The formula to calculate the Circular Pitch for Helical Gears is:
\[ P_c = \frac{P_N}{\cos(\psi)} \]
Where:
A circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth.
Let's assume the following values:
Using the formula:
\[ P_c = \frac{0.009}{\cos(0.4363323129985)} \]
Evaluating:
\[ P_c = 0.00993040127066204 \text{ m} \]
The Circular Pitch is 0.00993040127066204 m.
