Let's design Rack and pinion gear in Creo Parametric
relations for spur gear:
pressure_angle = 14.5° & 20° (Standard value)
module = reference_dia/no_of_teeth /*module
reference_dia = module*no_of_teeth /*reference_dia
circular_pitch = pi*module /*circular pitch
addendum = module /*addendum
dedendum = 1.25*module /*dedendum
tip_dia = reference_dia+2*addendum /*tip diameter
root_dia = reference_dia-2*dedendum /*root_diameter
base_dia = reference_dia*cos(pressure_angle) /*base_diameter
root_fillet = 0.38*module /*root fillet radius
semitopping = 0.1*module
teeth_thickness = circular_pitch/2 /*teeth thckness
clearance = dedendum - addendum
Involute equation:
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))
Z = 0

Really useful..and genuine content..please keep sharing such videos🎉

Thank You sir for putting this tutorial

[@vikassinha9557]

Thank you sir

[@infinitestudycenter4942]

Great sir, while creating if you give more insides about commands then it will be helpful

I really like your video and you provided a lot of information. Thank You. I do wish that the formulas lead themselves to being converted to imperial measurements would you be interested in converting this to imperial from metric with the updated formulas and geometry?

@cadx request you to make a video on bevel gear making using parameter as you made spur and helical gears.

[@AbdulRahman-nv4xd]

Sir,your tutorials are very helpful,can you do for internal gears?

[@CADxTraining]

I am so busy these days, not getting enough time to do any new things.

Hi Mr. I am new in Creo 4. I am confuse. Why after I give dimension to my sketch, the line still be able to deform? Let say my line is 10mm, if I drag the end point it will be larger or smaller than 10mm. I have to manually lock each line. It is a very time consuming job which is kinda different with previous cad software (inventor)

[@CADxTraining]

Go to File-option-sketcher and select "lock user defined dimension"

[@user-jv9xy3ek5v]

hello Is it available in the wildfire version other than the cleo version? An invalid symbol 'module' was found when substituting it into the relational expression.' A phrase appears Any workaround? Please reply if you have any. take care

[@CADxTraining]

If you follow the same procedure it will work in wildfire. There is no difference in relation between wildfire and Creo.

[@lucabreggi]

how are the relationships for the helical rack?

[@CADxTraining]

I need to check that

[@koenamorake723]

Hello. I am on Creo 3.0 and I am struggling with the step you did at 09:42 (putting dimensions for teeth thickness

[@CADxTraining]

It is same in all the versions. You just need to put arc length there.

[@koenamorake723]

@@CADxTraining when I click first point point and second point, and then the arc, the dimension is not appearing. Maybe I am doing something wrong. Please help 🙏🏾

[@CADxTraining]

Click the first point and hold the control key. Then click on the second point and click on the arc.
