## Number of Teeth on Gear When Pitch Circle Diameter is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
number_of_teeth = Pitch Circle Diameter*cos(Helix Angle)/Normal Module
z = D*cos(α)/mn
This formula uses 1 Functions, 3 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Pitch Circle Diameter - Pitch Circle Diameter is the diameter of the pitch circle. (Measured in Millimeter)
Helix Angle - Helix Angle denotes the standard pitch circle unless otherwise specified. Application of the helix angle typically employs a magnitude ranging from 15° to 30° for helical gears, with 45° capping the safe operation limit. (Measured in Degree)
Normal Module - Normal Module is deifined as the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth. (Measured in Millimeter)
STEP 1: Convert Input(s) to Base Unit
Pitch Circle Diameter: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)
Helix Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Normal Module: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
z = D*cos(α)/mn --> 1E-06*cos(0.5235987755982)/1E-06
Evaluating ... ...
z = 0.866025403784439
STEP 3: Convert Result to Output's Unit
0.866025403784439 --> No Conversion Required
FINAL ANSWER
0.866025403784439 <-- Number of teeth
