## Normal Module When Center to Center Distance Between two Gears is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
normal_module = Center to center distance of gears*(2*cos(Helix Angle))/(Number of Teeth 1+Number of Teeth 2)
mn = a*(2*cos(α))/(z1+z2)
This formula uses 1 Functions, 4 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Center to center distance of gears - The Center to center distance of gears value (Measured in Meter)
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)
Number of Teeth 1- Number of Teeth 1 is defined as the number of teeth that are present on the gear 1.
Number of Teeth 2- Number of Teeth 2 is defined as the number of teeth that are present on the gear 1.
STEP 1: Convert Input(s) to Base Unit
Center to center distance of gears: 0.01 Meter --> 0.01 Meter No Conversion Required
Helix Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Number of Teeth 1: 30 --> No Conversion Required
Number of Teeth 2: 30 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
mn = a*(2*cos(α))/(z1+z2) --> 0.01*(2*cos(0.5235987755982))/(30+30)
Evaluating ... ...
mn = 0.000288675134594813
STEP 3: Convert Result to Output's Unit
0.000288675134594813 Meter -->0.288675134594813 Millimeter (Check conversion here)
0.288675134594813 Millimeter <-- Normal Module
