Speed Increase Ratio Calculator

Formula

The formula to calculate the Speed Increase Ratio is:

\[ \text{SIR} = \frac{\text{IGT}}{\text{OGT}} \]

Where:

\(\text{SIR}\) is the Speed Increase Ratio
\(\text{IGT}\) is the input gear teeth
\(\text{OGT}\) is the output gear teeth

What is Speed Increase Ratio?

The Speed Increase Ratio (SIR) is a measure of how much the speed of a system is increased by the gear mechanism. It is calculated by dividing the number of teeth on the input gear by the number of teeth on the output gear.

Example Calculation

Let's assume the following values:

Input Gear Teeth (IGT) = 50
Output Gear Teeth (OGT) = 25

Using the formula:

\[ \text{SIR} = \frac{50}{25} = 2.00 \]

The Speed Increase Ratio is 2.00.
