The formula to calculate the Contact Ratio is:
\[ CR = \frac{P}{Pc} \]
Where:
The contact ratio represents the average number of teeth meshing at the same time.
Let's assume the following values:
Using the formula:
\[ CR = \frac{P}{Pc} \]
Evaluating:
\[ CR = \frac{0.018}{0.016} \]
The Contact Ratio is 1.125.
