Lead of Screw given Helix angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lead of Power Screw = tan(Helix angle of screw)*pi*Mean Diameter of Power Screw
L = tan(α)*pi*d_m
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

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

Lead of Power Screw - (Measured in Meter) - Lead of Power Screw is the linear travel the nut makes per one screw revolution and is how power screws are typically specified.
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.
Mean Diameter of Power Screw - (Measured in Meter) - Mean Diameter of Power Screw is the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface.

STEP 1: Convert Input(s) to Base Unit

Helix angle of screw: 4.5 Degree --> 0.0785398163397301 Radian (Check conversion here)
Mean Diameter of Power Screw: 46 Millimeter --> 0.046 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = tan(α)*pi*d_m --> tan(0.0785398163397301)*pi*0.046

Evaluating ... ...

L = 0.011373440383317

STEP 3: Convert Result to Output's Unit

0.011373440383317 Meter -->11.373440383317 Millimeter (Check conversion here)

FINAL ANSWER

11.373440383317 ≈ 11.37344 Millimeter <-- Lead of Power Screw

Mean Diameter of Power Screw

LaTeX Go Mean Diameter of Power Screw = Nominal diameter of screw-0.5*Pitch of power screw thread

Nominal Diameter of Power Screw

LaTeX Go Nominal diameter of screw = Core diameter of screw+Pitch of power screw thread

Core Diameter of Power Screw

LaTeX Go Core diameter of screw = Nominal diameter of screw-Pitch of power screw thread

Pitch of Power Screw

LaTeX Go Pitch of power screw thread = Nominal diameter of screw-Core diameter of screw

Lead of Screw given Helix angle Formula

LaTeX Go

Lead of Power Screw = tan(Helix angle of screw)*pi*Mean Diameter of Power Screw
L = tan(α)*pi*d_m

Define Lead of a Screw?

Lead is the axial advance of a helix or screw during one complete turn (360°) The lead for a screw thread is the axial travel for a single revolution. Pitch is defined as the axial distance between adjacent threads on a helix or screw
