism composed of a wheel on an axle or shaft that may have a groove between two flanges around its circumference. A rope, cable, belt, or chain usually runs over the wheel and inside the groove, if present Pulleys are used to change the direction of an applied force, transmit rotational motion or realize a mechanical advantage in either a linear or rotational system of motion.
A pulley is a mechanical device that can be used to lift heavily objects more easily. Pulleys consist of a wheel that rotates on an axle—which is a rod through the center of the wheel—and a rope, cable, or chain. There are three main types of pulleys: fixed, movable, and compound.
1- A fixed pulley’s wheel and axle stay in one place. A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.
2- A movable pulley is a pulley that is free to move up and down, and is attached to a ceiling or other object by two lengths of the same rope. Examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the gym.
3- The third type of pulley is the compound pulley, which consists of combinations of fixed and movable pulleys.
