V-belt is actually a type of power transmission belt that is connected to two or more pulleys. The profile or cross-section of the V-belt has two parallel lines with a longer length on the top and a shorter length on the inside, that is, the surface that is placed on the pulley, and the two side surfaces are conical and in the shape of the English letter V. The connecting pulleys of V-Belt تسمه وی بلت are sometimes grooved and sometimes they are flat without grooves, which means that V-Belts can also be produced with grooves or plain ones.
V-belts are the oldest and most widely used type of power transmission belts تسمه انتقال نیرو, and hence they are sometimes known as classic belts. Due to having a trapezium cross-section, V-Belts have a better fit on the money surface with an increase in tensile stress. With the increase of the contact friction, it increases the possibility of transferring a higher amount of torque between the generator and the slave pulley, which is considered one of the advantages of the V-belt power transmission belt تسمه انتقال نیرو. The increase in contact friction between the pulley and the V-belt minimizes the loss of energy due to sliding, which is known as the slippage phenomenon.
