## Normal Circular Pitch of Helical Gear Solution

STEP 0: Pre-Calculation Summary
Formula Used
circular_pitch = Transverse Diametrical Pitch/cos(Helix Angle)
Pc = P/cos(α)
This formula uses 1 Functions, 2 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Transverse Diametrical Pitch - Transverse Diametrical Pitch is defined as the pitch that is present on 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 Diametrical Pitch: 30 Millimeter --> 0.03 Meter (Check conversion here)
Helix Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pc = P/cos(α) --> 0.03/cos(0.5235987755982)
Evaluating ... ...
Pc = 0.0346410161513775
STEP 3: Convert Result to Output's Unit
0.0346410161513775 Meter --> No Conversion Required
0.0346410161513775 Meter <-- Circular pitch
