Actual Number of Teeth on Gear given Virtual Number of Teeth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Teeth on Helical Gear = (cos(Helix Angle of Helical Gear))^(3)*Virtual Number of Teeth on Helical Gear
z = (cos(ψ))^(3)*z'
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

Number of Teeth on Helical Gear - Number of Teeth on Helical Gear is defined as the number of teeth (which mesh with another compatible toothed part to transmit or convert torque and speed) on a specimen or part under consideration.
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.
Virtual Number of Teeth on Helical Gear - The Virtual Number of Teeth on Helical Gear is defined as the number of teeth that are present on the virtual helical gear.

STEP 1: Convert Input(s) to Base Unit

Helix Angle of Helical Gear: 25 Degree --> 0.4363323129985 Radian (Check conversion here)
Virtual Number of Teeth on Helical Gear: 54 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

z = (cos(ψ))^(3)*z' --> (cos(0.4363323129985))^(3)*54

Evaluating ... ...

z = 40.199522483873

STEP 3: Convert Result to Output's Unit

40.199522483873 --> No Conversion Required

FINAL ANSWER

40.199522483873 ≈ 40.19952 <-- Number of Teeth on Helical Gear
