Learn how to create an internal spur gear in creo parametric. Hope you benefit from it and learn some new concepts.
Relations Equations
circular_pitch = pi*module /*circular pitch
addendum = module /*addendum
dedendum = 1.25*module /*dedendum
refrence_dia = module*no_of_teeth /*refrence dimeter
tip_dia = refrence_dia+2*addendum /*tip diameter
root_dia = refrence_dia-2*dedendum /*root_diameter
base_dia = refrence_dia*cos(press_angle) /*base_diameter
root_fillet = 0.38*module /*root fillet radius
semitopping = 0.1*module
tooth_thick = circular_pitch/2 /*tooth thickness
Involute Curve Profile Equations
theta = 90*t
angle_ratio = theta/360
S = angle_ratio*pi*base_dia
base_radius = base_dia/2
Xc = base_radius*cos(theta)
Yc = base_radius*sin(theta)
X = Xc+(S*sin(theta))
Y = Yc-(S*cos(theta))
