## Helix Angle When Center to Center Distance Between two Gears is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
helix_angle = acos(Normal Module*(Number of Teeth 1+Number of Teeth 2)/(2*Center to center distance of gears))
α = acos(mn*(z1+z2)/(2*a))
This formula uses 2 Functions, 4 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
acos - Inverse trigonometric cosine function, acos(Number)
Variables Used
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)
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.
Center to center distance of gears - The Center to center distance of gears value (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Normal Module: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)
Number of Teeth 1: 30 --> No Conversion Required
Number of Teeth 2: 30 --> No Conversion Required
Center to center distance of gears: 0.01 Meter --> 0.01 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
α = acos(mn*(z1+z2)/(2*a)) --> acos(1E-06*(30+30)/(2*0.01))
Evaluating ... ...
α = 1.56779632229488
STEP 3: Convert Result to Output's Unit
1.56779632229488 Radian -->89.8281124036456 Degree (Check conversion here)
89.8281124036456 Degree <-- Helix Angle
