What type of belt is commonly used in power transmission applications?

In power transmission applications, the V-belt is the most commonly used type of belt due to its design, which provides effective grip and traction on pulleys. The trapezoidal shape of the V-belt allows it to fit snugly into the grooves of V-pulleys, enhancing its ability to transmit power efficiently while reducing slippage. This design also enables the belt to accommodate changes in load and speed, making it highly versatile for a variety of machinery and high-torque applications.

Moreover, V-belts are particularly favored because they are capable of handling high RPMs and provide a successful transfer of energy over long distances with minimal wear and tear. Their construction typically includes multiple layers and fibers that add to their strength and durability, further adding to their effectiveness in demanding environments.

In contrast, while flat belts, round belts, and link belts have their applications, they do not offer the same level of efficiency in power transmission as V-belts, especially in high-torque and dynamic load scenarios. This highlights why V-belts are the preferred choice in many industrial settings.
