Calculate Gearbox Efficiency





Formula

To calculate the Gearbox Efficiency (\(Egear\)):

\[ Egear = \frac{OT}{IT \times GR} \times 100 \]

What is Gearbox Efficiency?

Gearbox efficiency is a measure of how effectively a gearbox converts input torque to output torque. It is calculated by dividing the output torque by the product of the input torque and the gear ratio, then multiplying by 100 to express it as a percentage. Higher efficiency indicates less energy loss in the gearbox.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ Egear = \frac{200}{250 \times 1.5} \times 100 \approx 53.33\% \]

The Gearbox Efficiency is approximately 53.33%.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ Egear = \frac{300}{400 \times 2} \times 100 \approx 37.50\% \]

The Gearbox Efficiency is approximately 37.50%.
