⚙️ Gear Ratio Calculator
Calculate gear ratios, speed ratios, and mechanical advantage for gear systems
📐 Gear Ratio Formulas
GR = N₁/N₂ = D₁/D₂ = ω₂/ω₁
Speed Ratio = ω₁/ω₂ = N₂/N₁
Torque Ratio = T₂/T₁ = N₁/N₂
Power = T × ω
GR = gear ratio, N = number of teeth, D = diameter, ω = angular velocity, T = torque
💡 Tips
- Gear ratio > 1 means speed reduction and torque increase
- Gear ratio < 1 means speed increase and torque reduction
- Power input equals power output (minus losses)
- Consider gear efficiency in calculations
- Worm gears provide high reduction ratios
- Planetary gears offer multiple ratio options
