Belt Tension
Definition
The tensile force in a belt, consisting of tight side tension (T₁) and slack side tension (T₂). The difference transmits power: P = (T₁ - T₂) × v. Initial tension is set to prevent slip under load.
Practical Note
Proper belt tension is critical: too loose causes slip and wear, too tight causes bearing damage and belt fatigue. Follow manufacturer specifications for tension setting.
