Wedge Wrapped V Belt is a type of power transmission belt that is commonly used in industrial applications. It has a trapezoidal cross-section, with a wider top surface and narrower bottom surface. The belt is wrapped around a pulley and the tight side of the belt is in contact with the pulley, providing the necessary friction to transfer power. The wedge design of the belt allows for a greater contact area between the belt and pulley, resulting in higher power transmission capacity and more efficient operation.
