Hi, I have a problem in the parameterization that I can't fix.
I would like to command the number of repeats of a series (axial) through a parameter. Specifically, I made a parametric wheel and the parameter in question is the number of teeth. pro-engineer gives me error when I enter the parameter name in the menu that requires the number of repetitions as it expects a real value (and not the parameter name). the limitation is not bad because, in any case, before regenerating I go to change the parameter by reminding me then to go to manually insert the number of repetitions in the series. If I could fix it would be the last step of parameterization. thanks and greetings to all.
 
Hi. .
both:use some parameters and some functional relationships to quote in relation to the parameters...for example when I change the number of teeth automatically, at the same module, changes the primitive diameter of the wheel. the problem is that I can't insert the "n_denti" parameter as the number of repeats in the series. the strange thing is that pro-e accepts it, always in the series, when the specifics, by relation, the angular quota to vary. If you want to attach the prt file so you could take a look.
Thank you.
 
try to insert into the p48=n_denti reports, where p48 will vary it with the name of the number of repetitions of your series. if it does not work mail the prt, max wf4, we give an eye
 
I forgot, in the series do not indicate the angle, but click on the button that allows the members of the series to be fair and arranged on 360°
 
I disp but I can't because, while setting the self-space on the corner, in terms of repetitions only accepts numerical values. I posted the file. the series in question is located in the "detached group".

I refer you the correct file, in number of teeth you can vary it from relationships giving any value to n_denti.
I had to remove the rounding at the base of the tooth, because so it gave problems, insert it into the tooth sketch

Now I'm back at work. There's a little problem: I have the wf3 and can't open the file. If you don't mind too much, can you tell me what I have to change?
anyway I thank you so much for the help and advice. greetings
 
these are the relationships to be inserted:

_
p548=n_
$d0=mod_n*n_denti/(cos(a_elica))


$d3=d0*cos(atan(tan(ang_pres_n)/cos(a_elica))))

p548 is the name of the number of items in the series check that in your file it is not different.
then, as I told you, eliminates rounding
 
perfect... it works! thank you so much!! !
I did not think that "quota" could be included in the reports (number of repetitions). You were very kind. greetings
 
It was a pleasure.
If you want to do something more refined, hide all the sketches that are served for construction and leave only the primitive diameter, which serves for the coupling of the other toothed wheel, perhaps represented with a stretch-point line that will serve you in the table.
About the table setting I attach a drawing with a table that automatically shows all the parameters characteristic of the gear teeth, it can serve you as an exercise.
I hope I've made you a pleasure, I don't want to

greetings

Thank you. all very useful; this toothed wheel together with other and respective trees (and more) is an integral part of a gearbox. ..project of construction of machines! there will be to make the table! Thanks again. greetings
