The formula to calculate the Helix Angle is:
\[ \psi = \tan^{-1}\left(\frac{P_{\text{screw}}}{\pi \cdot d}\right) \]
Helix Angle is the angle between any helix and an axial line on its right, circular cylinder, or cone.
Let's assume the following values:
Using the formula:
\[ \psi = \tan^{-1}\left(\frac{5}{\pi \cdot 0.06}\right) \approx 1.53311505935313 \text{ radians} \]
| Pitch (Pscrew) | Helix Angle (ψ) |
|---|---|
| 4 m | 1.523707272649169 radians |
| 4.5 m | 1.528932897774537 radians |
| 5 m | 1.533115059353132 radians |
| 5.5 m | 1.536537815682524 radians |
| 6 m | 1.539390729568477 radians |
