A pulley is a wheel on an axle or shaft that is designed to support movement and redirect tension. They are simple, yet powerful devices that can make small forces move large objects. Pulleys are used to make heavy work more manageable.
What are pulleys used for?
Pulleys are commonly used in shipping and marine applications, as well as for industrial equipment and heavy machinery. Systems typically use multiple pulleys to increase mechanical advantage as it reduces the force needed to lift or pull the weight. However, the increased number of pulleys used decreases the efficiency of the system due to friction.
A specialized block and tackle system is widely used for sailing vessels and fishing ships to allow for operators to lift heavy loads with minimal force. For industry pulleys, there are a few types of belt options:
- Timing belt – Contains notched teeth to mesh with the teeth of the matching belt
- Flat belt – A smooth belt that does not contain notches
- Round belt – Used to transmit rotational motion around an axle
- V-belt – Contains an angled track to coincide with the matching belt that passes through
What are industry pulleys made of?
Industry pulleys can be made from a variety of materials including plastic, steel, and aluminum alloys. Many designs use multiple materials to combine strength and increased resistance.
