About Belt Drive Power Calculator

The Belt Drive Power Calculator is a useful tool for mechanical engineering students to determine the power transmitted by a belt drive system using tension and velocity.

Formula Used

P = (T₁ − T₂) × v

• P = Power transmitted (Watts)
• T₁ = Tension on the tight side (N)
• T₂ = Tension on the slack side (N)
• v = Velocity of the belt (m/s)

Applications

• ✅ Used in pulley and belt drive systems
• ✅ Transmission of power in workshops
• ✅ Agricultural machinery
• ✅ Conveyor systems

FAQs

1. What is the function of a belt drive?

A belt drive transmits power between rotating shafts using a flexible belt.

2. Why is T₁ always greater than T₂?

Because T₁ (tight side) must carry more load, while T₂ (slack side) experiences less force.

3. What happens if T₁ = T₂?

No power is transmitted, since there is no difference in tension.

4. What are the units of power?

The power transmitted is measured in Watts (W).
