Body:Variable Section Sweep

[frankbuck]

I have seen this instruction for making gears but have not found the mouse clicks to generate the proper type.
Create a new feature:Body:Variable Section Sweep,Pivot Direction
When created correctly the feature appears as a protrusion.
Feature Element Data - PROTRUSION: Variable Section Sweep, Pivot Direction
Any ideas?
Thank you

can you elaborate this? Seems like you got an old (pre wf) instruction, right?

I downloaded this from the Pro-E support website. The original files appear to be German so perhaps the translation is a bit off, I don't know what version the original file was created in.
<h2>Suggested Technique for the Creation of an Involute Gear Cutting (Three Methods)</h2>

well, since you are asking about VSS, and the thing you wrote in your first post is an example of how it used to be before WF was introduced, Anyway, first of all - do you have your trajectory? and do you have any pics of how your modell looks like right now? and maybe what you want to achive?


If possible, please be a bit more specific about what you want to know about VSS.

Tobbo,

I have attached the file with the VSS that I have been unable to duplicate.

Thanks for your time.

I do a four hour workshop on everything a VSS can do and why you never liked it. Think of it... where are the variable sections?Well i show you.

 

[tobbo]

sorry , cant open the file (I gotwf4 at the moment) . A pic would help.

Hope this helps.

 

[tobbo]

ok....I see the gearwheel and your circle shaped curves. So now what do you want to do?

If your trying to get the exact dialog box you see when you edit the definition of the VSS feature I don't think you're going to getthat when starting from scratch in WF5. The default settings for VSS will give a square tooth and the final tooth shape is controlled by section relations.

This is what I was looking for.
Maybe I can't reproduce it in WF5.

You can create the same gear geometry what won't be the same is the dialog you get fo rfeature creation.

Hello Frankbuck, this kind of feature can be made even in
Creo Elements/Pro 5.0, this VSS use a function called
BEZUGSPROFIL the yellow icone before the VSS, withing the
VSS while sketching the tooth profile also is using a
relation:

RY = D38+trajpar*(KOPFKREIS_DURCHMESSER/2-D38)
if RY < radius_grundkreis
RY = radius_grundkreis
endif
alpha = acos(radius_grundkreis/RY)
env_alpha = tan(alpha) -alpha*PI/180
sd9 = 2*RY*(dicke_teilkreis/(2*radius_teilkreis)
+env_eingriff-env_alpha)

All the parametres in this relation have been declared
in the "Local Parameter" section.

Te "PIVOTE DIR" just refers to the plane that will be
use perpendicular to the sketch plane, in this case could
be the FRONT plane or the top of this part.

The real work it's been driving by the relation and
it's local parameters.

I hope this could help you.
