How does a wedge V-belt differ from a classic V-belt?

The wedge V-belt is designed with a wider and flatter shape compared to a classic V-belt, which allows for greater surface contact with the pulley. This increased contact area enhances the belt's traction and load-carrying capacity, leading to improved power transmission efficiency and reduced slippage. The shape of the wedge V-belt allows it to fit more snugly into the pulley groove, which is particularly beneficial in high-torque applications where reliable power transfer is crucial. This design characteristic enables wedge V-belts to handle heavier loads than classic V-belts, making them a preferred choice in applications requiring high performance.
