What influences efficiency of V-Belt?

V-belt efficiency depends on the load being transmitted, sheave sizes, the number and size of belts, and their temperature. But most of all, efficiency is affected by installation and maintenance factors, such as tension, misalignment, and worn sheaves.
A well-designed, properly aligned and tensioned V-belt drive is most efficient — about 97% — when first installed. With time and use, the belts stretch, lose tension, and begin to slip in their sheaves. The result: efficiency drops to about 94%, provided that the sheaves are in good condition and slippage is normal. To minimize this drop in efficiency over time, keep belts properly tensioned and aligned.
