Calculating gearbox output speed To calculate gearbox output speed (n2), you need two factors: 1. **Input speed (n1)**: Engine speed, which is usually listed on the license plate. 2. **Conversion ratio (i)**: The ratio of input to output revolutions. The formula for calculating output speed The formula for calculating output speed is as follows: \[ n2 = \frac{n1}{i} \] **here:** – \(n2\) = output speed of gearbox – \(n1\) = Input speed (engine speed) – \(i\) = Gearbox conversion ratio Practical example Suppose that the engine input speed (\(n1\)) is equal to 1400 RPM and the conversion ratio (\(i\)) is equal to 100. Using the formula, the output speed \(n2\) is calculated as follows: \[ n2 = \frac{1400}{100} = 14 \text{ RPM} \] This means the gearbox with this conversion ratio, the output speed is 14 will have revolutions per minute.Conclusion For any kind of industrial or engineering activity, knowing the output speed and gear ratio is vital. This information helps us to choose the right gearbox for different projects and optimize the system performance.
