How does belt tension affect performance?

How does belt tension affect performance?

Too Low: Causes tooth jumping, inaccurate positioning, excessive wear on tooth tips, and abnormal noise (flapping).
Correct Tension: Ensures smooth power transmission, precise synchronization, optimal belt life, and minimal noise.
Too High: Increases bearing loads (potentially causing premature bearing failure), reduces belt life due to high cord stress, increases energy consumption, and can lead to excessive noise and heat generation.
