Calculation
n₂ = n₁ / i
A reduction ratio i > 1 lowers speed proportionally.
n₂ = n₁/i
Gearbox output speed

Result
Select a target and calculate.
Understand the inputs
- Output speed n₂ — Speed of the driven gear.
- Input speed n₁ — Speed of the driving gear.
- Gear ratio i — Ratio n₁/n₂.
Example
1,500 rpm / 2.5 = 600 rpm.
Assumptions and limits
Ideal gearing; slip and load losses are excluded.
