elliptical toothed wheel

[mmvmorandi]

Hello everyone.. .
...from a while I grow up trying to create a model of
Elliptical toothed wheel m 2.5

Any idea how to do that?

Thank you.

model "serio" with profile of the right teeth etc. etc. or something that gives the idea (more or less carefully)?

 

[mmvmorandi]

I'd need a serious tooth profiling model.
I don't know if you can use the inventor's automatic construction components.
Do you have any advice?

 

[Catafratto]

No, if it's serious, I don't know what to do... apart from trying the theoretical graphic construction for each tooth (on primitive elliptical? I have to pull out the school books). Sorry.

:36_1_4::36_1_25:
but how many teeth has this wheel?

 

[mmvmorandi]

49 teeth...

 

[mmvmorandi]

the construction of the wheel in three-dimensional has been carried out, now the problem is to find the transmission ratio to create the simulation.
the point is that the transmission ratio is as variable as I do? ?

ps: for the creation it is necessary to draw the outer and internal ellipse, to create the profile of the tooth and to interpolate it on a circle with diameter equal to the maximum of the ellipse.

If I'm not mistaken, the teeth are different, so it shouldn't be enough to bring the teeth back to step, but they should be rebuilt one by one... at least for a quarter of the wheel (then it mirrors). .
Anyway, curious, I looked on the net and found a pantry with some formulas, if you need the allego.

thank you, attach it so we see if there is any extra indication! I also did an internet search, but there is not much information about it!
Thank you.

Here we go. I can't judge the reliability, though.
I hope you're useful.
