Which components comprise the Sheave Assembly?

• A. Front sheave, rear sheave, absorber sheave
• B. Front, middle, rear sheave
• C. Top, middle, bottom sheave
• D. Left, right, center sheave

Answer: (A)

In this context, a sheave assembly is the belt-driven part of the system that uses two main wheels to route and drive the belt plus an additional dampening wheel. The front sheave guides and engages the belt from the front, the rear sheave continues the belt path and helps maintain tension and alignment, and the absorber sheave is designed to absorb dynamic belt loads, reducing shock, vibration, and wear. Together, these three components form the complete sheave assembly, enabling smooth power transfer and longer belt life. Other configurations either omit the absorber function or describe an arrangement that doesn’t match how the wheels are placed and work in this design, so they aren’t correct.
