Pitch Circle Calculator

Formula

The formula to calculate the pitch circle diameter (PCD) is:

\[ PCD = \frac{N}{DP} \]

Where:

Pitch Circle: An imaginary circle that passes through the contact points of the teeth of a gear. It is crucial for determining the size and spacing of the teeth and ensuring that gears mesh correctly.

Let's say the number of teeth (N) is 50 and the diametral pitch (DP) is 5. Using the formula:

\[ PCD = \frac{50}{5} \]

We get:

\[ PCD = 10 \]

So, the pitch circle diameter is 10 units.
