Pitch Circle Diameter of Gear given Dedendum Circle Diameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Pitch Circle of Helical Gear = Dedendum Circle Diameter of Helical Gear+2*Dedendum of Helical Gear
d = d_f+2*d_h
This formula uses 3 Variables

Variables Used

Diameter of Pitch Circle of Helical Gear - (Measured in Meter) - Diameter of Pitch Circle of Helical Gear is the diameter of the pitch circle of a gear that touches the meshing gear's pitch circle.
Dedendum Circle Diameter of Helical Gear - (Measured in Meter) - The Dedendum Circle Diameter of Helical Gear is the diameter of a circle touching the root of the gear teeth.
Dedendum of Helical Gear - (Measured in Meter) - Dedendum of Helical Gear is defined as the radial distance from the pitch circle of a toothed wheel or a gear to the bottom of the tooth space or groove.

STEP 1: Convert Input(s) to Base Unit

Dedendum Circle Diameter of Helical Gear: 126 Millimeter --> 0.126 Meter (Check conversion here)
Dedendum of Helical Gear: 5 Millimeter --> 0.005 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = d_f+2*d_h --> 0.126+2*0.005

Evaluating ... ...

d = 0.136
