Hello, everyone.
I've never drawn a toothed wheel, I'm trying, I've turned the drawing in the annex, but it seems to me that there is something that is not square.
What do you think?

Thank you so much!

you can always use a excel sheet and import the curve generated in table excels.
I should have a file that suits you.
I need to check.

I should develop it with solidworks, but I don't get it. ...[/quotes

the modeling of a toothed wheel with solidwrks is also described on the turnsincasa kirone vol.ii; tomorrow, if I remember, I'll scan the part you're interested in.

I've got it at home. I'll look at it as soon as I can.
But here I do not understand what the primitive diameter is.
38,1 or 41,275 or 32,295.
I have performed tutorials with dense wheels and came to me, maybe this is different because it is an internal gear.
Thank you!
 
a page of the many http://www.edutecnica.it/meccanica/ingranaggi/ingranaggi.htmfrom the page in question is called the primitive diameter of a toothed wheel the diameter associated with the circumference that passes where the width of the teeth is equal to the width of the compartments.
do not recognize the primitive diameter is severe

the construction with solidworks is an exercise that leaves the time it finds because it is enough to insert in the table the constructive data and the specialized workshop you build them without needing the model.

there are special programs that shape the gear as kisssoft
 
I'm not a mechanical designer, I'm just practicing on solidworks.
The fact is that this gear doesn't come to me in any way. and from that which my
perplexity on measures.
I need to draw with solidworks.
Tomorrow I look at the pages you sent me.
ps: I have the chironi volume 1 .

thank you all
 
Bye.
I scanned the part of building a toothed wheel with solidworks.
Unfortunately the file is about 24 m and doesn't let me upload it to the forum.
If you need to send me an mp and I'm gonna turn it around. analogous speech for anyone who needs it.

Meanwhile I attach the excel file of the construction of the toothed wheel.

In the meantime, I appreciate how to use the data you gave me I work on it.
You were very kind.
However, I just need to draw the tooth for a sketch, not for production, so it can be much less defined.
Thank you!
 
However the whole is built on the basic said construction diameter that is not the basic one or the primitive. I would say that you can quickly parameterize the model of straight teething.

Perhaps you could have a simple representation of what the execel sheet points indicate?

Thank you.
 
If you take your beautiful excel and insert scatter chart using the first two columns you will find out by yourself... .Screenshot_20230424_193417.webpare the points that define the evolved.
better import a nice step from free to with the fcgea module. lighter and he thinks about giving you all the gear and all the corrections.

I thank you for the answer but I wanted an indication of the various angles that are indicated in the table, so that I have a clearer idea of how the evolved through the intersection of the various points is constructed.

The only angle is pressure. the other are all x y....mm

hi mechanics mg.. I wanted to ask you, if you can choose different forms from the table of uni en iso 6586 - 69, that is perhaps with values that differ a lot for example with 2,1134 mm or 4,897 or 0,468786 etc.. to obtain certain moving coefficients desired together with the desired displacement interchange, and the same with pressure angles, if you can choose values other than 20 or 15 or 25 degrees i.e. 23.546 etc. and also dedendum value that is not 1,25 * m and/or (7/6) * m if there are tools that can give a cut to the wheels respecting those values that are not commonly used and standardized giving any truncating. .
