The formula to calculate the Maximum Length of Path of Approach is:
\[ P1 = r \cdot \sin(\Phi_{gear}) \]
Where:
Path of approach is the portion of the path of contact from the beginning of contact to the pitch point.
Let's assume the following values:
Using the formula:
\[ P1 = 0.0102 \cdot \sin(0.55850536063808) \]
Evaluating:
\[ P1 = 0.00540517649517778 \text{ m} \]
The Maximum Length of Path of Approach is 0.00540517649517778 meters.
