as from title... .

I know how to draw the tooth profile, even if it would be to draw it on a conical surface, but I can't make the profile

Does anyone know if there is something (free) already done or if there is a guide to do it?

Thank you very much
 
And then... because the files downloaded from nozag, which leans on tradeparts, there is no profile of the tooth ... etc. ... There is only one cone
 
Hello, everyone. as the previous colleague I have to model a pair of toothed conical helical wheels. to draw the tooth profile I have no problems, but I can not realize the spiral along which it develops: Does anyone know how I can make it?
Thank you in advance
 
I am drawing a cylindrical toothed wheel with evolving tooth, I would like to draw a conical toothed wheel with evolving straight teeth.......
I miss a few steps
 
Do you think the creation of the tooth in my video is right?
https://www.youtube.com/watch?v=0s57evlt99gI have seen, that the circles for the construction of the tooth, should start from the conjunction of the perpendicular nets to the tooth
screenshot.9.webpBut, by doing so, increase the diameter... and the toothing gets all high...

the external diameter measures 164.76 instead of 116.5
the primitive diameter measures 152.74 instead of 108

and in the end the tooth results so...wrong

in my video, the center of the circles (rings outside the cone) I designed them starting from 108 and holding the circles head and that of concentric foot to 108 and matching the two points required by the drawing
 
Hi.

You ask me too much... I only have a few more confused memories and then I shouldn't have had to drink that glass of wine at lunch!

I guess there's something to see in the tracking, two tips:

1) go to the misumi site, to the voice gears, configure the data by inserting the same as you designed, download the file in step format and compare it to your result and try to figure out where you are wrong.

2) Find a valid text with Gear Tracking (I recommend the fourth volume technical drawing course of prof. bartolo Pacetti editions hoepli: outside catalog, you can find it in some reimanders library or in university engineering libraries)

If you're interested, send me your e-mail that I'll send you some trash of mine.

Hi.
look at this image of how I created the toothed pinion, first creates the tooth compartment with the evolving system.
greetings

Hi.

I took a look at the manual that recommended me gianni55
Unfortunately, the only question I have left, is exactly what I needed, I did not understand how to draw the tooth on the tooth wheel.
In the end, I decomposed a conical toothed wheel created automatically by solidworks, and found the data I needed.

from the images of Dorian, for now, I can't understand much.

I recreated the video with the directions I think right (if they are right) https://youtu.be/12azxgghbsoIf anyone finds mistakes, and warns me, I'd be grateful.

Thank you.

Hello clatso
I watched the video and big lines it's okay it's logical that the more adoprious points for the more evolved the tooth profile is accurate.
what I did not understand is the 95° line at the beginning when it created the lines at 20° of the pressure angle.
However, the tooth can be created in several ways (I speak with catia) the important point of the evolving.
 
Hi.
Thank you!


I designed the evolving starting from 95° instead of 90°, because thus making the tooth point coincident with the primitive diameter, it is already in position for the mirrors (half of the tooth) , otherwise I should have rotated later the figure before the mirroring.

I hope it's logical....... .

the tooth can also be created in several ways, but apart from precision, they must be equal to the end.

Hello clatso
after sending the message I realized why you left from 95° but now the message was gone. the construction is right given the step of 20° six started from 1/4 therefore 5° which is the point of the pressure angle therefore what you have done is correct good year

if you need dense wheels of various kinds you find them already made on traceparts or on the sites of the manufacturers of commercial pinions.
If instead your goal is to customize the tooth and move the profile I would say that it is good that you learn the construction, quite complicated of the tooth on the conical face.

Unfortunately on traceparts the toothed wheels see them with teeth but when the discharges are cylinders. I don't have to model dense wheels now I'm retired, it's just exercise, and I don't see any difficulty shaping a straight toothed sprocket. happy year also to you
