Dedendum Circle Diameter of Large Size Gear Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dedendum Circle Diameter of Spur Gear = Module of Spur Gear*(Number of Teeth on Spur Gear-2.5)
d_f = m*(z-2.5)
This formula uses 3 Variables

Variables Used

Dedendum Circle Diameter of Spur Gear - (Measured in Meter) - Dedendum Circle Diameter of Spur Gear is the diameter of a circle touching the root of the gear teeth.
Module of Spur Gear - (Measured in Meter) - Module of Spur Gear is the unit of size that indicates how big or small is a gear.
Number of Teeth on Spur Gear - Number of Teeth on Spur Gear is defined as the number of teeth (which mesh with another compatible toothed part to transmit or convert torque and speed) on a specimen or part under consideration.

STEP 1: Convert Input(s) to Base Unit

Module of Spur Gear: 4.1 Millimeter --> 0.0041 Meter (Check conversion here)
Number of Teeth on Spur Gear: 30 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_f = m*(z-2.5) --> 0.0041*(30-2.5)

Evaluating ... ...

d_f = 0.11275

STEP 3: Convert Result to Output's Unit

0.11275 Meter -->112.75 Millimeter (Check conversion here)

FINAL ANSWER

112.75 Millimeter <-- Dedendum Circle Diameter of Spur Gear

(Calculation completed in 00.008 seconds)
