About Gear Train Speed Ratio Calculator

The Gear Train Speed Ratio Calculator helps students and engineers calculate the output speed of a gear train based on driver and driven gear teeth and input speed.

Formula Used

N₂ = (T₁ / T₂) × N₁

• N₂ = Speed of driven gear (RPM)
• T₁ = Number of teeth on driver gear
• T₂ = Number of teeth on driven gear
• N₁ = Speed of driver gear (RPM)

Applications

• ✅ Gear trains in machines
• ✅ Power transmission systems
• ✅ Automobiles and bikes
• ✅ Industrial gearboxes

FAQs

1. What is a gear train?

A gear train is a system of gears used to transmit motion and power between shafts.

2. What happens if driven gear has more teeth than driver gear?

The output speed decreases but torque increases.

3. What is speed ratio?

It is the ratio of driver gear teeth to driven gear teeth, which determines the change in speed.

4. Where is this formula used?

It is widely used in automobile transmissions, gearboxes, and mechanical machinery.
