Center to Center Distance between Spur Gears Solution

Follow our step by step solution on how to calculate Center to Center Distance between Spur Gears?

FIRST Step Consider the formula

a = m \cdot (\frac{z p + z}{2})

Next Step Substitute values of Variables

∴

a = 4.1mm \cdot (\frac{12 + 30}{2})

Next Step Convert Units

∴

a = 0.0041m \cdot (\frac{12 + 30}{2})

Next Step Prepare to Evaluate

∴

a = 0.0041 \cdot (\frac{12 + 30}{2})

Next Step Evaluate

∴

a = 0.0861m

LAST Step Convert to Output's Unit

∴

a = 86.1mm
