Circular Pitch for Helical Gears Solution

STEP 0: Pre-Calculation Summary

Formula Used

Circular Pitch = Normal Pitch/cos(Helix Angle)
P_c = P_N/cos(ψ)
This formula uses 1 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)

Variables Used

Circular Pitch - (Measured in Meter) - A circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth.
Normal Pitch - (Measured in Meter) - Normal Pitch is the distance between similar faces of adjacent teeth, along a helix on the pitch cylinder is normal to the teeth.
Helix Angle - (Measured in Radian) - Helix Angle is the angle between any helix and an axial line on its right, circular cylinder, or cone.

STEP 1: Convert Input(s) to Base Unit

Normal Pitch: 15 Millimeter --> 0.015 Meter (Check conversion here)
Helix Angle: 25 Degree --> 0.4363323129985 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_c = P_N/cos(ψ) --> 0.015/cos(0.4363323129985)

Evaluating ... ...

P_c = 0.0165506687844367

STEP 3: Convert Result to Output's Unit

0.0165506687844367 Meter -->16.5506687844367 Millimeter (Check conversion here)

FINAL ANSWER

16.5506687844367 ≈ 16.55067 Millimeter <-- Circular Pitch
