The wedge V-belt will carry the same load with what percentage smaller cross section than a conventional V-belt?

The wedge V-belt is designed with a narrower and more efficient cross-sectional profile than a conventional V-belt. This design allows it to fit into smaller sheave grooves while still maintaining or even improving power transmission capability. The wedge shape increases contact area and enhances the grip between the belt and the pulleys, which is crucial for performance.

The significant advantage of the wedge V-belt is that it can carry the same load with a cross section that is approximately 40% smaller than that of a conventional V-belt. This efficiency translates into space savings and potentially lower material costs, making it an appealing option for various mechanical drive applications. The ability to effectively transmit power with a reduced cross-sectional area not only provides engineering efficiencies but also contributes to lighter overall system designs.

In scenarios where space is constrained or where weight matters, the wedge V-belt becomes a highly desirable choice, helping to optimize the mechanical drive system's overall performance and reliability.
