parametric gear design

[cliff23]

Hello everyone

I attach a cat part for construction
parametric toothed wheels with evolving toothing

just enter the following data:

z ----> tooth number
m ----> module
a ----> pressure angle
extrusion ----> thickness wheel

should be all correct, however we accept
suggestions and/or changes

Hi.
but how should you do to open it?

 

[marcofa]

You have to extract it in a folder and then open it with a casket.
sin that only works until z 30, then by a mistake on a chord

this is working

After extracting the file from the archive, I try to open it with catia but the program returns me an error signal.
I have catia v5r17, I try the other two files this afternoon. Thank you.

 

[marcofa]

I think it takes at least r19

files attached
gears rights.zip (239,5 kb, 3 visits)
helical gears.zip (606.2 kb, 3 visits)

Excuse me, but how should these two files be changed? I would like to draw a toothed wheel from the number of teeth and outer diameter!

after opening the file under parameters you find everything you want to edit.
doubleclicking on each parameter you can change it in the window.

I downloaded the files but the tooth profile is a simple approximation with circles.
How is it possible to draw a curve in a sketch knowing its equation?? ?
I looked in other discussions but apart from a macro reading points from a sheet of excel and then approximate them with a spline I found nothing

Bye!
I apologize if I stress you; playing a bit with the file I saw that I can only change the number of z teeth parameter. Is it the only editable or did I miss something?
I would change the primitive diameter or module. Is that possible?
Thank you.

Would it be risky to hope to find a parametric catpart for modeling internal gears? (see solar of an epicycloidal)
Cliff23 did a good job for the outside, could continue the work with the interior, perhaps as a Christmas gift.
happy year to all

Dear boys.. I wanted to ask you an info.. but the cat turns on pc mac? or do you have to oparate the most classic of the partition operations of the hd?=
thanks for the info.

 

[marcofa]

Look at you wrong post.

 

[dante19]

and to complete the work would miss the dense conical wheels!!!

you guys have a conical gear file? I'm doing a project but I can't draw them...I'm freaking help me pleaseeeee
