A V belt provides more friction than a flat belt due to its design and shape. The V belt is named after the V-shaped cross-section it possesses. This design element allows the V belt to have increased contact area and better grip on the pulleys, leading to improved power transmission efficiency. Here are the factors and design elements that contribute to the increased friction of a V belt:

Cross-Sectional Shape: The V belt has a trapezoidal or V-shaped cross-section, whereas a flat belt has a rectangular cross-section. The V-shaped design allows the belt to wedge tightly into the pulley groove, creating a larger contact area between the belt and the pulley compared to a flat belt. This increased contact area results in higher friction and improved power transfer.

Wedging Action: The V-shaped cross-section of the belt enables a wedging action when it comes into contact with the pulley. As the V belt is tensioned, it wedges deeper into the pulley groove, increasing the contact area even further. This wedging action helps the belt maintain a strong grip on the pulley, preventing slipping and ensuring efficient power transmission.

Deeper Grooves: The pulleys used with V belts have deeper grooves compared to those used with flat belts. These grooves are designed to accommodate the V-shaped cross-section of the belt. The deeper grooves provide more surface area for the belt to make contact with the pulley, enhancing friction and preventing the belt from slipping under load.

Tensioning System: V belts are typically tensioned using an adjustable pulley system or a mechanical tensioner. Proper tensioning is crucial for maintaining the grip and friction of the belt. When the V belt is properly tensioned, it maximizes the contact area and friction between the belt and the pulleys, ensuring efficient power transmission.

Overall, the V-shaped cross-section, wedging action, deeper grooves, and proper tensioning system of V belts work together to increase friction and improve power transmission efficiency. These design elements allow the V belt to handle higher loads, transmit more power, and operate more efficiently compared to a flat belt.
