A regular V-belt is a type of belt with a larger cross-sectional size, mainly used to transmit larger power and torque. Its working face is a V-shaped structure composed of two inclined planes, with a larger contact area with the pulley, thus it can withstand larger loads. Meanwhile, due to its unique cross-sectional shape, it has good stability during operation, ensuring the accuracy and reliability of transmission.

V-belt transmission relies on the frictional force generated by the compression between the two sides of the V-belt and the side of the wheel groove for power transmission. Compared with flat belt transmission, V-belt transmission has higher friction and can therefore transmit greater power. The V-belt has a more compact structure than a flat belt, and it is a seamless transmission belt, so the transmission is smoother, making it the most widely used type of belt transmission.
