Sheaves in mechanical systems are typically fitted with which type of belts?

In mechanical systems, sheaves are commonly paired with V-belts due to their design and functionality. V-belts have a trapezoidal cross-section that fits snugly into the grooved sides of the sheave. This shape helps to create a positive drive that minimizes slippage, which is especially useful in applications requiring high torque transfer.

The geometry of V-belts allows for effective engagement with the sheave while accommodating for variations in load and speed. This is particularly important in machinery where power transmission is critical. The increased surface contact and friction generate a reliable grip between the belt and the sheave, enhancing the efficiency and performance of the system.

Other types of belts, such as flat belts or timing belts, while functional in their own right, do not offer the same advantages in terms of grip and torque transfer when used with sheaves. Therefore, using V-belts with sheaves is a common and effective practice in various mechanical applications.
