v belt standard size chart

A V-belt is a type of belt that features a trapezoidal cross-section, resembling the shape of the letter V. This design allows the belt to fit snugly into the grooved pulleys that are typically used in machinery. By converging toward the center, V-belts increase the friction between the belt and the pulley, allowing for more torque transmission without slippage. They are engineered to effectively transfer power from one or more driving pulleys to driven pulleys in machinery, helping to drive the desired loads efficiently.

The operation of a V-belt is relatively straightforward. When the motor turns the pulley, the belt, which wraps around the pulley, spins with it. The V-shape of the belt allows it to grip the pulley tightly, preventing slippage and ensuring that the power from the motor is effectively transmitted to the driven machinery. The design of the big V-belt allows for high tensile strength, which means it can handle heavy loads and high speeds without failure.
