Efficiency of Square Threaded Power Screw Solution

STEP 0: Pre-Calculation Summary

Formula Used

Efficiency of power screw = tan(Helix angle of screw)/((Coefficient of friction at screw thread+tan(Helix angle of screw))/(1-Coefficient of friction at screw thread*tan(Helix angle of screw)))
η = tan(α)/((μ+tan(α))/(1-μ*tan(α)))
This formula uses 1 Functions, 3 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Efficiency of power screw - Efficiency of power screw refers to how well it converts rotary energy into linear energy or motion.
Helix angle of screw - (Measured in Radian) - Helix angle of screw is defined as the angle subtended between this unwound circumferential line and the pitch of the helix.
Coefficient of friction at screw thread - Coefficient of friction at screw thread is the ratio defining the force that resists the motion of the nut in relation to the threads in contact with it.

STEP 1: Convert Input(s) to Base Unit

Helix angle of screw: 4.5 Degree --> 0.0785398163397301 Radian (Check conversion here)
Coefficient of friction at screw thread: 0.15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η = tan(α)/((μ+tan(α))/(1-μ*tan(α))) --> tan(0.0785398163397301)/((0.15+tan(0.0785398163397301))/(1-0.15*tan(0.0785398163397301)))

Evaluating ... ...

η = 0.340061358115195

STEP 3: Convert Result to Output's Unit

0.340061358115195 --> No Conversion Required

FINAL ANSWER

0.340061358115195 ≈ 0.340061 <-- Efficiency of power screw
