Parameters: 

No_of_teeth - 32
Normal_module - 2.8
Pitch_diameter - 100
Normal_pressure_angle - 20
Helix_angle - 26
Width - 25


Helical Gear formula:-

Transverse_module = normal_module/cos(helix_angle)
Normal_circular_pitch = pi*normal_module
Transverse_circular_pitch = pi*transverse_module
Transverse_pressure_angle = atan((tan (normal_pressure_angle))/(cos(helix_angle)))
Outer_diameter = pitch_diameter+(2*normal_module)
Root_diameter = pitch_diameter-(2*1.25*normal_module)
Base_diameter = pitch_diameter*cos(transverse_pressure_angle)
Normal_tooth_thickness = (pi*normal_module)/2
Transverse_tooth_thickness = (pi*transverse_module)/2
Lead = pi*pitch_diameter/tan(Helix_angle)

Ivolute curve equation:

Base_radius = Base_diameter/2
Angle = t*90
Cir_len = (PI*Base_radius*t)/2
X_PNT =Base_radius*cos(angle)
Y_PNT =Base_radius*sin(angle)
x = X_PNT + (Cir_len*sin(angle))
y = Y_PNT - (Cir_len*cos(angle))
z = 0
