V-belts are a type of mechanical belt used to transmit power between rotating shafts. They have a trapezoidal cross-section, which allows them to fit snugly into the grooves of pulleys. This design helps to prevent slippage and ensures efficient power transfer in various machines, such as automobiles, industrial equipment, and HVAC systems. These belts are made from durable materials like rubber or polyurethane, often reinforced with fibers for added strength. V-belts come in different sizes and specifications to suit various applications, making them a versatile choice for many mechanical systems. Regular maintenance is essential to ensure their longevity and performance.
