Diametral Pitch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diametral Pitch = Number of Teeth on Wheel/Pitch Circle Diameter
P_d = T/d
This formula uses 3 Variables

Variables Used

Diametral Pitch - (Measured in 1 per Meter) - Diametral Pitch is the number of teeth per unit length of the pitch diameter.
Number of Teeth on Wheel - Number of teeth on wheel is the count of teeths on the wheel.
Pitch Circle Diameter - (Measured in Meter) - Pitch Circle Diameter is the diameter of the pitch circle.

STEP 1: Convert Input(s) to Base Unit

Number of Teeth on Wheel: 38000 --> No Conversion Required
Pitch Circle Diameter: 196349 Millimeter --> 196.349 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_d = T/d --> 38000/196.349

Evaluating ... ...

P_d = 193.532943890725

STEP 3: Convert Result to Output's Unit

193.532943890725 1 per Meter -->0.193532943890725 1 per Millimeter (Check conversion here)

FINAL ANSWER

0.193532943890725 ≈ 0.193533 1 per Millimeter <-- Diametral Pitch

Diametral Pitch = Number of Teeth on Wheel/Pitch Circle Diameter
P_d = T/d

What is diametral pitch of a gear?

The number of teeth of a gear per inch of its pitch diameter. A toothed gear must have an integral number of teeth. The circular pitch, therefore, equals the pitch circumference divided by the number of teeth. The diametral pitch is, by definition, the number of teeth divided by the pitch diameter.

How to Calculate Diametral Pitch?

Diametral Pitch calculator uses Diametral Pitch = Number of Teeth on Wheel/Pitch Circle Diameter to calculate the Diametral Pitch, Diametral Pitch is number of teeth of a gear per inch of its pitch diameter. Diametral Pitch is denoted by P_d symbol.

How to calculate Diametral Pitch using this online calculator? To use this online calculator for Diametral Pitch, enter Number of Teeth on Wheel (T) & Pitch Circle Diameter (d) and hit the calculate button. Here is how the Diametral Pitch calculation can be explained with given input values -> 0.000153 = 38000/196.349.
