Helix Angle of Helical Gear given Normal Module Solution

STEP 0: Pre-Calculation Summary

Formula Used

Helix Angle of Helical Gear = acos(Normal Module of Helical Gear/Transverse Module of Helical Gear)
ψ = acos(m_n/m)
This formula uses 2 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)

Variables Used

Helix Angle of Helical Gear - (Measured in Radian) - Helix Angle of Helical Gear is the angle between any helical gear and an axial line on its right, circular cylinder, or cone.
Normal Module of Helical Gear - (Measured in Meter) - The Normal Module of Helical Gear is defined as the unit of size that indicates how big or small is the helical gear.
Transverse Module of Helical Gear - (Measured in Meter) - The Transverse Module of Helical Gear is the module of the helical gear measured in the plane of rotation.

STEP 1: Convert Input(s) to Base Unit

Normal Module of Helical Gear: 3 Millimeter --> 0.003 Meter (Check conversion here)
Transverse Module of Helical Gear: 3.4 Millimeter --> 0.0034 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ψ = acos(m_n/m) --> acos(0.003/0.0034)

Evaluating ... ...

ψ = 0.489957326253728

STEP 3: Convert Result to Output's Unit

0.489957326253728 Radian -->28.0724869358582 Degree (Check conversion here)

FINAL ANSWER

28.0724869358582 ≈ 28.07249 Degree <-- Helix Angle of Helical Gear
