What are the three basic components of a belt drive system?

The three basic components of a belt drive system are the V-belt, drive sheave, and driven sheave.

In a belt drive system, the V-belt serves as the component that transmits power from one part of the system to another. It operates on the principle of friction, where it rides in the grooves of the sheaves. The drive sheave is the sheave connected to the driving component, often a motor, and is responsible for imparting motion to the belt. The driven sheave, on the other hand, is linked to the load that needs to be moved or powered by the drive system.

Together, these components work in unison; as the drive sheave rotates, it causes the V-belt to move, which subsequently turns the driven sheave, thus providing the necessary power transfer. This configuration allows for efficient and effective torque transmission in various machinery applications, making it a foundational aspect of mechanical systems that require motion.

In understanding the options, while other choices mention various components, they do not encapsulate the core elements of a typical belt drive system like the chosen answer does.
