A V-belt, also known as a Vee belt, is a type of power transmission belt with a trapezoidal cross-section. It's designed to transmit mechanical power efficiently between pulleys, commonly found in various machinery and industrial applications. The V-shaped profile of the belt fits into the corresponding grooves of the pulleys, providing a reliable grip and preventing slippage. V-belts are often made from rubber or synthetic materials and are used to transfer rotational motion from one pulley to another, enabling the operation of components like pumps, fans, and generators. They are known for their flexibility, ease of installation, and cost-effectiveness, making them a popular choice for a wide range of power transmission needs in industries such as manufacturing, agriculture, and automotive.
