Belts have been transmitting power and rotary motion for centuries. But today’s belts are not made of leather and are not, for the most part, turned by water wheels. They are made of highly engineered materials and can deliver hundreds of horsepower at nearly 99% efficiencies while traveling at over 15 feet per minute. There are also a wide variety of belts, including flat belts that run quietly at a fraction of the cost of gears, V belts that deliver high driving forces, and synchronized belts with teeth that mesh with the pulleys for synchronized motion and accuracy. Here are some of the belts engineers have at their disposal to efficiently and elegantly solve both power and motion challenges.
