## Normal Module Solution

STEP 0: Pre-Calculation Summary
Formula Used
normal_module = Transverse Module*cos(Helix Angle)
mn = m*cos(α)
This formula uses 1 Functions, 2 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Transverse Module - Transverse Module is the module of the gear measured in the plane of rotation. (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)
STEP 1: Convert Input(s) to Base Unit
Transverse Module: 40 Millimeter --> 0.04 Meter (Check conversion here)
Helix Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
mn = m*cos(α) --> 0.04*cos(0.5235987755982)
Evaluating ... ...
mn = 0.0346410161513775
STEP 3: Convert Result to Output's Unit
0.0346410161513775 Meter -->34.6410161513775 Millimeter (Check conversion here)
FINAL ANSWER
34.6410161513775 Millimeter <-- Normal Module

### Normal Module Formula

normal_module = Transverse Module*cos(Helix Angle)
mn = m*cos(α)

## Define Helical Gears ?

A helical gear has a cylindrical pitch surface and teeth that follow a helix on the pitch cylinder. External helical gears have teeth that project outwards, whereas internal helical gears have teeth that project inwards.

## How to Calculate Normal Module?

Normal Module calculator uses normal_module = Transverse Module*cos(Helix Angle) to calculate the Normal Module, The Normal Module formula is defined 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. Normal Module and is denoted by mn symbol.

Here is how the Normal Module calculation can be explained with given input values -> 34.64102 = 0.04*cos(0.5235987755982).

### FAQ

What is Normal Module?
The Normal Module formula is defined 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 and is represented as mn = m*cos(α) or normal_module = Transverse Module*cos(Helix Angle). Transverse Module is the module of the gear measured in the plane of rotation and 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.
