The formula to calculate the Length of Arc of Contact is:
\[ L = \frac{P}{\cos(\Phi_{gear})} \]
Where:
Length of arc of contact is the ratio of length of path of contact and the cosine of the pressure angle.
Let's assume the following values:
Using the formula:
\[ L = \frac{0.018}{\cos(0.55850536063808)} \]
Evaluating:
\[ L = 0.0212252112605163 \text{ m} \]
The Length of Arc of Contact is 0.0212252112605163 m.
| Path of Contact (m) | Pressure Angle of Gear (rad) | Length of Arc of Contact (m) |
|---|---|---|
| 0.017 | 0.55850536063808 | 0.020046032857 |
| 0.018 | 0.55850536063808 | 0.021225211261 |
