The image above represents the helix angle. To calculate helix angle, two essential parameters are needed and these parameters are screw lead (S) and barrel diameter (Db).
The formula for calculating helix angle:
θ = tan-1[S / (π x Db)]
Where;
θ = Helix Angle
S = Screw Lead
Db = Barrel Diameter
Let’s solve an example;
Find the helix angle when the screw lead is 14 and the barrel diameter is 22.
This implies that;
S = Screw Lead = 14
Db = Barrel Diameter = 22
θ = tan-1[S / (π x Db)]
θ = tan-1[14/(π x 22)]
So, θ = tan-1[14/69.115]
θ = tan-1[0.202]
θ = 11.45°
Therefore, the helix angle is 11.45°.
