- Опубликовано: 11 сен 2024
- The model shape of spur gear is possible to drive by different methods.
In this example, I would like to show you How to manage model parameters with ProProgram in Creo.

Thank you for your effort
i just make it
Я очень ждал подробностей! Супер.
I have an idea to finish all Gear connection first and then - show, hot to create parametric gears :) Stay tuned, Vladimir
Nice one man
Super and the best one sir
Hey Vlad can you make a video on spiral bevel gear using parametric equations
Thank you for your request, I will.. Stay tuned. Vladimir
Я не увидел уравнения эвольвенты. Какая форма зуба?
I did not see the involute equation. What is the shape of the tooth?
Hí, the model was created by points and the position of points was created based involute math transformation. The real 3D model is possible to find here ruclips.net/video/owArGPRzjQo/видео.html (available for download)
Note: the modeling of gear by the equation is a different technique :)
Thanks for your comment and likes -Bye, Vladimir
Please check e,g.: EDA*(P/D-((PI/(2*Z))+(2*X*TAN(ALFA)/Z)+(TAN(ALFA)-((ALFA)*PI()/180))-((TAN(\
\ACOS(EDB/EDA)))-((ACOS(EDB/EDA)*PI()/180))))) - it is involute / the model is based on involute math
All used relations are in the description under video
Bye, Vladimir
Thank you so much for all of your videos.i have a query.
1. How can I override the dimension in drawing in creo 6.?
2. If i am shawing dimension of a circle by manually it shaws only in radius. How can i change it into diameter?
Hi, thanks for your questions: add1 In the drawing select dimension and set o(as override) instead @
Add2 if you need to create Diameter dimensions in the drawing mode, please double click on the circle and middle button for placement of the value (or create diameter dimensions in the sketch and only show diameter dimensions in the drawing ;)
@@4kside thank you so much sir for your support..i tried it..but it shaws original dimension and o as a suffix..i.e. if dimenaion is 34.56 then in dimension text @D is there...if i am converting it into o then it is shawing 34.56o...can you please make a short video...it will help me..i have another query but i will ask after resolving this probpem..hope you don't mind.
@@4kside thak you so much sir.for your time and help as well...it helps me a lot.🤘now i have another query..can you please help me to solve it??
If i am exporting dwg from drg. Its ok. When i am converting pdf from that dwg (autocad) file...pdf seems to be good but when i am printing it from printer it is very light and shaw nothing in my paper...can you please solve this stuff?
You should highlight all dimensions that you are using just make side title to show dimensions...👍👍
Thanks for your idea.. I am going to post picture of all used dimensions
Please check highlighted dimensions here: ruclips.net/user/vpalffycommunity
Thanks for your kind reply I really feel good that you response to your subscribers. And thanks very much to post dimensions once a again a thank you very much.
