Minimum Number of Teeth on Pinion to Avoid Interference Solution

Follow our step by step solution on how to calculate Minimum Number of Teeth on Pinion to Avoid Interference?

FIRST Step Consider the formula

Z min = \frac{2 \cdot A w}{\sqrt{1 + \frac{Z p}{T} \cdot (\frac{Z p}{T} + 2) \cdot {(\sin (Φ gear))}^{2}} - 1}

Next Step Substitute values of Variables

∴

Z min = \frac{2 \cdot 24.5mm}{\sqrt{1 + \frac{0.09}{0.13} \cdot (\frac{0.09}{0.13} + 2) \cdot {(\sin (32°))}^{2}} - 1}

Next Step Convert Units

∴

Z min = \frac{2 \cdot 0.0245m}{\sqrt{1 + \frac{0.09}{0.13} \cdot (\frac{0.09}{0.13} + 2) \cdot {(\sin (0.5585rad))}^{2}} - 1}

Next Step Prepare to Evaluate

∴

Z min = \frac{2 \cdot 0.0245}{\sqrt{1 + \frac{0.09}{0.13} \cdot (\frac{0.09}{0.13} + 2) \cdot {(\sin (0.5585))}^{2}} - 1}

Next Step Evaluate

∴

Z min = 0.209164322903282

LAST Step Rounding Answer

∴

Z min = 0.2092
