Basic Construction of Belt Pulleys

Basic Construction

Flexible belt pulleys generally consist of a hub, which attaches to the shaft, and a groove or series of grooves on the outer circumference designed to engage with the belt. The hub can be made of metals such as steel, aluminum, or cast iron, depending on the application's requirements for strength, weight, and corrosion resistance. The groove design is crucial for maintaining a secure grip on the belt, preventing slippage, and optimizing power transmission efficiency.
