Pitch Circle Diameter of Gear given Dedendum Circle Diameter Solution

Follow our step by step solution on how to calculate Pitch Circle Diameter of Gear given Dedendum Circle Diameter?

FIRST Step Consider the formula

d = d f + 2 \cdot d h

Next Step Substitute values of Variables

∴

d = 126mm + 2 \cdot 5mm

Next Step Convert Units

∴

d = 0.126m + 2 \cdot 0.005m

Next Step Prepare to Evaluate

∴

d = 0.126 + 2 \cdot 0.005

Next Step Evaluate

∴

d = 0.136m

LAST Step Convert to Output's Unit

∴

d = 136mm
