A big V belt, also known as a broad V belt, is a type of belt used in power transmission systems. Unlike standard V belts, big V belts have a wider profile, allowing them to transmit more power. They are designed to fit into V-shaped grooves on pulleys, enabling them to grip effectively and drive machinery with increased efficiency. The design of a big V belt usually incorporates strong, durable materials like rubber or synthetic composites, which provide flexibility and strength.
