Radius of Base Circle of Pinion Calculator

Example Calculation

Let's assume the following values:

• Radius of Pitch Circle of Pinion ($r$) = 0.0102 m
• Pressure Angle of Gear ($\Phi_{\text{gear}}$) = 0.55850536063808 rad

Using the formula:

$$r_b = 0.0102 \cdot \cos(0.55850536063808)$$

Evaluating:

$$r_b = 0.00865009058079612 \text{ m}$$

The Radius of Base Circle of Pinion is 0.00865009058079612 m.
