Circular Pitch for Helical Gears Calculator

Calculate Circular Pitch





Formula

The formula to calculate the Circular Pitch for Helical Gears is:

\[ P_c = \frac{P_N}{\cos(\psi)} \]

Where:

Definition

A circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth.

Example Calculation

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.
